The subject of graduate qualification work is “Energy-Efficient Technologies for Sustainable Reconstruction of Historical Buildings in Saint-Petersburgâ€. The presented work is devoted to studying water efficiency innovations, that can be implemented to historical buildings of Saint-Petersburg, to improve the environmental impact, and design methodology implementation of efficient water management as an element of sustainability in Russia. The research set the following goals: 1. Studying water innovative management, analyze its advantages and disadvantages to investigate the methodology of implementation rainwater collection systems for historical buildings and buildings with local, federal historical heritage status of Saint-Petersburg Committee on State Control, Use and Protection of Monuments of History and Culture for reconstruction, renovation or overhaul projects. 2. The aggregate of this information confirmed the obligatoriness for further research in terms of developing a mathematical model of rainwater and meltwater consumption for technical uses toilet flushing of residential houses. 3. Design the methodology for the implementation of efficient water management as an element of sustainable development in Russia. Since 1990, energy-efficient development concepts have constituted both a turning point in civil engineering and a challenge for an environmentally friendly future. Energy and water currently play an essential role in the sustainable economic growth of the world in general and Russia in particular: the efficiency of the water supply system is the second most important parameter for energy consumption according to the British assessment method, while the water-energy nexus has been identified as a focus for accelerating sustainable growth and developing effective, innovative solutions. The activities considered in this article were aimed at organizing and executing the renovation of the property in residential buildings located in St. Petersburg, specifical buildings with local or federal historical heritage status under the control of the St. Petersburg Committee for the State Inspection and Protection of Historic and Cultural Monuments (KGIOP) and UNESCO. Even after reconstruction, these buildings still fall into energy efficiency class D. Russian Government Resolution No. 87 on the structure and required content of project documentation contains a section entitled ‘Measures to ensure compliance with energy efficiency and equipment requirements for buildings, structures, and constructions with energy metering devices’. Mention is made of the need to install collectors and meters, which only calculate energy, neglecting the main purpose: to make buildings more energy-efficient, potentially even energy efficiency class A. The least-explored aspects of energy-efficient technology in the Russian Federation remain the water balance and the possibility of implementing rain and meltwater collection systems. These modern technologies are used exclusively for new buildings due to a lack of government directive to create project documentation during the planning of major renovations and reconstruction that would include the collection and reuse of rainwater. Energy-efficient technology for rain and meltwater collection is currently applied only to new buildings, even though research has proved that using rainwater is safe and offers a huge step forward in terms of eco-efficiency analysis and water innovation. Where conservation is mandatory, making changes to protected sites is prohibited. In most cases, the protected site is the cultural heritage building itself, including the main walls and roof. However, the installation of a second water supply system and collection of rainwater would not affect the protected building itself. Water efficiency in St. Petersburg is currently considered only for the installation that regulates the flow of the pipeline shutoff valves. The development of technical guidelines for the use of grey- and/or rainwater to meet the needs of residential buildings during reconstruction or renovation is not yet complete. The ideas for water treatment, collection, and distribution systems presented in this article should be taken into consideration during the reconstruction or renovation of residential cultural heritage buildings under the protection of KGIOP and UNESCO. The methodology applied also has the potential to be extended to other cultural heritage sites in northern countries and lands with an average annual rainfall of over 600 mm to cover average toilet-flush needs.[1] The sustainable challenge of Saint-Petersburg follows improving environmental and living quality due to developing renewable power resources. Because of climate conditions and increasing precipitation, the main renewable resource of the Northern Capital is water. The research work was conducted from October 2018 till May 2020. The analysis was executed by the method of mathematical modeling with the use of Microsoft Excel software. The study resulted into the sufficient rainwater collection for installment in residential buildings located in St. Petersburg, that are historical buildings and buildings with the local, federal historical heritage status of Saint-Petersburg Committee on State Control, Use and Protection of Monuments of History and Culture due to improving energy-efficiency and sustainability for the project of reconstruction or renovation. There was developed a methodology, that explains the sustainable approach of upgrading historical buildings due to reconstruction or renovation and overall environmental impact. The outcome of the research work affects the Sustainable Development Goals of the Russian Federation, as No.6 - preserving and fine cleaning water resources; No.11 - sustain human settlements and cities; No.12 - sustainable consumption and production; No.13 - Climate Change challenge; No.14 sustainable use of oceans and seas. The model of rainwater and meltwater collection for secondary use for toilet flush needs due to re-equipment, reconstruction or renovation of the residential historical buildings will introduce renewable water resources usage, encourage sustainable development of Saint-Petersburg, save clean potable water, create a new resource - rainwater and meltwater, relieve pressure on rain sewer networks, develop the economy, and increase the quality of life of citizens.

Data on zoobenthos organisms of 36 urbanized lakes were used. The predominant group by species composition in the zoobenthos community is insects, making up 53% of the total species composition, chironomids were the most frequent. The most frequently occurring and red-listed species of zoobenthos organisms were found. Zoobenthos numbers varied from 10 to 2800 eq/m2 in different water bodies; biomass values varied from 0.04 to 61.15 g/m3. According to the Shannon and Simpson species diversity indices, most of the lakes belong to the category of polluted with stable communities. The lake ecosystems located in the Novo-Savinovsky and Kirovsky districts of Kazan and belonging to the first supra-floodplain terrace of the Kazanka River and the Volga River are among the most significant in terms of species diversity of biological resources. The biological resources of lakes in Kazan, which are subjected to strong anthropogenic load, need to be protected, and the lakes need to be improved and rationally used. В ходе исследования анализировались данные по видовому составу и количественным характеристикам зообентоса на основе данных экологической инвентаризации и паспортизации г. Казани. Использованы данные об организмах зообентоса 36 урбанизированных озер. Преобладающей группой по видовому составу в зообентосном сообществе являются насекомые, составляющие 53% от общей видового состава, наиболее часто встречались хирономиды. Выявлены наиболее часто встречающиеся и краснокнижные виды организмов зообентоса. Значения численности зообентоса изменялось от 10 до 2800 экз./м2 на разных водных объектах; значение биомассы изменялось от 0,04 до 61,15 г/м3. Согласно индексам видового разноообразия Шеннона и Симпсона, большая часть озер относится к категории загрязненных с устойчивым сообществом. К наиболее значимым по видовому разнообразию биологических ресурсов относятся озёрные экосистемы, расположенные территориально в Ново-Савиновском и Кировском районах г. Казани, относящиеся к первой надпойменной террасе реки Казанки и Волги. Биоресурсы озёр г. Казани, подвергаемые сильной антропогенной нагрузке, нуждаются в охране, а озера – в благоустройстве и рациональном использовании. Международный научно-исследовательский журнал, Выпуск 10 (136) 2023

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2020Publisher:Zenodo Authors: Polishchuk V.M.; Shvorov S.A.; Krusir G.V.; Davidenko T.S.;The aim of the work is to increase biogas output and generation of electricity in biogas plants due to the joint fermentation of cattle manure with winemaking waste. To achieve this goal, the following tasks have been solved: the biogas yield from cattle manure with winemaking waste was determined during periodic loading of the digester; based on the obtained experimental data, a mathematical model was calibrated to estimate the biogas yield during fermentation of cattle manure with the addition of winemaking waste. Because of the studies, it had been found that when manure was fermented with part of the water replaced in the substrate 2% of the winemaking waste, the fermentation dynamics in the substrate are similar to the fermentation of pure cattle manure. Biogas obtained by fermentation of manure with the addition of 2%, 6.5% and 13% of wastewater from wine production instead of water in the first day of fermentation either did not burn at all or burned poorly. The addition of winemaking waste to a substrate based on manure in an amount of 13% allows increasing the maximum biogas yield by a third to 1,372 l/(hrkg dry organic matter). The significance of the research results lies in the fact that the use of winemaking waste as a substrate will allow a third increase in biogas output and power generation, and a reduction in the payback period of a 4,4 MW biogas plant using the green tariff to 6,5 years.

The temperature of raw water supplied to the chemical water treatment at most CHP plants should not exceed 30-40 °C. Fulfillment of this condition is not always possible, and it becomes necessary to analyze and adjust the operating modes of turbines, which provide the most effective heating of water in the built-in bundles. Such an analysis can be carried out quite simply on the basis of operational data and a mathematical model of the condenser developed at the Department of Heat Engineering and Hydraulics of VyatSU. In this paper, an analysis algorithm is considered based on the actual data obtained during the tests of the condenser of the PT-80-130 turbine unit in the mode of its operation according to the electrical schedule, conclusions are drawn from the analysis results. Один из наиболее надёжных способов повышения эффективности ТЭЦ -- организация подогрева сырой (подпиточной) воды в конденсаторах теплофикационных турбоустановок при одновременной подаче циркуляционной воды через основные пучки. Температура сырой воды, подаваемой в цех химводоочистки, на большинстве ТЭЦ не должна превышать 30 - 40\\оС. Выполнение данного условия не всегда возможно, и возникает необходимость анализа и корректировки режимов эксплуатации турбоустановок, обеспечивающих наиболее эффективный подогрев воды во встроенных пучках. Проведение такого анализа достаточно просто можно выполнить на основе эксплуатационных данных и математической модели конденсатора, разработанной на кафедре теплотехники и гидравлики ВятГУ. В данной работе рассмотрен алгоритм проведения анализа на основе фактических данных, полученных при испытаниях конденсатора турбоустановки ПТ-80-130 в режиме её работы по электрическому графику, сделаны выводы по результатам анализа.

Соблюдение температурного режима в допустимых пределах при сушке кормов позволяет сохранить в них питательные вещества, в том числе витамины. Сушка зерна или других кормовых средств – достаточно энергозатратный способ их заготовки. Использование геотермальной воды как источника тепла для сушки представляется достаточно эффективным в плане энергосбережения и снижения физических затрат. Высокая температура геотермальной воды (87-90°С), при прохождении по трубам, уложенным в полу при помощи бетонной стяжки, способствует прогреву и сушке растительной продукции. Высокий уровень температурного режима и нормативы качества термальной воды позволяют использовать ее при реализации способа сушки зерна и различных видов рассыпных комбикормов. Кроме того, применение термальной воды в качестве тепловой энергии напольного водяного теплого пола является одним из самых энерго-и ресурсосберегающих способов при сушке зерна и различных видов сочных кормов. Предлагаемый кондуктивный способ сушки зерна представлен по принципу соприкосновения сырья с нагретой поверхностью, при котором обычно наблюдаются большие расходы топлива, но в нашем случае тепловым агентом служит термальная вода, при котором энергетические затраты сводятся к минимуму. Использование предложенного способа предполагает применение различного вида ворошителей, что в свою очередь сопряжено с дополнительными энергетическими затратами. Наряду с этим, выявлена низкая производительность сушилки, связанная с невысокой температурой и неравномерного ее распределения по бетонному полу. В исследованиях статьи предлагаются результаты и эффективность применения способа сушки и приготовления разных кормовых средств с использованием тепловой энергии геотермальной воды напольного водяного отопления. Drying of feed products helps to remove moisture and prevents biochemical processes in plant cells that contribute to the destruction of proteins, fats and carbohydrates. Compliance with the temperature regime within acceptable limits when drying feed allows you to preserve nutrients in them, including vitamins. Drying grain or other feed products is a fairly energy–intensive way of harvesting them. The use of geothermal water as a heat source for drying seems to be quite effective in terms of energy saving and reducing physical costs. The high temperature of geothermal water (87-90°C), when passing through pipes laid in the floor with a concrete screed, contributes to the heating and drying of plant products. The high level of the temperature regime and the quality standards of thermal water allow it to be used in the implementation of the method of drying grain and various types of loose compound feeds. The proposed conductive method of drying grain is presented according to the principle of contact of raw materials with a heated surface, in which large fuel costs are usually observed, but in our case thermal water serves as a thermal agent, in which energy costs are minimized. The use of the proposed method involves the use of various types of agitators, which in turn involves additional energy costs. Along with this, the low productivity of the dryer was revealed, due to the low temperature and its uneven distribution on the concrete floor. In the research of the article, the results and effectiveness of the application of the method of drying and preparation of various feed products using the thermal energy of geothermal water of underfloor water heating are proposed.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2023Publisher:ООО Цифра The relevance of the topic is determined by the existing problems in the creation of new environmentally friendly technological processes to ensure the rational use of available renewable resources. Due to the rapid depletion of non-renewable resources, and subsequent pollution of the environment, people faced the question of reorganizing their activities and reducing the harmful effects by using waste resources to create a new type of fuel. The subject of the study is the subsequent utilization of wastewater in the production of liquid biofuel. Various methods of organizing wastewater disposal were examined and their main common disadvantages were characterized. It was established that when applying traditional mechanical and biological treatment methods, there is a necessity in additional treatment of wastewater from biogenic elements and in improvement of methods of treatment and utilization of their sludge. As a result of the research, it was concluded that the application of traditional mechanical and biological treatment methods necessitates additional treatment of wastewater from nutrients and improvement of treatment and disposal of sludge. As one of the most promising methods of additional treatment, it was proposed to use wastewater as a medium for cultivation of energy microalgae in closed-type photobioreactors with subsequent production of liquid biofuel of the third generation. Актуальность темы определяется наличием проблем в создании новых экологически безопасных технологических процессов для обеспечения рационального использования имеющихся возобновляемых ресурсов. Из-за быстрого истощения невозобновляемых ресурсов, в последующем загрязнении окружающей среды, перед человеком встал вопрос о реорганизации своей деятельности и уменьшения пагубных последствий путем применения отработанных ресурсов для создания нового вида топлива. Предметом исследования является последующее использование сточных вод в производстве жидкого биотоплива. Были рассмотрены различные методы организации водоотведения, охарактеризованы их основные общие недостатки. Выяснилось, что при применении традиционных механических и биологических методов очистки возникает необходимость в доочистке сточных вод от биогенных элементов и в усовершенствовании способов обработки и утилизации их осадков. В итоге исследования был сделан вывод, что при применении традиционных механических и биологических методов очистки возникает необходимость в доочистке сточных вод от биогенных элементов и в усовершенствовании способов обработки и утилизации их осадков. Как один из самых перспективных методов доочистки предложено использование сточных вод как среды для культивирования энергетических микроводорослей в фотобиореакторах закрытого типа с последующим производством жидкого биотоплива третьего поколения.

New principles for design of heat and mass transfer equipment in the version with a movable packing of heat exchange elements (fluidized bed packing "gas - liquid - solid body") placed in the packed bed were developed, which allows self-cleaning of the working surfaces and walls of the heat and mass transfer equipment HMT. This new solution, when working with outdoor air and solutions of absorbents, seems to be a fundamentally important condition for maintaining the working capacity of solar absorption systems. The new schemes of absorber with internal steam cooling allowing the improvement of the new scheme of the alternate refrigerating system were developed. Comparative analysis based on the methodology of the "Life Cycle Assessment" (LCA) showed that new, developed solar systems provide the considerable decrease in energy consumption, their use leads to the decrease of exhaustion of natural resources, influences less global climate change.

The subject of graduate qualification work is “Energy-Efficient Technologies for Sustainable Reconstruction of Historical Buildings in Saint-Petersburgâ€. The presented work is devoted to studying water efficiency innovations, that can be implemented to historical buildings of Saint-Petersburg, to improve the environmental impact, and design methodology implementation of efficient water management as an element of sustainability in Russia. The research set the following goals: 1. Studying water innovative management, analyze its advantages and disadvantages to investigate the methodology of implementation rainwater collection systems for historical buildings and buildings with local, federal historical heritage status of Saint-Petersburg Committee on State Control, Use and Protection of Monuments of History and Culture for reconstruction, renovation or overhaul projects. 2. The aggregate of this information confirmed the obligatoriness for further research in terms of developing a mathematical model of rainwater and meltwater consumption for technical uses toilet flushing of residential houses. 3. Design the methodology for the implementation of efficient water management as an element of sustainable development in Russia. Since 1990, energy-efficient development concepts have constituted both a turning point in civil engineering and a challenge for an environmentally friendly future. Energy and water currently play an essential role in the sustainable economic growth of the world in general and Russia in particular: the efficiency of the water supply system is the second most important parameter for energy consumption according to the British assessment method, while the water-energy nexus has been identified as a focus for accelerating sustainable growth and developing effective, innovative solutions. The activities considered in this article were aimed at organizing and executing the renovation of the property in residential buildings located in St. Petersburg, specifical buildings with local or federal historical heritage status under the control of the St. Petersburg Committee for the State Inspection and Protection of Historic and Cultural Monuments (KGIOP) and UNESCO. Even after reconstruction, these buildings still fall into energy efficiency class D. Russian Government Resolution No. 87 on the structure and required content of project documentation contains a section entitled ‘Measures to ensure compliance with energy efficiency and equipment requirements for buildings, structures, and constructions with energy metering devices’. Mention is made of the need to install collectors and meters, which only calculate energy, neglecting the main purpose: to make buildings more energy-efficient, potentially even energy efficiency class A. The least-explored aspects of energy-efficient technology in the Russian Federation remain the water balance and the possibility of implementing rain and meltwater collection systems. These modern technologies are used exclusively for new buildings due to a lack of government directive to create project documentation during the planning of major renovations and reconstruction that would include the collection and reuse of rainwater. Energy-efficient technology for rain and meltwater collection is currently applied only to new buildings, even though research has proved that using rainwater is safe and offers a huge step forward in terms of eco-efficiency analysis and water innovation. Where conservation is mandatory, making changes to protected sites is prohibited. In most cases, the protected site is the cultural heritage building itself, including the main walls and roof. However, the installation of a second water supply system and collection of rainwater would not affect the protected building itself. Water efficiency in St. Petersburg is currently considered only for the installation that regulates the flow of the pipeline shutoff valves. The development of technical guidelines for the use of grey- and/or rainwater to meet the needs of residential buildings during reconstruction or renovation is not yet complete. The ideas for water treatment, collection, and distribution systems presented in this article should be taken into consideration during the reconstruction or renovation of residential cultural heritage buildings under the protection of KGIOP and UNESCO. The methodology applied also has the potential to be extended to other cultural heritage sites in northern countries and lands with an average annual rainfall of over 600 mm to cover average toilet-flush needs.[1] The sustainable challenge of Saint-Petersburg follows improving environmental and living quality due to developing renewable power resources. Because of climate conditions and increasing precipitation, the main renewable resource of the Northern Capital is water. The research work was conducted from October 2018 till May 2020. The analysis was executed by the method of mathematical modeling with the use of Microsoft Excel software. The study resulted into the sufficient rainwater collection for installment in residential buildings located in St. Petersburg, that are historical buildings and buildings with the local, federal historical heritage status of Saint-Petersburg Committee on State Control, Use and Protection of Monuments of History and Culture due to improving energy-efficiency and sustainability for the project of reconstruction or renovation. There was developed a methodology, that explains the sustainable approach of upgrading historical buildings due to reconstruction or renovation and overall environmental impact. The outcome of the research work affects the Sustainable Development Goals of the Russian Federation, as No.6 - preserving and fine cleaning water resources; No.11 - sustain human settlements and cities; No.12 - sustainable consumption and production; No.13 - Climate Change challenge; No.14 sustainable use of oceans and seas. The model of rainwater and meltwater collection for secondary use for toilet flush needs due to re-equipment, reconstruction or renovation of the residential historical buildings will introduce renewable water resources usage, encourage sustainable development of Saint-Petersburg, save clean potable water, create a new resource - rainwater and meltwater, relieve pressure on rain sewer networks, develop the economy, and increase the quality of life of citizens.

Data on zoobenthos organisms of 36 urbanized lakes were used. The predominant group by species composition in the zoobenthos community is insects, making up 53% of the total species composition, chironomids were the most frequent. The most frequently occurring and red-listed species of zoobenthos organisms were found. Zoobenthos numbers varied from 10 to 2800 eq/m2 in different water bodies; biomass values varied from 0.04 to 61.15 g/m3. According to the Shannon and Simpson species diversity indices, most of the lakes belong to the category of polluted with stable communities. The lake ecosystems located in the Novo-Savinovsky and Kirovsky districts of Kazan and belonging to the first supra-floodplain terrace of the Kazanka River and the Volga River are among the most significant in terms of species diversity of biological resources. The biological resources of lakes in Kazan, which are subjected to strong anthropogenic load, need to be protected, and the lakes need to be improved and rationally used. В ходе исследования анализировались данные по видовому составу и количественным характеристикам зообентоса на основе данных экологической инвентаризации и паспортизации г. Казани. Использованы данные об организмах зообентоса 36 урбанизированных озер. Преобладающей группой по видовому составу в зообентосном сообществе являются насекомые, составляющие 53% от общей видового состава, наиболее часто встречались хирономиды. Выявлены наиболее часто встречающиеся и краснокнижные виды организмов зообентоса. Значения численности зообентоса изменялось от 10 до 2800 экз./м2 на разных водных объектах; значение биомассы изменялось от 0,04 до 61,15 г/м3. Согласно индексам видового разноообразия Шеннона и Симпсона, большая часть озер относится к категории загрязненных с устойчивым сообществом. К наиболее значимым по видовому разнообразию биологических ресурсов относятся озёрные экосистемы, расположенные территориально в Ново-Савиновском и Кировском районах г. Казани, относящиеся к первой надпойменной террасе реки Казанки и Волги. Биоресурсы озёр г. Казани, подвергаемые сильной антропогенной нагрузке, нуждаются в охране, а озера – в благоустройстве и рациональном использовании. Международный научно-исследовательский журнал, Выпуск 10 (136) 2023

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2020Publisher:Zenodo Authors: Polishchuk V.M.; Shvorov S.A.; Krusir G.V.; Davidenko T.S.;The aim of the work is to increase biogas output and generation of electricity in biogas plants due to the joint fermentation of cattle manure with winemaking waste. To achieve this goal, the following tasks have been solved: the biogas yield from cattle manure with winemaking waste was determined during periodic loading of the digester; based on the obtained experimental data, a mathematical model was calibrated to estimate the biogas yield during fermentation of cattle manure with the addition of winemaking waste. Because of the studies, it had been found that when manure was fermented with part of the water replaced in the substrate 2% of the winemaking waste, the fermentation dynamics in the substrate are similar to the fermentation of pure cattle manure. Biogas obtained by fermentation of manure with the addition of 2%, 6.5% and 13% of wastewater from wine production instead of water in the first day of fermentation either did not burn at all or burned poorly. The addition of winemaking waste to a substrate based on manure in an amount of 13% allows increasing the maximum biogas yield by a third to 1,372 l/(hrkg dry organic matter). The significance of the research results lies in the fact that the use of winemaking waste as a substrate will allow a third increase in biogas output and power generation, and a reduction in the payback period of a 4,4 MW biogas plant using the green tariff to 6,5 years.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2021Publisher:ЗАО "Научно-техническая фирма "Энергопрогресс" One of the most effective and reliable ways to increase the efficiency of CHP is the organization of heating raw water in the condensers of cogeneration turbines with the simultaneous supply of circulating water through the main bundles. The temperature of raw water supplied to the chemical water treatment at most CHP plants should not exceed 30-40 °C. Fulfillment of this condition is not always possible, and it becomes necessary to analyze and adjust the operating modes of turbines, which provide the most effective heating of water in the built-in bundles. Such an analysis can be carried out quite simply on the basis of operational data and a mathematical model of the condenser developed at the Department of Heat Engineering and Hydraulics of VyatSU. In this paper, an analysis algorithm is considered based on the actual data obtained during the tests of the condenser of the PT-80-130 turbine unit in the mode of its operation according to the electrical schedule, conclusions are drawn from the analysis results. Один из наиболее надёжных способов повышения эффективности ТЭЦ -- организация подогрева сырой (подпиточной) воды в конденсаторах теплофикационных турбоустановок при одновременной подаче циркуляционной воды через основные пучки. Температура сырой воды, подаваемой в цех химводоочистки, на большинстве ТЭЦ не должна превышать 30 - 40\\оС. Выполнение данного условия не всегда возможно, и возникает необходимость анализа и корректировки режимов эксплуатации турбоустановок, обеспечивающих наиболее эффективный подогрев воды во встроенных пучках. Проведение такого анализа достаточно просто можно выполнить на основе эксплуатационных данных и математической модели конденсатора, разработанной на кафедре теплотехники и гидравлики ВятГУ. В данной работе рассмотрен алгоритм проведения анализа на основе фактических данных, полученных при испытаниях конденсатора турбоустановки ПТ-80-130 в режиме её работы по электрическому графику, сделаны выводы по результатам анализа.

Соблюдение температурного режима в допустимых пределах при сушке кормов позволяет сохранить в них питательные вещества, в том числе витамины. Сушка зерна или других кормовых средств – достаточно энергозатратный способ их заготовки. Использование геотермальной воды как источника тепла для сушки представляется достаточно эффективным в плане энергосбережения и снижения физических затрат. Высокая температура геотермальной воды (87-90°С), при прохождении по трубам, уложенным в полу при помощи бетонной стяжки, способствует прогреву и сушке растительной продукции. Высокий уровень температурного режима и нормативы качества термальной воды позволяют использовать ее при реализации способа сушки зерна и различных видов рассыпных комбикормов. Кроме того, применение термальной воды в качестве тепловой энергии напольного водяного теплого пола является одним из самых энерго-и ресурсосберегающих способов при сушке зерна и различных видов сочных кормов. Предлагаемый кондуктивный способ сушки зерна представлен по принципу соприкосновения сырья с нагретой поверхностью, при котором обычно наблюдаются большие расходы топлива, но в нашем случае тепловым агентом служит термальная вода, при котором энергетические затраты сводятся к минимуму. Использование предложенного способа предполагает применение различного вида ворошителей, что в свою очередь сопряжено с дополнительными энергетическими затратами. Наряду с этим, выявлена низкая производительность сушилки, связанная с невысокой температурой и неравномерного ее распределения по бетонному полу. В исследованиях статьи предлагаются результаты и эффективность применения способа сушки и приготовления разных кормовых средств с использованием тепловой энергии геотермальной воды напольного водяного отопления. Drying of feed products helps to remove moisture and prevents biochemical processes in plant cells that contribute to the destruction of proteins, fats and carbohydrates. Compliance with the temperature regime within acceptable limits when drying feed allows you to preserve nutrients in them, including vitamins. Drying grain or other feed products is a fairly energy–intensive way of harvesting them. The use of geothermal water as a heat source for drying seems to be quite effective in terms of energy saving and reducing physical costs. The high temperature of geothermal water (87-90°C), when passing through pipes laid in the floor with a concrete screed, contributes to the heating and drying of plant products. The high level of the temperature regime and the quality standards of thermal water allow it to be used in the implementation of the method of drying grain and various types of loose compound feeds. The proposed conductive method of drying grain is presented according to the principle of contact of raw materials with a heated surface, in which large fuel costs are usually observed, but in our case thermal water serves as a thermal agent, in which energy costs are minimized. The use of the proposed method involves the use of various types of agitators, which in turn involves additional energy costs. Along with this, the low productivity of the dryer was revealed, due to the low temperature and its uneven distribution on the concrete floor. In the research of the article, the results and effectiveness of the application of the method of drying and preparation of various feed products using the thermal energy of geothermal water of underfloor water heating are proposed.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2023Publisher:ООО Цифра The relevance of the topic is determined by the existing problems in the creation of new environmentally friendly technological processes to ensure the rational use of available renewable resources. Due to the rapid depletion of non-renewable resources, and subsequent pollution of the environment, people faced the question of reorganizing their activities and reducing the harmful effects by using waste resources to create a new type of fuel. The subject of the study is the subsequent utilization of wastewater in the production of liquid biofuel. Various methods of organizing wastewater disposal were examined and their main common disadvantages were characterized. It was established that when applying traditional mechanical and biological treatment methods, there is a necessity in additional treatment of wastewater from biogenic elements and in improvement of methods of treatment and utilization of their sludge. As a result of the research, it was concluded that the application of traditional mechanical and biological treatment methods necessitates additional treatment of wastewater from nutrients and improvement of treatment and disposal of sludge. As one of the most promising methods of additional treatment, it was proposed to use wastewater as a medium for cultivation of energy microalgae in closed-type photobioreactors with subsequent production of liquid biofuel of the third generation. Актуальность темы определяется наличием проблем в создании новых экологически безопасных технологических процессов для обеспечения рационального использования имеющихся возобновляемых ресурсов. Из-за быстрого истощения невозобновляемых ресурсов, в последующем загрязнении окружающей среды, перед человеком встал вопрос о реорганизации своей деятельности и уменьшения пагубных последствий путем применения отработанных ресурсов для создания нового вида топлива. Предметом исследования является последующее использование сточных вод в производстве жидкого биотоплива. Были рассмотрены различные методы организации водоотведения, охарактеризованы их основные общие недостатки. Выяснилось, что при применении традиционных механических и биологических методов очистки возникает необходимость в доочистке сточных вод от биогенных элементов и в усовершенствовании способов обработки и утилизации их осадков. В итоге исследования был сделан вывод, что при применении традиционных механических и биологических методов очистки возникает необходимость в доочистке сточных вод от биогенных элементов и в усовершенствовании способов обработки и утилизации их осадков. Как один из самых перспективных методов доочистки предложено использование сточных вод как среды для культивирования энергетических микроводорослей в фотобиореакторах закрытого типа с последующим производством жидкого биотоплива третьего поколения.

New principles for design of heat and mass transfer equipment in the version with a movable packing of heat exchange elements (fluidized bed packing "gas - liquid - solid body") placed in the packed bed were developed, which allows self-cleaning of the working surfaces and walls of the heat and mass transfer equipment HMT. This new solution, when working with outdoor air and solutions of absorbents, seems to be a fundamentally important condition for maintaining the working capacity of solar absorption systems. The new schemes of absorber with internal steam cooling allowing the improvement of the new scheme of the alternate refrigerating system were developed. Comparative analysis based on the methodology of the "Life Cycle Assessment" (LCA) showed that new, developed solar systems provide the considerable decrease in energy consumption, their use leads to the decrease of exhaustion of natural resources, influences less global climate change.
