In recent years, the concept of sponge city has been applied in different places. There are also many experts on sponge cities who believe that to build a sponge city in the city, we need to improve and optimize the rainwater system. In this way, we can better explore the way to plan and design the stormwater system when conducting the construction of the sponge city. This paper will also analyze and study the characteristics and functions of rainwater system planning in the construction of sponge city, and also point out the difficulties of the city in the construction of sponge city. Nowadays, the city must make clear its optimization direction, methods and principles in the transformation of rainwater system, and the optimization and transformation of rainwater system can also improve the construction progress of sponge city faster. The optimization and application of rainwater system can lay a solid foundation for the construction of sponge city.

The object of the study is the water supply and sanitation system of an industrial enterprise. Currently, many enterprises do not use the treated industrial waste water in the water supply cycle. Therefore, the use of treated wastewater is of practical importance. The scheme of thermal treatment of waste water for obtaining pure condensate by evaporation is proposed. The main results of the study are the technical solution for the development of the enterprise's wastewater treatment complex. Pure condensate is obtained in an instant boiling evaporator. The research method is based on the calculation of energy costs in wastewater treatment for different types of waste water. The results of the study allow us to determine the optimal set of energy equipment for obtaining pure condensate and its further use. The specific practical significance lies in the development of a technical solution that helps the treatment of wastewater and the reduction of emissions into the water basin.

In recent years, with the rapid development of the rural economy, while the living standards of rural residents have been greatly improved, the environmental conditions in the rural areas are not optimistic, and water pollution is one of the most important ones. Therefore, in order to improve the rural ecological environment and promote the task of water pollution control, Shandong Province has issued “the Governance Action Plan of black and odor water in rural areas of Shandong Province”. This article mainly uses “ the Action Plan” as a guide to analyze the current situation of rural black water bodies in Shandong Province and the current problems and related countermeasures, and follow the “comprehensiveness, applicability, economy, long-term effectiveness and safety. According to the black and odorous water problems caused by natural, technological and human factors, we will adopt comprehensive methods such as water purification, dredging, source control and pollution interception[1]to promote the treatment of black and odorous water bodies in rural areas, solve outstanding water environment problems in rural areas, and speed up construction of beautiful and livable countryside.

The paper analyzes the system at higher education in the context of achieving the goals of sustainable development of modern society. From the point of view of a systemic approach, an attempt is made to identify and classify the factors that can measure the contribution of higher education institutions to achieving the Sustainable Development Goals at the regional level. These factors are correlated with the corresponding tasks, as well as possible problems that are posed by the present unstable situation, and hinder sustainable development of the society. The research uses system-wide methods of analysis and synthesis, generalization and analogy. The analysis of the tasks and problems presented in the article allows us to identify and investigate the cause-effect relationships between the factors that determine the achievement of the Sustainable Development Goals and the complexities that accompany this process, and also contributes to the holistic perception of the concept of sustainable development by university staff members and students. The results of the study can be used in event planning within the framework of implementing the strategies drawn up by universities in the context of the sustainable development paradigm.

At the present stage of the transition to sustainable development, when the share of a green economy in technologically advanced countries reaches one third of GDP, overcoming the structural crisis of the Russia is inseparable from reducing the technological gap and structural imbalances in the economy. These imbalances alienate Russia from ecologically and technologically advanced countries. Therefore, it is highly relevant to develop a methodology for assessing the structural convergence of the economy in the context of the transition to sustainable development, accompanied in developed countries by a new type of structural shift caused by the expansion of convergent technologies, the emergence of new principles of sectoral genesis and the formation of a green economy. The deepening of the divergent nature of Russian economy development was the result of a series of negative structural shifts that consolidated the dominance of extractive and resource-intensive industries, which threaten the final loss of technological identity, consolidation of the recessive trend and a lag in the transition to sustainable development. Therefore, today it is extremely important to formulate a methodology for assessing the structural convergence of Russian economy with technological and ecologically advanced countries, taking into account both quantitative and qualitative aspects.

The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

As an important type of disaster, urban waterlogging has become a great challenge for urban governance around the world, threatening people’s lives, health and safety and property safety. The United States, Britain, Japan, Singapore and other countries have accumulated rich experience in the prevention and control of urban waterlogging. Foreign countries have strengthened the prevention and control of urban waterlogging disasters mainly in terms of condensing concepts and awareness, improving laws and regulations, paying attention to planning and construction, using scientific and technological means, strengthening knowledge popularization, strengthening risk assessment and early warning, implementing project-driven and active participation of multiple subjects, and achieved certain results. It is of reference and enlightening significance. In terms of the current and future urban waterlogging prevention and control in China, we should continuously improve the concept and awareness of urban waterlogging prevention and control, scientifically and systematically plan and construct the city; comprehensively use various policies and scientific and technological effective means to improve the effectiveness of urban waterlogging prevention; pay attention to waterlogging Risk assessment and disaster early warning work to realize the advancement of waterlogging disaster governance; strengthen knowledge promotion, popularization and multi-subject participation, create a joint force in urban waterlogging prevention and governance, and promote the modernization of urban waterlogging management systems and capabilities.
