The purification of industrial and surface wastewater from heavy metal ions (HMI) to requirements for the discharge of treated wastewater into natural waters is one of the most complicated environmental and technological problems. For the deep purification of waste water from the HMI, the use of cheap sorbents obtained from production waste is the most promising. One of the many-tonnage wastes of technology of inorganic substances is the sludge formed in the production of soda by the ammonia Solvay, s method. Currently, sludge is stored in sludge accumulators and is a long-term source of pollution of environmental objects. Scientific developments in the utilization of slimes with the production of building materials, etc., have not found wide practical use, which is due to the heterogeneity of the granulometric and chemical composition of the waste. Carried out X-ray phase analysis and studies of the physicochemical and chemical properties of waste samples showed that its main components are calcium carbonate (calcite) and calcium hydroxide (portlandite). It is known that the natural mineral limestone efficiently extracts HMI from aqueous solutions with the formation of less soluble basic salts, carbonates, and hydroxy carbonates of HM. It has been established that sludge samples have high sorption activity when copper(II) and zinc ions are extracted from low concentrated solutions (sorption capacity for copper ions is 35.0 mg/g, sorption capacity for zinc ions is 40 mg/g). To increase the operational properties, a method has been developed for the production of a modified granular sorbent based on the sludge of soda production, consisting in treating with sodium silicate. The effect of a dose of sodium silicate in the sorbent composition on the mechanical strength and sorption properties of the obtained samples was studied. It has been established that the introduction of 8,6% SiO2 into the sludge leads to an increase in the mechanical strength by 50–80%, and does not have a significant effect on the sorption activity of the material. The kinetic and sorption regularities of extraction of copper(II) ions and zinc on modified sorbents are revealed. Based on the analysis of the adsorption isotherms obtained, the adsorption equilibrium constants and maximum adsorption values (Amax (Cu2+) = 50.8 mg/g; Amax (Zn2+) = 97.1 mg/g) were determined. Obtained sorption materials can be recommended for wastewater treatment from HMI.

The inclusion of historical ideas in the discourse of philosophical knowledge of the universal unity of thought and being at the turn of the 18th-19th centuries was the necessary and only possible way to overcome abstraction in assuming the subjectivity of this unity. The first step in solving this problem is associated with the name Montesquieu, which determined on the part of Hegel the assessment of his work as the realization of a truly philosophical point of view, which resulted in an understanding of society as a living whole. The historical idea in Montesquieus teaching reached a level of concreteness due to the synthesis of the idea of spirit and the idea of freedom. However, she could not get a theoretical justification given the level of philosophical thinking in the middle of the 18th century. The concept of history (Geschichte) finds concrete in theoretical presentation only in the late Hegelian philosophy, thanks to the achieved method of understanding the universal unity of thought and being as a substance-subject of the spirit. Включение идеи исторического вдискурс философского познания всеобщего единства мышления ибытия нарубеже XVIIIXIXвв. было необходимым иединственно возможным способом преодолеть абстрактность вполагании субъективности этого единства. Первый шаг врешении этой задачи связан сименем Монтескье, что определило состороны Гегеля оценку его творчества как реализацию истинно философской точки зрения, имевшей результатом понимание общества как живой целостности. Идея исторического вучении Монтескье достигла уровня конкретности благодаря синтезу идеи духа иидеи свободы. Однако она немогла получить теоретического обоснования сучетом уровня философского мышления середины XVIIIстолетия. Понятие истории (Geschichte) обретает конкретность втеоретическом изложении лишь впоздней философии Гегеля, благодаря достигнутому методу понимания всеобщего единства мышления ибытия как субстанции-субъекта духа ВЕСТНИК РУССКОЙ ХРИСТИАНСКОЙ ГУМАНИТАРНОЙ АКАДЕМИИ, Выпуск 20 (4) 2020

The relevance of the article is due to the fact that in the modern education of the Russian Fed-eration, including preschool, a radical reform is being carried out, new educational and professional stand-ards are being introduced. This leads to the need for serious changes at the level of professional activities by teachers of preschool educational institutions. All this requires the identification of determinants that cause negative trends in the educational space of preschool educational institutions, for their localization, overcoming and timely prevention. The purpose of the study was to identify the specifics of professional self-realization of teachers of preschool educational institutions, the definition of psychological resources that provide its different levels of formation. Актуальность статьи обусловлена тем, что в современном образовании Российской Федерации, в том числе дошкольном, осуществляется кардинальное реформирование, вводятся новые образовательные и профессиональные стандарты. Это приводит к необходимости серьезных изменений на уровне осуществления профессиональной деятельности педагогическими работниками дошкольных образовательных учреждений (ДОУ). Все это требует выявления детерминант, вызывающих негативные тенденции в образовательном пространстве ДОУ, для их локализации, преодоления и своевременной профилактики. Целью исследования стало выявление специфики профессиональной самореализации педагогических работников ДОУ, определение психологических ресурсов, обеспечивающих ее разные уровни сформированности.

Studying the problem of diagnosing high-voltage lines is the goal of this research. The high accident rate of overhead lines due to icing and current overloads makes this problem important. Current overloads during distributed power generation lead to overheating of the lines. The goal of the research is achieved due to the fact, that the article notes the relationship between icing and overloads. The necessity of joint solution of these problems and the development of the concept of a multifunctional measuring system is proved. For this, an analysis of the main parameters that determine the mode of operation of overhead lines is carried out. Technical solutions for the measurement of these quantities are considered. The detection of ice formation by comparing the values of dew points and desublimation is described. The calculation of the limiting current load taking into account weather conditions is given. The amount of sagging wires is selected as a universal characteristic of the state of the line. A significant result of the study is the optical method of icing control. This method consists in measuring the coordinates of the line wires through a weatherproof CCTV-camera. To do this, optical tags and a temperature sensor are placed on the wires. The optimal architecture of the measuring system for assessing the climatic impact is given. The significance of the results is that a multifunctional and high-precision system without expensive load sensors is proposed. The conclusion about the importance of the results for building a smart grid is made.
