A high level of energy-efficient operation of structures can be achieved through automated life-support systems using secondary energy resources. Analysis of thermal emissions in residential buildings allows us to conclude that the most promising for this purpose are wastewater. The process of utilizing the heat of the used water resources entering the sewerage network can be carried out in two types of evaporative heat exchangers: surface and submerged.The increased area and increased heat transfer efficiency create the conditions for the preferable choice of a submersible type storage wastewater-freon heat exchanger. The design of the case of devices of this type allows to obtain a model range by the step change in its diameter. The calculations carried out for the case diameters of 300, 400, 500 mm have shown that at various water flows the best heat exchange parameters are achieved at a diameter of 300 mm, both under conditions of forced and natural convection.

It is established that the reclamation of technogenic disturbed landscapes is accelerated by the use of a complex of agro technical measures, including the selection of species of perennial grasses and the optimization of mineral nutrition. Studies carried out in the Yamburg gas condensate field in areas lacking of the biologically active layer have developed elements for soil and vegetation reclamation.

The possibility of spreading technology for capturing carbon dioxide from the flue gases of industrial enterprises as well as the utilization of sulfur dioxide is considered. A comparison is made between the physicochemical properties of these gases. Based on the experimental data obtained from the capture of sulfur dioxide, it is concluded that this technology can be successfully applied for the utilization of sulfur dioxide from gas emissions from industrial enterprises.

Studies have been carried out to create a lanthanum-containing ceramic material that can be used to purify water from fluoride ions. A composition was developed for the preparation of a ceramic material, the physico-mechanical characteristics of its samples were determined, and their binding capacity to fluoride ions was investigated. There was researched environmental safety of a material. It is proved that when 6% by weight of lanthanum carbonate is added to the charge, an environmentally safe material for cleaning aqueous systems with a fluoride ion content of up to 10 mg/l can be obtained. It has been established that this material can be used with sufficient efficiency to purify water from phosphate ions.

The data of eleven-year monitoring of soil and subsoil contamination by kerosene, heavy metals, formaldehyde and nitrates on the territory of the aviation-missile cluster are presented. The adjusted index of total contamination with priority contaminants of soils and subsoil of various functional zones of the cluster (aviation-missile, industrial, residential-transport, recreational) have been calculated. Using the rank correlation coefficient of Spearman, a relationship was established between the content of priority contaminants in soil and subsoil. On the basis of the correlation analysis, the choice of kerosene as a marker compound for soil and subsoil contamination of air-missile clusters is justified. A piezo sensor was developed for the rapid analysis of kerosene in soil and subsoils in "on-site" mode without sampling and sample preparation. Optimization of ecological monitoring of soils and subsoil with the application of a test method for determining kerosene in the territories of aviation-missile clusters is proposed.

In the large urban urbanized areas, which primarily include the land of Moscow, is developing specific soil and subsoil - urbanozem, the degree of man-made pollution of them by heavy metals, benz-(a)-pyrene and petroleum products is determined by many factors. The author 's estimation of the annual variability of the concentrations of mobile forms of heavy metals, benz-(a)-pyrene and petroleum products in soils of Moscow, based on analysis in 2015 and 2016 is presented. 90 samples at 30 monitoring sites. The object of the author's observation was the soil cover of the city as a whole and some of its natural and technogenic transformed species, as well as the soil cover, which is moved in the process of urban development.

The possibilities of using unmanned aerial vehicles for visual inspection of waste disposal facilities, including closed objects, are considered. Examples of the results of processing aerial photographs for assessing the achievement of design elevation marks of disposal sites, the state of the reclaimed surface of objects, and the identification of negative impacts on adjacent territories are presented. The experience of applying aerial survey results to assess the state of waste disposal facilities during the aftercare period, to obtain objective and evident information about changes in the components of the environment in the adjacent territories.

A brief review of the ecological state of artificial water bodies is presented on the example of the Voronezh and Matyr reservoirs located in the basin of the river. Voronezh. Ecological-geochemical interrelation of water areas of reservoirs and adjacent territories with anthropogenic sources of pollution located on them is shown. The basis of the research is the bioindication method for the communities of phytoplankton and microphytobenthos. Changes in the sanitary and biological quality of the waters have been studied in the reservoirs, which are related, in particular, to the effect of anomalously high summer air temperatures in 2010–2012 and in subsequent years, and for the Matyr reservoir against this background, an estimate of the effectiveness of the use of algobiotechnology is given.

The sources of contamination with heptyl (asymmetric dimethylhydrazine (NDMG)) associated with the operation of rocket and space technology have been identified and analyzed.

In the process of work, the advantages and disadvantages of all the methods considered, as well as the features of their application, are revealed. The basic principles of choosing the most suitable methods in each particular situation are proposed. In general, a reasonable combination of all existing methods is recommended at different stages of soil reclamation.

In the article, the environmental efficiency of the system approach to the environmental policy implementation has been illustrated by the example of the State Atomic Energy Corporation ROSATOM. The system approach has proved to be the main feature of the environmental policy of the State Corporation. ROSATOM’s system approach consists of four principles: planning, implementation, reporting, and monitoring and continuous improvement of the State Corporation’s environmental performance, based on these principles. The environmental effectiveness of the system approach to the environmental policy of the Corporation has been shown based on the specific indicators of harmful substances emission, discharges to water bodies and waste generation abatement, as well as on the indicators of the effectiveness of the liquidation of hazardous nuclear facilities and rehabilitation of radiation contaminated territories.

In this article examines the interrelation between the processes of industrialization and urbanization in terms of their impact on the quality of life in cities. The modern city is largely the result of the accelerated development of industry in the XIX - early XX centuries, however, the transition to the postindustrial phase of the development of society, which begins in the second half of the XX century, leads to deindustrialization of urban development. One of the trends of modern urban planning is the reconstruction of industrial zones which is carried out in the form of their adaptive reuse, which avoids many of the costs associated with their radical restructuring, although such a path is not always possible. According to opinions of the authors, the appeal to the idea of adaptive reuse becomes one of the means of revitalizing the urban landscape and, as a result, urban life.
