“…Agriculture as an economic activity is based on meeting the needs of the population for fresh and nutritious food, but is also one of the sources of pollution of the components of the environment [1][2][3][4][5][6][7]. At present, the negative impact of agricultural production on the environment, one of which is untreated wastewater [8][9][10][11][12][13][14][15][16][17], is advancing. Wastewater carries dangerous chemical compounds, pathogenic microorganisms, biogens included in fertilizers.…”

The article presents research on creation and implementation of a utility model for wastewater treatment plant (bunded filtration fields) in order to reduce the content of pollutants in water coming from the wastewater of a dairy processing plant. After analysing data on actual concentrations of pollutants in the wastewater treatment plant (bunded filtration fields), flow rates, and species composition of riparian vegetation, it was proposed to develop and implement a biological method for wastewater post-treatment using higher aquatic vegetation. For this purpose a utility model prototype of a floating bio-platform was produced, the size and number of structures were determined. The design of the wastewater treatment utility model includes two units: a structural unit and a vegetation unit. The constructive block included: a frame frame, composite masonry mesh, Equality Mark vapour barrier, and polyamide (braided) cord. The plant block is an artificially created phytocoenosis consisting of grass and turf and additionally higher aquatic plants. The design of the floating bioplata model was placed along the mirror of the reservoir in a line behind each other. When ready, several bioplats were connected together and transported through the water to their installation sites. For the conditions of the forest-steppe zone of the Trans-Ural region the assortment of aboriginal plants was selected and the method of their fixation and cultivation on the water surface was developed. The necessary area of covering of a water body by a bioplate for a decrease in the content of polluting substances in the future is calculated. The developed technology can be applied in any climatic zone with an assortment of higher aquatic vegetation characteristic of the area.

“…Recently, methods based on the use of natural processes occurring in landscape and water ecosystems have become widespread -the creation of artificial swamp ecosystems ("constructed wetlands"). "Constructed wetlands" are characterized by reliability and efficiency, do not require electricity and chemical reagents [12][13][14][15]. Pollutants are removed from the water through mechanical filtration and biochemical conversion; microorganisms are the main component of the wetland environment [16].…”

The problem of mining enterprises wastewater treatment has not lost its relevance over the past decades. The paper presents the results of laboratory studies on the nitrogen group compounds removal from the wastewater of an Arctic iron ore enterprise using various sorbents: zeolite, sishtof, thermovermiculite. The prospects of using geochemical barriers made of zeolite and vermiculite for the enterprise wastewater treatment are shown. The possibility of using spent vermiculite enriched with nitrogen as a prolonged action fertilizer as part of remediation measures was proposed.

“…Engineering and organizational measures to prevent pollution of drainage water with nitrogen compounds. At the same time, for example, the large mining enterprises in Russia and Sweden implement a biological treatment method in practice with an efficiency of about 90% [4][5][6][7][8], due to the need to treat significant amounts of quarry water (about 5-10 million cubic meters annually) that in practice does not allow to use other methods.…”

The nitrogen compounds, namely ammonium, nitrite and nitrate nitrogen, are the main substances polluting the quarry and drainage waters of mining enterprises that use the ammonium nitrate-based explosives for drilling-and-blasting rock mass preparation. In accordance with the legislation, such waters are subject to treatment prior to discharge into the water bodies. At the mining enterprises, the promising treatment method is the treated water conditioning in the flooded abandoned open-pit mines, during which the natural microbiological nitrification of ammonium and nitrite nitrogen contained in the quarry drainage waters is performed with an efficiency of more than 95%. The article discusses the influence of natural climatic and hydrodynamic factors on the nitrification process according to the results of a purification process study that has been performed since 2014 until the present time at a large mining enterprise. The relevant conclusions and recommendations are given.
