The effect of pulsed EMF with a pulse repetition frequency of 16 Hz on the decomposition of organic compounds in wastewater in the presence of activated sludge microorganisms has been studied. It is shown that aerobic purification of a mixture of wastewater and activated sludge in the presence of a continuous pulsed electromagnetic field with a frequency of 16 Hz and a magnetic induction of no more than 0.5 μT accelerates the process of ammonification by 25 %, nitrification and denitrification by 15 %, reduction of COD by approximately 20 %.The intensity of the increase in the biomass of activated sludge and the rate of its deposition were noted.

The possibility of using energy and resource-saving power plants of cogeneration type with steam injection into the flow part with deep utilization of high-potential and low-potential heat of the gas-steam mixture in systems for degassing municipal solid waste is investigated. The use of a combined technology of absorption and adsorption purification of landfill gas is proposed. The conclusion is made about the effectiveness of using landfill gas as an energy carrier in a combined contact-type bioenergetic installation with a heat recovery heat exchanger, which will save the national wealth of the country and at the same time solve the problems of modern megacities associated with reducing the negative impact of MSW landfills on the environment.

The world experience of carbon capture, use and storage (CCUS) projects in the world was presented and analyzed – the entire CCUS technological chain was shown, including a description of its elements, and the areas of CO2 use in different areas of global industry are given. The prerequisites and prospects for the formation of CUS in Russia are presented. A qualitative and quantitative assessment of the underground space of the regions of Russia for the disposal of carbon dioxide is given. It is worth noting that the concentration of large enterprises of the metallurgical industry, oil refining, chemical industry and oil and gas fields allows you to create a special CCUS cluster and reduce emissions of pollutants, as well as effectively use the captured CO2 in various industries of Russia.

The results of many years of research on the assessment of the impact on the air basin of the technogenic system – tailings dumps of highly toxic waste using methods of mathematical statistics is presented. The research was carried out within the boundaries of the Dalnegorsky Ore District of the Primorsky Territory of the Far Eastern Federal District (Far Eastern Federal District). It has been established that the main pollutant is dust containing elevated concentrations of heavy metal compounds, which is removed from the surface of tailings dumps by air flows. The spatial and temporal patterns of the distribution of the pollutants in the atmospheric air are revealed. It has been experimentally proved that contamination of the air basin with heavy metal compounds, sulfate ion aerosols, and dust is extremely high. The ways of reducing its negative impact on the air basin are proposed.

It was found that dust of electrostatic precipitators supplied to the sintering furnace from the hot end precipitates little on the sintered material of the raw charge of alumina production of JSC "RUSAL Achinsk", increases the dust turnover and dust release of solid pollutants from the furnace into the atmosphere. In order to increase efficiency of purification of atmospheric air from fine dust of electric precipitators it is proposed to remove it from dust circulation of the sintering furnace and dispose of it separately in technology of road mixture when laying the base of road pavements. The introduction of this technology provides a reduction in atmospheric emissions from 18.965 to 5.859 g/s, a reduction in coal consumption by 1.39 kg of conventional fuel for the production of 1 ton of sinter and savings of coal fuel by 8350 tons per year.

The article analyzes data on the use of an integral indicator of the concentration of organohalogen compounds (OHC) to control the quality of industrial and natural waters. The results of studies of natural waters of lakes in the Arkhangelsk region were presented. Several "conventionally clean" lakes that have never been subjected to technogenic impact, as well as those that have previously been subjected to direct anthropogenic impact, were studied. It was shown that the OHC rate of natural waters was not an indicator of water pollution unlike with industrial wastewater. It was emphasized that this indicator of natural water determines the background concentration of organohalogen compounds, which was not a constant value, since it was caused by many biotic and abiotic factors.

The features of the installation of booms on rivers were given, taking into account the fact that rivers form periodic ancones, which causes an uneven distribution of river flow along the bed. The article proposes the most optimal way to install booms on rivers based on a series of experiments. Detailed calculations were presented to determine the elongation of booms when they are installed on rivers. Flow loads were determined and presented, as well as their distribution along the floating boom outline. Variants of installation of booms on ancones and straight sections of rivers were considered. The optimal bank for the installation of booms was identified, taking into account the conditions for ensuring the best holding capacity of booms, as well as the convenience of collecting oil and other factors.

Surface layers of apatite-nepheline ores mill tailings were analyzed. During the snowless period in2022, the dynamics of PM2.5 and PM10 dust concentrations in the atmosphere air of Apatity, Murmansk Region, was studied. Excess of MAC of sparingly solubles were detected. Mineralogical analysis of tailings and dust samples were carried out, the presence of nepheline and sodalite was detected, which confirms the involvement of tailing dumps of apatite-nepheline processing plants in air pollution. It was concluded that, in addition to the tailing dump, transport and other industrial sites have a significant impact on the atmosphere air, since airborne dust samples contain small particles of oxidized iron, plastic, glass, and metal scale. The role of green areas in buffer zones and within the boundaries of urban development was emphasized.

The efficiency of integrated gas emissions treatment in thermal waste treatment units from dust particles and fossil sour traces of SO2, HCl and HF, as well as volatile organic compounds (VOCs) and dioxins at 300–400 °C of the gas mixture with a ceramic gas filter with aluminosilicate fibers added with catalytic MgCr2O4. The efficiency of sorption purification of tail gases from SO2, HCl and HF during the test period was 79–90 %, which depended on the supply of slaked lime to the catalytic filter to prevent catalyst deactivation. Thermal mode of chemical refining (300–400 °C) provided effective catalytic purification from VOCs, CO, and dioxins in combination with the chemisorption recapture of catalytic poisons and dust, preventing neither sorbent degradation nor damage to the catalyst.
