In this paper, the authors analyze the quality of the groundwater in the north-western region of Ukraine and propose the reassessment of a number of retrofit technologies for their comprehensive treatment. The authors argue that the underground water is a multi-component system. The authors propose a set of biological, physical and chemical methods of water treatment for a synergistic effect.The authors suggest reducing the number of consecutive water treatment units and using an advanced technology (activation of biological and physicochemical processes in a constant magnetic field). Another suggestion is the application of a set of technologies integrated into traditional methods of biological treatment. The authors also propose a consistent process of water treatment, so that the sub-processes within it were able to activate each other at each subsequent stage to achieve a synergistic effect. Degradation of organic iron requires a biologically active environment. The underlying technology can be transformed into more sophisticated process patterns depending on the quality of water exposed to treatment.

Introduction. Neutralization methods (including composting) are widely used in the technologies of chemical and biothermal oxidation of organic matter. A promising method of waste management is their biothermal composting using controlled gas flows. The methods of process intensification are described: the introduction of inoculating additives, increasing the homogeneity of the mixture, recycling of composts, natural and forced low-pressure and high-pressure aeration, and several others. One example of the implementation of these technologies is the disposal of oil-contaminated soils. Materials and methods. The description of the implemented complexes of biothermal composting of oil-contaminated soils: functional zoning, design solutions. The main functional zones are shown: input control section, intermediate placement area, continuous forced aeration zone (inoculation), periodic forced aeration zone (stacked cavalier biodegradation), and natural aeration zone without mixing (ripening zone). The main element of the complex is the combined aeration system (forced from blower devices and natural mechanical mixing). The expediency of using high-pressure forced aeration to intensify the composting process is shown. Results. The developed mode of operation of the aeration system of the composted mass is described: the initial process of incomplete oxidation of organic matter in stacks of inoculation with a constant air flow and the final decomposition of organic matter with a periodic air flow. The constructive design of the high-pressure forced aeration system used to intensify the composting process is given. Aerobic biothermal composting is performed in aerated piles, which are formed on sites with a waterproof coating. Aeration, necessary to accelerate the decomposition of organic matter in the composts, is carried out in natural (mixing with a ladle) and artificial (purging) conditions. For purging use a system of perforated pipes and blower station. Describes measures to protect pipelines (ducts) from aggressive environmental exposure and increase their service life, to ensure the efficiency of the aeration system in an emergency. Conclusions. The possibility of practical implementation of gas flow control technology in the design, construction and operation of biothermal treatment of waste is shown. The implementation of the projects described in the article showed the need to create a generalized mathematical model that would describe in general terms the behavior of gas flows in heterophase wastes.
