Abstract: Traditional biological wastewater treatment systems are unable to completely remove biogenic substances due to the lack of the necessary amount of substrate, the specifics of the technological scheme, and only the involvement of raw sediment and partially excess sludge in the biological process (continued aeration) can solve the specified problem. The use of psychrophilic anaerobic displacement reactors with an expanded layer of sludge (EGSB-reactors) and subsequent stages of biological treatment will allow to achieve of deep purification of wastewater from carbon, nitrogen and phosphorus in purified water and significantly reduce the volume of extracted sediments and their morphology. Therefore, the aim of our work was the development of a method of municipal wastewater treatment using facilities with a lower material capacity, with lower energy consumption for deep biological removal of carbon, nitrogen and phosphorus compounds. Systematic investigations of the technologies, reactor designs, and processes for anaerobic treatment of low-concentration effluents in psychrophilic conditions calculations were carried out at the Kaniv wastewater treatment plant. Based on this, a model-concept of treatment facilities was developed. Design work was completed for the reconstruction of the Kaniv wastewater treatment plant, where two EGSB psychrophilic reactors, converted from the existing two-tier clarifiers, were put into operation.
