    Abstract. Methods for the simulation of wastewater treatment processes at bio-filters are considered. The problems of removal of nitrogen compounds from wastewater at wastewater treatment plants of small capacity are analyzed. Since most of wastewater treatment plants of small capacity have bio-filters in their structure, it is the plants which a special attention is paid. The technique of thorough removal of nitrogen compounds at bio-filters is developed and tested, laboratory studies of various technological schemes of denitrification and nitrification are conducted. The conducted studies show the reasonability of using bio-filters for integrated treatment of domestic sewage for nitrogen compounds. Based on the results of the work, it can be concluded that the studies of the denitrification-nitrification system using bio-filters have shown the feasibility of its use for integrated treatment of wastewater for nitrogen compounds with the provision of regulatory indicators for discharge into the reservoir of fishery use. The results of sanitary - chemical analyzes and studies of the formed biomass are given. Based on the data obtained, the laboratory models for hydraulic modeling and simulation of denitrification-nitrification processes at bio-filters have been developed. The mathematical model is modified; for calculating the height of the bio-filters, specific mathematical dependences for the studied feed material are received. The modified mathematical model, which can be used for calculation of the height of biological filters loaded with the planar cylindrical material, is proposed.
    Key words: wastewater treatment, bio-filter, ammonium nitrogen, bio-film, denitrification-nitrification, modeling, hydraulic model, feed material.
