    Abstract. The issues of removal of organic pollutants and nitrogen compounds from wastewater on bio-filters are considered. Special attention is paid to these structures due to their wide distribution since the 1960s-1970s. It seems important to study the technology that makes it possible to achieve modern standards for the discharge of treated wastewater into reservoirs using bio-filters. A method of deep removal of nitrogen compounds and organic pollutants on bio-filters has been developed and tested, the most effective technological schemes for wastewater treatment have been analyzed, and the results of hydrochemical analysis of the resulting biomass have been presented. It has been established that a stable and maximum effect on nitrogen removal is achieved by using a technological scheme operating with the recirculation of nitrate water. The conducted studies of biofilters operating in the denitrification-nitrification mode have shown the expediency of using these facilities for deep wastewater treatment with the provision of regulatory indicators for discharge into a reservoir of fishery significance.
