Zusammenfassung:The relevance of deep treatment of domestic wastewater from objects in non-sewer areas is considered. The analysis of existing treatment technologies and structures is given. A three-stage aerobic bioreactor with preliminary anaerobic wastewater treatment, which ensures a decrease in the content of various forms of nitrogen, BOD and suspended solids in the wastewater during the life of the bacteria attached to the brim and free-floating microorganisms is proposed. A methodology has been developed for calculating and designing a low-capacity installation for deep wastewater treatment, taking into account the laws of nitrification, denitrification and oxidation of organic pollutants according to the stages of treatment, taking into account the quality requirements for treated wastewater at the level of standards for discharge of effluents into fishery ponds.
