摘要

Method of deep biological treatment of sewage containing faeces with sharply varying with time expenditure and the composition comprising filtering the water to separate large solids, settling to remove from waste sand water and the coagulated impurities, the averaging flow rate of wastewater treatment community wastewater aquatic organisms from bacteria to zooplankton for water purification from dissolved organics and nutrients and subsequent decontamination effluents to remove pathogenic Microorganisms, characterized in that mnogoilovoy system of biological purification of sewage all sludge systems advantageously employ biocenosis attached to Ershovoy nozzle microorganisms without the use of secondary clarifiers, thin-layer settlers-desilters are utilized only for thickening sludge from Ershovoy nozzle regeneration stages tertiary sewage treatment and during the commissioning, the circulation return flow of treated water - the source of nitrites and nitrates is organized of the steps completed Ia process of nitrification of ammonium nitrogen waste water effluent inlet to the bioreactor; at all levels of biological wastewater treatment processes nitridenitrifikatsii activated the air as an oxygen source and means for mass transfer between attached to Ershovoy nozzle hydrobionts and cleaned waste water feed it under Ershov nozzle, and at step tertiary sewage treatment air supply is made through the airlift niche during wastewater treatment and for the regeneration Ershov nozzle ethane ruff aftertreatment of n
