摘要
FIELD: water supply; sewerage.SUBSTANCE: invention can be used in environmental protection during treatment of domestic and industrial waste water. Method is realized by preliminary preparation of biopreparation in nutrient medium with further introduction of waste water and biopreparation into aerotank. Nutrient medium for the EM-biopreparation is represented by active sludge from the aerobic and anaerobic zones of the aerotank in different reservoirs - reservoirs for aerobic stabilization of activated sludge with forced aeration and reservoirs for anaerobic stabilization of activated sludge without oxygen access for formation of two qualitatively different types of biomass. Ratio of EM-biopreparation and active sludge is 1:100, supply of stabilized active sludge into corresponding zones of aerotank is carried out on basis of 1 l of mixture of waste water and active sludge per 1 mraw waste water.EFFECT: invention provides intensification of operation of process scheme of biological treatment of waste water, increased biomass of microorganisms, reduced time of adaptation of biopreparation microorganisms to varying conditions of food sources, fusion of cenoses of biopreparation and activated sludge at stage of aging of working solution.1 cl, 1 dwg
