METHOD OF LAUNCHING BIOLOGICAL TREATMENT PLANTS Russian patent published in 2012 - IPC C02F3/34 

FIELD: chemistry.

SUBSTANCE: method of launching biological treatment plants involves feeding waste water into an aeration tank and biocenosis culturing in aeration conditions. Biocenosis culturing is carried out with continuous aeration for 36-48 hours with 0.5-1.0 m³/h of air per 1 m³ of the aeration tank of the portion of clarified household wastes with addition of biologically active nitrogen and phosphorus compounds BOD₅:N:P=100:1:0.5. Adaptogen is simultaneously added with gradual growing, in 36-48 hours, in the wastes being treated of a given concentration of the reference component contained in adaptogen from 0 to 5*10⁴ maximum allowable concentration (MAC).

EFFECT: invention provides faster launching of biological treatment plants, cuts the time for growing biocenosis; treatment of clarified household wastes begins after 5 days.
