Abstract

PURPOSE: To effectively perform the biological treatment and to make the aftertreatment easy, by separating solid from liquid and diluting at a low rate of dilution or as it is and then, performing the flocculation precipitation treatment by adding inorganic or organic flocculant after performing aerobic biological treatment of night soil after removing solid matters.
CONSTITUTION: Night soil received in the receiver 2 through the sand settling vessel 1, is sent to the rotary screen 4 by the crushing pump 3 and is stored in the night soil storage tank 15 after removing foreign matters. Said night soil is introduced into the biological treating vessel 17 having the treating rooms 17aWe. The circulation passage 19 provided with the circulation pump 18, is provided with the rooms 17aWc and pressurized air is sent to the passage 19 from the injector 21. Further, temperature of the night soil is controlled at a suitable temperature by the heat exchanger 22. Anaerobic decomposition is promoted by ruturning from the room 17d to the room 17 a and a greater part of generated nitrous acid and nitric acid, is reduced to N2 gas. Next, separated liquid is diluted at a low rate of dilution after separating solid from liquid by the centrifugal separator 25 and inorganic or organic flocculant is added and then, residual BOD, COD, SS, coloring component and phosphor, etc., are removed through the reaction vessel 33 and the settling vessel 34.
