Abstract

PURPOSE: To treat the septic tank sludge satisfactorily at a night soil treating equipment provided with a mixing and decomposing tank, by adjusting the ratio of amount of organic carbon and amount of nitrogen contained in the liquid of septic tank sludge to the ratio of them contained in the raw night soil.
CONSTITUTION: It is contrived to stabilize the amount of sludge of home use septic tank at receiving tank 14, and the sludge is stocked in storage tank 16 after the larger rubbish is removed by pretreating unit 15. Then, the sludge is separated into liquid and cake by solid-liquid separating unit 17. Then, the ratio of amounts of organic carbon and nitrogen contained in the liquid is adjusted so that the ratio may resemble to that of raw night soil. After the above mentioned adjustment is performed, the liquid is supplied to storage tank 3 of night soil treating equipment A provided with mixing and decomposing tank 4 and the cake is supplied to post- treating facility 18, and they are treated independently.
