Abstract
PURPOSE: To enable to economically treat the night soil with a small amount of dilution water, by treating the treating water after performing nitrification and denitrification treatment of ammoniacal nitrogen component in a forced concentration apparatus and using obtained high-concentration activated sludge for said nitrification and denitrification treatment.
CONSTITUTION: Nitrification and denitrification treatment of raw night soil, is performed in the mixing decomposition vessel 2 and residual ammoniacal N component is treated in the nitrification vessel 3 and the denitrification vessel 4 and furster, a high-concentration activated sludge is separated by the forced concentration apparatus such as centrifugal dehydrator through the reaeration vessel 5. A part of said sludge is supplied to the decomposition vessel 2 through the return sludge flow passage 7 and also, residual part of it is supplied to concentrating tank 15 via sludge adjusting tank 14 together with recovered sludge from the precipitation vessel 11 and then, supernatant liquid is returned to the dilution adjusting vessel 10. Further, the greater part of ammoniacal N component is removed by the circulation in the circulation passage 8. Treating water separated by the apparatus 6, is sent to the vessels 10, 12 and the coagulation precipitating vessel 12 and the whole quantity of the recovered sludge is sent to the vessel 10 through the sludge return passage 13. Accordingly, the treated water is diluted in the vessel 10 and clean water is obtained by treating with activated sludge, even if the treatment in the apparatus 6, is insufficient.
