Abstract
PURPOSE: To purity high concn. waste water efficiently in a short date by introducing said waste liquid into the 1st nitrification tank provided with an aeration installation having large oxygen supply capacity, performing nitrification treatment there thence introducing the same to the 2nd nitrification tank and performing nitrification treatment.
CONSTITUTION: Raw liquid 11 such as night soil is introduced in an undiluted state from a line 1 into the 1st nitrification tank 2, where 70W90% of NH4-N and org. nitrogen in the raw liquid are removed. At this time, an aerator 9 of oxygen supply capacity larger than that of an ordinary air diffuser tube is adapted in said tank 2 to supply a large amount of air 7. Thence, the treated liquid 12 out from the tank 2 is introduced through a line 13 into the 1st denitrification tank 14, after which it is introduced through a line 15 into the 2nd nitrification tank 3, where the residual org. nitrogen or the like are thoroughly removed by the aeration or air 8. The treated liquid 16 is introduced through a line 17 into the 2nd denitrification tank 18, after which it is suppied into a separating tank, where it is separated to supernatant and sludge. The treated water 10 is released through a line 19 to the outside of the system.
