Abstract
PURPOSE: To attain the removal of N component and the following sludge in waste water in a high degree without using chemicals, by contacting nitrification regenerating liquid of cation exchanger adsorbed NH4 +-N in the waste water with the sludge generated in the waste water treating process and promoting denitrification reaction.
CONSTITUTION: Waste water is introduced 2 into the settling pond 1 and supernatant liquid separated from the settling coarse precipitate 22, is sent to the adsorption vessel 5. Then, NH4 +-N in the waste water is removed by the ion exchange ability of zeolite in the vessel 5 and the primay treating water is sent to the aeration vessel 14. The activated sludge 23 having COD oxidizing ability, is flowed in the vessel 14 from the settling pond 18 through the ducts 20, 10. Also, the vessel 14 is maintained at an aerobic atmosphere by minute air bubbles containing O2 and organic matter in the waste water is decomposed by oxydation by the sludge 23. Next, said treating water is flowed in the pond 18 with the sludge 23 and the sludge in the treating water is settled and then, the sludge is separated from the supernatant liquid. On the one hand, O2 is supplied to the vessel 5 through the duct 9 and the sludge containing nitrification bacteria, is supplied to the precipitation vessel 15 and then, the zeolite is regenerated.
