Abstract: An organic wastewater treatment apparatus biologically treats organic wastewater containing nitrogen using a treatment tank storing activated sludge. A top-bottom partition member divides the treatment tank in into an upper space and a lower space. A plurality of anoxic tanks are formed in the lower space, while a plurality of aerobic tanks, each of which having an immersion-type membrane separation device, are formed in the upper space. A raw water supply path divides and supplies the organic wastewater to each anoxic tank. A plurality of denitrifying liquid transfer paths repeatedly transfers the activated sludge from the anoxic tanks to the aerobic tanks, while a plurality of nitrifying liquid transfer paths repeatedly transfer the activated sludge from the aerobic tanks to the anoxic tanks, whereby the activated sludge is circulated throughout the treatment tank.
