PURPOSE: A method for operation of an anaerobic ammonia oxidization tank is provided to reduce culture period of an oxidization bacteria without degrading performance of anaerobic ammonia oxidation in one side.;CONSTITUTION: A method for operation of an anaerobic ammonia oxidization tank is conducted by denitrification of ammonia and nitrite by ammonium-oxidizing bacteria and oxidization of anaerobic ammonia. A part of the anaerobic ammonia is collected from an anaerobic ammonia oxidation tank of one side and injected into an anaerobic ammonia oxidation tank of the other side for operation. The anaerobic ammonium-oxidizing bacteria are microorganism-immobilized bacteria which are fixed by an immobilizing material. The collected immobilized material is mixed with a sludge, mixed with a gelation material and is panoptically fixed.;COPYRIGHT KIPO 2013
