<p><P>PROBLEM TO BE SOLVED: To provide an operation method of an anaerobic ammonia oxidation tank which can shorten the acclimation period of anaerobic ammonia oxidation bacteria whose growth rate is slow, dispenses with installation of a culture plant, and prevents the performance deterioration of one anaerobic ammonia oxidation tank from which the anaerobic ammonia oxidation bacteria are pulled out. <P>SOLUTION: From an acclimation-completed tank 10 having microorganism immobilized material 14A where the anaerobic ammonia oxidation bacteria have been acclimated, a part of the microorganism immobilized material 14A is pulled out. The pulled-out microorganism immobilized material 14A is introduced into an unacclimation tank 12, where acclimation is performed hereafter, to start up the unacclimation tank 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
