PROCESSING METHOD AND PROCESSING APPARATUS OF AMMONIA-CONTAINING WASTE WATER

摘要

PROBLEM TO BE SOLVED: To provide a processing method and a processing apparatus of ammonia-containing waste water capable of processing waste water containing ammonia nitrogen to stably obtain good treated water.SOLUTION: Nitrification bacteria are cultivated in the presence of a carrier using a liquid containing ammonia nitrogen of 200 mg/L or more and 1,000 mg/L or less, stuck to the carrier and propagated to form an immobilization carrier. A processing method of ammonia-containing waste water processes waste water in a waste water processing tank housing the immobilization carrier at a nitrification rate of 1.0 kg-N/m/day or more and 2.0 kg-N/m/day or less.SELECTED DRAWING: Figure 3
