Manufacturing Process of Activated Sludge for Partial Nitrification of Ammonium-ion Compound and Waste-water Treatment Process Including Ammonia or Ammonium-ion Compound Using the Activated Sludge

摘要

PURPOSE: A producing method of activated sludge for partially nitrifying an ammonium ion compound, and a processing method of waste water using the activated sludge are provided to improve the efficiency of a waste water processing method. CONSTITUTION: A producing method of activated sludge for partially nitrifying an ammonium ion compound comprises the following steps: obtaining the activated sludge including ammonia oxidizing bacteria containing nitrosospira, nitrosomonas, nitrosococcus, beta-proteobacteria, gamma- proteobacteria, and their mixture; and cultivating the activated sludge using ammonia or an inorganic ammonium ion compound.
