NITRATION METHOD OF AMMONIA NITROGEN-CONTAINING WATER |
摘要 |
PROBLEM TO BE SOLVED: To stably carry out nitrous acid nitration of ammonia nitrogen- containing water maintaining a DO concentration in a nitration tank to a low degree by controlling an air amount of aeration in aeration in the presence of ammonia oxidation bacteria. SOLUTION: In the nitration method for ammonia nitrogen-containing water, a concentration of ammonia in a nitration solution in the nitration tank 1 or in the nitration solution flowing out from the nitration tank 1 is measured and the nitrous acid nitration is carried out by adjusting the air amount of aeration such that this measurement value becomes 20 mg/L or higher.
