METHOD AND APPARATUS FOR ANAEROBIC AMMONIA OXIDATION

摘要

PROBLEM TO BE SOLVED: To provide an anaerobic ammonia oxidation method capable of accumulating anaerobic ammonia oxidation bacteria at a high speed, increasing denitrification speed when denitrifying both of ammonia and nitrous acid simultaneously by using the anaerobic ammonia oxidation bacteria, and enhancing efficiency of waste water treatment.

SOLUTION: In the anaerobic ammonia oxidation method, both ammonia and nitrous acid are simultaneously denitrified by using the anaerobic ammonia oxidation bacteria in an anaerobic ammonia oxidation tank 12. Ammonia concentration in the anaerobic ammonia oxidation tank 12 is controlled to be 50 to 100 mg/L and nitrous acid concentration is controlled to be 30 to 80 mg/L.
