MAINSTREAM ANABOLIC AMMONIUM OXIDATION IN WASTEWATER TREATMENT PLANT FOR IMPROVING EFFICIENCY OF REMOVAL OF NITROGEN AND PHOSPHORUS

摘要

The present invention relates to a sewage treatment system using an anaerobic ammonium oxidation reaction method in a water treatment process (main treatment process) and using reflux water to stably supply nitrite nitrogen required for anaerobic ammonium oxidation reaction, By applying the oxidation reaction method, it is possible to simultaneously treat nitrogen and phosphorus in the water treatment process and reduce the sewage treatment cost and pollutant load by using the counter current water as the nitrite nitrogen source.
