Title:
SEWAGE TREATMENT SYSTEM BASED ON ANAEROBIC AMMONIUM OXIDATION METHOD IN WATER TREATMENT PROCESS IN SEWAGE TREATMENT PLANT
Document Type and Number:
WIPO Patent Application WO/2018/221924
Kind Code:
A1
Abstract:
The present invention relates to a sewage treatment system which uses recycle water in order to apply an anaerobic ammonium oxidation method to a water treatment process (a mainstream treatment process) and stably supply nitrite nitrogen necessary for an anaerobic ammonium oxidation reaction. The present invention can treat nitrogen and phosphorus at the same time in the water treatment process by applying the anaerobic ammonium oxidation reaction method, and reduce the sewage treatment cost and the pollution load by using the recycle water as a source of supply of the nitrite nitrogen.
