METHOD OF REMOVING HIGH CONCENTRATION OF AMMONIA FROM REJECT WATER IN SEWAGE TREATMENT PROCESS BY USING METHANE- AND METHANOL-DEPENDENT SYMBIOTIC BACTERIA AND BIOGAS

摘要

The present invention relates to a method of removing a high concentration of ammonia from reject water in a sewage treatment process by using methane- and methanol-dependent bacteria and biogas, and more specifically, to ammonia removal in a methane oxidation reactor comprising a methane- and methanol-dependent microbial consortium and biogas, for reducing a nitrogen concentration in reject water that is inevitably generated during the sewage treatment process. By using a synergistic action of the methane- and methanol-dependent microbial consortium and biogas generated in a sewage treatment plant, the present invention reduces nitrogen loads by directly treating a high concentration of ammonium without diluting the reject water from the sewage treatment process, and maintains a desirable water quality of effluents by increasing nitrification efficiency, and thus can improve the water quality of effluent-receiving streams.
