METHOD OF WASTEWATER TREATMENT USING AN ANAEROBIC REACTOR HAVING A BIOLOGICAL NITRIFICATION PROCESS CONNECTED A CATION EXCHANGE MEMBRANE

摘要

PURPOSE: An anaerobic tank and a waste water treatment method thereof are provided to simplify a waste water treatment process and reduce processing time. CONSTITUTION: An anaerobic tank(2) includes a nitrification basin(5) which is connected to a positive ion exchange membrane(1). The positive ion exchange membrane selectively passes through ammonia to a nitrification basin. The positive ion exchange membrane selectively passes through nitrite which is generated in the nitrification basin. The nitride which is flowing into after passing through the positive ion exchange membrane or the denitrification of the nitrate is executed in the anaerobic tank. An ammonia removal reaction is executed in the nitrification basin.
