Title:
WASTE WATER TREATMENT SYSTEM
Document Type and Number:
Japanese Patent JP2016131974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a waste water treatment system.SOLUTION: A waste water treatment system according to the present invention removes at least a part of chemical oxygen demand and nitrogen-containing compounds in waste water, and comprises a decarbonization anaerobic fluidized bed reactor and a nitrogen removal fluidized bed reactor. The decarbonization anaerobic fluidized bed reactor sequentially hydrolyzes, oxidizes, and methanizes most of chemical oxygen demand mainly in the waste water to produce methane. The nitrogen removal fluidized bed reactor converts ammonia nitrogen and surplus chemical oxygen demand in the waste water to nitrogen via a nitrification reaction, an autotrophic denitration reaction, and a heterotrophic denitration reaction.SELECTED DRAWING: Figure 1
