Problems solved by technology

[0002] The fine chemical industry often produces high-concentration ammonia-nitrogen wastewater. The concentration of ammonia nitrogen and COD in the wastewater is high. COD will cause the deterioration of the water quality of natural water bodies, destroy the water body balance, and cause the death of almost all organisms except microorganisms, which is extremely harmful to the water environment. It is very difficult to deal with
