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. Ammonia nitrogen is an important factor causing eutrophication of water bodies, and its discharge volume is large, its composition is complex, and its toxicity is strong, which is extremely harmful to the water environment. And it is very difficult to deal with
