摘要
有机化工废水成分复杂、浓度高、毒性大、色度深、难以生物降解。采用微电解技术可以破坏废水中污染物的结构,使有机废水易生物降解;后续采用ABR+SBR技术处理,COD去除率可达到96%以上,BOD去除率达98%以上,出水COD、BOD符合GB8978-1996《污水综合排放标准》一级标准。
Organic chemical wastewater is complex composition,high concentrations,toxic,deep color,difficult to biodegradation.Adopted micro-electrolysis technology can destroy the pollution structure,made organic wastewater become more biodegradable.Then adopted ABR＋SBR technology,the COD removal rate reached 96 %,BOD reached 98 %,effluent met GB8978-1996 standard A.
