摘　　要：金属表面处理企业车间排放废水,废液量多,处理难度高,环境污染影响大,污染物浓度达到COD_(cr) 10000~20000 mg/L;按分质分类排放收集的原则,本项目"一级混凝沉淀+水解酸化+好氧+二级混凝沉淀"的处理工艺,项目竣工后,废水经处理设施处理后均达到国家《污水综合排放标准》(GB8978-1996)一级标准。There is a lot of waste water discharged from the workshop of metal surface treatment enterprise, which is difficult to be treated and has a great impact on the environment. The concentration of pollutants reaches to CODcr 10000~20000 mg/L. according to the principle of classified discharge and collection by quality, the treatment process of “first-class coagulation + Anaerobic + aerobic + second-class coagulation” of the project is completed, and the waste water reaches to The first level standard of the national integrated wastewater discharge standard (GB8978-1996)..
