摘　　要：以某淀粉生产企业生产加工废水和厂区生活废水的综合处理为例,介绍了以PEIC反应器-A/O活性污泥法为主体工艺的废水综合处理工程。该工程设计规模为7 300 m3/d,其中淀粉生产废水6 800 m3/d,生活废水500m3/d,进水COD、BOD5分别为8 000、500 mg/L。经调试运行,采用该工艺处理效果良好,出水COD为60 mg/L、BOD5为10 mg/L、SS质量浓度为10 mg/L、TN质量浓度为15 mg/L、TP质量浓度为1 mg/L,远低于淀粉工业水污染物排放标准(GB 25461-2010)中的一级排放标准限值,且利用PEIC厌氧反应器产生的沼气发电,具有可观的经济效益。The operation of PEIC anaerobic reactor-A/O activated sludge processes for the treatment of corn starch production wastewater and domestic sewage with high concentration of organics was introduced through the project practice. The project design scale is 7 300 m^3/d, including starch production waste water is 6 800 m^3/d, domestic sewage of 500 m^3/d. When the COD in the influent was 8 000 mg/L, the COD, BOD, SS, TN, TP in the effluent were 60, 10, 10, 15, 1 rng/L respectively. Effluent quality was stable and superior to the requirement of level 1 standard in discharge standard of water pollutants for starch industry（GB 25461 -2010）. In addition, using biogas generated power from the PEIC anaerobic reactor, with considerable economic benefits.
