摘　　要：介绍了应用生物接触氧化池一膜生物反应器组合处理电厂化学再生废水和生活污水的混合废水。试验表明，当进口有机物CODcr在300-500mg／L，TOC在100md/L左右，Cl^-1质量浓度为4500mg／L时。操作条件pH：6～8，DO2-3mg／L，停留时间为8h，水温在20-25℃时，出口CODcr小于100mg／L，平均TOC10mg／L左右，CODcr去除率在85％，TOC去除率为90％左右。The treatment of the mixed waste water, consisting of chemical regeneration waster water and residential sewerage from power plants, by using the biological contact oxidation process-membrane-biological reactors is recommended. Experiments show that when the inlet organics CODcr is between 300 and 500 mg/L, TOC about 100 mg/ L, the concentration of Cl^- about 4 500 mg/L, pH between 6 and 8, DO between 2 and 3 mg/L, detention time about 8 h, water temperature between 20 and 25℃, the outlet CODcr is less than 100 mg/L, the average TOC is about 10 mg/L, the CODcr elimination rate is 85%, and the TOC elimination rate is about 90%.
