摘　　要：采用电解-好氧生物法联合处理酸性大红G模拟废水,三维电解反应器填料为活性炭与玻璃珠混合物,平板电极材料为石墨,通过正交实验确定的最佳实验条件为:电解时间150 min,活性炭/玻璃珠体积比为2∶1,槽电压20 V、pH为5、Na2SO4投加量1.5 g/L,进水初始浓度2 000 mg/L。此时COD去除率及色度去除率分别可达49.78%和81.45%,废水BOD5/COD由0.12提高到0.42。电解后的废水采用生物接触氧化法处理12 h后,出水COD为48 mg/L,色度120倍,达到综合污水排放二级标准。The simulated acid red G wastewater was treated with electrolysis-aerobic biological process , when the filler of the three-dimensional electrolysis reactor was the mixture of activated carbon and glass bead, the plate electrode was graphite. The optimum parameters were as follows：the electrolysis time was 150 min, the volume ratio of carbon to glass bead was 2： 1, the cell voltage was 20 V, pH was 5, the dosing quantity of Na2 SO4 was 1.5 g/L, the concentration of influent was 2 000 mg/L,which were confirmed by orthogonal experiment. And under such operation parameters, the removal rate of COD and chroma of the simulated wastewater can reach 49.78% and 81.45% , respectively, and the BOD5/COD can increase from 0. 12 to 0.42. Meanwhile, the wastewater after electrolysis treated with biological oxidation process within 12 h, the COD and chroma of the effluent wastewater were 48 mg/L and 120 （times） , which can meet the integrated wastewater discharge standard.
