摘　　要：由于目前运行的污水处理厂进水COD值远远超过了原有的设计负荷，严重影响了活性污泥系统的正常运行。文章研究了微电解强化活性污泥技术去除模拟生活污水中COD的效果。试验结果表明：COD平均去除率为92.4％，尤其在进水COD较高时，微电解强化效果更明显。此外还讨论了进水的COD、氨氮、无机磷负荷对系统去除COD的影响。结果表明：COD、氨氮负荷增加时，COD去除率增大；无机磷负荷增加时，COD去除率不变。通过实际生活污水的试验证明了微电解一活性污泥法可用于实际污水的处理。Because the influence of COD largely exceeds the original design load in the present sewage treatment plants, it seriously affects normal circulation of the active sludge process. This article studied active sludge technology enhanced by micro-electrolysis method removal COD in the simulated sewage. The experiment results showed that the COD average removal rate was 92.4%, especially the treatment effect of the active sludge process enhanced by the micró-electrolysis method was more obvious in the influence of high COD concentration. In addition, the influences of COD removal on the influem concentrations of COD, NH4^＋ -N, phosphorous were discussed. The result indicated： when the COD, NH4^＋ -N concentrations increased, the COD elimination rate also increased： When the phosphorous concentration increased, the COD elimination rate decreased. The active sludge process enhanced by micro-electrolysis method can be used for the actual sewage treatment by the experiment dealing with actual sewage.
