摘　　要：考察了几种高效复合微生物群在不同水力停留时间下对城市污水的处理效果,用空白活性污泥作对照,对出水CODCr值及CODCr的去除率进行了对比和分析。结果表明,在单一菌体与活性污泥混合处理时,光合细菌一活性污泥系统混合处理效果最佳,水力停留时间在6 h时,去除率大于90％;在多菌体与活性污泥混合综合处理时,高效复合微生物菌群结合活性污泥系统,随着进水CODCr的提高,CODCr去除率始终保持在90％以上,具有良好的去除效果和相应的耐冲击性。Comparing to the active sludge, the effluent CODCr and CODCr removal rates of four efficiently coupling microorganism were studied by changing HRT. As a result, the PSB-active sludge system was best, and the CODCr removal rate was beyond 90% at 6 HRT. With the raising of influent CODCr, the combined efficiently coupling microorganism-active sludge system was stably larger than that single active sludge system, and its CODCr removal rate was beyond 90%.
