摘　　要： 基于国际水协会IWA发布的国际评价基准Benchmark,建立了与污水处理厂实际特性相近的标准仿真平台。对污水处理传统A2/O工艺做了合理改进,在不影响出水水质的情况下,取消内回流。应用该平台分别对晴天、雨天与暴雨三种天气的工艺过程模拟,验证了工艺改进的合理性。仿真结果表明,与传统A2/O工艺相比,出水指标差别不大,但污泥泵能耗降低约50%。 Based on the Benchmark published by the International Water Association （IWA）, the standard simulation software was developed. The process during the software was close to the real wastewater treatment plants. The traditional A^2/O technology was modified with reason. The internal recycle flow was canceled without the affection of effluence indexes. By the software, the modified A^2/O technology process was simulated respectively using dry, rain and storm weather files. The modification was proved reasonable by the simulation result. Compared with the traditional A^2/O technology, the difference on effluence indexes is slight, but 50% pumping energy is saved.
