污水生化处理过程仿真及在A~2/O工艺改进中的应用

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 A2/O technology was modified with reason.The internal recycle flow was canceled without the affection of effluence indexes.By the software, the modified A2/O technology process was simulated respectively using dry, rain and storm weather files.The modification was proved reasonable by the...
