摘　　要：结合泰安市污水处理厂多年的实际运行情况,总结分析了A+A^2O工艺对COD、SS、TN、TP的去除效果。实践表明,A+A^2O工艺对COD、SS去除率高,但在进水BOD5值较低而SS值偏高的情况下,很难使氮、磷的去除效果同时达到最佳,若根据要求侧重一个方面,则效果更好。Based on the actual operation for several years in Tai＇ an Wastewater Treatment Plant, the removal effect of A ＋ A^2O process on COD, SS, TN, and TP was summarized. The practice shows that the process has a high removal rate for COD and SS. However, it is difficult to achieve the optimal removal rate for nitrogen and phosphorus under the condition of lower influent BOD5 and higher influent SS, but the favorable effect can be obtained if laying particular stress on either nitrogen or phosphorus removal.
