摘　　要：为探究SBR工艺处理城市生活污水的最佳反应工况,采取“进水-好氧-缺氧-厌氧-好氧-沉淀-排水-闲置”的工艺流程,将脱氮除磷过程分离开来,对分段进水最佳流量比和各阶段最佳反应时间进行研究。结果表明:对于总磷和COD的去除,A进水模式(流量比为7∶3)去除率最高,分别为83.69%和91.64%;对于总氮和氨氮的去除,C进水模式(流量比为9∶1)的进水方式去除率最高,分别为83.40%和93.50%。同时,研究发现有效反应时间为12 h时为脱氮除磷的最佳运行工况。In order to explore the optimal reaction conditions of SBR for treating urban domestic wastewater,the process flow of"raw water-aeration-anoxia-anaerobism-aeration-sedimentation-drainage-idleness"was used to separate the removal of nitrogen and phosphorus,and the optimal flow ratio of staged influent and the optimal reaction time of each stage were studied.The results showed that for the removal of total phosphorus and COD,the highest removal rates were 83.69%and 91.64%in influent A mode(flow ratio 7∶3).For the removal of total nitrogen and ammonia nitrogen,the C influent mode(flow ratio 9∶1)had the highest removal rate with 83.40%and 93.50%,respectively.At the same time,it was found that the optimal operating condition for nitrogen and phosphorus removal was when the effective reaction time was 12 h.
