摘　　要：针对传统污水处理系统存在的问题,提出SBR-PBR-改性膜组合工艺对市政污水进行处理,对组合工艺的运行参数进行优化和效果评估。试验结果表明,厌氧程序120 min→好氧程序170 min→缺氧程序120 min→好氧程序10 min→待机4 min,水力停留时间为2 d的SBR模式下,选择栅藻,反应温度和光照强度分别为25~30℃和3500 lux的PBR运行参数下,处理的市政污水总氮、总磷含量分别为7 mg/L和0.1 mg/L,远低于一级A排放标准;表现出较好的环保性能和抗污染性能。Aiming at the problems existing in traditional wastewater treatment system,SBR-PBR modified membrane combined process was proposed to treat municipal wastewater.the operation parameters of the combined process were optimized,and the effect was evaluated.The test results showed that under the SBR mode of 120 min of anaerobic program-170 min of aerobic program-120 min of anoxic program-10 min of aerobic program-4 min standby and 2 days of hydraulic retention time,and the PBR operating parameters of 25~30℃and 3500 lux,the total nitrogen and total phosphorus contents of the treated municipal sewage are 7 mg/L and 0.1 mg/L,respectively,which are far lower than the discharge standard of Class A,showing good environmental protection and anti pollution performance.
