摘　　要：采用膜膜强化集成工艺,对混合型城市污水进行脱氮除磷效果试验研究。试验结果表明,COD、NH3-N、TN及TP去除率分别达到80%、96%、60%及88%,系统平均出水COD为25 mg/L,NH3-N、TN及TP的质量浓度分别为0.9、13、0.44 mg/L。系统运行稳定,各项指标均可达到国家一级A标准(GB 18918-2002)。To treat combined municipal wastewater, the membrane strengthen integration process was suggested and tested in this pilot study. The removal rates of COD, total nitrogen, ammonia and total phosphorus were 80%, 96%, 60% and 88%, respectively.The average concentration of COD, ammonia, total nitrogen and total phosphorus in effluent were 25, 0.9, 13 and 0.44 mg/L, which met the I-A wastewater discharge standards of China（GB 18918--2002）. The process was operated stably.
