摘　　要：减少排向水体的氨氮和总磷是促进水环境质量好转的有效措施之一。本文根据湿地植物的生长期特点,分不同时段进行了氨氮和总磷净化效果对比。试验表明,人工湿地系统对氨氮的去除率可达到87.1%,对总磷的去除率可达到91.8%,说明了在北方地区利用人工湿地系统去除市政污水中的氨氮和总磷等污染物的可行性,处理方法符合目前水环境生态保护趋势要求。Reducing ammonia nitrogen（ NH3 -N） and total phosphorus（TP） discharged into the water is one of the effective ways to improve the water environmental quality. Based on the growing character of the plants in wetlands, the purification efficiency is compared during different representative period in this paper. The experiment result shows the removal rate of NH3 -N and TP can reach 87. 1% and 91.8% by constructed wetland system. The feasibility of purifying municipal sewage by constructed wetlands system is proved and the technics accords with the tendency of protecting water ecology environment presently.
