摘　　要：文章以三级水平潜流人工湿地为研究对象,湿地种有芦苇、香蒲、慈姑和水葱四种水生植物,对湿地进出水中SS、NH3-N、TN、TP和CODMn进行了为期1 a的水质监测,分析了湿地对微污染河水中污染物的长期进化效果,得出结论:(1)出水污染物含量整体能达到《地表水环境质量标准》中Ⅲ类标准,对各污染物的全年平均去除率在70%左右;(2)温度是影响CODMn去除效果的主要因素;(3)低湿度情况下会促进聚磷菌的生长。In this article, the three-level subsurface flow constructed wetland is not studied. There are four kinds of aquatic plants, Reed, Cattail, Cigu and Scallion, and the SS, NH3-N, TN, TP and CODMnin and out of the wetland were tested for a period of one year. The long-term evolution effect of wetlands on pollutants in micro-polluted river water was analyzed, and the following conclusions were drawn:(1) The overall content of pollutants in the effluent can reach the Class III standard in the “Environmental Quality Standard for Surface Water”. The annual average removal rate of CODMnis about 70%;(2)Temperature is the main factor affecting the removal effect of CODMn;(3)Low humidity will promote the growth of phosphorus accumulating bacteria.
