摘　　要：针对国内外研究现状,分析了人工湿地脱氮除磷的影响因素,介绍了湿地应用中较好的池型、湿地植物和填料介质的类型。认为采用往复流有助于形成脱氮的环境,种植具有浓密和较长根系的湿地植物如芦苇、香蒲等有利于提高脱氮效率,种植具有茂盛枝叶的湿地植物如凤眼莲、浮萍等可以辅助除磷。同时认为沸石床去除氨氮效果更为明显,碎石床除磷效果较好,而综合考虑脱氮除磷效果,粉煤灰床则具有优势。In view of the research on subsurface constructed wetland,the paper makes an overall analysis regarding some factors of nitrogen and phosphorus removal and discusses the types of the better ponds,wetland plants and padding mediums in the wetland application.The efficiency of the nitrogen removal can be raised with reciprocation class,by growing the plants with the thick and long roots,such as Phragmites communis Trin,Typha latifolia.The plants with luxuriant branches and leaves,such as Eichhornia crassipes（Mart.） Solms-Laub and Lemna minor L,are quite beneficial to the phosphorus removal.Meanwhile,the zeolite bed is more effective in eliminating ammonia and nitrogen.The crushed stone bed affects obviously on the phosphorus removal and the pulverized coal ash bed bears some advantages.
