摘　　要：目前全球可利用的淡水资源很少,而水体污染和富营养化越来越严重。人工湿地以高效率、低投资、低运行费用、低维持技术及其独有生态功能受到众人的青睐。文章主要介绍了人工湿地的净化机理及其对BOD5、氮磷、悬浮物(Suspended matter,SS)等几种污染物的去除效果,为该技术在中国污水处理中的应用提供技术参考。At present, the whole world may use few freshwater resources, but the water pollution and eutrophication are more and more serious. Higher efficiency, lower investment, lower operating cost, lower maintenance technology and its particular ecology lhnction of the constructed wetlands have had people＇s good graces. The purification mechanism of the constructed wetland was introduced, and its removal effect on pollutants such as BOD5, suspended matter, nitrogen and phosphorous was also introduced. The paper afforded reference for technology of constructed wetland using in wastewater treatment in our country.
