摘　　要：污染物在人工湿地中的去除机理包括了物理、化学及生物学过程,人工湿地能同时去除多种污染物质正源于其中的协同机制。影响人工湿地水质净化的主要因素包括:植物、碳源、基质、溶解氧和微生物。探讨了人工湿地对氮、磷和有机物的去除机理,同时论述了影响人工湿地去污的主要因素,并对今后的相关研究方向进行了展望。The mechanism of pollutant removal in constructed wetlands （CWs）includes physical, chemical and biological processes. Just because of its synergistic mechanism, constructed wetland can remove many kinds of pollutants at the same time. The main influential factors of water purification in CWs include ： plant, carbon source, substrate, dissolved oxygen and microorganism. The removal mechanism of nitrogen, phosphorus and organic substances by CWs are discussed, and the main influential factors of pollutant removal are investigated. In addition, a prospect for relevant research directions in future and suggestions are given.
