摘　　要：总结了水平潜流人工湿地的脱氮除磷机理,分析了进水水质、植物、基质、温度和水力停留时间这5种影响处理效果的主要因素,从不同角度论述了提高脱氮除磷效果所采取的措施,并探讨了水平潜流人工湿地存在的局限性和发展趋势。The nitrogen and phosphorus removal mechanisms in constructed wetlands with horizontal sub-surface flow（HF CWs） are summarized,and dominant factors that affect the treatment performance,including the types of wastewater,macrophytes,substrate,temperature,and hydraulic retention time（HRT）were analyzed.Measures for improving removal efficiency of nitrogen and phosphorus were also determined from different aspects.The application limitation existing in the running of the HF CWs is discussed,and the developmental tendency is predicted.
