中文摘要：

目前我国的水环境污染形势日益严重,绝大多数江河湖海的污染负荷日益增加,许多水体的自净能力逐渐在丧失。人工湿地处理系统具有投资与运行费用低、维护管理简便、耐冲击负荷能力强、生态景观改善效果明显等优点,因此得到广泛的关注。主要从人工湿地的组成及其功能论述了人工湿地废水处理中污染物的降解机理及去除途径,为我国人工湿地治理污染物的研究以及实际工程应用提供有价值的理论参考。

英文摘要：

The situation of water environment is becoming increasingly serious in our country.The pollution loadings of most rivers or lakes are increasing,and the self-purification capability of many surface waters is gradually losing.Constructed wetlands got much concern because of many advantages,such as low investment and operating costs,convenient maintenance and management,strong resistance to shock loading,effectively improve the ecological landscape.The removal of pollutants and their degradation mechanism were discussed which based on the compositions and their works of wetland,and that may provide certain of valuable theoretical support on research and application on the wetland for treating pollutants.
