人工湿地技术在污水处理中的应用

Abstract

人工湿地法处理污水技术是目前国际污水处理研究领域的热点。本文主要从人工湿地的分类、净化机理、影响净化的因素、国内外应用现状和应用前景等方面对人工湿地技术进行了阐述。人工湿地系统是一个完整的生态系统，是正在不断得到研究应用和发展的污水处理实用新技术，具有投资低，出水水质好，抗冲击力强，增加绿地面积，改善和美化生态环境，操作简单，维护和运行费用低廉等优点。这项技术适合我国国情，尤其适合广大农村、中小城市的污水处理，具有极其广阔的应用前景。 Technique of wastewater treatment with constructed wetlands is currently the highlight in the field of international wastewater treatment research. This review briefly described the classification of constructed wetland, the mechanisms of cleaning wastewater, the factors affecting cleaning, the present situation of the application, and the development direction of constructed wetland application. The constructed wetland system is an integrated ecosystem. It’s also a new wastewater treatment technology being developed and applied. It has such advantages as low investment, high quality effluent, good impact resistance, ecological environment improvement and beautification, increase of green land, simple performance, cheap operation fee, and so on. The constructed wetland system is a suitable technology for wastewater treatment in China, which has wide application prospects especially in rural areas and small cities.
