摘　　要：表面流人工湿地是一种正在发展中的污水处理技术,这种污水处理工艺具有操作简单,维护和运行费用低廉等优点,适用于小城镇的污水处理,有极其广阔的应用前景。本文概括性地介绍了表面流人工湿地的相关概念、构建方式,探讨了有机物、悬浮物、氮和磷等的去除机理,并剖析了一些关键设计点,如水力停留时间、面积、长宽比、水深、植物选择和进出口等。Surface flow constructed wetlands is being developed sewage treatment, this wastewater treatment technology operates easily, has some advantages in maintenance and operation cost, is applied to small towns sewage treatmen, has extremely wide application prospect. This paper summarily intoduced related concepts and construction methods of the surface flow constructed wetlands, discussed the removal mechanism of the organic matter, suspended solids, nitrogen and phosphorus, analyzed some design cruxes such as hydraulic residence time, wetlands area, aspect ratio, depth,plant selection and inlet-outlet control, etc.
