摘要 人工湿地具有投资少、运行费用低、处理效果好、运行稳定、操作简单等特点,在国外已被广泛地运用于处理城市生活污水,目前国内也有不少典型工程实例,采用生物滤池作为前处理工艺,运用自由表面流和水平潜流两级人工湿地处理江南某城市的生活污水设计表明,其出水水质优于污水综合排放标准中的二级标准,每吨水投资为286元,处理费用为0.15元/m3,具有较好的应用前景。 Constructed wetland has a characteristic of low investment and run charge, steady work condition, simple operation and so on. It has been used for treatment of municipal wastewater in foreign country, and now is carried out in some domestic typical project. Using biological filter for pre - treatment process following by free surface flow wetlands and horizontal subsurface flow wetlands to treat municipal wastewater in south china, the flow water quality is better than the second level flow standard of wastewater,the investment and operation cost is respectively 286 Yuan and 0.15 Yuan per cubic wastewater,it has a bright use foreground.
