摘　　要：临沂市武河人工湿地工程采用多级表面流人工湿地工艺对以城市污水处理厂出水为主的污染河水进行深度处理,其占地面积为866.67 hm2、处理规模为30×104m3/d。长期监测结果表明,在年均进水COD为52.51 mg/L的情况下,处理后年均出水COD为20.88 mg/L,达到了Ⅳ类地表水水质要求。应用WASP水质模型模拟湿地对COD的去除效果,所得拟合结果与实际运行效果基本吻合。研究结果可为规模化人工湿地工程的优化设计和建设提供技术参考。Wuhe constructed wetland （CW） using multistage surface flow technology was used to treat river water polluted by effluent from a sewage treatment plant. Wuhe constructed wetland covers an area of 866.67 hm^2, and the treatment capacity is around 30 ×10^4 m^3/d. The monitoring results showed that the annual average COD in the influent and effluent of the CW were 52.51 mg/L and 20.88 mg/L, and the effluent quality met grade Ⅳ of national surface water standards in China. In addition, WASP model was applied to simulate COD removal efficiency in the CW, and the simulation was basically consistent with the actual results in the CW. The WASP could be useful for the design and construction of large-scale constructed wetlands.
