人工湿地处理10×10~4m^3/d工业园尾水设计实例

Large-scale Example of Effluent from Industrial Park with Constructed Wetland Process

采用人工湿地处理某工业园污水厂尾水,处理规模为10×104m3/d,主体工艺采用垂直流人工湿地+水平流人工湿地+生态塘,湿地设计水力负荷为0.64 m3/(m2·d),设计出水的主要水质指标达到《地表水环境质量标准》(GB 3838—2002)Ⅳ类标准,实际运行数据表明,该工艺运行稳定,出水各项指标均达到排放要求。

The effluent from sewage treatment plant in an industrial park was treated with constructed wetland process,and the treatment capacity was 10 × 10^4m^3/d. The main treatment processes were vertical flow constructed wetland,horizontal flow constructed wetland and ecological pond,and the constructed wetland design load was 0. 64 m^3/（m^2·d）. The design effluent quality met the Ⅳ criteria specified in the Environmental Quality Standards for Surface Water（GB 3838- 2002）. The operation data indicated that the combined process was stable in operation,and the effluent quality met the discharge requirements.
