摘　　要：以河北省某乡镇污水处理厂为例,探究低温条件下人工湿地深度净化污水处理厂尾水的效能,采用水平潜流人工湿地,设计处理规模6 000 m^(3)/d。结果表明,在实际进水不足设计值10%、冬季进水水温不足5℃的条件下,该工艺对COD、NH_(3)-N、TN、TP去除率分别为56.2%、67%、38.7%、41.3%,出水水质可稳定达到GB 3838—2002《地表水环境质量标准》的Ⅱ类标准,具有较好的环境效益和经济效益。To explore the efficiency of constructed wetlands for advanced purification of municipal wastewater treatment plant effluent under low-temperature,a horizontal subsurface flow constructed wetland was used as a case at a rural town treatment plant in Hebei Province,designed with a treatment capacity of 6000 m^(3)/d.The results showed that under conditions where the actual inflow was less than 10%of the design value and the winter inflow temperature was below 5℃,the process achieved removal rates of 56.2%for COD,67%for NH3-N,38.7%for TN,and 41.3%for TP.The effluent water quality could stably meet the classⅡstandards of the GB 3838—2002“Environmental quality standards for surface water”,showed good environmental and economic benefits.
