摘　　要：该文介绍一项处理地表微污染水源的实验研究。采用"气浮+折板式人工湿地"工艺处理蓟运河地表微污染水,使其达到《地表水环境质量标准》(GB3838-2002)中的Ⅳ类水质标准,实验规模为50 m3/d。结果表明:当PAC加药量为50 mg/L时,水力负荷:0.19 m3/m2·d;进水COD:50 mg/L^100 mg/L;进水NH3-N:4~6 mg/L;进水TN:5 mg/L^12 mg/L;进水TP:0.2~0.5 mg/L,则出水各水质指标均可达到地表水Ⅳ类标准。其中COD的去除率为65%,BOD的去除率为50%,SS的去除率为100%,TN的去除率为70%,NH3-N的去除率为90%,TP的去除率为65%。The 'air floatation + folded plate constructed wetland'technology is used to treat the surface micro polluted water of Ji Canal, and make the water reach the water quality standard of Class IV in Surface Water Environmental Quality Standard(GB3838-2002). The experimental scale is 50 m3/d. The result shows that when PAC dosage is 50 mg/L, the hydraulic load is 0.19 m3/m2.d, the influent COD is 50 mg/L^100mg/L, the influentNH3-N is 4~6 mg/L, the influent TN is 5~12 mg/L and the influent TP is 0.2~0.5 mg/L,and that various water quality indexes of the effluent all reach the surface water standard of IV, in which the removal rate of COD is 65%, BOD is 50%, SS is 100%, TN is 70%, NH3-N is 90% and TP is 65%.
