摘要: 以沈阳浑南垂直流人工湿地模拟系统为研究对象,考察了湿地模拟系统对生活污水的处理效果,重点研究了不同水力负荷的影响。结果表明,垂直流湿地模拟系统对生活污水具有较好的处理效果,出水NH4+-N、TP、CODCr和BOD5均达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A 标准;水力负荷为0.156 t/m2•d时,是垂直流湿地模拟系统运行的最佳负荷。

Abstract: The treatment effect of wetland simulation system to domestic wastewater was investigated in vertical flow wetland (VFW) artificial wetland simulation system of Hunnan in Shenyang. The influences of the different hydraulic loadings were analyzed. The results indicate that the treatment effect of VFW simulation system to domestic wastewater is better. NH4+-N contents, TP contents, CODCr contents and BOD5 contents of effluent reach band-A in discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002). The optimal hydraulic loading of VFW simulation system is 0.156 t/m2•d.
