Treatment effect of vertical flow wetland to domestic wastewater under different hydraulic loading

Zhang Li

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.NH+4—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.
