摘　　要：在盐度为0.15%、0.3%和0.6%条件下,考察炉渣填料组合潜流人工湿地对生活污水的处理效果。结果表明,在低盐度情况下,盐度的提升对人工湿地的影响作用不大,各个污染物指标的去除率都达到较高水平。在盐度0.6%条件下组合潜流人工湿地2级湿地对污染物的去除率各不相同,垂直潜流人工湿地对NH4+-N和COD的去除率比水平潜流人工湿地高;水平潜流人工湿地对NO3--N、TN和TP的去除率比垂直潜流人工湿地高。The research is mainly about the removal effect of domestic wastewater treated by hybrid subsurface flow wetlands with slag as substrate material at salinity of 0.15%、0.3% and 0.6%. The result indicate that the influence of improve salinity on hybrid subsurface flow wetlands is limited, removal rate of pollutants are satisfactory. The removal rate of the two-stage reactor of hybrid subsurface flow wetlands are different, the removal rate of NH4＋-N and COD in vertical-flow constructed wetland is better than in horizontal subsurface flow wetland, however, the removal rate of NO3--N, TN and TP in horizontal subsurface flow wetland is better than in vertical-flow constructed wetland.
