Characteristics of aluminum sludge composite filler and its application in constructed wetlands

  • 摘要: 利用铝污泥、钢渣和沸石制备了3种铝污泥复合填料——铝污泥-沸石、铝污泥-钢渣、铝污泥-沸石-钢渣,研究了其物理特性和对磷的等温吸附性能,并应用于人工湿地小试系统中,探讨其对湿地水质的净化效果。结果表明:相较铝污泥和传统湿地填料,3种复合填料具有较大的体积密度、孔隙率和比表面积;3种复合填料对磷的吸附效果存在较大差异,表现为铝污泥-钢渣>铝污泥-沸石>铝污泥-沸石-钢渣;3种复合填料对人工湿地进水中化学需氧量(CODCr)的去除率无显著差异,均为70%左右;对总磷(TP)、总氮(TN)、氨氮(NH3-N)的去除率差异较大,其中铝污泥-钢渣、铝污泥-沸石对TP去除率较高(93%以上),铝污泥-沸石、铝污泥-沸石-钢渣对TN和NH3-N去除率较高(TN高于65%,NH3-N高于77%);铝污泥-沸石复合填料对人工湿地污染物去除的综合效果最好,可使人工湿地出水水质达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准。
