采用表流+砾石潜流和表流+炉渣潜流2组复合人工湿地处理高污染河水,对2组复合人工湿地的净化效果进行了对比研究,考察了基质类型对复合系统中二级潜流湿地的影响作用,并探究了2种基质的除磷能力。研究结果表明:两组复合湿地对SS、COD、BOD5的去除主要在一级表流湿地中完成,避免了在二级潜流湿地中堵塞;炉渣复合湿地更利于硝化的进行和对磷的去除。炉渣对磷的去除率和抗负荷能力均高于砾石。
採用錶流+礫石潛流和錶流+爐渣潛流2組複閤人工濕地處理高汙染河水,對2組複閤人工濕地的淨化效果進行瞭對比研究,攷察瞭基質類型對複閤繫統中二級潛流濕地的影響作用,併探究瞭2種基質的除燐能力。研究結果錶明:兩組複閤濕地對SS、COD、BOD5的去除主要在一級錶流濕地中完成,避免瞭在二級潛流濕地中堵塞;爐渣複閤濕地更利于硝化的進行和對燐的去除。爐渣對燐的去除率和抗負荷能力均高于礫石。

Two groups of constructed wetland systems,including surface flow+gravel undercurrent and surface flow+slag undercurrent,have been used for treating highly polluted river water. The purification results of the two systems are compared. The effects of the types of substrates on the two stages of the undercurrent wetlands in the complex systems are investigated and the dephosphorization capacities of the two kinds of substrates are explored. The results of the research show that the removal of SS,COD,BOD5 are mainly accomplished in the first stage of surface flow constructed wetland,avoiding blocking in the second stage undercurrent wetland. The slag complex wetland is more beneficial to the accomplishment of nitrification and the removal of phosphorus. Slag has better capacities for phos-phorus removing rate and load resisting than gravels.
