摘　　要：建立以李氏禾为湿地植物,红壤和沸石为混合填料的湿地系统,研究了李氏禾人工湿地对电镀废水的处理效果。结果表明,李氏禾在Cr、Cu、Ni质量分数已达0.049 094%、0.019 538%、0.010 701%的污染湿地中仍能成活。该湿地系统对Cr、Cu、Ni的去除率分别达到63.86%～84.76%、91.78%～96.09%、56.65%～74.62%。因此,李氏禾人工湿地系统在处理重金属污染水体方面表现出极强的应用潜力。A constructed wetland planted with Leersia hexandra Swartz,using red soil and zeolite as mixed fillers,has been set up to remove Cr,Cu and Ni from electroplating wastewater.The results show that L.hexandra could still survive in wetland contaminated by Cr,Cu and Ni with mass fractions of 0.049 094%,0.019 538%,and 0.010 701%,respectively.The removing rates of Cr,Cu and Ni in the constructed wetland are 63.86%-84.76%,91.78%-96.09%,and 56.65%-74.62%,respectively.Thus,the constructed wetlands planted with L.hexandra have very strong potential for applying to the removal of heavy metal from contaminated water.
