摘 要: 以美人蕉(Canna indica)、天堂草(Cynodon dactylon)为试材,通过盆栽试验研究了植物对污泥中Cu、Zn、Pb、Cd、Cr和Ni等重金属的吸收、分布与去除效果.结果表明,美人蕉和天堂草地下部的重金属含量普遍高于地上部,于盆栽土中分别施用质量分数50%和25%的污泥后,美人蕉和天堂草对Zn、Ni、Cd的去除效果较好. Canna indica and Cynodon dactylon were used to remove the heavy metals of Cu, Zn, Pb, Cd, Cr and Ni in potted plants in the sludge land application. The results showed that concentrations of heavy metals in underground part of Canna indica and Cynodon dactylon were usually higher than that in aerial part. When the dosage of sludge for Canna indica and Cynodon dactylon were respectively 50% and 25%, Zn, Ni and Cd could be removed effectively.
