摘要
Abstract
A hydroponic experiments for emergent plant Scirpus validus was carried out to measure it' s removal effection on 5 heavy metals( Cu、Zn、Ni、Mn、Cd) in mine drainage. The results suggested that Scirpus validus had an effective concentration removal rate on Ni、Mn、Cd,with a high rate exceed 80% ;In addition,it' s concentration removal rate on Cu、Zn was not so good. It was proved that the heavy metals absorbed into Scirpus validus were mainly gathered in it's root under ground, and there was a synergistic effect between 5 heavy metals when they been removed. Meanwhile, a positive correlation between Scirpus validus' s transpiration and it' s removal effection on 5 heavy metals has been proved, finally, after purify with Scirpus validus, the mine drainage has reached the first level of integrated wastewater discharge standard(GB 8978-1996).关键词
