| 摘 要： | 反应介质的选择是可渗透反应墙(PRB)系统原位处理污染地下水的一个关键问题。本实验采用两种混合介质A(陶粒与活性炭的混合物)和B(沸石与活性炭的混合物),对修复被渗滤液污染的地下水的可行性进行了研究。结果表明,混合介质A和B对CODCr的平均去除率分别达到了71.8%和63.4%;对NH4 的平均去除率分别为13.5%和58.7%;对重金属的去除,反应介质B则优于A。因此,PRB反应介质的选择要根据污染物的性质而定。

| Abstract: | The selection of the reactive media is a key problem of in-situ remediation of contaminated groundwater in permeable reactive barrier(PRB) system.Two mixture media,viz.A(a mixture of ceramic grain and activated carbon) and B(a mixture of the zeolites and activated carbon) were used by the authors(with studying t)heir feasibility of remedying the leachate polluted groundwater.The experimental results indicate that the average COD_(Cr) removal ratio of the media A and B was up to 71.8% and 63.4%,and the NH~ _4 average removal efficiency was 13.5% and 58.7%,respectively.However,the heavy metals 'removal efficiency of media B is better than that of A.Therefore the selection of reactive media of PRB mainly depends on property of conteminants. |
