摘　　要：通过实验研究筛选出一种经济、高效的用于修复铬污染地下水的可渗透反应墙(PRB)介质。实验以铬污染地下水为研究对象,分别对Fe0、Fe0+石英砂和包覆型零价铁填料进行了筛选实验,选取处理效果好且经济可行的包覆型零价铁材料作为PRB反应介质。结果表明,以包覆型零价铁材料作为PRB反应介质,大大提高了铁粉的利用效率,且缓解了系统堵塞严重的问题。以包覆型零价铁材料作为PRB反应介质修复Cr(VI)污染地下水是可行的。The selection of the economical and efficient reactive media was studied on in-situ remediation of Cr（VI） contaminated groundwater by permeable reactive barrier （PRB） technology through experiment. With chromium-contaminated groundwater as the research subject, the Fe0,Fe0 mixed with sand and the iron wrapped with polymer were selected for PRB media testing. The effective and economical iron coated with polymer was selected as the PRB media. The experimental results indicate that the utilization efficiency of iron was raised greatly and the serious blockage problem was relieved. It is feasible to select the iron coated with polymer as the PRB media to remedy the Cr（VI） contaminated groundwater.
