摘要： 为了研究PRB技术修复垃圾渗滤液污染地下水的可能性，筛选最佳反应介质及其配比，为城市垃圾渗滤液污染地下水的治理提供参考，选择零价铁粉、膨润土、沸石、活性碳、炉渣5种反应介质，研究其对垃圾渗滤液污染地下水的治理效果。结果表明：5种反应介质单独作用下，活性炭对地下水中的COD去除效果最好，去除率达到76.0%，沸石对COD去除效果最差，去除率仅为45.0%，但沸石对地下水中NH3的去除效果最好，去除率为70.8%，零价铁对NH3的去除效果最差，去除率为42.3%；选择零价铁、活性炭、沸石3种介质按照不同配比继续试验，得出对COD的去除效果以零价铁：活性炭：沸石= 2:2:1的比例最好，其次是1:2:2和2:1:2，对NH3的去除效果以零价铁：活性炭：沸石=1:2:2的比例最好，其次是2:1:2和2:2:1。

Abstract: In order to research the possibility of repairation of groundwater polluted by landfill leachate by PRB, the author researched on treatment on groundwater polluted by landfill leachate using zero-valent iron, bentonite, zeolite, activated carbon and slag. The results showed that: treatment to COD with activated carbon was the best, which the removal rate reached to 76.0%. Treatment to COD with zeolite was the worst, which the removal rate was only 45.0% . However, treatment to NH 3 with zeolite was the best, which the removal rate reached to 70.8% . Treatment to NH 3 with zero- valent iron was the worst, which the removal rate was only 42.3%. Experiment continued with zero valent iron, activated carbon and zeolite in different proportioning. It concluded that treatment to COD with zero valent iron, activated carbon and zeolite in 2:2:1 was the best, and then was 1:2:2 and 2:1:2. Treatment to NH 3 with zero valent iron, activated carbon and zeolite in 1:2:1 was the best, and then was 2:1:2 and 2:2:1.
