| 摘 要： | 用溴代十六烷基吡啶对天然膨润土进行改性，制得CPB-膨润土，然后与Al2(SO4)，复合制得复合CPB-膨润土。研究复合CPB-膨润土去除垃圾渗滤液中CODCr和色度的适宜条件。实验结果表明：与原土比较，复合CPB-膨润土对垃圾渗滤液中CODCr和色度的去除效果有显著提高，CODCr和色度去除率分别可达到91．6％和95．2％。为膨润土的改性及其在垃圾渗滤液处理中的应用提供了有价值的参考数据。

| Abstract: | Bentonite was modified with cetyl pyridine bromide first, and then compounded with Al2(SO4)3 this paper. The compound CPB-bentonite was examined for its ability to remove COD and chroma in landfill leachate. The result indicated that the treatment effect of compound CPB-bentonite had been enhanced significantly. Under appropriate experimental condition, COD and chroma were removed by 91.6% and 95.2% respectively. This research provides valuable data for the modification of bentonite and its application in the treatment of landfill leachate. |
