| 摘 要： | 用十六烷基三甲基溴化铵(CTMAB)改性膨润土,并用制备的有机改性膨润土处理垃圾渗滤液,研究其去除垃圾渗滤液中CODCr和色度的适宜条件。实验结果表明:有机改性膨润土对垃圾渗滤液中CODCr和色度的去除效果有显著提高;在适宜的实验条件下,CODCr和色度的去除率可分别达到86.7%和97.7%。本研究结果可为膨润土的改性及其在垃圾渗滤液处理中的应用提供有价值的参考数据。

| Abstract: | In this paper,bentonite was modified with cetyltrimthylammonium bromide(CTMAB).Then the organic modified-bentonite was examined for the ability to remove CODCr and color in landfill leachate.The results showed that the efficiency of the organic modified-bentonite has been improved obviously.CODCr and color can be removed by 86.7% and 97.7% respectively under appropriate conditions.This research can provide valuable data for bentonite's modifying and its application in treatment of landfill leachate. |
