用苄基二甲基十四烷基氯化铵(BAC)对天然膨润土进行改性,制得BAC-膨润土。用BAC-膨润土处理垃圾填埋场渗滤液,研究其去除垃圾渗滤液中CODCr和色度的影响因素及适宜条件。实验结果表明:BAC-膨润土对垃圾渗滤液中CODCr和色度的去除效果较之原土有显著提高,CODCr和色度的去除率可分别达到93.2%和96.9%。本研究为天然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。

Bentionite is modified with benzyldimethyltetradecylammonium chloride(BAC).Then BAC-bentonite is examined for its ability to remove.CODCr and color from landfill leachate.The result indicates that the efficiency of BAC-bentonite has been enhanced obviously..CODCrand color are removed by 93.2%and 96.9% resoectively.This research may provide caluale date for bentonite's modification and its application in treating landfill leachate.
