摘　　要：室内试验采用溴化十六烷基三甲铵 (HDTMAB)制备改性沸石 ,研究了改性沸石处理印染废水的效果及影响因素 ,包括改性沸石的加入量、振荡时间、印染废液的pH值等 ,归纳出了改性沸石处理印染废水的最佳条件 ,发现改性沸石对印染废液的脱色率明显高于天然沸石 .结果表明 ,改性沸石对印染废水具有良好的处理效果 ,脱色率高于 90 % ,比天然沸石的脱色能力增大 2The zeolite modified with the cationic surfactant-hexadecyltrimethylammonuiumbromide (HDTMAB) was utilized for the decolorization of dying wasterwater. The main influential factors, such as quantity of modified zeolites added,mixing a ndshaking time,pH values of the dyeing wastewater which were investigated before the optimal conditions to sufficiently absorb dyes with the modified zeolites were summarized. The experimental results showed that the decolorization rates for modified zeolites to treat dyeing wastewater were over 90% which was 20 times higher than those for natural zeolites.
