摘    要:膨润土是一种以蒙脱石为主要矿物的粘土岩,应用广泛,目前已越来越多的应用于废水处理中,但未经处理的膨润土吸附脱色的性能较差,故一般用于废水处理的膨润土往往要经过一次或两次改性处理,以增大其比表面积,改善其吸附能力,常用的改性方法有两种:活化法,添加改进剂法,改性膨润土具有吸附脱色性能优良,废水处理效果好等特点,从而扩大了其应用范围。

关 键 词:膨润土  改性  有机废水处理  改进剂  吸附性能  活化法  脱色性能

Abstract:The bentonite is a kind of clay mineral mainly consisted of montmorillonite, and it has been used widely in wastewater treatment. But the untreated bentonite has poor quality of adsorption and decolorization. So the bentonite used in wastewater treatment is usually modified to expand its special surface, improve its ability of adsorption. Many scholar has made large research work about it, the usual used methods is activation and adding modifier. The modified bentonite has better qualities and ability of wastewater treatment, thus enlarge its applying scope.
Keywords:bentonite  activize  modify  organic wastewater treatment
