摘要
膨润土是一种用途广泛的粘土岩,其主要成分蒙脱石具有独特的层间结构和优异的吸附性能,适合作为吸附材料应用于各种污水处理中。本文介绍了膨润土及其吸附的基本原理,探讨了近年来膨润土及改性后的膨润土应用于含重金属离子废水、有机废水、印染废水、含氨氮废水、含磷废水及其他废水中的研究现状。
Bentonite is a kind of widely used clay minerals,montmoduonite of its main composition with the unique interlayer structure and excellent adsorption performance,which suit for applying to deal with all kinds of wastewater as sorbent materials.Introducing the basic principles of adsorption of bentonite and discussing the bentonite and modified bentonite in wastewater containing heavy metal ions,organic wastewater,printing and dyeing wastewater,wast ewater containing ammonia nitrogen and phosphorus in the waste water and other wastewater research status in recent years.
