摘　　要：膨润土在污水处理中的应用研究已经受到人们的广泛关注。膨润土在造纸废水、有机废水和重金属废水处理的应用研究中取得良好的效果,其中用添加助剂的膨润土处理造纸废水,COD去除率可达近80%;用阴-阳离子表面活性剂改性的膨润土成功地应用于有机废水处理;对于含重金属离子的废水的处理,膨润土也有很大的应用空间。总之,膨润土作为一种环境矿物材料研究还处于起步阶段,可以预见,随着对膨润土及其深加工产品开发,它在污水处理领域的应用将越来越广泛。The application study on wastewater treatment by bentonite has already received people＇s concern. It gets good results in treatment of papermaking wastewater, organic wastewater and heavy metal wastewater. The removal rate of COD is nearly 80% in papermaking wastewater when it was treated by bentonite with auxiliary. Bentonite, which was modified by anion - cation surface - active agent, is succeeded in applying to organic wastewater treatment. Bentonite is also used in the treatment of wastewater containing heavy metal ion. With the development of technology in environmental protection, bentonite will be widely used in wastewater treatment.
