摘要
论述了膨润土的吸附机理,介绍了膨润土的物理及化学改性方法及其对有机染料废水,焦化废水,烟草废水,煤泥水,含酚类、石油烃类、抗生素废水及微污染水等的处理效果。针对膨润土作为环保吸附剂存在的问题指出了今后的研究方向:1)将研究成果应用于实际废水;2)研究环境友好且效果好的改性工艺及材料;3)研究新的吸附剂制备形式;4)加大膨润土在废气处理上的研究力度;5)研制吸附效果更佳且能处理复杂成分污水的新型复合吸附剂。
The adsorption mechanism of bentonite is discussed. The physical and chemical methods for bentonite modification are introduced. And the effects of bentonite on wastewater treatment are discussed,such as：organic dye wastewater,coking wastewater,tobacco wastewater,coal slime water,phenol-,oil-and antibiotic-containing wastewater,micro-polluted water,and so on. Aiming at the problems of bentonite used as adsorbent for environmental protection,the directions for future research are prospected as follows：1）applying research results to actual wastewater;2）developing environmentally friendly and effective modified processes and materials;3）preparing new forms of absorbent;4）promoting research on waste gas treatment with bentonite;5）developing new composite adsorbents with better adsorption effect and treatment ability to wastewater containing complex components.
