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.
