摘　　要：介绍了膨润土的结构性质;讨论了膨润土的改性方法,包括高温焙烧、酸化、盐活化和微波活化等活性改性法以及无机改性、有机改性和无机-有机复合改性等添加改性剂改性法。综述了改性膨润土在处理有机污染物、重金属离子污染物和印染废水等方面的应用。最后提出了改性膨润土目前存在的问题、发展方向和应用前景。Structural properties of bentonite were introduced. Methods for modification of bentonite, including activity modification such as high temperature calcining, acidification, salt activation and microwave activation as well as modification by additives such as inorganic additives, organic additives and inorganic/organic composite additives were discussed. Applications of modified bentonite in treatment of organic pollutants, heavy metal ion contaminants and the printing and dyeing waste water treatment et al were reviewed. Finally, existing problems, development trends and application outlook in the field of betonite modification were prospected.
