摘　　要：膨润土是一种以蒙脱石为主要成分的优质吸附剂,在废水处理过程中有原料易得、成本低、吸附效果好等诸多优势。天然膨润土直接作为吸附剂使用存在亲水性强、吸附后固液分离困难等缺点,为改善其性能,需采用各种方法对其进行改性、复配。综述了近年来膨润土改性及膨润土复合吸附剂合成的各种方法,总结了改性膨润土及膨润土复合吸附剂在废水处理中的研究进展,旨在为确定改性膨润土及膨润土复合吸附剂今后发展方向提供思路。Bentonite is a kind of high-quality adsorbent with montmorillonite as the main component. In the process of wastewater treatment,bentonite has many advantages,such as easy access to raw materials,low cost and good adsorption effect. Natural bentonite used as adsorbent directly has the disadvantages of strong hydrophilicity and difficulty in solid-liquid separation after adsorption. In order to improve its performance,natural bentonite needs to be modified and compounded by various methods. Various methods of bentonite modification and synthesis of bentonite composite adsorbent in recent years were reviewed. The research progress of modified bentonite and bentonite composite adsorbent in wastewater treatment was summarized,aiming to provide ideas for the development direction of modified bentonite and bentonite composite adsorbent in the future.
