摘　　要：膨润土是以蒙脱石为主要矿物成分的非金属矿产,具有良好的膨润性、粘结性、吸附性、催化性、触变性、悬浮性以及阳离子交换性,对各种气体、液体、有机物质具有较强的吸附能力。随着新型膨润土技术的发展,具有高性能的改性膨润土在工业废水处理中将得到广泛应用。近年来,其在有机废水、无机废水、重金属废水等水处理方面的研究中已取得重大成果,本文总结了国内外相关的研究报道。Non-metallic mineral bentonite that montmorillonite is the main mineral composition, has a good swelling-property, cohesiveness, adsorption, catalysis, thixotropism and suspension and cation-exchange, and has a strong adsorbing ability to all kinds of gases, liquids, organic materials. With the development of new technology of bentonite, modified bentonite with high performance will be widely used in industrial wastewater treatment. In recent years, modified bentonite has made significant achievements in water treatment research of organic wastewater, inorganic wastewater and heavy metal wastewater, the reports of these aspects at home and abroad are summarized in this paper.
