【摘要】 膨润土是一种由蒙脱石构成的粘土矿物,广泛地应用于工业、农业和其他领域。目前膨润土已开始应用于废水处理中,但是未经改性的膨润土对去除废水中有机物和脱色效果较差,故一般用于废水处理的膨润土都要经过改性,增大其比表面积,提高吸附能力。对国内外膨润土在废水处理领域的应用及研究现状、改性方法、活化方法等做了概述,并展望了其应用前景。更多还原

【Abstract】 Bentonite is a kind of clay mineral consisting of montmorillonite and is widely used in industry,angri-culture and other fields.At present bentonite has come into use in waste water treatment.But the unmodified ben-tonite has low efficiency of wastewater treatment ,so most of bentonite applied to wastewater treatment is modified to increase it’s surface area and capacity of adsorption.The present condition s of bentonite and modified ben-tonite in China and abroad are studied,the methods of modification and activation are investigated also.At the end the applied foreground of bentonite and modified bentonite are prospected.更多还原
