| 摘 要： | 膨润土来源丰富、价廉 ,且具有良好的吸附性能。采用不同的改性方法制得的改性膨润土 ,可显著提高其对各种有机物的吸附净化能力 ,有望成为新型的污水处理材料。其改性方法和应用研究正在成为热点。通过对膨润土的基本改性方法及改性膨润土在污水处理方面的应用进行总结 ,发现膨润土经改性后吸附能力可达原土的 1 0倍以上 ,能用于处理含有机物、重金属离子、离子型化合物等污染物的多类污水。

| Abstract: | Bentonite minerals are inexpensive, are obtained easily and have an excellent adsorption property. Modified bentonite got by different methods has a better ability of adsorption to absorb organic compounds and it is possible to become a new material in wastewater treatment .The modification of bentonite mineral and its application is a popular research subject. Through the summary of usual modification methods of bentonite and the application of modified bentonite to wastewater treatment, it can be concluded that modified bentonite has above the decuple adsorption ability than natural bentonite. Modified bentonite can be used to treat many kinds of wastewater, which contains organic compound, heavy metal ions, ionic compound etc. |
