摘要
论述了膨润土的类型、结构及其理化性质,介绍了利用膨润土的吸附性来处理废水中的重金属离子、有机废水、色度、氨氮的国内外研究现状。最后对其在废水处理方面进行了展望。膨润土作为一种新型吸附剂在水处理工艺中有着极为可观的应用前景。
The paper discussed the type,structure as well as physical and chemical properties of bentonite,introduced the method to removal heavy metal ions in wastewater,organic wastewater,chroma and NH3-N by modified bentonite in water treatment at home and abroad.Finally,it made a outlook in wastewater control.As a new sorbent bentonite has a extremely impressive application in the water treatment process.
