离子交换树脂处理重金属废水的研究进展

Application and Progress of Ion Exchange Resins in Treatment of Wastewater

当前重金属废水排放形势日益严峻,废水处理技术也在不断的更新,离子交换树脂的方法得到较广泛的关注和应用,综述主要介绍了离子交换树脂的分离机理和简单工艺技术及其在重金属废水处理方面的研究和应用,介绍了近年来国内外采用离子交换树脂处理重金属废水的研究发展和研究成果,并针对该技术方法研究方向提出一些看法。

As current increasingly grim situation of heavy metal wastewater discharge, wastewater treatment technologies were constantly updated. The method of ion -exchange separation mechanism and application in the extraction resin was more widely used. Ion - exchange resins including their process from wastewater in resent years were briefly introduced. The progress of research in treatment was introduced and analyzed as well as the existed problems. Some advices and emphases in the field of research especially for the application of ion - exchange resins were put forward.
