离子交换树脂处理电镀废水的技术研究现状与展望

Research status and Prospect of the ion exchange resin technology in the treatment of electroplating wastewater

本文综合阐述了离子交换树脂的类型,离子交换树脂对含氰、含铬、含金、含镍、含铜等电镀废水的处理研究现状,其对电镀废水具有吸附效率高,可再生重复利用等优点,但也发现应用过程中存在树脂破碎、树脂中毒、树脂板结等问题。因此需要对离子交换树脂进行更深入研究才能提升其在电镀废水处理中的应用。

The types of ion exchange resins are described in this paper. The present research situation of the treatment by ion exchange resin of electroplating wastewater which including cyanide, chromium , gold, nickel, copper. Ion exchange resin has the advantages of high adsorption efficiency, renewable recycling and so on. There are many problems such as resin harden, poisoning, broken. Therefore, it is necessary to conduct a more in - depth study of the ion exchange resin in order to improve its application in electroplating wastewater treatment.
