电镀污泥中有价金属综合回收技术研究现状

Research Status of Valuable Metals Recovery from Electroplating Sludge

随着我国经济的快速发展,电镀行业取得了巨大的进步,但同时也伴随着大量电镀废水的产生。电镀废水在处理过程中产生了大量固体危险废物—电镀污泥。该类污泥如果处理不当,则会引起二次环境污染,并对人体健康造成严重威胁。此外,由于污泥中含有大量有价金属,具有一定的回收价值,因此高效回收污泥中有价金属已成为目前的研究热点。本文全面阐述了电镀污泥中的有价金属的回收技术的研究现状,旨在为研究污泥资源化利用的企业和学者提供参考,结合自身实际生产和研究情况,提高污泥中有价金属的综合利用率。

With the rapid development of China's economy,electroplating industries have also made great progress.But it is also accompanied by a large number of electroplating wastewater.Electroplating wastewater produces a lot of solid hazardous waste-electroplating sludge in the treatment process.If not handled properly,it is going to cause secondary pollution and serious harm to human health.In addition,the reason why efficient recovery of valuable metals in sludge has become the focus of scholars is the sludge contains a large number of valuable metals and has a certain recovery value.In this paper,the research status of the recovery technologies of valuable metals in electroplating sludge is summarized.The purpose is to provide reference for the companies and scholars who study the resource utilization of sludge and to improve the comprehensive utilization radio of valuable metals in sludge combined with their own actual production situation.
