The application of heavy metal waste water treatment and recycling technology is beneficial to environmental protection,saves resources and also brings great social and economical benefits.Now the traditional treatment processes,such as chemical precipitation,ion exchange,adsorption,biological and so on,can no longer meet the new discharge standard.The advanced JDL heavy metal waste water treatment and recycling technology can solve this problem well.It has many virtues,such as high efficiency,low consumption and good separation effect.In practical application to PCB waste water,the result show that the removal rate of Cu,Ni,Cr and Zn is above 99.6%,the content of Cu in recycled sludge can reach 55%~60%.For this technology can realize the real waste water reuse and heavy metal resource recycling,it must has important practical significance and broad application prospect.%重金属废水处理回用及重金属资源化回收技术的应用,有利于保护环境、节约资源、提高社会经济效益。化学沉法、离子交换法、吸附法、生物法等传统处理的方法已不能满足新标准的要求。金达莱公司成功开发新型JDL重金属废水资源化处理新技术工艺,研制出技术先进、高效低耗JDL处理器,固液分离功能强,效果好。实测表明,对线路板废水中的铜、镍、铬、锌等去除率可达到99.6%以上,回收的污泥中铜含量高达55%~60%。解决了重金属废水处理关键技术,实现了真正意义上的重金属废水处理回用和重金属资源化回收,技术值得推广应用。
