PCB企业含铜废水处理污泥技术研究

Study on the technology of treating sludge containing copper wastewater in PCB enterprise

印刷线路板(PCB)行业作为电子信息业的基础,随着电子产业的快速发展,对PCB的需求量也越来越多。但是PCB的生产过程中产生的大量酸性废水,废水污泥中含有铜的价值相对较高,如不加以回收利用,不仅危害环境,也将构成资源的浪费。本文依据本人真实项目实例,论述了PCB企业含铜废水处理污泥的技术研究,供同业人员参考。

Printed circuit board(PCB)industry as the basis of electronic information industry,with the rapid development of the electronics industry,the demand for PCB is also increasing.However,a large amount of acidic wastewater generated in the production of PCBs and wastewater containing copper are relatively high in value.If they are not recycled,they not only endanger the environment,but also constitute a waste of resources.Based on my real project example,this article discusses the PCB technology of copper-containing wastewater treatment of sludge for the reference of professionals.
