Membrane method treatment process for copper-containing wastewater generated in PCB (printed circuit board) production process
The invention discloses a membrane treatment process for copper-containing wastewater generated in a PCB (Printed Circuit Board) production process. Copper-containing wastewater generated in the production process of a printed circuit board (PCB) firstly passes through a multi-medium filter and a mechanical filter to remove large-particle suspended matters; then, pre-concentration is realized through a multi-stage nanofiltration system; finally, heavy metal ions in the wastewater are deeply concentrated and recycled through a multi-stage reverse osmosis system, and concentrated liquid can be used for electrolysis; the dialysate and the comprehensive wastewater pass through a multi-stage nanofiltration membrane together, and the permeate can reach the discharge standard. The process has the advantages of low resource consumption, less environmental pollution, good economic benefit and the like.
本发明公开了一种PCB生产过程中产生的含铜废水的膜法处理工艺。印刷电路板(PCB)生产过程中产生的含铜废水首先经过多介质过滤器+机械过滤器除去大颗粒悬浮物；然后经多级纳滤系统实现预浓缩；最后经多级反渗透系统深度浓缩回收其中的重金属离子，浓缩液可用于电解；透析液则与综合废水一起通过多级纳滤膜，透过液即可达到排放标准。该工艺具有资源消耗低、环境污染少、经济效益好等优势。
