摘　　要：随着智能化行业的发展,印刷线路板(PCB)的需求量越来越大。其中,被广泛应用于PCB行业的蚀刻液随之而然会产生大量蚀刻废液,若不进行有效处理而直接排放必然会对环境造成污染。而蚀刻废液里含有大量的金属铜和氯离子,运用先进工艺可从中回收有价金属铜,并降低氯离子浓度,从而使蚀刻废液达标排放或循环利用。本文从工艺、辅料、设备等方面对含铜蚀刻废液工业处理工艺进行对比和研究。The demand of PCB is increasing for the development of intelligent industry.Etching solution is widely used in PCB industry.A large number of etching waste liquid will be produced by the development of intelligent industry technology.It will cause environmental pollution if not treated.The etching waste liquid contains a large number of copper and chloride ions.If we use advanced technology,the copper can be recovered and the concentration of chloride can be reduced,so that the waste liquid can be discharged.The industrial treatment technology of waste liquid containing copper is studied from the technology,auxiliary materials and equipment in this paper.
