中国印制电路板行业每年产生大量含铜蚀刻废液,其资源化产品已在多行业广泛应用,如：碱式氯化铜用于饲料和工业、硫酸铜用于工业和电镀、碱式碳酸铜用于催化剂和木材防腐剂等。但行业技术混乱,标准缺失,导致处理工艺和产品质量参差不齐,存在极大的环境风险和资源浪费,标准化需求十分迫切。重点介绍了印制电路板含铜蚀刻废液资源综合利用工艺和产品现行标准和发展趋势。指出应制定相应标准、设置严格的技术要求、严控特征污染因子、控制产品质量、约束和规范行业行为,以促进中国电路板蚀刻废液行业治理和铜盐工业生产和应用技术发展,推动中国循环经济发展和无废城市建设。

In China’s printed circuit board industry,a large amount of copper-containing etching waste solution was produced every year,and its resource products have been widely used in many industries,such as basic copper chloride for feed and in-dustry,copper sulfate for industry and electroplating,basic copper carbonate for catalysts and wood preservatives,etc.Howev-er,the industry’s technical confusion and lack of standards have led to uneven of treatment process and products quality,which remains great environmental risks and waste of resources.The need to develop standards for industry is very urgent.The current standards and trends in the comprehensive utilization of resources and products from copper-containing etching waste solution of printed circuit boards were highlighted.By formulating corresponding standards,setting strict technical requirements,strictly controlling pollutants,controlling product quality,restraining and regulating industry behavior,the manage-ment of China’s circuit board etching waste solution industry and the development of copper salt production and application technology would be promoted,which would promote the development of China’s circular economy and waste-free cities.
