摘要
蚀刻废液是对环境有较大危害的危险废物,同时又具有较高的资源型价值。目前江苏省每年蚀刻废液产生量较大,典型的含铜蚀刻废液产生量达数十万t,是江苏省产生量较大的几种危险废物类型之一。在调查了江苏省蚀刻废液处置利用的主要工艺和行业现状的基础上,分析了蚀刻废液处置利用过程存在的综合利用能力总体过剩、入厂分析制度不严、污染防治水平不高、再生产品管理标准缺失、环境管理制度不完善等问题;探讨了含铜蚀刻废液的再生产品使用过程中存在的生态环境风险;研究了蚀刻废液再利用产品中有害物质的控制要求;初步总结了行业发展中技术水平和管理要求的不足;提出了行业发展存在的问题,为下一步制定江苏省蚀刻废液处置利用行业的技术规范提供技术支撑。
Copper etching waste liquid is a kind of hazardous waste which has great harm to the environment,and also has high resource value.A large amount of etching waste is produced in Jiangsu Province every year,and typically the annual production of copper etching waste liquid reached hundreds of thousands of tons,which is one of the hazardous waste types with largest amounts.Based on the investigation of the main technologies and current situations of the disposal of the waste liquid in Jiangsu Province,several aspects of problems in the waste liquid treatment and utilization were analyzed,including the excessive capacity of comprehensive utilization,unstrict system of plant analysis,low level of pollution prevention and control,lack of standard for regeneration products management,and imperfect environmental management system.Besides,the environmental risks in the process of regeneration of copper containing etching waste liquor were discussed,and the control requirements of harmful substances in the regenerated products from the etching waste liquid analyzed.The existing problems in the development of the industry,such as insufficiencies of technical level and management requirements,were preliminary summarized,so as to provide technical support for formulating technical specifications on the treatment and utilization of etching waste liquid in Jiangsu Province.
