    Abstract
  • 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.
