[0002] During the copper sheet grinding process, some copper powder will be generated. These copper powders will be carried away by water during the washing process to form grinding plate wastewater. The discharge of copper-containing wastewater will cause harm to the environment and also cause waste of copper and water resources. The treatment system for copper sheet grinding wastewater in the existing technology has the disadvantages of low treatment efficiency and difficulty in effectively treating it to meet the standards. At the same time, in the treatment process, more flocculants, water treatment agents (such as PAM, PAC, etc.) need to be added.
