Electrolytic copper foil is an important material widely used in electronics, communications, aerospace and other fields. In the production process of electrolytic copper foil, a large amount of wastewater will be generated, which contains a large amount of copper ions and other harmful substances, and if it is discharged directly, it will cause serious pollution to the environment. Therefore, the electrolytic copper foil water treatment process is of great significance for protecting the environment and improving the efficiency of resource utilization.
Electrolytic copper foil water treatment process.
Pretreatment. Pretreatment is the first link of electrolytic copper foil water treatment, which mainly includes grids, regulating tanks, sedimentation tanks and other equipment. Screens are used to remove large particulate matter from wastewater;Regulating tanks are used to regulate the quantity and quality of wastewater;Sedimentation tanks are used to remove suspended solids from wastewater.
Master processing. The main treatment is the core link of electrolytic copper foil water treatment, which mainly includes chemical precipitation method, adsorption method, membrane separation method and other methods. The chemical precipitation method mainly removes copper ions by adding chemical agents to react with the agents to generate precipitatesThe adsorption method mainly uses the adsorption of adsorbents to adsorb copper ions from wastewaterThe membrane separation method mainly separates copper ions from wastewater through reverse osmosis and other methods.
Post-processing. Post-treatment is the last process of electrolytic copper foil water treatment, which mainly includes disinfection, desalination and deodorization. Disinfection is mainly to kill bacteria and viruses in wastewater by adding chlorine and other disinfectants;Desalination is mainly through reverse osmosis and other methods to remove salts from wastewater;Deodorization is mainly to remove the odor in wastewater through activated carbon adsorption and other methods.
