Product details
Phosphating and electroplating, as important pre-treatment processes for corrosion and rust prevention, are indispensable processes in multiple industrial fields, such as electronics, instrumentation, vehicles, electrical appliances, and others. But phosphating andelectroplating processThe wastewater generated during use not only contains a large amount of various organic pollutants such as polymer resins, surfactants, organic solvents, emulsified oils, but also phosphates, cyanides, acids, bases, as well as heavy metal pollutants such as hexavalent chromium, copper, zinc, nickel, cadmium, etc. Some of these heavy metal ions and cyanides are highly toxic substances that can cause cancer, deformity, and mutation. If discharged directly without treatment, they will cause great harm to the surrounding environment and human health. eyepreprocessingThe main methods for this type of wastewater include chemical methods, electrolysis methods, reverse osmosis methods, electrodialysis methods, activated carbon methods, biological methods, etc. A company in Chongqing specializes in specialized machinery, motorcycles (including engines)carEnterprises specializing in the production of Isuzu N series and P series light-duty vehicle front axles. The 17th workshop of the company is mainly responsible for the production of the company's productssurface treatmentWork. Perform phosphating and electroplating treatment on the product to meet production needs. Workshop 17 uses a large amount of strong acids, strong bases, phosphides, and heavy metals in the production process. Therefore, wastewater containing various heavy metals is generated every day, causing environmental pollution and endangering the health of people in surrounding areas. Strict treatment is necessary.
