[0002] Electroplating wastewater refers to wastewater containing heavy metal ions, acids and alkalis, and other harmful substances generated during the electroplating process. Electroplating is a process of depositing metals or alloys on the surface of an object through electrolysis. It is widely used in metal surface treatment, decoration, and anti-corrosion. The main components are heavy metals, acids and alkalis, organic matter, and suspended matter. These wastewaters will pollute water bodies, soil, and ecosystems, affect water quality, and endanger biological health. The management and treatment of electroplating wastewater are crucial, which can not only protect the environment but also promote the recycling of resources. Therefore, it is very important to treat electroplating wastewater.

The cooled water can be reused.
