Electroplating is a technique that deposits metal onto the surface of a substrate through electrolysis to enhance durability, corrosion resistance, and appearance. It is widely used in electronics, machinery, and other fields. However, the electroplating process involves heavy metals (such as chromium, nickel, and copper) and chemicals, which, when discharged with wastewater, can lead to environmental pollution, especially under increasingly stringent discharge standards. Therefore, the electroplating industry must address challenges in wastewater treatment, including heavy metal removal, pH control, and water reuse, and ensure proper chemical management and disposal to minimize environmental impact.
