[0002] Electroplating is a process of decorating, protecting and obtaining certain new properties on the surface of metals and non-metals by using electrochemistry. In order to ensure the quality of electroplated products and make the metal coating have a smooth and good appearance, the attached liquid on the surface of the plated parts must be cleaned after plating; The traditional method is to place the electroplated products in a cleaning tank to clean the electroplated products. A large amount of wastewater will inevitably be generated during the cleaning process. The water quality and quantity of the wastewater are related to the process conditions, production load, operation management and water usage of electroplating production, such as Chinese patent application No. 201510120230.6, entitled "Electroplating heavy metal wastewater zero discharge recycling treatment process and special device thereof"; The water quality of electroplating wastewater is complex and generally contains heavy metal ions such as chromium, copper, nickel, zinc, gold, silver and cadmium. Therefore, the wastewater needs to be treated to remove heavy metal ions. After treatment, relatively clean water is formed. The clean water is stored in a water storage tank and used as water for cleaning electroplated products, which is then used again, fully utilizing water resources. However, the water is stored in the water storage tank for a long time, and scale, moss and other substances will form on the inner wall of the water storage tank. In order to keep the water in the water storage tank clean and ensure the cleaning effect of the electroplated products, the water storage tank needs to be cleaned regularly.
