[0002] Electroplating wastewater treatment ponds are facilities used to treat wastewater generated in the electroplating industry. Chemical agents and metal ions used in the electroplating process may enter the wastewater, causing serious environmental pollution. Therefore, it is very important to treat electroplating wastewater.

[0003] Currently, existing electroplating wastewater treatment tanks typically employ a stirring structure to agitate the wastewater during the reaction and precipitation process using chemicals. However, these stirring mechanisms are usually located in fixed positions, preventing the mixing of wastewater at different locations. This results in poor agitation and reduced mixing efficiency between the chemicals and wastewater. Furthermore, during wastewater treatment, dirt and impurities in the wastewater tend to adhere to the inner walls of the tank, making cleaning quite troublesome. Utility Model Content
