Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a heavy metal ion wastewater treatment pool. Background Art

[0002] Heavy metal ion wastewater refers to industrial wastewater containing heavy metal ions or multiple heavy metal ions. These heavy metal ions usually come from industrial production processes such as mining, machinery manufacturing, chemical industry, electronics, instrumentation, etc., such as metal smelting, mineral processing, electronics manufacturing and chemical plants. Heavy metal ion wastewater is extremely harmful to the environment and human health, and effective treatment methods are needed; currently, there are many methods for treating heavy metal ion wastewater, including chemical precipitation, electrolysis, adsorption and membrane separation; among them, electrolysis refers to the conversion of electrical energy into chemical energy through an external power supply, using current to pass through metal electrodes in the electrolyte solution to cause redox reactions of heavy metal ions, thereby achieving the purpose of removing heavy metal ions.

[0003] The utility model patent with the authorization announcement number CN209974487U discloses a leather wastewater electrochemical oxidation treatment device, which includes a sedimentation tank and an electrochemical oxidation treatment tank, one side of the sedimentation tank is fixedly connected to the electrochemical oxidation treatment tank through a connecting pipe, a supercharger is fixedly installed on the top of the electrochemical oxidation treatment tank, the top of the inner cavity of the electrochemical oxidation treatment tank is fixedly inlaid with a positive electrode guide post, one side of the positive electrode guide post is fixedly inlaid with a negative electrode guide post, the current input ends of the positive electrode guide post and the negative electrode guide post are respectively connected to the current output end of the supercharger through a wire, and the inner cavity of the electrochemical oxidation treatment tank is fixedly connected with a circulating pump through a bracket. The wastewater in the electrochemical oxidation treatment tank is extracted by the circulating pump, and the movement speed of the wastewater is increased, so that the contact area between the wastewater and the positive and negative electrode guide posts can be effectively increased, and the supercharger can increase the voltage of the positive electrode guide post and the negative electrode guide post, so as to effectively improve the efficiency of electrochemical oxidation purification of wastewater, reduce energy loss, and use more energy-saving and environmentally friendly.

[0004] Although the electrochemical oxidation treatment device for leather wastewater effectively improves the efficiency of electrochemical oxidation purification of wastewater, the device still has the following problems in actual use: When using electrochemical methods to treat wastewater, the addition of electrolyte solution is an indispensable link. Electrolyte solution not only plays a key role in electrochemical reactions as the main medium for ion transfer, but its presence also directly affects the conductivity of wastewater, and has an important impact on the electrochemical treatment effect of heavy metal ion wastewater. However, the device is not equipped with a structure for adding electrolyte solution. Therefore, in actual operation, it is necessary to rely on manual methods to add electrolytes. This method is not only cumbersome to operate and increase the workload, but also has certain operational risks. It may affect the treatment effect due to improper operation and may even cause safety hazards. In view of this, we propose a heavy metal ion wastewater treatment pool. Utility Model Content
