The conductive column 502 clamps the electrode plate 21 through the fixing mechanism 11, and a sealing gasket 12 is fixedly connected to the opening of the through hole 10; the middle part of the electrolytic cell 3 also includes a porous diaphragm, which can separate the anode area and the cathode area according to the performance of the corresponding electrode material in the electrolytic cell 3. The inside of the fuselage 2 also includes an ion generator, and the positive and negative wires of the ion generator are connected to the electrical connector 501 of the corresponding anode area and cathode area. A water pump is also provided on the inside of the fuselage 2, and the input end of the water pump is connected to the electrolytic cell 3 through a water pipe. The basic operating principle of this technical solution is the same as that of a diaphragm electrolysis heavy metal wastewater treatment device disclosed in announcement number CN208898563U. Its principle is: connect the control panel to the external power supply, and then use the ion generator to generate negative ions and release them into the heavy metal wastewater in the electrolytic cell 3. The anode area and the cathode area in the electrolytic cell 3 are separated by a porous diaphragm, so that the electrolysis products of the heavy metal wastewater at the anode area and the cathode area are separated and collected separately. Then, the temperature information and ion information of the heavy metal wastewater in the electrolytic cell 3 are observed by the temperature sensor and the ion concentration sensor and transmitted to the control panel, so that it can be used for a long time. During use, temperature and ionization deviations occur so that expected adjustments can be made.

Finally, the user effectively cleans up the macromolecular chelate after flocculation in the heavy metal wastewater in the electrolytic cell 3, which can effectively reduce the heavy metal ions in the wastewater and greatly reduce the pollutants in the heavy metal wastewater.
