[0002] Electrocatalytic wastewater treatment utilizes an external electric field to drive pollutants in wastewater to undergo oxidation-reduction reactions on the electrode surface, thereby achieving efficient degradation and purification. To further improve wastewater treatment efficiency, patent 2022216843394 discloses a three-dimensional electrocatalytic oxidation device. This device constructs a three-dimensional electrode reaction system by setting particle electrodes within the reaction zone between the anode and cathode electrode plates, achieving efficient wastewater purification. However, as wastewater treatment progresses, pollutants accumulate on the particle electrode surface, reducing electrode activity. Therefore, regular cleaning of the particle electrodes is necessary; however, the aforementioned patent's particle electrode recovery and cleaning method is not very convenient. Summary of the Invention

[0004] Therefore, the present invention provides an electrocatalytic wastewater treatment device, comprising an electrochemical reaction tank, wherein a cathode plate and an anode plate are provided in the electrochemical reaction tank, and the cathode plate and the anode plate are respectively connected to a power source via wires. An insulating mesh frame is provided between the cathode plate and the anode plate in the electrochemical reaction tank, and a particle electrode is provided in the insulating mesh frame. A soaking treatment tank is provided on one side of the electrochemical reaction tank, and a cleaning solution is provided in the soaking treatment tank. A lifting and moving assembly is provided at the top of the reaction tank for lifting the insulating mesh frame out of the electrochemical reaction tank and moving it to the soaking treatment tank.

[0005] Specifically, the lifting and moving assembly includes a support beam, a slide rail disposed on the top of the support beam, a slider slidably disposed on the slide rail, a drive component for driving the slider to move, and a winch fixedly mounted on the slider. The winch has a hook on its hoisting rope, and the insulating mesh frame has a hanging point that cooperates with the hook.

[0006] Specifically, the driving component is a lead screw mechanism driven by a motor.

[0007] Specifically, the bottom of the electrochemical reaction tank is provided with a mesh partition, which divides the electrochemical reaction tank into an upper reaction chamber and a lower aeration chamber. The insulating mesh frame is placed directly on the mesh partition. An ozone aeration disc is provided in the aeration chamber, and the ozone aeration disc is connected to an external ozone generator through a pipe. The aeration chamber is provided with an inlet, and the upper side of the reaction chamber is provided with an outlet.

[0008] Specifically, the cleaning solution is deionized water.

[0009] Specifically, the power supply is connected to the cathode plate and the anode plate respectively via a pair of electrode clamps.

[0010] Compared with the prior art, this utility model has the following advantages: by setting particle electrodes between the anode plate and the cathode plate to form a three-dimensional electrode reaction system, efficient purification of wastewater can be achieved. At the same time, a lifting and moving component is set above the electrochemical reaction tank to confine the particle electrodes in an insulating mesh frame. When it is necessary to clean the particle electrodes, the lifting and moving component is used to lift the entire mesh frame out of the electrochemical reaction tank and move it to the soaking treatment tank. The cleaning solution in the soaking treatment tank is used to soak and treat the pollutants deposited on the surface of the particle electrodes, thus cleaning the particle electrodes. After the particle electrodes are cleaned, the lifting and moving component can be used to put the insulating mesh frame back into the electrochemical reaction tank, so that the wastewater can be electrochemically treated again.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] See Figure 1 An electrocatalytic wastewater treatment device includes an electrochemical reaction tank 1, a cathode plate 2 and an anode plate 3 in the electrochemical reaction tank 1, which are respectively connected to a power source 4 via wires. An insulating mesh frame 5 is provided between the cathode plate 2 and the anode plate 3 in the electrochemical reaction tank 1, and a particle electrode 6 is provided in the insulating mesh frame 5. A soaking treatment tank 7 is provided on one side of the electrochemical reaction tank 1, and a cleaning solution 8 is provided in the soaking treatment tank 7. A lifting and moving assembly is provided at the top of the reaction tank for lifting the insulating mesh frame 5 out of the electrochemical reaction tank and moving it to the soaking treatment tank 7.

[0018] In this embodiment, a three-dimensional electrode reaction system is formed by setting a particle electrode 6 between the anode plate 3 and the cathode plate 2, thereby achieving efficient purification of wastewater. At the same time, a lifting and moving component is set above the electrochemical reaction tank 1 to confine the particle electrode 6 in the insulating mesh frame 5. When it is necessary to clean the particle electrode 6, the lifting and moving component is used to lift the entire mesh frame out of the electrochemical reaction tank 1 and move it to the soaking treatment tank 7. The cleaning solution 8 in the soaking treatment tank 7 is used to soak and treat the pollutants deposited on the surface of the particle electrode 6, thereby cleaning the particle electrode 6. After the particle electrode 6 is cleaned, the lifting and moving component can be used to put the insulating mesh frame 5 back into the electrochemical reaction tank 1, so that the wastewater can be electrochemically treated again. The cleaning process of the particle electrode 6 is convenient and quick.

[0019] See Figure 1Specifically, the lifting and moving assembly includes a support beam 9, a slide rail 11 set on the top of the support beam 9, a slider 12 slidably set on the slide rail 11, a drive component 13 for driving the slider 12 to move, and a winch 14 fixedly installed on the slider 12. The winch 14 has a hook 15 on its hoisting rope, and the insulating mesh frame 5 has a hanging point 16 that cooperates with the hook 15.

[0020] When cleaning the insulating mesh frame 5 is required, the winch 14 is moved directly above the insulating mesh frame 5, the hook of the hoisting rope is connected to the hanging point 16, and the winch 14 is started to lift the insulating mesh frame 5 from the top of the reaction tank. Then, the drive unit 13 drives the slider 12 to move the insulating mesh frame 5 directly above the immersion treatment tank 7. After that, the winch 14 lowers the insulating mesh frame 5 into the immersion treatment tank 7 for immersion treatment. The cleaning solution 8 is used to immerse and clean the particle electrodes 6 inside the insulating mesh frame 5. After the particle electrodes 6 are cleaned, the insulating mesh frame 5 is hoisted back into the reaction tank. Because the particle electrodes 6 are confined within the insulating mesh frame 5, the recovery of the particle electrodes 6 during the cleaning process is convenient and quick. The particle electrodes 6 can be foam metal electrodes, activated carbon electrodes, etc. The mesh diameter of the insulating mesh frame 5 is smaller than that of the particle electrodes 6 to prevent the particle electrodes 6 from escaping. The cathode plate 2 and the anode plate 3 are made of corrosion-resistant titanium plates.

[0021] Understandably, the drive component 13 can be a screw mechanism driven by a motor, with the slider 12 threadedly connected to the screw of the screw mechanism. The motor is fixedly mounted on the support beam 9, and the motor shaft is fixedly connected to the screw via a coupling. Of course, the drive component 13 can also be a linear motor.

[0022] See Figure 1 In some embodiments, the bottom of the electrochemical reaction tank 1 is provided with a mesh partition 17, which has a number of through holes evenly distributed on it. The mesh partition 17 divides the electrochemical reaction tank 1 into an upper reaction chamber 18 and a lower aeration chamber 19. An insulating mesh frame 5 is placed directly on the mesh partition 17. An ozone aeration disc 20 is provided in the aeration chamber 19. The ozone aeration disc 20 is connected to an external ozone generator 21 through a pipe. The aeration chamber 19 is provided with an inlet, and the upper side of the reaction chamber 18 is provided with an outlet.

[0023] In this embodiment, ozone is introduced into the wastewater in the reaction tank through the ozone aeration disc 20, decomposing the recalcitrant organic matter in the wastewater into smaller organic molecules, improving the biodegradability of the wastewater, and further enhancing the purification effect. The mesh baffle 17 allows for uniform water inflow, ensuring the uniformity of the electrochemical reaction.

[0024] Specifically, the power supply 4 is connected to the cathode plate 2 and the anode plate 3 respectively through a pair of electrode clips. The power supply 4 is easy to assemble and disassemble from the electrode plates. The cleaning solution 8 can be deionized water. When immersing the electrode in deionized water, an appropriate amount of ionic strength regulator or inert electrolyte solution can be added to accelerate the recovery of the potential to the blank potential.

Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of the invention. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this invention.

[0026] Meanwhile, if the present invention discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding).
