[0022] 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.

[0023] Please see Figures 1-4This utility model relates to an electrochemical degradation device for antibiotic wastewater, comprising a reaction tank 1, an electrolytic cell 2 inside the reaction tank 1, an anode plate 20 and a cathode plate 21 on the electrolytic cell 2, a feeding mechanism and a mounting box 3 at the top of the reaction tank 1, a discharge mechanism at the bottom of the reaction tank 1, a threaded groove at the top of the mounting box 3, a threaded post 4 on the threaded groove, and an annular groove 5 on the threaded post 4, a fastening box 6 on one side of the mounting box 3, a fastening hole between the fastening box 6 and the threaded groove, a fastening post 7 on the fastening hole, an elastic support mechanism between the fastening post 7 and the fastening hole, and the fastening post 7 abutting against the annular groove 5. A heater 8 is provided at the top of the mounting box 3, and a heating tube 9 is provided on the heater 8. An adjustment groove is opened inside the mounting box 3, and the heating tube 9 passes through the adjustment groove and extends into the electrolytic cell 2. A sealing bearing 10 is provided between the adjustment groove and the heating tube 9. A sealing cylinder 11 is provided between the outer side of the sealing bearing 10 and the electrolytic cell 2. The heating tube 9 is located inside the sealing cylinder 11. An adjustment gear 12 is provided at the top of the sealing cylinder 11. A drive motor 13 is provided at the top of the threaded column 4. The output end of the drive motor 13 extends into the adjustment groove and is provided with a drive bevel gear 14. The drive bevel gear 14 meshes with the adjustment gear 12. A stirring assembly 15 is provided on the sealing cylinder 11. In this embodiment, wastewater and pH adjusting agent are supplied through a feeding mechanism. Then, the heating tube 9 is heated by the heater 8, thereby raising the temperature of the wastewater in the electrolytic cell 2. This increases the temperature of the wastewater, facilitating the electrochemical degradation of antibiotics. Typically, the optimal temperature range for electrochemical antibiotic degradation is between 25°C and 40°C. Pulling the fastening column 7 disengages one end of it from the threaded groove. Then, the threaded column 4 is threaded into the threaded groove, causing the drive bevel gear 14 at the output of the drive motor 13 to mesh with the adjusting gear 12. At this point, the threaded column 4 rests against the threaded groove, and the fastening column 7 aligns with the annular groove 5 of the threaded column 4. Loosening the fastening column 7 allows the elastic support mechanism to provide elastic support. One end of the threaded post 4 is pressed against the annular groove 5 to ensure a secure assembly. Then, the output end of the drive motor 13 drives the drive bevel gear 14 to rotate, which in turn drives the adjusting gear 12 to rotate. The adjusting gear 12 stabilizes the rotation angle through the sealed bearing 10, and the adjusting gear 12 drives the sealing cylinder 11 to rotate. The sealing cylinder 11 provides protection for the heater 8, and the stirring assembly 15 of the sealing cylinder 11 can stir the wastewater, thereby improving the wastewater degradation efficiency. Strong oxidants such as ·OH free radicals are generated at the anode of the anode plate 20. These strong oxidants can non-selectively oxidize organic matter in the water, including antibiotics. At the same time, the hydrogen gas generated at the cathode of the cathode plate 21 helps to destroy the molecular structure of some antibiotics.Heating, stirring, and the use of anode plate 20 and cathode plate 21 can improve antibiotic removal efficiency. Wastewater can be discharged using a discharge mechanism. By pulling the fastening column 7, the elastic support mechanism is compressed and deformed, causing one end of the fastening column 7 to leave the annular groove 5. Rotating the threaded column 4 allows the drive motor 13 to be removed for easy maintenance.

[0024] In this scheme, the feeding mechanism includes a feeding pipe 16, which is installed at the top of the reaction tank 1 and connected to the electrolytic cell 2. Multiple feeding pipes 16 are provided, and multiple feeding pipes 16 can facilitate the supply of pH adjustment agent and wastewater.

[0025] In this scheme, the discharge mechanism includes a discharge pipe 17, which is installed at the bottom of the reaction tank 1 and extends fully to one side. The discharge pipe 17 is equipped with a valve. By closing the valve, the antibiotic wastewater in the electrolytic cell 2 can be easily discharged for degradation reaction. By opening the valve, the degraded wastewater can be easily discharged.

[0026] In this solution, the elastic support mechanism includes a fastening groove, which is formed on one side of the fastening hole. A fastening plate 18 is provided on the fastening groove, and the fastening plate 18 is connected to the fastening post 7. An elastic component 19 is provided between the fastening plate 18 and the fastening groove. The fastening plate 18 is elastically supported by the elastic component 19 in the fastening groove, and the fastening plate 18 drives the fastening post 7 to move, so that the elastic component 19 provides elastic support for the fastening post 7, ensuring that one end of the fastening post 7 abuts against the annular groove 5.

[0027] In this solution, both the feed pipe 16 and the discharge pipe 17 are equipped with flanges, which facilitate the connection of external pipes to the feed pipe 16 and the discharge pipe 17.

[0028] In this solution, the valve is an electric valve, which allows for easy remote operation and switching.

[0029] In this solution, the drive motor 13 is a servo motor, which has the characteristic of high rotational accuracy, thereby improving the rotational accuracy of the drive motor 13.

[0030] In this design, one end of the fastening post 7 is provided with an arc groove, which matches the annular groove 5. By matching the arc groove with the annular groove 5, the fastening post 7 can be stably pressed against the annular groove 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
