The ozone generator 3 is arranged on the right side of the treatment tank 1, and a hose 4 is fixedly connected to the left side of the ozone generator 3. A drain outlet 2 is arranged at the front end of the treatment tank 1. A top cover 11 is arranged at the top of the treatment tank 1. A fixing pipe 7 is arranged longitudinally through the top of the top of the top cover 11. A feed inlet 16 is fixedly connected to the left side of the top of the top of the top of the feed inlet 16. A first filter frame 17 is arranged inside the top of the top of the first filter frame 17. A sealing plate 18 is arranged at the top of the first filter frame 17. A second positioning block 19 is fixedly connected to the top of the feed inlet 16. A second locking nut 20 is movably connected to the outside of the second positioning block 19. Support seats 21 are fixedly connected to both sides inside the treatment tank 1. A positioning rod 22 is snapped into the top of the support seat 21. A support block 23 is fixedly connected to the outside of the positioning rod 22. A second filter frame 24 is arranged inside the treatment tank 1. A third filter frame 25 is arranged at the top of the second filter frame 24.

[0023] The third filter frame 25 is detachably sleeved on the outside of the top of the positioning rod 22, the second filter frame 24 is detachably sleeved on the bottom of the positioning rod 22, the sealing plate 18 is sleeved on the outside of the second positioning block 19, and the sealing plate 18 is detachably between the inlet 16 and the first filter frame 17 via the second locking nut 20.

[0024] A first connecting seat 12 is fixedly connected to the top of the outer side of the processing box 1. A first positioning block 14 is fixedly connected to the top of the first connecting seat 12. A second connecting seat 13 is fixedly connected to the bottom of the outer side of the top cover 11. The second connecting seat 13 is sleeved on the outside of the first positioning block 14. A first locking nut 15 is movably connected to the outside of the first positioning block 14. The top cover 11 is detachable from the first positioning block 14 through the first locking nut 15.

[0025] A screen is fixedly connected between the bottoms of the first filter frame 17, and the filter material of the second filter frame 24 and the third filter frame 25 is an ultrafiltration membrane.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, larger impurities can be pre-filtered using the first filter frame 17. When removing it, the first filter frame 17 can be directly taken out of the feed inlet 16 for cleaning. Afterwards, the wastewater passes through the second filter frame 24 and the third filter frame 25, and multiple filtrations can be performed through the double ultrafiltration membrane. When disassembly is required later, the third filter frame 25 is removed from the positioning rod 22, and then the positioning rod 22 is pulled out from the support base 21 to facilitate the removal of the second filter frame 25. This makes it easy to replace and disassemble after multiple filtrations, and is more suitable for use.

[0027] A three-way pipe 8 is fixedly installed at the top of the fixed pipe 7. A first valve 9 is fixedly installed on the outside of the right side of the three-way pipe 8. A second valve 10 is fixedly installed on the outside of the left side of the three-way pipe 8. The hose 4 is fixedly connected to the first valve 9.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, by utilizing the connection between the three-way pipe 8 and the fixed pipe 7, the first valve 9 can control the entry of ozone, and the second valve 10 can control the injection of clean water from the external water pipe, so that both ozone and clean water can be injected, which is convenient for rinsing the inner wall of the treatment tank 1 afterward.

[0029] A diversion pipe 26 is fixedly connected to the bottom of the fixed pipe 7. An annular pipe 5 is fixedly connected to the outside of the diversion pipe 26. A nozzle 6 is fixedly connected to the outside of the annular pipe 5. At least ten sets of nozzles 6 are provided, and the nozzles 6 are evenly distributed on the outside of the annular pipe 5.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, when the first valve 9 is opened, ozone can enter through the injection three-way pipe 8, then the fixed pipe 7, and then through the fixed pipe 7 and the diversion pipe 26 into the annular pipe 5. Finally, it is sprayed out through the equally spaced nozzles 6, which facilitates the uniform dispersion of ozone and allows it to fully contact the wastewater, thereby improving the sterilization quality.

[0031] Working Principle: In use, wastewater is first injected through the inlet 16. Larger impurities are pre-filtered using the first filter frame 17. Upon removal, the first filter frame 17 can be directly removed from the inlet 16 for cleaning. The wastewater then passes through the second filter frame 24 and the third filter frame 25, undergoing multiple filtrations via a double ultrafiltration membrane. Afterward, the first valve 9 is opened, allowing ozone to enter through the injection three-way pipe 8, then the fixed pipe 7, and finally the annular pipe 5 via the fixed pipe 7 and the diversion pipe 26. Finally, it is sprayed out through the evenly spaced nozzles 6, ensuring uniform ozone distribution. The ozone layer can fully contact the wastewater, improving the sterilization quality. After sterilization, it is discharged through the drain outlet 2. Connect the external water pipe to the second valve 10. Opening the second valve 10 can control the injection of clean water into the external water pipe, allowing both ozone and clean water to be injected. This facilitates rinsing the inner wall of the treatment tank 1. Finally, when it is necessary to disassemble the two sets of filter frames later, the top cover 11 can be opened, the third filter frame 25 can be removed from the positioning rod 22, and the positioning rod 22 can be pulled out from the support base 21 to facilitate the removal of the second filter frame 24. This makes it convenient to replace and disassemble after multiple filtrations.
