[0032] 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.

[0033] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a wastewater deodorization device for wastewater treatment, comprising a tank 1 and a tank 2. A wastewater pipe 3 is fixedly connected to the left side of the tank 1, an inlet pipe 4 is fixedly connected to the front side of the tank 1, an outlet pipe 14 is fixedly connected to the bottom of the tank 1, an aeration pipe 2 is fixedly connected to the inner bottom of the tank 1, the input end of the aeration pipe 2 is fixedly connected to the left side of the tank 1, a connecting pipe 2 18 is fixedly connected to the right side of the tank 1, a connecting pipe 15 is fixedly connected to the left side of the tank 2, a one-way valve 16 is installed in the middle of the connecting pipe 15, an air pump 17 is installed between the connecting pipe 2 18 and the connecting pipe 1 15, a drain pipe 32 is fixedly connected to the bottom of the tank 2, an inlet pipe 10 is fixedly connected to the front side of the tank 2, and an exhaust pipe 33 is fixedly connected to the right side of the tank 2. First, wastewater is fed into tank 1 through wastewater pipe 3. Then, the chemical agent is fed into tank 1 through feed pipe 4 and mixed with the wastewater. Next, air is fed into the wastewater through an external vane pump connected to aeration pipe 2 to increase oxygen and improve dissolved oxygen concentration, thereby inhibiting the metabolic activity of anaerobic bacteria and reducing odor production. At the same time, the bubbles generated by aeration pipe 2 can increase the gas-liquid contact area and accelerate the transfer of odor from the liquid phase to the gas phase. After the gas rises, it is fed into connecting pipe 15 through air pump 17 via connecting pipe 2 18, and then into the dissolving liquid in tank 2 7 through connecting pipe 15. The dissolving liquid adsorbs and dissolves the substances in the odor. The gas purified by the dissolving liquid is discharged through exhaust pipe 33, thereby greatly improving the purification level of the gas. At the same time, a one-way valve 16 prevents the dissolved substances in tank 2 7 from entering connecting pipe 15.

[0034] Reference Figure 2A mixing assembly is installed in the middle of tank 1 and tank 7. The mixing assembly includes a fixing frame 5, which is fixedly connected to the top of tank 1. A motor 6 is installed in the middle of the fixing frame 5, and a stirring rod 13 is fixedly connected to the output end of the motor 6. A stirring rod 21 is rotatably connected to the middle of tank 7. A connecting assembly is installed between stirring rod 13 and stirring rod 21. The connecting assembly includes two pulleys 8, which are fixedly connected to the outer periphery of stirring rod 13 and stirring rod 21 respectively. A synchronous belt 9 is fitted around the outer periphery of each of the two pulleys 8. The drive motor 6 drives stirring rod 13 to rotate, so that stirring rod 13 can mix the sewage and deodorizing agent in tank 1, and at the same time fully mix the air input from the feed pipe 4 with the sewage. While stirring rod 13 is rotating, stirring rod 21 is driven to rotate together by the pulleys 8 and the synchronous belt 9, so that the gas input into tank 7 by air pump 17 can be dispersed by stirring rod 21 and fully mixed with the solution.

[0035] Reference Figures 3-5A shell 11 is fixedly connected to the right side of the canister 27. An activated carbon box 21 is slidably connected to the middle of the shell 11. A top rod 22 is fixedly connected to the top of the activated carbon box 21. A round rod 27 is rotatably connected to the middle of the shell 11. A limiting plate 19 is fixedly connected to the inner top of the shell 11. A support block 30 is fixedly connected to the other end of the limiting plate 19. A locking assembly is installed between the round rod 27 and the activated carbon box 21. A fixing block 24 is fixedly connected to the outer periphery of the round rod 27. A torsion spring 23 is fixedly connected to the top of the fixing block 24. The other end of the torsion spring 23 is fixedly connected to the inner top of the shell 11. A knob 1 is fixedly connected to the top of the round rod 27. 2. The engaging assembly includes a gear 20, which is fixedly connected to the outer periphery of the round rod 27. A rack 25 is slidably connected to the outer periphery of the limiting plate 19. The rack 25 meshes with the gear 20. The end of the rack 25 abuts against the top rod 22. A limiting groove 26 is opened in the middle of the rack 25. The limiting plate 19 is located in the middle of the limiting groove 26. The rack 25 is located at the top of the support block 30. A slot 28 is opened in the middle of the top rod 22. The rack 25 is slidably connected to the middle of the slot 28. Positioning plates 29 are fixedly connected to both the front and rear sides of the inner wall of the outer shell 11. The top rod 22 contacts the positioning plates 29. The exhaust pipe 33 is connected to the outer shell 11. After the gas is discharged through the exhaust pipe 33, the activated carbon box 21 adsorbs the insoluble impurities in the gas, thus ensuring that the gas does not cause secondary pollution when it is discharged. After a long period of filtration, turning the knob 12 drives the gear 20 to rotate, so that the gear 20 drives the rack 25 to slide out of the slot 28 on the top rod 22. At the same time, when the knob 12 drives the round rod 27 to rotate, it will drive the fixing block 24 to rotate together, so that the fixing block 24 torsion spring 23. After the activated carbon box 21 is inserted into the outer shell 11, the activated carbon box 21 is pushed to contact the top rod 22 with the positioning plate 29. After the knob 12 is released, the torsion spring 23 will drive the round rod 27 to reset, so that the gear 20 drives the rack 25 to insert into the slot 28, thus quickly disassembling and installing the activated carbon box 21, thereby ensuring the filtration effect of the activated carbon box 21.

[0036] Working principle: While adding chemicals to deodorize, air is introduced into the sewage through an external vane pump connected to aeration pipe 2, thereby increasing the dissolved oxygen concentration, inhibiting the metabolic activity of anaerobic bacteria, reducing the source of odor. At the same time, the air pump 17 carries the odor into tank 7, where the dissolved liquid adsorbs impurities in the dissolved gas. Simultaneously, with the connection of pulley 8 and synchronous belt 9, the fixed frame 5 drives the stirring rod 13 to rotate while mixing sewage and chemicals. The stirring rod 21 can also rotate together to break up the air bubbles, ensuring the mixing effect of odor and dissolved liquid. The purified gas is discharged through exhaust pipe 33, greatly improving the purification level of the gas.

[0037] The activated carbon box 21 purifies the gas to the maximum extent, thus avoiding secondary pollution to the environment. After long-term filtration, turning the knob 12 drives the gear 20 to rotate, causing the gear 20 to drive the rack 25 to slide out from the middle of the top rod 22. At the same time, when the knob 12 drives the round rod 27 to rotate, it will also drive the fixing block 24 to rotate, causing the fixing block 24 to torsion spring 23. After releasing the knob 12, the torsion spring 23 will drive the round rod 27 to return to its original position, thus quickly disassembling and installing the activated carbon box 21, thereby ensuring the filtration effect of the activated carbon box 21.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
