[0023] The utility model provides a device for treating odor in a sewage treatment plant. Figure 1-5As shown, the odor control device of the sewage treatment plant includes: a plurality of baffles 1 hinged on the ground, and the plurality of baffles 1 are combined to surround the outside of the sewage pool; a plurality of cover plates 2, and the plurality of cover plates 2 are respectively hinged on the tops of the plurality of baffles 1; a water tank 3, the water tank 3 is arranged on one side of the sewage pool and located between the plurality of baffles 1, and the water tank 3 is filled with a microbial deodorant; a connecting hose 4, the connecting hose 4 is installed on the water tank 3, and the liquid inlet end of the connecting hose 4 is fixed with a water pump located in the water tank 3; a fixed pipe 5, the fixed pipe 5 is fixedly installed at the liquid discharge end of the connecting hose 4, and the fixed pipe 5 is provided with a plurality of spray heads 6; a water separation component, the water separation component is arranged in the sewage pool and connected to the fixed pipe 5, and the water separation component is used for mixing liquids.

[0024] In this embodiment, the baffles 1 surround the sewage pool to form a closable enclosure structure. They can be flexibly opened and closed through a hinged design, which is convenient for daily maintenance and cleaning of the sewage pool. At the same time, the closed structure can effectively prevent the odor in the sewage from escaping into the external environment. Multiple cover plates 2 and the baffles 1 together constitute a complete closed system. The presence of the cover plates 2 further enhances the odor barrier effect, and also helps to prevent external substances and organisms from entering the sewage pool, thereby ensuring the safety of sewage treatment. The provision of the water tank 3 makes the storage and addition of the agent more convenient and centralized. The water pump is used to extract the microbial deodorant from the water tank 3 and transport it to the sewage pool through the connecting hose 4. This design realizes the automatic addition of the agent and improves the treatment efficiency. When the water pump is working, the microbial deodorant is pumped into the fixed pipe 5 and evenly sprayed into the sewage pool through the spray head 6.

[0025] In a further preferred embodiment of the utility model, the water diversion assembly includes two mounting plates 7, a filter frame 8, a plurality of isolation rods 9 and two adjustment plates 10, the two mounting plates 7 are installed in the sewage pool by bolts, the filter frame 8 is fixedly installed between the two mounting plates 7, the plurality of isolation rods 9 are fixedly installed in the filter frame 8, the two adjustment plates 10 are detachably installed on both sides of the filter frame 8, the two adjustment plates 10 are respectively in contact with the inner walls on both sides of the sewage pool, and the fixed pipe 5 is fixedly connected to the filter frame 8.

[0026] In this embodiment, the mounting plates 7 serve as the supporting base of the water diversion assembly, which ensures the stability and reliability of the water diversion assembly so that the water diversion assembly can be firmly installed in the sewage pool. The filter frame 8 is the main part of the water diversion assembly, but can effectively disperse the agent and sewage so that the agent can be evenly distributed in the sewage pool. The function of these isolation rods 9 is to divide the space inside the filter frame 8 into a plurality of small blocks. Such a design is conducive to further dispersion and refinement of the agent when passing through the filter frame 8, so that it can be more evenly mixed into the sewage. The design of the adjustment plate 10 allows adjustment according to the actual size of the sewage pool to ensure that the water diversion assembly can fit tightly against the inner wall of the sewage pool, thereby preventing the agent from overflowing from both sides of the filter frame 8.

[0027] In a further preferred embodiment of the utility model, electric telescopic rods 11 are fixedly installed on both sides of the filter frame 8, and the same isolation plate 12 is fixedly installed on the output rods of the two electric telescopic rods 11, and the isolation plate 12 can contact the filter frame 8, and the two electric telescopic rods 11 are fixedly covered with rubber protective sleeves 13.

[0028] In this embodiment, the electric telescopic rod 11 has an adjustable length function and can adjust the length of its output rod according to actual needs. When the electric telescopic rod 11 is shortened, the isolation plate 12 will be close to the filter frame 8, thereby closing the opening of the filter frame 8, so that the sewage flow rate can be adjusted. The role of the rubber protective sleeve 13 is to protect the electric telescopic rod 11 from erosion by the external environment, such as chemicals in sewage or physical impact, thereby extending the service life of the electric telescopic rod 11.

[0029] In a further preferred embodiment of the utility model, a suspension board 14 is placed in the water tank 3, two limit rods 16 are fixedly installed on the top of the suspension board 14, and the top of the two limit rods 16 are fixed with the same top cover 17, and an infrared rangefinder 18 is installed at the bottom of any one of the cover plates 2, and the infrared rangefinder 18 is located on the top of the top cover 17.

[0030] In this embodiment, the floating plate 14 has buoyancy and can float up and down as the water level in the water tank 3 changes, so as to always remain near the water surface. Such a design is conducive to reflecting the water level in the water tank 3 in real time. When the floating plate 14 rises with the water level, the top cover 17 will also rise accordingly. When the water level drops, the top cover 17 will drop accordingly. Therefore, the height of the top cover 17 can reflect the water level in the water tank 3 in real time. The infrared rangefinder 18 can accurately judge the water level in the water tank 3 by measuring the distance between it and the top cover 17. This non-contact measurement method is not only accurate and reliable, but also can reflect the changes in the water level in real time.

[0031] In a further preferred embodiment of the utility model, a liquid replenishing pipe is installed on one side of the water tank 3, a one-way valve is provided on the liquid replenishing pipe, and the liquid replenishing pipe is connected to a container storing a microbial deodorant.

[0032] In this embodiment, the function of the refilling tube is to replenish the microbial deodorizing agent into the water tank 3. When the agent in the water tank 3 is reduced to a certain amount, the agent can be transported from the storage container to the water tank 3 through the refilling tube to ensure an adequate supply of the agent. The function of the one-way valve is to prevent the agent from flowing back into the storage container during the transportation process. By connecting the refilling tube and the storage container, automatic replenishment of the agent can be achieved. When the agent in the water tank 3 is reduced, the agent can be automatically replenished from the storage container without manual operation, thereby improving the continuity and efficiency of the treatment. By replenishing the agent in time, it can be ensured that the odor in the sewage is continuously and effectively treated, thereby improving the treatment effect.

[0033] In a further preferred embodiment of the present invention, limit plates 15 are fixedly mounted on the inner walls of both sides of the water tank 3 , and the two limit plates 15 are movably sleeved outside the two limit rods 16 .

[0034] In this embodiment, the limit plate 15 is designed to limit the vertical movement range of the suspension board 14, ensuring that the suspension board 14 and the limit rod 16 thereon float freely within the set range, allowing the suspension board 14 to float up and down with the change of the water level in the water tank 3, while ensuring that it does not deviate from the set range.

[0035] In a further preferred embodiment of the utility model, any one of the baffles 1 is provided with an observation window, the plurality of isolation rods 9 are all U-shaped, and connecting rods are fixedly installed outside the plurality of baffles 1, and the plurality of connecting rods can be connected to each other by bolts.

[0036] In this embodiment, the setting of the observation window allows the user to directly observe the sewage situation behind the baffle 1 from the outside without frequently opening the baffle 1 for inspection, thereby improving the convenience and safety of operation. The cooperation of the connecting rod and the bolt allows the user to connect different numbers of baffles 1 according to actual needs to adapt to sewage pools of different sizes or different treatment needs, thereby improving the flexibility and adaptability of the device.

[0037] In summary, compared with the related art, the present device stores microbial deodorizing agents in a water tank 3 to facilitate the addition of agents, and can divert sewage flow by setting a water diversion component to further mix the microbial deodorizing agents and sewage. The water pool can be closed by setting a plurality of baffles 1 in cooperation with the cover plate 2 to prevent odor from escaping, and the baffle 1 can be made to contact the ground by adjusting the angle of the baffle 1, thereby exposing the sewage pool and facilitating the maintenance of the sewage pool.
