[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] As Figure 1 and Figure 2 shown, a deodorization device for sewage treatment is disclosed in this embodiment, including: a sewage treatment device 1, a deodorant spraying device 2, an odor treatment device 3, a water inlet 4, and a drain outlet 5.

[0023] The sewage treatment device 1 includes a housing 1-3, a stirring device 1-1 is arranged on the housing 1-3, and an aeration device 1-2 is arranged at the bottom inside the housing 1-3.

[0024] The stirring device 1-1 includes a rotating shaft 1-1-2, the rotating shaft 1-1-2 is arranged in the housing 1-3, a plurality of perforated stirring blades 1-1-3 are arranged on the rotating shaft 1-1-2, the rotating shaft 1-1-2 is power-connected to a motor 1-1-1, and the motor 1-1-1 is arranged on the outer wall of the housing 1-3. The rotation of the motor 1-1-1 drives the rotation of the rotating shaft 1-1-2, and further drives the stirring blade 1-1-3 to rotate and stir.

[0025] The aeration device 1-2 includes an aeration head 1-2-2, the aeration head 1-2-2 is arranged at the bottom inside the housing 1-3, the aeration head 1-2-2 is connected to an air pump 1-2-1 through a pipeline, and the air pump 1-2-1 is arranged on the outer wall of the housing 1-3. The aeration head 1-2-2 aerates at the bottom, adding gas to the water body. At the same time, the holes on the rotating stirring blade 1-1-3 can make the mixing of the agent, water body and gas more sufficient, and can break up the bubbles of the aeration head 1-2-2, making them more finely integrated into the water body, thereby increasing the contact area between the agent and the water body, making the reaction more sufficient and improving the deodorization effect.

[0026] The deodorizing spraying device 2 includes a deodorizing agent tank 2-1, which is arranged at the top of the housing 1-3. A first pump 2-2 and a second pump 2-4 are connected to the lower part of the deodorizing agent tank 2-1 through pipelines. The first pump 2-2 is connected to a spray head 2-3 through a pipeline, and the spray head 2-3 is arranged above the stirring device 1-1 inside the housing 1-3. The second pump 2-4 is connected to an atomizing nozzle 2-5 through a pipeline, and the atomizing nozzle 2-5 is arranged inside the odor treatment device 3. Starting the first pump 2-2 can spray the deodorizing agent into the housing 1-3 through the spray head 2-3, and starting the second pump 2-4 can spray the atomized deodorizing agent into the deodorizing chamber 3-3 through the atomizing nozzle 2-5.

[0027] The odor treatment device 3 includes a deodorizing chamber 3-3, which is communicated with the housing 1-3 through an air inlet pipe 3-2. An induced draft fan 3-1 is arranged on the air inlet pipe 3-2. One side of the deodorizing chamber 3-3 away from the air inlet pipe 3-2 is communicated with the housing 1-3 through a return pipe 3-7. An activated carbon plate 3-5 is arranged near the return pipe 3-7 inside the deodorizing chamber 3-3. A plurality of adsorption plates 3-4 are arranged between the activated carbon plate 3-5 and the air inlet pipe 3-2 inside the deodorizing chamber 3-3. The adsorption plates 3-4 are arranged below the atomizing nozzle 2-5. The adsorption plates 3-4 are of a perforated plate structure with a plurality of fine holes. When the atomizing nozzle 2-5 sprays the deodorizing agent, the atomized deodorizing agent will be adsorbed on the adsorption plates 3-4, increasing the reaction time between the atomized deodorizing agent and the odor, and improving the deodorizing efficiency.

[0028] The bottom plate of the deodorizing chamber 3-3 is provided with an inclination angle inclined towards the return pipe 3-7. A valve 3-8 is arranged on the return pipe 3-7.

In addition, it can also play a role in balancing the air pressure inside the device when the induced draft fan is working. An exhaust pipe 3-6 is arranged on the side wall of the deodorizing chamber 3-3.

[0029] The induced draft fan 3-1 is used to introduce the odor in the sewage treatment device 1 into the deodorizing chamber 3-3 through the air inlet pipe 3-2, where it reacts with the atomized deodorizing agent sprayed by the atomizing nozzle 2-5 and the deodorizing agent adsorbed on the adsorption plates 3-4 for deodorization. Then, it is further adsorbed and deodorized by passing through the activated carbon plate 3-5, and finally discharged through the exhaust pipe 3-6. The waste liquid generated after the reaction in the deodorizing chamber 3-3 flows back into the housing 1-3 through the return pipe 3-7 to participate in the treatment again.

[0030] The water inlet 4 is arranged at the upper part of the side wall of the housing 1-3, and the drain outlet 5 is arranged at a corner of the bottom of the housing 1-3 for discharging the treated water body. A pulley 6 is arranged under the bottom plate of the housing 1-3, which is convenient for moving the device.

[0031] The operation process of the present utility model is as follows:

[0032] First, put sewage into the water inlet 4. Start the first pump 2-2, and the deodorant can be sprayed into the housing 1-3 through the spray head 2-3. Start the stirring device 1-1, and the stirring blade 1-1-3 rotates to stir. At the same time, start the air pump 1-2-1, and the aeration head 1-2-2 aerates at the bottom to add gas to the water body. The rotating stirring blade 1-1-3 can make the medicine, water body and gas mix more fully, react more fully, and improve the deodorization effect.

[0033] The odor in the housing 1-3 enters the deodorization chamber 3-3 through the air inlet pipe 3-2. At the same time, start the second pump 2-4, and the atomized deodorant can be sprayed into the deodorization chamber 3-3 through the atomizing nozzle 2-5. The odor reacts with the atomized deodorant sprayed by the atomizing nozzle 2-5 and the deodorant adsorbed on the adsorption plate 3-4 for deodorization. Then, it is further adsorbed and deodorized by passing through the activated carbon plate 3-5, and finally discharged through the exhaust pipe 3-6. The waste liquid generated after the reaction in the deodorization chamber 3-3 flows back to the housing 1-3 through the return pipe 3-7 to participate in the treatment process again.

[0034] Finally, the treated water body is discharged from the drain outlet 5.
