Then, through the cooperative design of the spraying assembly 4, the odor can be sprayed, so that the particles or impurities in the odor are wetted, and thus the particles or impurities in the odor sink, thereby filtering the odor. Refer to Figures 1-3, which mainly includes a pretreatment box 1 and an air inlet pipe 2. The air inlet pipe 2 is installed on one side of the pretreatment box 1. It is characterized in that: a first filter screen 3 is installed at the upper middle part inside the pretreatment box 1, and a spraying component 4 for spraying the odor is provided at the upper end inside the pretreatment box 1. The pretreatment box 1 is communicated with a deodorization box 7 through a connecting pipe 6. Inside the deodorization box 7, a first deodorization component 8 and a second deodorization component 9 are installed in sequence from bottom to top; through the combined design of the first deodorization component 8 and the second deodorization component 9, the odor can be deodorized multiple times, making the deodorization effect better.

[0024] For re-deodorizing the odor. In this embodiment, referring to Figure 1 , Figure 2 and Figure 3 , the spraying component 4 includes a water storage tank 401, a water suction pipe 402, a water suction pump 403, a spraying pipe 404, a connecting pipe 405 and a spraying head 406. The water storage tank 401 is located on one side of the upper end of the pretreatment box 1. A water suction pipe 402 is communicated with the lower end on one side of the water storage tank 401. A water suction pump 403 is installed on the water suction pipe 402. The end of the water suction pipe 402 away from the water storage tank 401 penetrates through the pretreatment box 1 and is communicated with a plurality of spraying pipes 404 arranged side by side. And adjacent two spraying pipes 404 are communicated through a connecting pipe 405. A plurality of spraying heads 406 for spraying the odor are installed at the lower end of each spraying pipe 404. During specific use, start the water suction pump 403. The water in the water storage tank 401 can be pumped into the spraying pipe 404 and the connecting pipe 405 through the water suction pipe 402, and finally sprayed out by the spraying heads 406 to spray the odor, thereby wetting the particles or impurities in the odor, making the particles or impurities sink, and thus re-filtering the odor, making the filtering effect better.

[0025] To avoid waste of water resources. In this embodiment, referring to Figure 2 , the lower end inside the pretreatment box 1 is communicated with the water storage tank 401 through a circulation pipe 11. A circulation pump 12 is installed on the circulation pipe 11. During specific use, start the circulation pump 12, and pump the water at the lower end inside the pretreatment box 1 into the water storage tank 401 through the circulation pipe 11, thereby the sprayed water can be reused again, effectively avoiding waste of water resources.

[0026] To avoid the sprayed water from blocking the circulation pipe 11. In this embodiment, referring to Figure 1 , a second filter screen 5 is installed at the lower middle part inside the pretreatment box 1. Through the setting of the second filter screen 5, the sprayed water can be filtered, effectively avoiding the sprayed water from blocking the circulation pipe 11.

[0027] To avoid the first filter screen 3 and the second filter screen 5 from affecting the filtering effect due to blockage. In this embodiment, referring to Figure 1The first filter screen 3 and the second filter screen 5 are both arranged tilted, so that the particles or impurities on the first filter screen 3 and the second filter screen 5 can flow to the lower end, effectively avoiding the influence of the filtering effect due to blockage.

[0028] In order to deodorize the odor. Figure 1 The first deodorizing component 8 includes a breathable plate 801 and a microbial layer 802. The microbial layer 802 is arranged on the upper end of the breathable plate 801. The microbial layer 802 is a complex ecosystem composed of a large number of microbial communities and their living environment. The microorganisms in the microbial layer 802 decompose and transform the adsorbed and absorbed odor substances through their physiological metabolic activities. These microorganisms use the odor substances as energy and nutrients, and transform them into harmless or low-harm simple inorganic substances such as carbon dioxide, water, sulfate, nitrate, etc. through a series of biochemical reactions. This process not only effectively removes odor, but also realizes the recycling of resources.

[0029] In order to deodorize the odor again. Figure 1 The second deodorizing component 9 includes a placement plate 901, a baffle 902 and bamboo charcoal 903. A plurality of placement plates 901 are installed at staggered and inclined intervals inside the deodorizing box 7. A plurality of bamboo charcoals 903 are evenly spaced on each placement plate 901, and a plurality of baffles 902 are fixedly connected to each placement plate 901 to prevent the bamboo charcoal 903 from falling. The bamboo charcoal 903 has a loose and porous structure, fine and porous molecules, and a hard texture. This structure gives the bamboo charcoal 903 a strong adsorption capacity, which can adsorb odor, and the placement plates 901 are arranged at staggered and inclined intervals, which can prolong the residence time of the odor in the deodorizing box 7, thereby making the deodorizing effect better; in addition, the bamboo charcoal 903 also has good humidity regulating performance, which can absorb moisture when the ambient humidity is high and release moisture when the ambient humidity is dry, thereby ensuring the humidity balance in the deodorizing box 7 and providing a good environment for the survival of microorganisms.

[0030] In order to facilitate the exhaust of the gas in the deodorizing box 7. Figure 1 , Figure 2 and Figure 3 An air outlet pipe 10 is installed at the upper end of one side of the deodorizing box 7, and the gas in the deodorizing box 7 can be discharged through the air outlet pipe 10.

[0031] Working principle of the deodorization device for biological filter tank of the present utility model: When the device is in use, the odor is introduced into the pretreatment tank 1 through the intake pipe 2. After being filtered by the first filter screen 3, it flows to the upper end inside the pretreatment tank 1. Then, the water pump 403 is started, and water is pumped into the spraying pipe 404 through the water suction pipe 402 and the connecting pipe 405, and finally sprayed out by the spray head 406 to spray the odor, which can wet the odor, so that the particles or impurities contained in the odor settle down, thus the odor can be filtered again, making the filtering effect better. The filtered odor flows into the deodorization tank 7 through the connecting pipe 6. After being purified by the reaction of the microbial layer 802, it flows to the upper end inside the deodorization tank 7, and then the odor can be further purified through the adsorption of the bamboo charcoal 903, making the deodorization effect better. Finally, the gas in the deodorization tank 7 is discharged through the outlet pipe 10.
