[0031] As Figure 3 and Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the circulation recovery component 11 includes a recovery pipe 111 installed between the water outlet of the first recovery hopper 9 and the water inlet of the liquid storage tank 401 and between the water outlet of the second recovery hopper 10 and the water inlet of the maintenance tank 701.

[0032] As Figure 2 and Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, filter meshes 12 are provided at the tops of the first recovery hopper 9 and the second recovery hopper 10. An air inlet communicating with the first chamber is provided on the deodorizing box 1, and an induced draft fan 13 is provided at the air inlet. The induced draft fan 13 is installed on the outer wall of the liquid storage tank 401 through a bracket. An air outlet 14 communicating with the second chamber is further provided on the deodorizing box 1, realizing two-stage treatment of the gas, and finally the purified gas is discharged from the air outlet 14.

[0033] As Figure 1 , Figure 2 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, an electric control box 15 is installed on the outer side wall of the deodorizing box 1. The electric control box 15 is electrically connected to the output end of the driving incomplete gear 602, the liquid pump 402, the suction pump 702 and the diversion pump 112, realizing the automatic operation of the equipment and improving the working efficiency and operation stability.

[0034] Specifically, when this biological deodorizing equipment is in use: First, the waste gas containing malodorous gas enters the first chamber of the deodorizing box 1 through the air inlet provided on the deodorizing box 1 under the action of the induced draft fan 13; the induced draft fan 13 is installed on the outer wall of the liquid storage tank 401 through a bracket, which can provide stable air intake power, ensure the smooth entry of the waste gas into the treatment system, and prepare for the subsequent deodorizing treatment; The deodorizing spray mechanism 4 starts to work; the liquid pump 402 is started to extract the deodorizing liquid from the liquid storage tank 401. The deodorizing liquid is successively transported to the spray pipe 405 through the liquid inlet pipe 403, the liquid pump 402 and the liquid delivery pipe 404; the deodorizing liquid is evenly sprayed on the spray packing particles in the first chamber through the nozzles 406 installed on the spray pipe 405; the waste gas is in full contact with the spray packing particles, and the chemical components in the deodorizing liquid react with the malodorous substances in the waste gas, or part of the malodorous substances are removed through physical adsorption, thereby realizing the preliminary purification of the waste gas; The gas treated in the first chamber enters the second chamber through the openings on the partition plate 2; when the gas enters the second chamber, the V-shaped gas retention plate 801 plays a role in hindering and buffering the gas, reducing the gas flow rate and evenly dispersing it to both sides at the same time. The flow guide plate 802 further guides the gas flow direction to ensure that the gas can flow evenly to each hollow adsorption cylinder 5, creating conditions for full contact with the microbial packing in the follow-up; The hollow adsorption cylinder 5 is filled with microbial packing. After the malodorous substances in the gas enter the hollow adsorption cylinder 5, they are adsorbed by the microbial packing. The microorganisms in the microbial packing take the malodorous substances as nutrient sources, degrade and transform them, and decompose the malodorous substances into harmless substances; Meanwhile, start the driving incomplete gear 602. When the teeth on the driving incomplete gear 602 mesh with the driven gear 603, the driven gear 603 rotates accordingly; thereby intermittently driving one set of transmission shafts 51 to rotate. The rotation of the transmission shafts 51 causes the corresponding hollow adsorption cylinders 5 to rotate intermittently, so that different parts of the microbial packing can fully contact with the gas, avoiding the failure of local microbial packing due to overuse, and improving the utilization rate and treatment effect of the microbial packing; Meanwhile, the belt pulley 303 installed at the top of one set of transmission shafts 51 drives the driven belt pulley 302 to rotate intermittently through the transmission belt 304. The driven belt pulley 302 drives the stirring rod 301 and the stirring blades 305 to rotate intermittently, thereby stirring the liquid and packing in the first chamber, making the gas mix and contact more fully with the deodorizing liquid and the sprayed packing particles, increasing the reaction time and contact area, and further improving the deodorization efficiency; When it is necessary to maintain the microbial packing, start the suction pump 702 to extract the maintenance liquid from the maintenance box 701; the maintenance liquid passes through the suction pipe 703, the suction pump 702, and the supply pipe 704 in sequence and is transported to the dispersion pipe 705. The maintenance liquid is evenly sprayed on the microbial packing in the hollow adsorption cylinder 5 through the spray heads 706 installed on the outer wall of the dispersion pipe 705, providing a suitable growth environment for the microorganisms, such as suitable moisture, nutrients, etc., promoting the growth and reproduction of the microorganisms, and enhancing the degradation ability of the microorganisms to the malodorous substances; The liquids in the first chamber and the second chamber are respectively collected by the first recovery hopper 9 and the second recovery hopper 10. Filter meshes 12 are arranged at the tops of the first recovery hopper 9 and the second recovery hopper 10. The filter meshes 12 can filter out the impurities in the liquid, preventing the impurities from entering the recovery system and causing blockage; start the diversion pump 112 in the circulation recovery assembly 11, and transport the recovered liquid back to the liquid storage tank 401 and the maintenance box 701 through the recovery pipe 111; one-way valves are arranged at the joints of the recovery pipe 111 with the liquid storage tank 401 and the maintenance box 701. The one-way valves can prevent the liquid from flowing back, ensuring that the liquid can stably flow back to the corresponding storage containers, realizing the recycling of the liquid and saving resources; Finally, the gas after two-stage treatment is discharged through the air outlet 14 provided on the deodorization box 1. At this time, the content of the malodorous substances in the discharged gas is greatly reduced, achieving the purpose of deodorization and reducing the harm to the environment and human health.

[0035] All the technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
