[0002] Currently, livestock farming enterprises are undergoing intensive and large-scale development, with the size of individual units increasing. The safe emission of air has gradually become a pain point for these enterprises. In traditional farms, the odor generated in livestock and poultry houses is usually discharged directly into the environment, causing environmental pollution. In the existing technology, in order to eliminate the odor discharged from livestock and poultry houses, the odor is usually introduced into a pool so that the odor dissolves in the water of the pool. However, after such long-term treatment of the odor, the water in the pool will become contaminated, and the water in the pool needs to be frequently replaced. The operation process is complicated and the deodorization cost is high. Summary of the Invention

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0033] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0035] Please refer to Figure 1This embodiment provides a breeding system 1, which includes a livestock and poultry house 11 and a farm deodorization device 12. The farm deodorization device 12 includes a box 121, which is arranged side by side with the livestock and poultry house 11. The box 121 is provided with an air inlet 1211, a deodorization area 1212 and an air outlet 1213. The air inlet 1211 is connected to the livestock and poultry house 11. The odor generated in the livestock and poultry house 11 can enter the box 121 through the air inlet 1211. After the odor diffuses to the deodorization area 1212, it will be eliminated. The gas output from the air outlet 1213 no longer has an odor, and the gas output from the air outlet 1213 will not cause pollution to the environment.

[0036] For details, please refer to Figure 1 In this embodiment, the farm deodorization device 12 also includes a ventilation fan 122, which is arranged at the air inlet 1211. After the ventilation fan 122 is started, the gas in the livestock house 11 can be transported to the box 121, thereby improving the overall deodorization efficiency.

[0037] Please refer to Figure 1 and Figure 2 In this embodiment, the farm deodorization device 12 also includes a spraying part 123, a water pool 124 and an action part 125. The spraying part 123, the water pool 124 and the action part 125 are all arranged in the deodorization area 1212. Under the joint action of the spraying part 123, the water pool 124 and the action part 125, the odor entering the box body 121 can be deodorized.

[0038] Specifically, in this embodiment, the spraying member 123 is provided with a liquid outlet and a liquid inlet. The liquid outlet is used to spray the first water body to the action member 125. After the first water body is sprayed out, the odor flowing from the air inlet 1211 to the deodorization area 1212 can be dissolved in the first water body to form a mixed liquid. The mixed liquid will flow to the action member 125. The action member 125 can nitrify and denitrify the mixed liquid, so that the nitrogen element in the mixed liquid forms nitrogen gas. After the mixed liquid releases the nitrogen gas, it forms a second water body.

[0039] It is understandable that, in this embodiment, after the nitrogen element in the mixed liquid forms nitrogen gas, the active member 125 performs an effective deodorization operation, and the nitrogen gas released into the environment will not cause pollution to the environment.

[0040] Furthermore, in this embodiment, the water pool 124 can receive the aforementioned second water body. This second water body entering the water pool 124 does not contaminate the water within the water pool 124 and can be re-transferred to the liquid inlet of the spray element 123. The spray element 123 then uses the second water body for spraying, thereby achieving water recycling, reducing water loss, and saving costs. Furthermore, the water within the water pool 124 does not need to be frequently replaced, simplifying subsequent maintenance procedures and reducing maintenance costs.

[0041] It should be noted that in this embodiment, after the second water body enters the spray element 123, it can be sprayed out from the liquid outlet of the spray element 123, and the second water body is converted into the first water body. It should be noted that in this embodiment, for the convenience of description, the water bodies at different stages are named as the first water body and the second water body. The first water body and the second water body represent different stages of the water body in the deodorization process, and the content of the first water body and the second water body are not specifically distinguished.

[0042] It should be noted that, in this embodiment, the aforementioned nitrification refers to the process in which ammonia removed from amino acids is converted into nitric acid by the action of nitrite bacteria and nitrate bacteria under aerobic conditions. The aforementioned denitrification refers to the process in which bacteria convert nitrate (NO3 - ) through a series of intermediate products (NO2 - , NO, N2O) to nitrogen (N2) biochemical process.

[0043] Please refer to Figure 2 In this embodiment, the active member 125 includes a biological filter bed 1251 , which is disposed between the spray member 123 and the water pool 124 , and a biological layer 1252 is laid on the biological filter bed 1251 .

[0044] In actual use, biofilter bed 1251 receives the mixed liquid, which then falls onto biological layer 1252. This biological layer 1252 provides a carbon source for the aforementioned nitrification and denitrification processes, ensuring their proper function. After the mixed liquid releases nitrogen, it forms a secondary water body, which then falls from biofilter bed 1251 into pool 124 and then into spray element 123 for recycling.

[0045] In this embodiment, the spray element 123 and the water pool 124 can be connected through a pipe 126. Optionally, a water pump is provided on the pipe 126, which can increase the movement speed of the second water body, so that the second water body reaches the spray element 123 faster, thereby improving the circulation efficiency of the second water body.

[0046] Specifically, in this embodiment, the biological layer 1252 includes a plurality of husk particles, which are laid on the biological filter bed 1251. In this embodiment, the plurality of husk particles can not only provide a carbon source for nitrification and denitrification, but also have good adsorption properties.

[0047] That is to say, after the mixed liquid falls onto the biological filter bed 1251, the husk particles can adsorb the mixed liquid, prolonging the time the mixed liquid stays in the biological filter bed 1251, so that the mixed liquid has enough time to undergo nitrification and denitrification, thereby reducing the toxic elements in the mixed liquid as much as possible.

[0048] Please refer to Figure 2 and Figure 3 In this embodiment, the action member 125 further includes a guide body 1253 , which is disposed between the spray member 123 and the biological filter bed 1251 .

[0049] In this embodiment, the first water body sprayed by the spray element 123 will first flow through the guide body 1253, and the guide body 1253 can guide the first water body to flow toward the biological filter bed 1251, which can reduce the splashing of the first water body.

[0050] It should be noted that in this embodiment, heterotrophic nitrifying and aerobic denitrifying bacteria are attached to the surface of guide body 1253. It is understood that after the first water body flows through guide body 1253, the heterotrophic nitrifying and aerobic denitrifying bacteria can dissolve in the first water body and then follow the first water body to fall onto biofilter bed 1251. There, the heterotrophic nitrifying and aerobic denitrifying bacteria then combine with biological layer 1252 on biofilter bed 1251 to nitrify and denitrify the mixed liquid, thereby performing a deodorization operation.

[0051] It is worth noting that in this embodiment, heterotrophic nitrification and aerobic denitrification bacteria can perform both nitrification and denitrification.

[0052] Alternatively, in other embodiments, a portion of the bacteria may be used to perform nitrification alone, and another portion of the bacteria may be used to perform denitrification alone.

[0053] It should be noted that in this embodiment, when the first water body flows through the guide body 1253, the odor entering from the air inlet 1211 will also dissolve in the first water body to form a mixed liquid, which will fall onto the biological filter bed 1251 after leaving the guide body 1253.

[0054] It should be noted that in this embodiment, the guide body 1253 is a flexible fabric structure. Thus, the fabric guide body 1253 can absorb the first water body. After the odor comes into contact with the guide body 1253, it can also dissolve into the first water body, thereby forming a mixed liquid, which then flows onto the biofilter bed 1251.

[0055] It can be understood that the guide body 1253 can increase the contact area between the first water body and the odor, so that the odor can be more easily dissolved in the first water body.

[0056] It should be noted that in this embodiment, guide body 1253 is made of a microbially friendly material and serves as a carrier for the microorganisms. In this embodiment, guide body 1253 facilitates the colonization of heterotrophic nitrifying and aerobic denitrifying bacteria, which form a biofilm on guide body 1253. After the first water body flows through guide body 1253, the heterotrophic nitrifying and aerobic denitrifying bacteria can dissolve in the first water body.

[0057] Optionally, a fixing frame is installed on the outer periphery of the guide body 1253 to form a screen structure. In this way, the fixing frame can reinforce the guide body 1253 and improve the stability of the guide body 1253.

[0058] Please refer to Figure 2 and Figure 3 In this embodiment, the number of guide bodies 1253 is at least two, and at least two guide bodies 1253 can guide the first water body. The first water bodies on different guide bodies 1253 can be dissolved in odor, which can absorb more odor, so that a large amount of odor can be deodorized at the same time, thereby improving the deodorization efficiency.

[0059] It is understood that in this embodiment, a gas passage 1254 may be formed between two adjacent guide bodies 1253. In this way, other gases not dissolved in the first water body can flow into the external environment through the gas passage 1254. In addition, nitrogen generated after nitrification and denitrification can also flow into the external environment through the gas passage 1254.

[0060] Please refer to Figure 3 In this embodiment, at least a portion of the guide body 1253 is bent, with the bent portions of two adjacent guide bodies 1253 corresponding to each other. This allows the gas passage 1254 to extend in a zigzag pattern, increasing the time it takes for gas to pass through the passage 1254. This allows odors in the gas to dissolve in the first water body over a longer period of time, minimizing the risk of odors from escaping through the passage 1254 into the external environment.

[0061] Optionally, the guide body 1253 may be bent in one part or in multiple parts.

[0062] Please refer to Figure 4This embodiment also provides a method for deodorizing a farm, which is implemented using the aforementioned farm deodorizing device 12. Specifically, the method includes:

[0063] S31 : The liquid outlet of the spraying member 123 is caused to spray the first water body toward the action member 125 .

[0064] S32: The action element 125 performs nitrification and denitrification on the mixed liquid, so that the mixed liquid forms a second water body.

[0065] S33 : The water pool 124 receives the second water body and delivers the second water body to the liquid inlet portion of the spraying member 123 .

[0066] It should be noted that in this embodiment, after step S33 is completed, step S31 can be repeated, and the second water body can be recycled and used as the first water body in the next cycle to perform the deodorization operation again. Therefore, in this embodiment, the water in the water pool 124 using the above-mentioned farm deodorization method can be reused, eliminating the need for frequent water replacement, reducing water consumption, and lowering subsequent maintenance costs.

[0067] In summary, the working principle of the farm deodorization device 12 provided in this embodiment is as follows:

[0068] The liquid outlet of spray element 123 sprays the first water body. The first water body passes through guide body 1253, where odor and heterotrophic nitrification and aerobic denitrification bacteria dissolve in the first water body, forming a mixed liquid. The mixed liquid falls onto biofilter bed 1251. There, heterotrophic nitrification and aerobic denitrification bacteria combine with husk particles to undergo nitrification and denitrification. After the mixed liquid releases nitrogen, it forms a second water body, which flows into pool 124. This second water body does not pollute the water in pool 124. Furthermore, the second water body can flow from pool 124 into spray element 123 to resume the next deodorization step.

[0069] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
