[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 2As shown, an embodiment of the present invention provides a method for fermenting and deodorizing organic materials, comprising: piling organic materials into piles in a fermentation workshop 10; performing aerobic aeration fermentation on the organic materials through an aeration device; sucking the odor generated after the aerobic aeration fermentation of the organic materials into a deodorization workshop 20; performing a primary deodorization on the odor through a deodorization pool in the deodorization workshop 20; a spraying device comprising a wet curtain net and a plurality of spray pipes, the spray pipes being arranged above the wet curtain net, the deodorization pool being located below the wet curtain net, the spray pipes being used to transport wood vinegar liquid to the wet curtain net, the deodorization pool receiving water flowing down from the wet curtain net; the wood vinegar liquid on the wet curtain net being discharged from the deodorization pool The overflowed odor is absorbed for a second time, and the water that has absorbed the odor flows into the deodorizing water tank; the sewage treatment system 30 includes a sedimentation tank 31, a purification tank 32 and a storage tank 33 that are connected in sequence. The sedimentation tank 31 is connected to the water outlet of the deodorizing water tank, and the water outlet of the storage tank 33 is connected to the spray pipe. The sedimentation tank 31 is used to precipitate impurities entering from the deodorizing water tank, the purification tank 32 is used to purify the water entering from the sedimentation tank 31, and the storage tank 33 is used to store the water entering from the purification tank 32; the water in the deodorizing water tank passes through the sedimentation tank 31, the purification tank 32 and the storage tank 33 in sequence, and the water in the storage tank 33 is transported to the spray pipe.

[0030] This solution allows for the initial deodorization of odors generated by aerobic fermentation of organic materials in a deodorizing tank. The odors that overflow from the deodorizing tank are then subjected to secondary deodorization by a spraying device. This arrangement effectively absorbs the odors, further achieving the goal of complete odor absorption and effectively resolving the problem of poor deodorization effectiveness in the prior art. Furthermore, in this solution, the water in the deodorizing tank can be sequentially passed through a sedimentation tank 31, a purification tank 32, and a storage tank 33 for sedimentation, purification, and storage. The treated water is then transported to the spraying device, allowing for water recycling and improving resource utilization. The odor is a mixture of ammonia, carbon dioxide, and sulfur dioxide. To prevent clogging of the spray pipe, the water in the deodorizing tank is replaced every four days.

[0031] The initial deodorization of odors by the deodorization pool includes: transporting the odors to the bottom of the deodorization pool, and absorbing the odors by the water in the deodorization pool. With the above arrangement, since ammonia, carbon dioxide, and sulfur dioxide are all soluble in water, the odors can be absorbed by the water in the deodorization pool.

[0032] Specifically, the concentration of the wood vinegar is 50% to 60%. Setting the concentration of the wood vinegar to 50% to 60% can improve the absorption effect of the odor and ensure that the odor is completely absorbed.

[0033] In this embodiment, the process of drawing the odor generated by aerobic aeration fermentation of the organic material into the deodorization workshop 20 includes: using an exhaust fan to draw the odor generated by aerobic aeration fermentation of the organic material into an odor conveying pipe, and then transporting the odor into the deodorization workshop 20 through the odor conveying pipe. With this arrangement, the exhaust fan can draw the odor into the odor conveying pipe, thereby transporting the odor from the fermentation workshop 10 to the deodorization workshop 20.

[0034] Specifically, aerobic aeration and fermentation of organic materials using an aeration device includes: using an aeration fan in the aeration device to draw outside air into an aeration duct in the aeration device, and transporting the outside air through the aeration duct to the organic material storage area to enable aerobic aeration and fermentation of the organic materials; dividing the fermentation workshop 10 into multiple zones along its length, and determining whether to turn on the aeration fans in the corresponding zones based on the temperature in the zones. In this embodiment, the aeration fans can draw outside air into the aeration ducts, the aeration ducts are laid side by side on the floor of the fermentation workshop 10, and the aeration ducts are provided with multiple exhaust holes at intervals. Organic materials are stored on the aeration ducts, thereby achieving aerobic aeration and fermentation of the organic materials; and determining whether to turn on the aeration fans in the corresponding zones based on the temperature in the zones, thereby optimizing the aerobic aeration and fermentation of the organic materials.

[0035] The method comprises: dividing the fermentation workshop 10 into a first area, a second area, a third area, and a fourth area along a length direction of the fermentation workshop 10, wherein the length of the first area is 0-20 m, the length of the second area is 20-40 m, the length of the third area is 40-60 m, and the length of the fourth area is 60-80 m;

[0036] When the temperature of the first zone is higher than 68°C, the aeration fan is turned on, and when the temperature of the first zone is lower than 65°C, the aeration fan is turned off;

[0037] When the temperature of the second area is higher than 65°C, the aeration fan is turned on, and when the temperature of the second area is lower than 60°C, the aeration fan is turned off;

[0038] When the temperature of the third zone is higher than 60°C, the aeration fan is turned on; when the temperature of the third zone is lower than 55°C, the aeration fan is turned off;

[0039] When the temperature of the fourth area is higher than 45°C, the aeration fan is turned on, and when the temperature of the fourth area is lower than 40°C, the aeration fan is turned off.

[0040] The fermentation workshop 10 is divided into a first area, a second area, a third area, and a fourth area. In this way, the aeration fan in each area can be judged according to the temperature of each area, thereby optimizing the aerobic aeration fermentation effect of the organic material. In addition, turning on the aeration fan can also play a role in heat dissipation.

[0041] Alternatively, the organic material fermentation and deodorization method further includes turning the organic material using a turning machine; and determining whether to activate the turning machine in a corresponding area based on the temperature and ammonia concentration in the area. In this embodiment, the organic material can also be turned using the turning machine. This further enhances the aerobic aeration fermentation effect of the organic material.

[0042] Among them, judging whether to start the turning machine in the corresponding area according to the temperature and ammonia concentration in different areas includes:

[0043] The fermentation workshop 10 is divided into a first area, a second area, a third area and a fourth area in sequence along the length direction of the fermentation workshop 10. The length of the first area is 0-20m, the length of the second area is 20-40m, the length of the third area is 40-60m, and the length of the fourth area is 60-80m.

[0044] When the temperature of the first area is higher than 68°C and the ammonia concentration is greater than or equal to 80%, the turner is turned on; when the temperature of the first area is lower than 65°C and the ammonia concentration is lower than 80%, the turner is turned off;

[0045] When the temperature of the second area is higher than 65°C and the ammonia concentration is greater than or equal to 80%, the turner is turned on; when the temperature of the second area is lower than 60°C and the ammonia concentration is less than 80%, the turner is turned off;

[0046] When the temperature of the third area is higher than 60°C and the ammonia concentration is greater than or equal to 80%, the turner is turned on; when the temperature of the third area is lower than 55°C and the ammonia concentration is less than 80%, the turner is turned off;

[0047] When the temperature of the fourth area is higher than 45°C and the ammonia concentration is greater than or equal to 80%, the turner is turned on; when the temperature of the fourth area is lower than 40°C and the ammonia concentration is lower than 80%, the turner is turned off.

[0048] Since the first area is the feed port of the fermentation workshop 10, the fermentation temperature is high. When the temperature of the first area is higher than 68°C and the ammonia concentration is greater than or equal to 80%, the turning machine starts turning and turning the organic material in the first area to the second area. When the temperature of the second area is higher than 65°C and the ammonia concentration is greater than or equal to 80%, the turning machine starts turning and turning the organic material in the second area to the third area. When the temperature of the third area is higher than 60°C and the ammonia concentration is greater than or equal to 80%, the turning machine starts turning and turning the organic material in the third area to the fourth area. When the temperature of the fourth area is higher than 45°C and the ammonia concentration is greater than or equal to 80%, the turning machine turns and turns the organic material, and the material is screened and sent to the aging workshop for aging.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
