Description

Technical Field

[0001] This invention belongs to the field of deodorization equipment technology, specifically relating to an odor treatment device and odor treatment method. Background Technology

[0002] Odor treatment refers to the treatment of various odorous gases. Currently, in the process of sludge treatment and disposal, especially in the transportation and storage of wet sludge, the concentration of odorous gases emitted by the sludge is high and the composition is complex. Therefore, it is usually necessary to use biological deodorization towers to treat the odor.

[0003] Biological deodorization towers in related technologies typically consist of a tower body and a packing layer. Odorous gases are introduced into the tower body, and then microorganisms on the packing layer decompose the malodorous gases, thus achieving a deodorizing effect. However, during the process of treating odorous gases, the number of microorganisms continuously decreases, affecting the deodorization effect. Furthermore, in these deodorization towers, replenishing the packing layer with microorganisms often requires shutdown, which further reduces deodorization efficiency.

[0004] It is evident that the treatment devices in the relevant technologies suffer from drawbacks such as poor deodorization effect, difficulty in replenishing microorganisms in the packing layer, and poor deodorization efficiency. Therefore, improving the odor treatment effect, facilitating the replenishment of microorganisms in the packing layer, and improving deodorization efficiency are of great significance. Summary of the Invention

[0005] In order to solve all or some of the above problems, the purpose of this invention is to provide an odor treatment device and odor treatment method, which can improve the odor treatment effect and deodorization efficiency, and also facilitate the replenishment of microorganisms to the packing layer by the staff.

[0006] In a first aspect, the present invention provides an odor treatment apparatus, comprising:

[0007] The first tower body is used for the initial treatment of odor. The top of the first tower body is connected to an air inlet pipe, the inside is equipped with a first packing material, and the bottom is equipped with a first water tank. The first tower body is equipped with a first spraying device, which is used to extract the solution in the first water tank and spray the solution onto the first packing material.

[0008] The second tower body is used to further treat the odor. The top of the second tower body is connected to an exhaust pipe, the inside is equipped with a second packing material, and the bottom is equipped with a second water tank. The second tower body is equipped with a second spraying device, which is used to extract the solution in the second water tank and spray the solution onto the second packing material.

[0009] The air intake channel is connected at one end to the first tower body and at the other end to the second tower body;

[0010] Microbial culture components, used for culturing bacterial solutions;

[0011] A support plate is horizontally set in the air intake channel. Support frames are hinged to both sides of the support plate. The two ends of the support plate and the two support frames are sealed together with elastic material to form a trapezoidal storage space between the support plate and the two support frames. The storage space is filled with coconut fiber filler to serve as a microbial culture carrier.

[0012] The drip irrigation component has one end connected to the microbial culture component and the other end located in the storage space. The microbial culture component can deliver the cultured bacterial solution to the coconut fiber filler through the drip irrigation component.

[0013] The air intake channel is equipped with a driving component, which controls the two support frames to move closer to each other and compress the coconut fiber filler, thereby squeezing out the bacterial liquid inside the coconut fiber filler. When the odorous gas flows through the air intake channel, the squeezed-out bacterial liquid can be blown into the second water tank by the odorous gas. When the second spraying component performs a spraying operation, it can spray the bacterial liquid onto the second filler to replenish the microorganisms inside the second filler.

[0014] Optionally, each of the support frames is inclinedly fixed with multiple air guide plates, which are parallel to each other and evenly arranged in the vertical direction. The support plate is vertically slidably connected to the air intake channel. When the driving component controls the two support frames to move closer or further apart, the support plate can slide vertically under the action of the two support frames. At this time, the angle between the air guide plate and the horizontal plane changes, and the distance between the support plate and the bottom wall of the air intake channel changes, so as to change the cross-sectional area of ​​the air intake channel, thereby realizing the adjustment of the air intake volume.

[0015] Optionally, the driving element includes:

[0016] Two reversible motors are provided, each horizontally slidably connected to the air intake channel.

[0017] Two gears are fixedly mounted on the output shafts of the corresponding forward and reverse motors.

[0018] A rack is horizontally fixed on the air intake channel, and the two gears respectively mesh with the rack;

[0019] There are two drive rods, each fixed to a corresponding forward and reverse motor, and each drive rod is rotatably connected to a corresponding support frame.

[0020] Optionally, the microbial culture component includes:

[0021] An incubator serves a storage function, and the drip irrigation assembly is connected to the incubator;

[0022] A storage tank for storing microbial powder, the storage tank being connected to the incubator via a feeding pipe, and the feeding pipe being equipped with a powder pump;

[0023] A gas-liquid mixing pump is connected to the incubator, and the gas-liquid mixing pump is used to simultaneously blow liquid and air into the incubator;

[0024] A stirrer is installed inside the incubator and is used to mix and stir the bacterial powder and liquid.

[0025] When the gas-liquid mixing pump operates and increases the pressure inside the incubator, the bacterial solution inside the incubator can enter the coconut fiber filler through the drip irrigation assembly.

[0026] Optionally, the microbial culture assembly further includes:

[0027] A wet sludge pipe is connected to the first water tank and is used to add wet sludge into the first water tank;

[0028] A composite humic acid pipe is connected to the first water tank and is used to add humic acid compound fertilizer to the first water tank to cultivate microorganisms in the wet sludge.

[0029] The suction tube is connected at one end to the first water tank and at the other end to the inlet of the gas-liquid mixing pump.

[0030] The solution in the first water tank is divided into a supernatant layer, a colloidal layer and a sediment layer from top to bottom. The microorganisms cultured in the sludge are located in the colloidal layer, and the end of the suction tube is located in the colloidal layer so that the colloidal layer can be extracted into the incubator.

[0031] Optionally, a partition plate is vertically fixed inside the incubator, dividing the incubator into a dosing chamber and a culture chamber. The stirrer is located in the culture chamber. The suction pipe, feeding pipe, and gas-liquid mixing pump are respectively connected to the culture chamber. The drip irrigation assembly is connected to the dosing chamber. An overflow port is provided at the upper end of the partition plate, and the overflow port connects the dosing chamber and the culture chamber.

[0032] Optionally, the drip irrigation assembly includes:

[0033] A drip irrigation pipe is installed between the two support frames;

[0034] Multiple drip irrigation nozzles are provided, each connected to the drip irrigation pipe.

[0035] The drain pipe is connected at one end to the drip irrigation pipe and at the other end to the dosing chamber.

[0036] Optionally, the drip irrigation nozzle is arranged at an angle, and the drain end of the drip irrigation nozzle faces the second water tank.

[0037] Optionally, the second water tank is connected to a yucca extract pipe, which is used to add yucca extract powder into the second water tank to improve the activity of microorganisms in the second water tank.

[0038] In a first aspect, the present invention provides an odor treatment method using the above-mentioned odor treatment device, comprising the following steps:

[0039] S1, introduce the odor into the air inlet pipe, and at the same time add wet sludge and humic acid compound fertilizer to the first water tank to cultivate microorganisms in the wet sludge, thereby achieving the first targeted cultivation of microorganisms. Meanwhile, add yucca extract powder to the second water tank.

[0040] S2, the solution containing microorganisms in the first water tank is drawn into the microbial culture component, and microbial powder is added into the microbial culture component. The solution and microbial powder are mixed and stirred to achieve the second directional culture of microorganisms.

[0041] S3, the bacterial solution in the microbial culture component is transported to the coconut fiber filler through the drip irrigation component, so that the microorganisms can undergo a third directional culture in the coconut fiber filler;

[0042] S4, squeeze the coconut coir filler to squeeze out the bacterial liquid inside the coconut coir filler. At this time, the odorous air flows through the air inlet channel and blows the squeezed bacterial liquid into the second water tank. At the same time, when the second spraying component sprays the second filler layer, the bacterial liquid and the nutrient solution containing yucca extract powder are sprayed together on the second filler to replenish the microorganisms in the second filler.

[0043] S5, change the water in the first water tank and the second water tank. The water tank is changed every 6 hours, and 1 / 3 of the water is changed each time. The water tank is changed every 12 hours, and 1 / 3 of the water is changed each time.

[0044] Meanwhile, the amount of wet sludge and humic acid compound fertilizer in the first water tank is 100g and 100ml respectively, and the addition frequency is 1h / time. The amount of yucca extract in the second water tank is 100g / m3 of drainage volume, and the addition frequency is 1 day / time.

[0045] As can be seen from the above technical solutions, the odor treatment device and odor treatment method provided by the present invention have the following advantages:

[0046] This design allows for the replenishment of microorganisms within the second packing material, ensuring a sufficient number of microorganisms and thus improving odor treatment efficiency. Furthermore, this design facilitates the replenishment of microorganisms in the second packing material, and the entire system is compact and easy to operate, saving floor space and enhancing operational convenience. Moreover, this design allows for convenient microbial replenishment by staff, and microbial cultivation and other operations can be carried out simultaneously with deodorization operations without requiring downtime, thereby improving deodorization efficiency and reducing operating costs.

[0059] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.

[0060] like Figures 1 to 8 The image shows an embodiment of the present invention, which discloses an odor treatment device, including a first tower 1 and a second tower 6. The first tower 1 is used for initial treatment of odor, and the second tower 6 is used for secondary treatment of odor.

[0061] In one embodiment, such as Figure 1 , Figure 2 As shown, an air inlet pipe 2 is connected to the top of the first tower body 1, a first water tank 3 is provided at the bottom of the first tower body 1, and a first packing 4 is provided inside the first tower body 1. At the same time, a first spraying element 5 is provided on the first tower body 1, which is used to extract the solution in the first water tank 3 and spray the solution onto the first packing 4.

[0062] In one embodiment, such as Figure 1 , Figure 3As shown, the top of the second tower body 6 is connected to an exhaust pipe 7, the bottom of the second tower body 6 is provided with a second water tank 8, and the interior of the second tower body 6 is provided with a second packing material 9. At the same time, the second tower body 6 is provided with a second spraying element 10, which is used to extract the solution in the second water tank 8 and spray the solution onto the second packing material 9.

[0063] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, an air intake channel 11 is provided between the first tower body 1 and the second tower body 6. One end of the air intake channel 11 is connected to the first tower body 1, and the other end is connected to the second tower body 6. At the same time, one end of the air intake channel 11 is located between the first packing 4 and the first water tank 3, and the other end is located between the second packing 9 and the second water tank 8.

[0064] In one embodiment, such as Figure 1 , Figure 4 As shown, a support plate 12 is horizontally arranged on the inner wall of the air intake channel 11, and support frames 13 are arranged on both sides of the support plate 12. The two ends of the support plate 12 and the two support frames 13 are sealed together using elastic materials such as rubber or latex, so that a trapezoidal storage space 14 is formed between the support plate 12 and the two support frames 13. At the same time, the storage space 14 is filled with coconut fiber filler 15 to serve as a microbial culture carrier.

[0065] In one embodiment, such as Figure 1 , Figure 4 As shown, the odor treatment device also includes a microbial culture component 16 and a drip irrigation component 17. The microbial culture component 16 is used to cultivate microbial solution. One end of the drip irrigation component 17 is connected to the microbial culture component 16 and the other end is located in the storage space 14, so that the microbial culture component 16 can transport the cultivated microbial solution to the coconut fiber filler 15 through the drip irrigation component 17.

[0066] In one embodiment, such as Figure 1 , Figure 4 , Figure 5 As shown, two support frames 13 are hinged to the support plate 12 respectively. A drive component 18 is provided in the air intake channel 11. The drive component 18 is used to control the two support frames 13 to move closer to each other and to squeeze the coconut fiber filler 15, thereby squeezing out the bacterial liquid inside the coconut fiber filler 15. When the odorous gas flows through the air intake channel 11, the squeezed bacterial liquid can be blown into the second water tank 8 by the odorous gas. When the second spray component 10 sprays the second filler 9, the second spray component 10 can spray the bacterial liquid onto the second filler 9 to replenish the microorganisms inside the second filler 9.

[0067] The odor treatment device in this embodiment can replenish the microorganisms within the second packing material 9, thereby ensuring the quantity of microorganisms within the second packing material 9 and improving the odor treatment effect. Simultaneously, this design facilitates the replenishment of microorganisms within the second packing material 9, and the replenishment can be carried out simultaneously with the deodorization operation without requiring shutdown, thus improving deodorization efficiency. Furthermore, by placing the coconut fiber packing material 15 within the air inlet channel 11, the microorganisms within the coconut fiber packing material 15 can first adapt to the odor, enabling them to stabilize the odor when subsequently entering the second packing material 9.

[0068] In one embodiment, such as Figure 1 , Figure 4 As shown, each support frame 13 has multiple air guide plates 19 fixed at an angle. The multiple air guide plates 19 are parallel to each other and are evenly arranged in the vertical direction. At the same time, the air guide plates 19 on the two support frames 13 are tilted in opposite directions, that is, the air guide plates 19 on the two support frames 13 are arranged symmetrically.

[0069] In one embodiment, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the support plate 12 is vertically slidably connected to the inner wall of the air intake channel 11. When the driving component 18 controls the two support frames 13 to move closer or further apart, the support plate 12 can slide vertically under the action of the two support frames 13. At this time, the angle between the air guide plate 19 and the horizontal plane changes, and the distance between the support plate 12 and the bottom wall of the air intake channel 11 changes, thereby changing the cross-sectional area of ​​the air intake channel 11 and thus adjusting the air intake volume. A specific example is as follows:

[0070] When the two support frames 13 are far apart, the angle between the air guide plate 19 and the horizontal plane decreases, meaning the channel between two adjacent air guide plates 19 becomes increasingly horizontal. This facilitates the entry of odorous gases into the coconut fiber filler 15. When the two support frames 13 are close together, the angle between the air guide plate 19 and the horizontal plane increases, meaning the channel between two adjacent air guide plates 19 becomes increasingly vertical. This hinders the entry of odorous gases into the coconut fiber filler 15, thus enabling control of the airflow into the coconut fiber filler 15. This allows staff to precisely control the cultivation and growth of microorganisms based on gas concentration and airflow.

[0071] Simultaneously, when the two support frames 13 move away from each other, the support plate 12 moves upward, thereby increasing the cross-sectional area of ​​the air intake channel 11. This increases the amount of odorous gas entering the second tower body 6. When the two support frames 13 move closer to each other, the support plate 12 moves downward, thereby decreasing the cross-sectional area of ​​the air intake channel 11. This reduces the amount of odorous gas entering the second tower body 6. Therefore, this design also allows for control of the airflow entering the second tower body 6, facilitating the second tower body 6's thorough treatment of odorous gases.

[0072] Furthermore, when the two support frames 13 approach each other, the support plate 12 moves downward, reducing the cross-sectional area of ​​the air intake channel 11. At this time, the air pressure of the odorous gas entering the second tower body 6 increases, which is more conducive to the odorous gas blowing the squeezed bacterial liquid into the second water tank 8, thereby ensuring the subsequent replenishment of microorganisms in the second packing 9, and thus ensuring the subsequent treatment effect of the odorous gas.

[0073] In one embodiment, such as Figure 5 , Figure 6 , Figure 7 As shown, the drive unit 18 includes two forward and reverse motors 181 that are horizontally slidably connected to the inner wall of the air intake channel 11. Each forward and reverse motor 181 has a gear 182 fixedly sleeved on its output shaft. A rack 183 is horizontally fixedly connected to the inner wall of the air intake channel 11, and the two gears 182 mesh with the rack 183 respectively.

[0074] In one embodiment, such as Figure 5 , Figure 6 , Figure 7 As shown, each of the two forward and reverse motors 181 has a drive rod 184 fixedly connected to it, and the two drive rods 184 are rotatably connected to the corresponding support frame 13. When the two forward and reverse motors 181 rotate synchronously in opposite directions, the motors 181 can drive the drive rods 184 to slide horizontally, and then the two support frames 13 can move closer or further apart, causing the support plate 12 to move vertically. When the two support frames 13 move closer together, the area of ​​the storage space 14 decreases, thereby achieving a squeezing effect on the coconut fiber filler 15, which in turn allows the bacterial solution inside the coconut fiber filler 15 to be squeezed out.

[0075] In one embodiment, such as Figure 1 , Figure 8 As shown, the microbial culture assembly 16 includes an incubator 161 and a storage tank 162, with the storage tank 162 used to store the microbial powder. A partition plate 20 is vertically fixed inside the incubator 161, dividing the incubator 161 into a dosing chamber 21 and a culture chamber 22. An overflow port 23 is provided at the upper end of the partition plate 20, and the overflow port 23 connects the dosing chamber 21 and the culture chamber 22.

[0076] In one embodiment, such as Figure 1 , Figure 8 As shown, the drip irrigation assembly 17 is connected to the dosing chamber 21, the storage tank 162 is connected to the culture chamber 22 through the feeding pipe 163, and the feeding pipe 163 is equipped with a powder pump 164 so that the powder pump 164 can draw the bacterial powder in the storage tank 162 into the culture chamber 22.

[0077] In one embodiment, such as Figure 1 , Figure 8 As shown, an air-liquid mixing pump 165 is connected to the incubator 161, and the discharge end of the air-liquid mixing pump 165 is connected to the culture chamber 22. The air-liquid mixing pump 165 is used to blow liquid and air into the incubator 161 simultaneously. At the same time, a stirrer 166 is installed in the culture chamber 22 to achieve mixing and stirring of the inoculum powder and liquid in the culture chamber 22.

[0078] In one embodiment, such as Figure 1 , Figure 8 As shown, the first water tank 3 is connected to a wet sludge pipe 167 and a compound humic acid pipe 168. The wet sludge pipe 167 is used to add wet sludge into the first water tank 3, and the compound humic acid pipe 168 is used to add humic acid compound fertilizer into the first water tank 3 to cultivate microorganisms in the wet sludge.

[0079] In one embodiment, such as Figure 1 , Figure 8 As shown, the solution in the first water tank 3 is divided into a supernatant layer 24, a gelatinous layer 25, and a sediment layer 26 from top to bottom. The microorganisms cultured in the sludge are located in the gelatinous layer 25. A suction pipe 169 is connected to the first water tank 3. One end of the suction pipe 169 is located in the gelatinous layer 25, and the other end is connected to the inlet of the gas-liquid mixing pump 165, so that the gelatinous layer 25 can be drawn into the culture chamber 22.

[0080] When the gas-liquid mixing pump 165 operates, the gelatinous layer 25, air, and inoculum powder simultaneously enter the culture chamber 22. At this time, the stirrer 166 mixes and stirs the inoculum powder and gelatinous layer 25. Then, the solution in the culture chamber 22 overflows into the dosing chamber 21 through the inlet hole. As the pressure in the dosing chamber 21 and the culture chamber 22 continuously increases, the solution in the dosing chamber 21 can then enter the coconut fiber filler 15 through the drip irrigation assembly 17 under negative pressure.

[0081] In one embodiment, such as Figure 6 , Figure 7 , Figure 8 As shown, the drip irrigation assembly 17 includes a drip irrigation pipe 171 horizontally arranged between two support frames 13, and the drip irrigation pipe 171 is fixed to the first tower body 1 or the second tower body 6. Meanwhile, multiple drip irrigation nozzles 172 are connected to the drip irrigation pipe 171, and the drip irrigation nozzles 172 are located inside the coconut coir filler 15.

[0082] In one embodiment, such as Figure 6 , Figure 7 , Figure 8 As shown, a drain pipe 173 is connected to the drip irrigation pipe 171, and the end of the drain pipe 173 away from the drip irrigation pipe 171 is connected to the bottom of the dosing chamber 21, so that the bacterial solution in the dosing chamber 21 can enter the drip irrigation pipe 171 through the drain pipe 173 and then be sprayed out through multiple drip irrigation nozzles 172.

[0083] In one embodiment, such as Figure 6 , Figure 7 , Figure 8 As shown, a pressure-sensing solenoid valve 174 is installed on the drain pipe 173. When the pressure inside the incubator 161 exceeds the preset value of the pressure-sensing solenoid valve, the pressure-sensing solenoid valve 174 automatically opens, allowing the bacterial solution to enter the drip irrigation pipe 171 through the drain pipe 173. In this embodiment, the preset value of the pressure-sensing solenoid valve 174 is 0.2 MPa. When the pressure inside the incubator 161 exceeds 0.2 MPa, the pressure-sensing solenoid valve 174 automatically opens, and the bacterial solution in the dosing chamber 21 is dripped into the coconut fiber packing 15 by the drip irrigation assembly 17.

[0084] Because the bacterial powder and gelatinous layer 25 are added in a timed and quantitative manner, and because the bacterial solution produces gases such as carbon dioxide due to metabolism and growth and proliferation in the incubator 161, the internal pressure of the incubator 161 increases. As a result, the bacterial solution in the incubator 161 can be released into the coconut fiber filler 15 at irregular intervals according to the fermentation situation. That is, when the pressure inside the incubator 161 exceeds the set value, the bacterial solution is immediately added into the coconut fiber filler 15.

[0085] In this embodiment, when the gel layer 25, air, and bacterial powder simultaneously enter the culture chamber 22, a small amount of air is introduced to allow the bacterial strain to adapt to a low-oxygen environment, preparing it for the subsequent entry of the bacterial strain into the anoxic environment of the second tower 6. Simultaneously, some gas from the incubator 161 also enters the drip irrigation assembly 17; the air expulsion process also reduces the risk of clogging the drip irrigation nozzles.

[0086] In one embodiment, such as Figure 1 , Figure 6 , Figure 7 As shown, the drip irrigation nozzle 172 is set at an angle, and the drain end of the drip irrigation nozzle 172 faces the second water tank 8. When some of the gas in the incubator 161 also enters the drip irrigation assembly 17 and is discharged through the drip irrigation nozzle, the gas can generate a blowing force in the inclined direction on the bacterial liquid. When the bacterial liquid is squeezed out, the force of the gas can help the bacterial liquid be stably blown into the second water tank 8.

[0087] In one embodiment, such as Figure 1 , Figure 3 As shown, a yucca extract pipe 27 is connected to the second water tank 8. The yucca extract pipe 27 is used to add yucca extract powder to the second water tank 8 to improve the activity of microorganisms in the second water tank 8. At the same time, when the second spray unit 10 sprays the second packing material 9, it can spray the nutrient solution containing yucca extract powder onto the second packing material 9 to promote the activity of microorganisms in the second packing material 9, thereby improving the odor treatment effect.

[0088] In one embodiment, such as Figure 1 , Figure 2 As shown, the first spraying component 5 includes a first spray pipe 51, which is disposed on the top wall of the first tower body 1. Multiple first spray heads 52 are connected to the first spray pipe 51, and these first spray heads 52 are respectively located above the first packing 4. A first spray pump 53 is connected to the first water tank 3, and the inlet end of the first spray pump 53 is immersed in the supernatant layer 24. Simultaneously, the outlet end of the first spray pump 53 is connected to a first delivery pipe, which is connected to the first spray pipe 51.

[0089] In one embodiment, such as Figure 1 , Figure 3 As shown, the second spray component 10 includes a second spray pipe 101, which is disposed on the top wall of the second tower body 6. Multiple second spray heads 102 are connected to the second spray pipe 101, and these second spray heads 102 are respectively located above the second packing 9. A second spray pump 103 is connected to the second water tank 8, with its inlet end connected to the second water tank 8. Simultaneously, the outlet end of the second spray pump 103 is connected to a second delivery pipe, which is connected to the second spray pipe 101.

[0090] The odor treatment device in this embodiment can replenish the microorganisms within the second packing material 9, thereby ensuring the quantity of microorganisms within the second packing material 9 and improving the odor treatment effect. Simultaneously, this design facilitates the replenishment of microorganisms within the second packing material 9, and the entire equipment is compact and easy to operate, saving floor space and improving operational convenience. Furthermore, this design allows for convenient replenishment of microorganisms by staff, and microbial cultivation and other operations can be carried out simultaneously with the deodorization operation without requiring downtime, thus improving deodorization efficiency and reducing operating costs.

[0091] This embodiment also discloses an odor treatment method using the above-described odor treatment device, which includes the following steps:

[0092] S1, introduce the odor into the air inlet pipe 2, and at the same time add wet sludge and humic acid compound fertilizer into the first water tank 3 to cultivate microorganisms in the wet sludge, thereby achieving the first targeted cultivation of microorganisms. Meanwhile, add yucca extract powder to the second water tank 8.

[0093] S2, the gelatinous layer 25 in the first water tank 3 is extracted into the microbial culture component 16, and microbial powder is added into the microbial culture component 16. The solution and microbial powder are mixed and stirred by the stirrer 166, thereby realizing the second directional culture of microorganisms.

[0094] S3, the bacterial solution in the microbial culture component 16 is transported to the coconut fiber filler 15 through the drip irrigation component 17 so that the microorganisms can undergo a third directional culture in the coconut fiber filler 15.

[0095] S4, the coconut fiber filler 15 is squeezed by two support frames 13 and multiple air guide plates 19, causing the bacterial liquid inside the coconut fiber filler 15 to be squeezed out. At this time, the odorous air flows through the air intake channel 11, and then the odorous air blows the squeezed-out bacterial liquid into the second water tank 8. At the same time, when the second spraying component 10 sprays the second filler 9 layer, the bacterial liquid and the nutrient solution containing yucca extract powder are sprayed together on the second filler 9 to replenish the microorganisms inside the second filler 9.

[0096] S5. Change the water in the first water tank 3 and the second water tank 8. The water in the first water tank 3 is changed every 6 hours, replacing 1 / 3 of the water each time. The water in the second water tank 8 is changed every 12 hours, replacing 1 / 3 of the water each time. At the same time, the amount of wet sludge and humic acid compound fertilizer in the first water tank 3 is 100g and 100ml respectively, and both are added every hour. The amount of yucca extract in the second water tank 8 is 100g / m3 of drainage volume, and it is added once a day (for example, if the second water tank 8 drains 3m3 of water per day, the amount of yucca extract to be added is 100×3=300g).

[0097] As can be seen from the above process, this device can be used to cultivate microorganisms and replenish microorganisms in the second packing 9 in a timely manner, thereby ensuring the quantity and activity of microorganisms in the second packing 9 and thus ensuring the treatment effect of odor.
