Description

Technical Field

[0001] This application relates to the technical field of soil environmental prevention and control, for example, to a device for treating soil environment based on microorganisms and its control method. Background Art

[0002] Soil is an important resource for human survival. In recent years, the booming development of agriculture has caused a large amount of soil pollution. For example, various agricultural plastic films are widely used as greenhouse and mulch covers. If not properly treated, a large number of residual film fragments will be scattered in the fields, causing white pollution in farmland. In addition, waste crops (straw, crop roots, stems, and leaves) rot directly in the soil without treatment, which is likely to produce stinky liquids and odors. All of the above will cause varying degrees of damage to the soil, resulting in the soil being unable to provide nutrients for the growth of crops, and even polluting the air environment, which is not conducive to the sustainable development of the agricultural economy.

[0003] Currently, the treatment methods for soil pollutants such as plastic films and waste crops mostly adopt incineration or landfill. The incineration method will produce smoke and harmful gases, causing air pollution. Landfill is an effective method for treating soil pollutants and also the final treatment method for the residues of all waste treatment processes. Usually, soil pollutants are put into the excavated landfill pits, and then the required microorganisms are sprayed into the landfill pits to degrade the soil pollutants to achieve the purpose of reduction. Although soil pollutants can be centrally treated, during the treatment process of soil pollutants, it is impossible to always keep the soil pollutants in close contact with the microorganisms, resulting in the microorganisms being unable to continuously and efficiently degrade the pollutants, reducing the treatment efficiency, and being unable to effectively and thoroughly treat the harmful gases such as odors generated during the degradation process, reducing the treatment effect, and causing the harmful gases to be discharged into the atmospheric environment, polluting the air environment.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related technologies:

[0005] It is impossible to always keep the soil pollutants in close contact with the microorganisms, resulting in the microorganisms being unable to continuously and efficiently degrade the pollutants, reducing the treatment efficiency, and being unable to effectively and thoroughly treat the harmful gases such as odors generated during the degradation process, reducing the treatment effect, and causing the harmful gases to be discharged into the atmospheric environment, polluting the air environment.

[0006] It should be noted that the information disclosed in the above background art section is only used to strengthen the understanding of the background of this application. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not a general review, nor is it intended to identify key / important elements or delineate the scope of protection of these embodiments. Instead, it serves as a preface to the detailed description that follows.

[0008] Embodiments of the present disclosure provide a device for treating soil environment based on microorganisms and its control method, which can make the pollutants in the box come into close contact with the microbial degradation plates, contribute to promoting the rapid decomposition of pollutants, improving the degradation efficiency of pollutants, and ensuring that no harmful gases are discharged into the atmosphere during the treatment of pollutants, enhancing the treatment effect while strengthening the protection of the air environment.

[0009] In some embodiments, a device for treating soil environment based on microorganisms includes: a box body, a microbial delivery component, a pressing cover plate, a detection component, and a controller component. The box body has a rectangular structure and has an upward delivery port. The box body is used to hold soil pollutants. A plurality of microbial degradation plates are evenly arranged in the box body. The plurality of microbial degradation plates divide the soil pollutants in the box body into multiple pollutant treatment layers according to a set thickness. Among them, each microbial degradation plate is coated with microorganisms; the microbial delivery component includes a delivery pipe and a microbial incubator. The delivery pipe is a hollow pipe body structure with open ends at both ends and through holes on the lower side wall. The delivery pipe is vertically inserted into the box body and penetrates through the microbial degradation plates and pollutant treatment layers in the box body; the microbial incubator cultivates the required microorganisms, and the microbial incubator is connected to the top end of the delivery pipe; the pressing cover plate is movably arranged above the delivery port of the box body and is located below the connection position of the microbial incubator and the delivery pipe. A perforation corresponding to the delivery pipe is provided on the pressing cover plate. When the pressing cover plate moves downward, it provides a vertically downward pressure for the pollutants stored in the box body and the microbial degradation plates; the detection component is connected to the delivery pipe and is used to detect the gas emission rate of the delivery pipe; the controller component is connected to the pressing cover plate, the microbial incubator, and the detection component. The controller component is used to continuously control the pressing cover plate to move downward and, according to the gas emission rate of the delivery pipe, control the microbial incubator to periodically adjust the amount of microorganisms it delivers into the delivery pipe.

[0010] In some embodiments, a control method for a device for treating soil environment based on microorganisms includes:

[0011] Continuously control the pressing cover plate to move downward to provide a vertically downward pressure for the pollutants stored in the box body and the microbial degradation plates, and control the microbial incubator to deliver microorganisms into the delivery pipe;

[0012] Obtain the gas emission rate of the delivery pipe;

[0013] Control the microbial incubator to periodically adjust the amount of microorganisms it puts into the dosing pipe according to the gas emission rate of the dosing pipe.

[0014] The device for treating soil environment based on microorganisms and its control method provided by the embodiments of the present disclosure can achieve the following technical effects:

[0015] Use the pressing cover plate to provide a vertically downward pressure on the pollutants stored in the box body and the microbial degradation plate, which can make the pollutants in the box body be in close contact with the microbial degradation plate, help to promote the rapid decomposition of pollutants, and improve the pollutant degradation efficiency. During the decomposition process of soil pollutants, the gas generated by degradation can be discharged through the dosing pipe, and according to the gas emission rate of the dosing pipe, control the microbial incubator to periodically adjust the amount of microorganisms it puts into the dosing pipe, so that the form of microorganism dosing meets the changes in harmful gases generated during the decomposition process of pollutants, and the microorganisms put in are sufficient to completely decompose the harmful gases, ensuring that during the pollutant treatment process, harmful gases can be completely prevented from being discharged into the atmosphere, improving the treatment effect while enhancing the protection of the air environment. Among them, when treating waste crops, organic matters such as straw, crop roots, stems, and leaves will quickly ferment in the box body under the action of microorganisms and finally form natural fertilizers on the microbial degradation plate, realizing on-site utilization of waste. After taking out the microbial degradation plate, the fertilizers on it can be evenly spread around the crops as organic mulch, which has a good effect on improving the soil environment.

[0035] Combine Figure 1-3As shown in the figure, an embodiment of the present disclosure provides a device for treating soil environment based on microorganisms, including: a box body 100, a microorganism feeding component 300, a pressing cover plate 400, a detection component 500, and a controller component 600. The box body 100 has a rectangular structure and has an upward feeding port. The box body 100 is used for containing soil pollutants. A plurality of microorganism degradation plates 200 are evenly arranged in the box body 100. The plurality of microorganism degradation plates 200 divide the pollutants in the box body 100 into a plurality of soil pollutant treatment layers according to a set thickness. Among them, each microorganism degradation plate 200 is coated with microorganisms; the microorganism feeding component 300 includes a feeding pipe 301 and a microorganism incubator 302. The feeding pipe 301 is a hollow pipe body structure with openings at both ends and through holes on the lower side wall. The feeding pipe 301 is vertically inserted into the box body 100, and the feeding pipe 301 penetrates through the microorganism degradation plates 200 and the pollutant treatment layers in the box body 100; the microorganism incubator 302 cultivates the required microorganisms, and the microorganism incubator 302 is connected to the top end of the feeding pipe 301; the pressing cover plate 400 is movably arranged above the feeding port of the box body 100, and the pressing cover plate 400 is located below the connection position of the microorganism incubator 302 and the feeding pipe 301. A perforation 401 corresponding to the feeding pipe 301 is provided on the pressing cover plate 400. When the pressing cover plate 400 moves downward, it provides a vertically downward pressure for the pollutants stored in the box body 100 and the microorganism degradation plates 200; the detection component 500 is connected to the feeding pipe 301 and is used for detecting the gas emission speed of the feeding pipe 301; the controller component 600 is connected to the pressing cover plate 400, the microorganism incubator 302, and the detection component 500. The controller component 600 is used for continuously controlling the pressing cover plate 400 to move downward, and controlling the microorganism incubator 302 to periodically adjust the feeding amount of microorganisms fed into the feeding pipe 301 according to the gas emission speed of the feeding pipe 301.

[0036] Using the device for treating soil environment based on microorganisms provided by the embodiments of the present disclosure, the pressing cover plate 400 is used to provide a vertically downward pressure to the pollutants stored in the box body 100 and the microbial degradation plate 200, which can make the pollutants in the box body 100 be in close contact with the microbial degradation plate 200, helping to promote the rapid decomposition of pollutants and improve the pollutant degradation efficiency. During the decomposition process of soil pollutants, the gas generated by degradation can be discharged through the delivery pipe 301, and according to the gas emission speed of the delivery pipe 301, the microbial incubator 302 is controlled to periodically adjust the amount of microorganisms it delivers into the delivery pipe 301, so that the delivery form of microorganisms meets the changes in harmful gases generated during the decomposition process of pollutants, ensuring that the delivered microorganisms are sufficient to completely decompose the harmful gases, and completely preventing harmful gases from being discharged into the atmosphere during the treatment of pollutants, improving the treatment effect while enhancing the protection of the air environment. Among them, when treating waste crops, organic matters such as straws, crop roots, stems, and leaves will quickly ferment in the box body under the action of microorganisms, and finally form natural fertilizers on the microbial degradation plate 200, realizing on-site utilization of waste. After the microbial degradation plate 200 is taken out, the fertilizers on it can be evenly spread around the crops as organic mulch, which has a good effect on improving the soil environment.

[0037] It can be understood that when treating soil pollutants, a landfill pit for soil pollutants can be pre-excavated, the box body 100 can be placed in the landfill pit, and then the soil pollutants can be concentrated and put into the box body 100 for treatment of soil pollutants, or it can be directly installed on the ground surface for use, which will not be elaborated here.

[0038] Optionally, the microbial degradation plate 200 is made of a fiber material and has a rectangular mesh structure. In this way, microorganisms can better adhere to the microbial degradation plate 200, improving the stability of microbial adhesion, ensuring the amount of microorganisms used, and avoiding the situation that the microorganisms fall off and affect the decomposition efficiency of pollutants.

[0039] Optionally, multiple microbial degradation plates 200 are all horizontally arranged in the box body 100, and the multiple microbial degradation plates 200 are arranged at equal intervals along the height direction of the box body 100. In this way, the multiple microbial degradation plates 200 are more evenly arranged in the box body 100, and the pollutants in the box body 100 can be stratified to efficiently and quickly decompose the pollutants.

[0040] Optionally, a sealing gasket is arranged in the through hole 401. In this way, the sealing performance is enhanced, and the situation that the gas generated in the box body 100 flows into the atmosphere through the gap between the pressing cover plate 400 and the delivery pipe 301 is avoided.

[0041] Optionally, the microbial degradation plate 200 is provided with a notch portion 201, and the notch portion 201 corresponds to the delivery pipe 301. The notch portion 201 has a strip structure and there are multiple of them. Each notch portion 201 corresponds to multiple delivery pipes 301 that are in the same straight line. In this way, it is convenient to install the microbial degradation plate 200, reduce the mutual influence between the microbial degradation plate 200 and the delivery pipe 301, and improve the convenience of installation.

[0042] It should be noted that in specific implementation, the number of microbial degradation plates 200 used can be determined by the volume of pollutants in the box body 100. When the volume of pollutants is large, a larger number of microbial degradation plates 200 can be selected to divide the pollutants in the box body 100 into multiple pollutant treatment layers with relatively smaller volumes; while when the volume of pollutants is small, a smaller number of microbial degradation plates 200 can be selected to avoid waste and save costs while ensuring efficient degradation of pollutants. Of course, the microbial degradation plates 200 can also be set according to the height of the pollutants. For example, a microbial degradation plate 200 is inserted into the pollutants every 15 - 20 cm.

[0043] Optionally, there are multiple delivery pipes 301. The multiple delivery pipes 301 are uniformly arranged in the box body 100 in the vertical direction. Fibrous filaments are filled in the delivery pipes 301, and the multiple delivery pipes 301 are all connected to the microbial incubator 302 through the delivery pipe 303. In this way, by using the multiple delivery pipes 301, the gas generated in the box body 100 can be quickly discharged, avoiding the situation that the internal air pressure of the box body 100 rises due to a large amount of gas in the box body 100, which affects the efficiency of microbial decomposition of pollutants. And the fibrous filaments filled in the delivery pipes 301 can keep the microorganisms stably in the delivery pipes 301, and the delivery pipe 303 can ensure the stable delivery of microorganisms into the delivery pipes 301.

[0044] Optionally, the delivery pipe 301 has a part inserted into the box body 100 and a part protruding above the delivery port, and through holes are opened on the part of the delivery pipe 301 inserted into the box body 100. In this way, it is ensured that the gas in the box body 100 can smoothly enter the delivery pipe 301 and be quickly discharged through the delivery pipe 301.

[0045] Optionally, the microbial incubator 302 is connected to the side wall of the box body 100 through the mounting frame 103, and the microbial incubator 302 is suspended on one side above the pressure cover plate 400. Among them, the mounting frame 103 has an inverted U-shaped structure, and its opposite side walls are in the same plane as the opposite side walls of the box body 100. In this way, it is convenient to install the microbial incubator 302 while ensuring the stability of the installation of the microbial incubator 302.

[0046] Optionally, the distance between the microbial incubator 302 and the plane where the feeding port is located is greater than or equal to half of the height of the box body 100 and less than or equal to the height of the box body 100. In this way, when the pressing cover plate 400 opens the box body 100, there is enough distance between them, reducing the impact on the pollutants when they are put into the box body 100 and facilitating the smooth putting of the pollutants into the box body 100.

[0047] Optionally, there are multiple delivery pipes 303, and each delivery pipe 303 is communicated with multiple feeding pipes 301. Preferably, three delivery pipes 303 are provided, and the number of feeding pipes 301 is four times that of the delivery pipes 303. Each delivery pipe 303 is connected to four feeding pipes 301 in the same straight line. In this way, the structural design is more reasonable. On the premise of ensuring rapid gas discharge, the installation space can be reasonably utilized, and the microorganisms can be reasonably distributed into each feeding pipe 301 according to the demand of the gas to be treated, adjusting the feeding form of the microorganisms to ensure that the microorganisms can efficiently decompose harmful gases and effectively inhibit the generation of malodors.

[0048] Optionally, a connection hole is provided on the side wall of each feeding pipe 301, and the delivery pipe 303 is communicated with the side wall of the feeding pipe 301 through the connection hole. In this way, the impact of the microorganism feeding process on the gas discharge process is reduced, ensuring that both the feeding of microorganisms and the discharge of gas can proceed smoothly and stably.

[0049] Optionally, multiple feeding pipes 301 in the same straight line and multiple delivery pipes 303 are arranged alternately above the pressing cover plate 400. In this way, the arrangement of the feeding pipes 301 and the delivery pipes 303 above the box body 100 is more neat and coordinated, enhancing the aesthetic appearance of the overall structure and facilitating installation and disassembly.

[0050] Optionally, a on-off valve that can be controlled to open or close is provided in the connection hole, and the on-off valve is used to control the on-off between the delivery pipe 303 and the feeding pipe 301. In this way, it is convenient to control the feeding position of the microorganisms and the feeding amount of microorganisms in each feeding pipe 301, so that the feeding form of the microorganisms can be controlled according to the difference in the gas discharge speed in each feeding pipe 301, and then the harmful gases in each feeding pipe 301 can be better treated, ensuring that the harmful gases discharged from each feeding pipe 301 can be comprehensively purified before being discharged.

[0051] Optionally, each on-off valve is independently controlled. In this way, by independently controlling the on-off between each feeding pipe 301 and the delivery pipe 303, it is convenient to control the feeding position of the microorganisms and the feeding amount of microorganisms in each feeding pipe 301.

[0052] Optionally, the same type of microorganism is coated on each microbial degradation plate 200, or the microbial degradation plates 200 are partially coated with microorganisms for degrading pollutants, and the remaining part is coated with microorganisms that can decompose harmful gases. In this way, the form of treating pollutants is diversified, which can not only efficiently decompose pollutants, but also treat the harmful gases generated during the decomposition of pollutants, enabling the simultaneous decomposition of pollutants and gases, ensuring efficient treatment of pollutants while better suppressing the generation of odors.

[0053] Optionally, the microorganism incubator 302 can transport microorganisms to the microbial degradation plate 200 through the feeding pipe 301. In this way, the microbial degradation plate 200 can be equipped with a sufficient amount of microorganisms for pollutant treatment, ensuring the high efficiency of pollutant degradation.

[0054] Optionally, the pressing cover plate 400 is connected to the side wall of the box body 100 through the support frame 101, and the support frame 101 is in an L-shaped structure. A driving cylinder 102 is connected between the pressing cover plate 400 and the part of the support frame 101 above the box body 100, and the driving cylinder 102 is used to drive the pressing cover plate 400 to move longitudinally. In this way, the pressing cover plate 400 can be installed more stably, and the driving cylinder 102 can stably drive the movement of the pressing cover plate 400, ensuring the stable opening of the box body 100 and the extrusion of pollutants in the box body 100.

[0055] Optionally, the support frame 101 is located on the center line of the box body 100. In this way, it is ensured that the pressing cover plate 400 is stably driven to move into the box body 100, ensuring the balance of pressure on the pollutants, so that the microbial degradation plate 200 can fully contact the pollutants and more efficiently degrade the pollutants.

[0056] Optionally, the device for treating soil environment based on microorganisms further includes: a liquid collection tank 700. The liquid collection tank 700 is arranged on one side of the box body 100 and is connected to the bottom of the box body 100. In this way, the liquid collection tank 700 can be used to collect the leachate generated after the decomposition of pollutants in the box body 100, which can not only avoid the continuous generation of harmful gases caused by the long-term storage of leachate in the box body 100, but also prevent the leachate from invading the soil and damaging the soil, resulting in reduced crop yields and lower quality of agricultural products, enhancing the protection of the soil environment.

[0057] Optionally, a first drain port is opened at the bottom of the side of the box body 100 where the liquid collection tank 700 is installed. The box body 100 is connected to the liquid collection tank 700 through the drain port, and a second drain port is opened on the liquid collection tank 700. In this way, the smoothness of drainage is ensured, and the leachate generated in the box body 100 can be smoothly discharged into the liquid collection tank 700.

[0058] Optionally, an infusion pump that can be controlled to start and stop is installed between the box body 100 and the liquid collection tank 700. The infusion pump is used to transport the liquid at the bottom of the box body 100 to the liquid collection tank 700. In this way, the infusion pump provides power for the transportation of the liquid, which helps to quickly discharge the leachate generated in the box body 100. When treating waste crops, it can avoid the situation that the leachate remains in the box body 100 and affects the fermentation of organic matter.

[0059] In some other embodiments, as Figure 4-5 shown, optionally, microorganisms for degrading pollutants are cultured in the microorganism incubator 302. The device for treating the soil environment based on microorganisms further includes: a movable bracket 104 and a gas collection tank 800. The movable bracket 104 is fixedly connected to the side wall of the box body 100 and is located on the opposite side of the support frame 101. The gas collection tank 800 is movably arranged on the movable bracket 104, and a plurality of gas collection pipes 801 are connected to one side surface of the gas collection tank 800 facing the feeding pipe 301. When the gas collection tank 800 moves to the first position, the gas collection pipe 801 is communicated with the top of the feeding pipe 301. When moving to the second position, the gas collection pipe 801 is separated from the feeding pipe 301. In this way, microorganisms can be transported to the pollutant treatment layer and the microorganism degradation plate 200 in the box body 100 through the microorganism incubator 302, which helps to provide a sufficient amount of microorganisms to promote the rapid decomposition of pollutants, improve the pollutant decomposition efficiency, save the decomposition time, and install the gas collection tank 800. By moving the gas collection tank 800 to connect the gas collection pipe 801 with the top of the feeding pipe 301, the gas collection tank 800 can collect the harmful gases generated in the box body 100 due to the decomposition of pollutants, avoiding the situation that the gas enters the atmosphere and pollutes the environment, which is more environmentally friendly.

[0060] Optionally, the connection form between the plurality of gas collection pipes 801 and the plurality of feeding pipes 301 is the same as the connection form between the plurality of conveying pipes 303 and the plurality of feeding pipes 301. In this way, the arrangement of the plurality of gas collection pipes 801 and the plurality of conveying pipes 303 above the box body 100 is more coordinated and neat, which is easy to install and convenient to control, reducing the mutual influence between the plurality of gas collection pipes 801 and the plurality of conveying pipes 303, and ensuring that the gas collection process can be carried out in an orderly manner.

[0061] Optionally, when the gas collection pipe 801 is communicated with the top of the feeding pipe 301, the gas collection pipe 801 is hermetically connected to the feeding pipe 301. In this way, the sealing performance is enhanced, and the situation of gas leakage is avoided.

[0062] It can be understood that the hermetic connection can adopt the existing technology, such as using rubber rings for sealing, etc. The specific structure and its sealing form will not be elaborated here.

[0063] Optionally, an exhaust pipe 802 is provided on the air collecting box 800. In this way, since the waste gas generated by the decomposition of pollutants can be used for power generation, the exhaust pipe 802 is provided and connected to an external power generation device according to the usage requirements, and the waste gas is used for power generation to achieve the purpose of waste utilization and energy conservation.

[0064] In some other embodiments, optionally, an insertion opening is formed on one side surface of the box body 100, and a driving box is provided on the side where the insertion opening is formed. A plurality of microbial degradation plates 200 are evenly arranged in the driving box, and a plurality of driving parts are arranged in the driving box. Each driving part is correspondingly connected to a microbial degradation plate 200. The driving part is used to drive the microbial degradation plate 200 to move into or out of the box body 100 through the insertion opening. When driving the microbial degradation plate 200 to move into the box body 100, the pollutants in the box body 100 can be separated into a plurality of pollutant treatment layers according to a set thickness. In this way, the method of putting the microbial degradation plates 200 into the box body 100 is automated, and the microbial degradation plates 200 can be automatically controlled to enter the box body 100 according to the treatment requirements of pollutants, and the pollutants in the box body 100 are separated into a plurality of pollutant treatment layers according to a set thickness, so as to efficiently and quickly treat pollutants.

[0065] Optionally, when the pressing cover plate 400 is in the driving box, one end of the pressing cover plate 400 plugs the insertion opening on the side surface of the box body 100. In this way, it is avoided that pollutants enter the driving box during the pollutant feeding process.

[0066] Combined Figure 6 As shown, a control method for a device for microbial treatment of soil environment provided by an embodiment of the present disclosure includes:

[0067] S01, continuously control the pressing cover plate to move downward to provide a vertically downward pressure for the pollutants and microbial degradation plates stored in the box body, and control the microbial incubator to put microorganisms into the feeding pipe;

[0068] S02, obtain the gas emission rate of the feeding pipe;

[0069] S03, according to the gas emission rate of the feeding pipe, control the microbial incubator to periodically adjust the feeding amount of microorganisms put into the feeding pipe.

[0070] Using the control method for the device for microbial treatment of soil environment provided by the embodiments of the present disclosure, a vertical downward pressure is provided to the pollutants stored in the box body 100 and the microbial degradation plate 200 by using the pressing cover plate 400, which can make the pollutants in the box body 100 be in close contact with the microbial degradation plate 200, contribute to promoting the rapid decomposition of pollutants, and improve the pollutant degradation efficiency. During the decomposition process of soil pollutants, the gas generated by degradation can be discharged through the discharge pipe 301, and according to the gas discharge speed of the discharge pipe 301, the microbial incubator 302 is controlled to periodically adjust the amount of microorganisms it discharges into the discharge pipe 301, so that the discharge form of microorganisms meets the change of harmful gases generated during the decomposition process of pollutants, and the discharged microorganisms are sufficient to completely decompose the harmful gases, ensuring that during the treatment of pollutants, harmful gases can be completely prevented from being discharged into the atmosphere, improving the treatment effect while enhancing the protection of the air environment. Among them, when treating waste crops, organic matters such as straws, crop roots, stems, and leaves will rapidly ferment in the box under the action of microorganisms and finally form natural fertilizers on the microbial degradation plate 200, realizing on-site utilization of waste. After the microbial degradation plate 200 is taken out, the fertilizers on it can be evenly spread around the crops as organic mulches, which has a good effect on improving the soil environment.

[0071] Optionally, before continuously controlling the pressing cover plate to move downward to provide a vertical downward pressure to the pollutants stored in the box body and the microbial degradation plate, it includes: obtaining the instantaneous resistance received by the pressing cover plate when the pollutants are displaced by the pressing cover plate, and using the instantaneous resistance as the initial pressure when the pressing cover plate presses on the pollutant treatment layer in the box body; controlling the driving cylinder to drive the pressing cover plate to move downward with the initial pressure. In this way, since the pollutants are decomposed in the box body, the volume of the pollutants gradually decreases, and thus the resistance received by the pressing cover plate also gradually decreases. Using the instantaneous resistance received by the pressing cover plate when starting to press the pollutant treatment layer as the initial pressure can ensure that the pressing cover plate continuously moves downward, so as to ensure that the pollutant treatment layer and the microbial degradation plate are always in close contact, which helps to always decompose pollutants quickly and efficiently.

[0072] Optionally, controlling the driving cylinder to drive the pressing cover plate to move downward with the initial pressure includes: controlling the driving cylinder to continuously drive the pressing cover plate to move downward with the initial pressure. In this way, ensuring that the pollutant treatment layer and the microbial degradation plate are always in close contact helps to always decompose pollutants quickly and efficiently.

[0073] Optionally, while obtaining the gas emission rate of the delivery pipe, the gas component composition flowing out of the delivery pipe is detected, and a warning message is issued when the gas components contain harmful gas components. In this way, by issuing a warning message when the gas components contain harmful gas components, it is convenient for the staff to timely understand the gas components discharged into the atmosphere, so as to make timely adjustments and reduce the pollution of the atmosphere by harmful gases.

[0074] Optionally, controlling the microorganism incubator to deliver microorganisms into the delivery pipe includes: determining the total amount of pollutants in the box; determining the amount of gas generated during the decomposition of pollutants according to the total amount of pollutants in the box; and controlling the microorganism incubator to deliver microorganisms into the delivery pipe according to the corresponding relationship between the amount of gas generated during the decomposition of pollutants and the amount of microorganism delivery. In this way, it is ensured that the microorganisms can comprehensively and efficiently process the harmful gases generated during the decomposition of pollutants, and the situation of harmful gases entering the atmosphere is avoided.

[0075] Optionally, controlling the microorganism incubator to deliver microorganisms into each delivery pipe includes: detecting the pollutant density near each delivery pipe; and controlling the microorganism incubator to deliver microorganisms into each delivery pipe according to the corresponding relationship between the pollutant density and the amount of microorganism delivery, wherein the pollutant density is positively correlated with the amount of microorganism delivery. In this way, since the pollutant density is high, more harmful gases are generated during decomposition, so according to the corresponding relationship, an appropriate amount of microorganisms can be reasonably delivered to each delivery pipe to ensure that no odor is generated in each delivery pipe.

[0076] Optionally, controlling the microorganism incubator to deliver microorganisms into each delivery pipe includes: determining the target position of microorganism delivery; and controlling the on-off valve at this position to open and the on-off valves at other positions to close according to the target position. In this way, the microorganisms can be accurately delivered to better inhibit the generation of harmful gases in each delivery pipe.

[0077] Optionally, obtaining the gas emission rate of the delivery pipe includes obtaining the gas emission rate of each delivery pipe. In this way, since the gas flows upward randomly and the pollutant density at the corresponding position of each delivery pipe is different, the gas emission rate of each delivery pipe is also different. Therefore, by detecting the gas emission rate of each delivery pipe and adjusting the amount of microorganisms delivered to each delivery pipe according to the gas emission rate of each delivery pipe, it is possible to completely decompose all the harmful gases in each delivery pipe.

[0078] Optionally, the gas emission rate of the dosing pipe is positively correlated with the dosing amount of microorganisms. In this way, since the faster the gas emission rate of the dosing pipe, the faster the pollutants are decomposed in the box, the greater the amount of harmful gases generated. Therefore, the gas emission rate of the dosing pipe is positively correlated with the dosing amount of microorganisms. When the gas emission rate of the dosing pipe increases, the dosing amount of microorganisms can be increased to achieve the purpose of comprehensively and thoroughly decomposing harmful gases. When the gas emission rate of the dosing pipe decreases, there is no need to increase microorganisms, and the already dosed amount of microorganisms can be used to efficiently treat harmful gases.

[0079] It can be understood that the positive correlation between the gas emission rate of the dosing pipe and the dosing amount of microorganisms means that the faster the gas emission rate of the dosing pipe, the greater the dosing amount of microorganisms; the slower the gas emission rate of the dosing pipe, the smaller the dosing amount of microorganisms.

[0080] Optionally, controlling the microorganism incubator to periodically adjust the dosing amount of microorganisms it doses into the dosing pipe according to the gas emission rate of the dosing pipe includes: when the gas emission rate of the dosing pipe gradually increases, based on the initial dosing amount of microorganisms, controlling the microorganism incubator to multiply the dosing amount of microorganisms; at the instant when the gas emission rate of the dosing pipe starts to decline, controlling the microorganism incubator to stop dosing microorganisms. In this way, the dosing amount of microorganisms can meet the changes in harmful gases generated during the decomposition of pollutants, and thus the dosed microorganisms can fully decompose harmful gases. When the gas emission rate of the dosing pipe decreases, it indicates that the generation amount of harmful gases also decreases. Therefore, there is no need to increase microorganisms, and the already dosed amount of microorganisms can be used to efficiently treat harmful gases.

[0081] In some other embodiments, optionally, when the microorganisms for degrading pollutants are cultured in the microorganism incubator and the microorganisms coated on the microorganism degradation plate are also for degrading pollutants, control the gas collection box to move to the first position so that the gas collection pipeline is connected to the top of the dosing pipe. In this way, the gas collection box can collect the harmful gases generated due to the decomposition of pollutants in the box, avoiding the situation of gas entering the atmosphere and polluting the environment, which is more environmentally friendly, and the collected gas can also be used as a power generation source.

[0082] Optionally, continuously control the pressing cover plate to move downward to provide a vertically downward pressure on the pollutants stored in the box and the microorganism degradation plate, and start the infusion pump while controlling the microorganism incubator to dose microorganisms into the dosing pipe. In this way, the liquid collection box can be used to collect the leachate generated after the decomposition of pollutants in the box, avoiding the continuous generation of harmful gases due to the long-term storage of leachate in the box.

[0083] Optionally, continuously control the pressing cover plate to move downward to provide a vertically downward pressure on the pollutants and the microbial degradation plate stored in the box, and before controlling the microbial incubator to put microorganisms into the feeding tube, include: controlling the driving part to drive the microbial degradation plate to move into the box, and separating the pollutants in the box into multiple pollutant treatment layers according to a set thickness. In this way, the method of putting the microbial degradation plate into the box is automated, and the microbial degradation plate can be automatically controlled to enter the box according to the treatment requirements of pollutants, and the pollutants in the box are separated into multiple pollutant treatment layers according to a set thickness, so as to efficiently and quickly treat the pollutants.
