Abstract
Description
Technical Field
[0001] This invention relates to the field of waste treatment technology, specifically to a household waste recycling and disposal classification system. Background Technology
[0002] Waste recycling and disposal systems typically consist of two independent components: recycling containers and back-end disposal facilities. The recycling containers only collect waste; after being mixed together, the waste must be manually transported to the back-end facilities for sorting and disposal. In existing technologies, there is a lack of direct connection between the recycling containers and the sorting and disposal facilities. When waste is placed in the recycling container, the container lacks a distribution component that automatically guides it to the corresponding disposal channel based on waste type. Various types of waste are mixed at the input end, requiring manual transport to the separate sorting and disposal facilities for further processing. This structural deficiency results in a necessary transfer step between waste input and disposal. During this transfer, the waste remains mixed, making it impossible to perform corresponding disposal operations for different types of waste at the input end. Furthermore, it is impossible to complete the seamless operation of waste sorting, identification, channel allocation, and corresponding disposal within the same device, thus creating the technical problem of not being able to sort and dispose of waste on-site.
[0003] Existing technical solutions have the problem that household waste is mixed after being delivered and cannot be separated and processed on-site. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a household waste recycling and disposal classification system, which solves the technical problem that existing technologies cannot separate and process household waste on-site when it is in a mixed state after being delivered.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a household waste recycling and disposal classification system, comprising at least one recycling bin, a classification unit, a storage unit, a processing unit, a controller, and a communication module; The storage unit includes multiple disposal tanks and a sealing mechanism, wherein the sealing mechanism is located at the inlet and outlet of each disposal tank; The output end of the recycling bin is connected to the input end of the sorting unit; The output of the sorting unit is connected to the input of each of the disposal bins; Each of the aforementioned treatment containers is equipped with a treatment unit; The controller is communicatively connected to the classification unit, the processing unit, and the enclosure mechanism, respectively.

[0006] The recycling bins, sorting units, and storage units are connected in sequence, forming a transport path for objects from input to classified storage. The sorting unit, driven by the controller's control signal, transports the objects to the corresponding disposal bins, completing the path switching for categorized storage. A closing mechanism is located at the input and output ends of each disposal bin, controlling its opening and closing status and cooperating with the controller to achieve independent opening and closing of each disposal bin. A processing unit is located in each disposal bin, performing at least one of physical, chemical, or biological treatment operations on the objects inside the bin under the control signal of the controller.
[0007] The communication module connects to the controller, giving the classification and processing units server-side artificial intelligence and remote processing capabilities, thereby improving analysis accuracy and precision processing capabilities.
[0008] In some embodiments, an image acquisition unit is further included. The image acquisition unit is disposed between the output end of the recycling bin and the input end of the sorting unit.

When the object with conductive properties passes through the magnetic sensing unit, the magnetic sensing unit generates an impedance signal and transmits it to the controller. The controller generates a control signal based on the impedance signal to drive the sorting unit to transport the object to the corresponding disposal bin.
[0010] In some embodiments, the processing unit includes a physical treatment mechanism disposed inside the treatment tank and controlled by the controller. The physical treatment mechanism is at least one of a compressor, a pulverizer, or a dryer / dehydrator.
[0011] In some embodiments, the processing unit includes a chemical treatment mechanism disposed inside the treatment tank and controlled by the controller.

[0016] In some embodiments, an incentive recycling module is further included, which is communicatively connected to the controller and associated with the recycling bin. The incentive recycling module includes a physical discharge mechanism and / or a signal output mechanism.
[0017] Beneficial Effects: This invention provides a household waste recycling and disposal sorting system. It employs an integrated structure consisting of a sorting unit, multiple disposal bins, and corresponding processing units for each bin. This achieves integrated operations where waste is sequentially sorted and disposed of within the same device after being deposited, eliminating the necessary transfer step before sorting and disposal. The system utilizes an image acquisition unit connected to a controller, and the controller connected to the sorting unit. This enables automatic sorting based on waste appearance images, automatically generating control signals to drive the sorting unit to its corresponding output channel, replacing manual waste identification and bin placement.

[0020] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Detailed description follows.
[0021] Please see Figure 1 The present invention provides a technical solution: a household waste recycling and disposal classification system, comprising at least one recycling bin 1, a classification unit 2, a storage unit, a processing unit, a controller 5, and a communication module; The storage unit includes multiple disposal tanks 3 and a sealing mechanism 4, with the sealing mechanism 4 located at the inlet and outlet of each disposal tank 3; The output end of recycling bin 1 is connected to the input end of sorting unit 2; The output of sorting unit 2 is connected to the input of each disposal bin 3; Each disposal tank 3 is equipped with a disposal unit; The controller 5 is communicatively connected to the sorting unit 2, the processing unit, and the enclosing mechanism 4, respectively. The sorting unit 2 transports the objects output from the recycling bin 1 to the corresponding disposal bin 3 according to the control signal of the controller 5; The processing unit performs at least one of physical, chemical, or biological treatments on the objects in the treatment tank 3 based on the control signal from the controller 5. The communication module communicates with the controller and connects with the IoT big data unit of the external data processing platform via a multi-band network.
[0022] The recycling bin 1, sorting unit 2, and storage unit are connected sequentially to form a transport path for objects from input to sorted storage. Under the control signal of controller 5, sorting unit 2 transports objects to the corresponding disposal bin 3, completing the path switching for sorting and storage. A closing mechanism 4 is located at the input and output ends of disposal bin 3 to control the opening and closing state of disposal bin 3, cooperating with controller 5 to achieve independent opening and closing of each disposal bin 3. A processing unit is located in each disposal bin 3 and, under the control signal of controller 5, performs at least one of the following treatment operations on the objects inside the bin: physical treatment, chemical treatment, or biological treatment.
[0023] In some embodiments, an image acquisition unit is also included. The image acquisition unit is disposed between the output end of the recycling bin 1 and the input end of the sorting unit 2. The image acquisition unit is signal-connected to the controller 5. The image acquisition unit is used to acquire the appearance image information of the object output by the recycling bin 1 and transmit it to the controller 5. The controller 5 generates a control signal based on the appearance image information to drive the sorting unit 2 to transport the object to the corresponding disposal bin 3.
[0024] An image acquisition unit is positioned between the output of recycling bin 1 and the input of sorting unit 2. It acquires appearance image information of objects passing through this location and transmits the appearance image information to controller 5. Controller 5 generates corresponding control signals based on the appearance image information as input, driving sorting unit 2 to transport the objects to the corresponding disposal bin 3, thus completing the determination of the sorting path based on visual information.
[0025] In some embodiments, a magnetic sensing unit is also included. The magnetic sensing unit is disposed between the output end of the recycling bin 1 and the input end of the sorting unit 2. The magnetic sensing unit is signal-connected to the controller 5. The magnetic sensing unit is an induction coil carrying alternating current. When an object with conductor properties passes through the magnetic sensing unit, the magnetic sensing unit generates an impedance signal and transmits it to the controller 5. The controller 5 generates a control signal based on the impedance signal to drive the sorting unit 2 to transport the object to the corresponding disposal bin 3.
[0026] The magnetic sensing unit uses an induction coil carrying alternating current as a carrier. It generates an impedance response to objects with conductive properties passing through the unit, producing an impedance signal that is transmitted to the controller 5. The controller 5 uses the impedance signal as input to generate a corresponding control signal, driving the classification unit 2 to transport the object to the corresponding disposal bin 3, thus completing the classification path determination based on conductive properties. The magnetic sensing unit is arranged side-by-side with the image acquisition unit, providing the system with another method for acquiring object features.
[0027] In some embodiments, the processing unit includes a physical treatment mechanism disposed in the treatment tank 3 and controlled by the controller 5. The physical treatment mechanism is at least one of a compressor, a pulverizer, or a dryer / dehydrator.
[0028] A physical treatment mechanism is installed inside the treatment tank 3, and applies mechanical or thermal action to the objects inside the tank through at least one of a compressor, a pulverizer, or a dryer. The physical treatment mechanism is connected to a controller 5, which selects the corresponding physical treatment operation based on the type of object inside the treatment tank 3.
[0029] In some embodiments, the processing unit includes a chemical treatment mechanism disposed inside the treatment tank 3. The chemical treatment mechanism is controlled and connected to the controller 5. The chemical treatment mechanism includes a liquid storage container and a filling pipeline. The liquid storage container is connected to the inner cavity of the treatment tank 3 through the filling pipeline. An electrically controlled valve controlled by the controller 5 is provided on the filling pipeline.
[0030] The chemical treatment unit stores chemical reagents in a storage container, which is connected to the inner cavity of the treatment tank 3 via a filling pipeline, forming a delivery path for the chemical reagents. An electrically controlled valve installed on the filling pipeline is controlled by a controller 5, which controls the injection of chemical reagents into the inner cavity of the treatment tank 3 by opening and closing the electrically controlled valve.
[0031] In some embodiments, the processing unit includes a biological treatment mechanism disposed within the treatment tank 3 and controlled by a controller 5. The biological treatment mechanism includes a microbial agent dosing device and / or an environmental control device, which includes at least one of a temperature regulator, a humidity regulator, and a ventilation device.
[0032] The biological treatment unit adds microbial agents to the treatment tank 3 using a microbial agent dosing device, and regulates the temperature, humidity, or oxygen content parameters inside the treatment tank 3 using an environmental control device. Both can operate independently or in combination. The temperature regulator, humidity regulator, and ventilation device in the environmental control device independently regulate the corresponding environmental parameters inside the treatment tank 3. Each device is connected and controlled by a controller 5, which selects and activates the corresponding device according to the treatment requirements.
[0033] In some embodiments, the system further includes an exhaust gas treatment unit, which is connected to the exhaust end of the disposal tank 3 via a pipeline. The exhaust gas treatment unit is controlled by a controller 5. The exhaust gas treatment unit includes a filtration and purification mechanism and / or a deodorization mechanism. An exhaust valve controlled by the controller 5 is provided on the pipeline.
[0034] It also includes an exhaust gas treatment unit, which is connected to the exhaust end of the disposal tank 3 via a pipeline. The exhaust gas treatment unit is controlled by the controller 5. The exhaust gas treatment unit includes a filtration and purification mechanism and / or a deodorization mechanism. An exhaust valve controlled by the controller 5 is installed on the pipeline.
[0035] In some embodiments, the system further includes a wastewater treatment unit, which is connected to the drain end of the treatment tank 3 via a pipeline. The wastewater treatment unit is controlled by a controller 5. The wastewater treatment unit includes a solid-liquid separation mechanism and / or a purification mechanism. A drain valve controlled by the controller 5 is provided on the pipeline.
[0036] The wastewater treatment unit is connected to the drain end of the treatment tank 3 via a pipeline, forming a discharge path for the liquid inside the treatment tank 3. The drain valve installed on the pipeline is controlled by the controller 5, which controls the timing of liquid introduction into the wastewater treatment unit by opening and closing the drain valve. The solid-liquid separation mechanism and purification mechanism in the wastewater treatment unit can be set up separately or in combination, respectively performing solid-liquid separation operations and subsequent purification operations on the introduced liquid.
[0037] In some embodiments, the multi-band network includes at least one communication band, which includes at least one of cellular mobile communication band, low-power wide area network band, and local wireless communication band. The communication module 6 detects the signal strength of each communication band in real time and selects the communication band to maintain communication with the external data processing platform based on the signal strength.
[0038] The cellular mobile communication band possesses high bandwidth and wide coverage communication capabilities, used to carry out real-time data upload tasks and bidirectional transmission of remote control commands between the communication module 6 and the external data processing platform, ensuring the real-time performance and integrity of waste disposal status data and disposal parameter adjustment commands. The low-power wide-area network (LPWAN) band possesses low power consumption and long-distance transmission characteristics, used to maintain continuous transmission of status monitoring data between the communication module 6 and the external data processing platform in scenarios where cellular mobile communication band signal strength is insufficient or network congestion occurs, ensuring the continuity of the system communication link. The local wireless communication band possesses near-field high-speed response communication capabilities, used for local device collaborative communication between the communication module 6 and recycling bin 1, controller 5, and various disposal units, realizing low-latency issuance of multi-device linkage control commands and real-time feedback of execution status. The communication module 6 continuously monitors the real-time signal strength of the above communication bands and automatically switches between communication bands according to a preset signal strength priority strategy to ensure that the system can maintain a stable communication connection with the external data processing platform in different network environments.
[0039] In some embodiments, an incentive recovery module is also included, which is communicatively connected to the controller 5 and associated with the recovery bin 1. The incentive recovery module includes a physical discharge mechanism and / or a signal output mechanism.
[0040] The incentive recycling module is communicatively connected to the controller 5. The controller 5 sends a trigger signal to the incentive recycling module after detecting an object being placed into the recycling bin 1. The incentive recycling module is associated with the recycling bin 1 and, based on the trigger signal from the controller 5, outputs a physical reward via a physical dispensing mechanism or a signal via a signal output mechanism, such as a non-physical resource reward like a QR code. These two settings can be configured individually or in combination, and the controller 5 selects and activates the corresponding mechanism according to the actual configuration.
[0041] like Figure 1 As shown, Example 1: Chemically treated type Classification unit 2 uses an electric paddle-type distributor, driven by a stepper motor. The sealing mechanism 4 uses an electric flap valve. The image acquisition unit uses an industrial camera. The processing unit primarily uses a chemical treatment mechanism, with electromagnetically controlled valves. Both the exhaust valve and the drain valve are electromagnetic valves. Communication module 6 uses a multi-band network communication module. The physical material discharge mechanism is spring-push type, and the signal output mechanism uses a multimedia electronic screen.
[0042] After the recyclable material is put into the recycling bin 1, it enters the acquisition position of the industrial camera through the conveying channel. The industrial camera acquires the appearance image information of the recyclable material and transmits it to the controller 5. The controller 5 identifies the category of the recyclable material based on the appearance image information, generates a control signal to drive the stepper motor to rotate, and the stepper motor drives the lever to switch to the corresponding output channel position. The recyclable material falls into the input end of the corresponding disposal bin 3 through this channel. The electric flap valve opens, and the electric flap valve closes after the recyclable material enters the disposal bin 3.
[0043] Controller 5 selects the appropriate treatment agent based on the type of recyclable material, driving the electromagnetic control valve to open. The chemical treatment unit then injects a measured amount of treatment agent into the treatment tank 3 through the injection pipeline. For organic recyclables, an oxidizing decomposition agent is injected to degrade the organic matter into smaller molecules; for metallic recyclables, a passivating and protective agent is injected to prevent metal oxidation and corrosion; for hazardous recyclables, a neutralizing and solidifying agent is injected to chemically solidify the hazardous components, reducing their harmfulness. After the agent injection is completed, the electromagnetic control valve closes. The waste gas generated during the chemical reaction is discharged into the waste gas treatment unit through the exhaust valve, where it passes through a filtration and purification unit to filter out harmful particles and an odor removal unit to adsorb odorous gases before being discharged in compliance with standards. The waste liquid generated is discharged into the wastewater treatment unit through the drain valve, where it passes through a solid-liquid separation unit to separate solid residues and a purification unit to purify the liquid before being discharged in compliance with standards.
[0044] For chemical waste treatment: Kitchen waste: The main components of kitchen waste are organic macromolecules such as protein, fat, and starch. An alkaline hydrolysis agent is injected into treatment tank 3. Under alkaline conditions, proteins undergo hydrolysis, peptide bonds break, and proteins decompose into small amino acid molecules. Fat undergoes saponification under alkaline conditions, glycerides hydrolyze into glycerol and fatty acid salts, the fat clumps disintegrate, and organic matter changes from a solid to a soluble liquid, significantly reducing its volume. This facilitates subsequent discharge into the wastewater treatment unit for purification via a drain valve. A small amount of volatile gases such as ammonia is generated during the reaction, which are discharged into the waste gas treatment unit via an exhaust valve. After treatment by the filtration and deodorization mechanisms, the gas is discharged in compliance with standards.
[0045] Hazardous waste includes: used batteries containing heavy metal ions, broken fluorescent tubes releasing mercury vapor, and expired medicines containing residual active ingredients. A heavy metal chelating and solidifying agent is injected into disposal container 3. The chelating agent coordinates with the heavy metal ions to form stable metal chelates, solidifying the heavy metal ions in solid chelate form and eliminating their ability to migrate in a liquid environment, thus reducing the risk of leakage into the external environment. The active ingredients in expired medicines are treated with an oxidizing and decomposing agent, where the organic active ingredients are oxidized and decomposed into inactive small molecules. The solidified residue is retained in disposal container 3 for subsequent centralized collection and transportation for specialized disposal.
[0046] Recyclable waste: Waste metal surfaces are prone to oxidation and corrosion under the combined action of air and moisture, leading to a decline in metal quality and affecting recycling value. Injecting a metal passivation agent into treatment container 3 causes phosphoric acid to neutralize the oxides on the metal surface, transforming the loose oxide layer into a dense phosphate protective film. This blocks contact between the metal surface and external oxygen and moisture, inhibiting further oxidation. Organic pollutants adhering to the surfaces of waste paper and waste plastics are wetted and dispersed by a surfactant solution. The pollutants detach from the surfaces of waste paper and waste plastics and dissolve in the liquid phase, cleaning the surfaces and improving the purity of the recyclables, facilitating subsequent recycling.
[0047] Other types of waste: Other types of waste are relatively stable in chemical properties. The main problems are dust emission and the adhesion of mixed pollutants. A dust-fixing and wetting agent is injected into the treatment tank 3. The polymer flocculant adsorbs and bridges the fine dust particles in the waste, causing the dust particles to flocculate and agglomerate into larger particles, which settle at the bottom of the treatment tank 3, thus inhibiting the emission of dust inside the treatment tank 3 and in the exhaust channel. Organic pollutants adhering to the surface of composite material waste are dissolved and separated by organic solvents. The pollutants migrate to the liquid phase with the solvent phase and are discharged into the wastewater treatment unit for purification through the drain valve.
[0048] Example 2: Physical Processing Type The difference between this embodiment and Embodiment 1 is that the processing unit uses a physical treatment mechanism instead of a chemical treatment mechanism as the main treatment method, while the selection of other components is the same as in Embodiment 1.
[0049] The physical treatment mechanism uses a hydraulic compressor. After the recyclables are put into the recycling bin 1, they enter the acquisition position of the industrial camera through the conveying channel. The industrial camera acquires the appearance image information of the recyclables and transmits it to the controller 5. The controller 5 identifies the type of recyclables based on the appearance image information, generates a control signal to drive the stepper motor to rotate, and the stepper motor drives the lever to switch to the corresponding output channel position. The recyclables fall into the input end of the corresponding treatment bin 3 through this channel. The electric flap valve opens, and the electric flap valve closes after the recyclables enter the treatment bin 3.
[0050] Controller 5 drives the hydraulic compressor to start, applying compression force to the recyclables in the treatment tank 3 to reduce their volume. For recyclable materials, the hydraulic compressor compresses and packages them, significantly reducing their volume for easier centralized transportation. For kitchen waste, the hydraulic compressor crushes and breaks down the organic cellular structure, accelerating the subsequent natural degradation process. For other types of recyclables, the hydraulic compressor compresses and reduces their volume, minimizing space requirements. Waste gas generated during the compression process is discharged into the waste gas treatment unit via an exhaust valve and treated to meet emission standards. Waste liquid squeezed out by compression is discharged into the wastewater treatment unit via a drain valve and treated to meet emission standards.
[0051] Example 3: Biological Treatment Type The difference between this embodiment and Embodiment 1 is that the processing unit uses a combination of physical and biological treatment mechanisms to replace the chemical treatment mechanism as the main treatment method, while the selection of other components is the same as in Embodiment 1.
[0052] The physical treatment mechanism uses a pulverizer, the microbial agent dosing device uses a peristaltic pump, the temperature regulator uses a resistance heating mechanism, the humidity regulator uses an ultrasonic atomizing type, and the ventilation device uses an electric air valve type.
[0053] After the recyclable material is put into the recycling bin 1, it enters the acquisition position of the industrial camera through the conveying channel. The industrial camera acquires the appearance image information of the recyclable material and transmits it to the controller 5. The controller 5 identifies the category of the recyclable material based on the appearance image information, generates a control signal to drive the stepper motor to rotate, and the stepper motor drives the lever to switch to the corresponding output channel position. The recyclable material falls into the input end of the corresponding disposal bin 3 through this channel. The electric flap valve opens, and the electric flap valve closes after the recyclable material enters the disposal bin 3.
[0054] First, controller 5 drives the pulverizer to crush the recyclables in treatment tank 3, making the recyclables loose and increasing their specific surface area, creating favorable conditions for subsequent biological treatment. After the pulverization process is completed, controller 5 drives the peristaltic pump to add functional microbial agents corresponding to the type of recyclables into treatment tank 3: for kitchen waste, organic matter degrading bacteria are added to decompose food residues, grease, and other organic matter into humic substances and small-molecule organic acids; for green waste, cellulose degrading bacteria are added to decompose plant cellulose, lignin, and other high-molecular-weight organic matter into soluble sugars and humic substances. After the microbial agents are added, the temperature regulator adjusts the temperature in treatment tank 3 to a suitable range for microbial activity, the humidity regulator adjusts the humidity in treatment tank 3 to maintain the activity of the microbial agents, and the ventilation device periodically introduces air into treatment tank 3 to provide oxygen for aerobic microorganisms. The three work together to provide a continuous and stable environmental condition for the biological treatment process. The waste gas generated during the biological treatment process is discharged into the waste gas treatment unit through the exhaust valve, and then passes through the filtration and purification mechanism and the deodorization mechanism in sequence before being discharged in compliance with standards; the waste liquid generated is discharged into the wastewater treatment unit through the drain valve, and then passes through the solid-liquid separation mechanism and the purification mechanism in sequence before being discharged in compliance with standards.
[0055] Classification unit 2 automatically identifies and classifies the household waste into five categories: kitchen waste, recyclable waste, hazardous waste, green waste, and other waste. Each category is then directed to its corresponding disposal bin 3. Kitchen waste includes leftover food, vegetable and fruit peels, bones, fish bones, cooking oil waste, and expired food—organic wet waste generated daily in households. Recyclable waste includes waste paper, cardboard boxes, paper packaging, waste plastic bottles, waste metal products, glass bottles and jars, and waste textiles—waste with recycling value. Hazardous waste includes waste dry cell batteries, waste rechargeable batteries, waste fluorescent tubes, waste thermometers, expired medicines, and waste pesticide containers—waste containing substances harmful to humans or the environment. Green waste includes tree branches, leaves, lawn mowing waste, fallen leaves, and discarded plant material from garden pruning. Other waste includes ceramic fragments, brick and lime waste, composite material waste, and mixed waste that is difficult to categorize into the above four categories. The sorting unit 2 uses an image recognition sensor to identify the appearance of the waste and a weight sensor to detect the quality of the waste. The identification results are transmitted to the controller 5, which then controls the sorting guide mechanism to guide the waste into the corresponding disposal bin 3, thus achieving automatic and accurate waste sorting.
[0056] Biological treatment method: Kitchen waste: Add a compound organic matter degrading agent to treatment bin 3. The agent mainly consists of a complex microbial community of Bacillus, lactic acid bacteria, and yeast. Bacillus secretes extracellular proteases to hydrolyze proteins in food residues into polypeptides and amino acids; yeast secretes amylase and saccharifying enzymes to hydrolyze starchy organic matter into soluble sugars such as glucose; lactic acid bacteria use glucose as a substrate for homolactic fermentation, converting soluble sugars into lactic acid, lowering the pH value in treatment bin 3, inhibiting the growth of putrefactive bacteria, and simultaneously acidifying the surface of fat globules with the lactic acid bacteria, causing the fat globules to emulsify and disperse, accelerating the hydrolysis of fats by lipase. A temperature regulator maintains the temperature in treatment bin 3 within a suitable range for bacterial activity, a humidity regulator maintains a suitable moisture content, and a ventilation device intermittently introduces air to provide oxygen for aerobic bacteria. These three elements work together to provide environmental support for the continuous and stable metabolic activities of the microbial community. Ultimately, kitchen waste is degraded into humus, small-molecule organic acids, carbon dioxide, and water, with a significant reduction in volume. The humus can be used as a raw material for organic fertilizer.
[0057] Green waste: The main components of green waste are cellulose, hemicellulose, and lignin, which are high-molecular-weight organic polymers with an extremely long degradation cycle under natural conditions. Cellulose-degrading microbial agents are added to treatment container 3. These agents mainly consist of a complex microbial community of Trichoderma, white-rot fungi, and Cellulobacillus. Trichoderma secretes cellulase, and the three enzymes work synergistically to gradually hydrolyze long cellulose chains into cellobiose, which is then further hydrolyzed into glucose. White-rot fungi secrete lignin peroxidase and manganese peroxidase, which break the aromatic ring structure of lignin through redox reactions, decomposing large lignin molecules into small phenolic compounds. Hemicellulose is hydrolyzed by hemicellulase into pentoses such as xylose and arabinose. These degradation products are further utilized by the microbial community for metabolism, ultimately transforming into humus, which can be used as a soil amendment. The physical treatment facility pre-compacts and crushes the green waste, breaking down the plant fiber cell structure and exposing cellulose and hemicellulose outside the cells. This reduces the mass transfer resistance between the microbial degradation enzymes and the substrate, improving the efficiency of the biodegradation process.
[0058] Paper recyclable waste: Ink, adhesives, and organic pollutants adhere to the surface of waste paper, affecting the quality of recycling and reuse. Add ink-degrading bacteria to disposal bin 3 to degrade and remove pollutants.
[0059] The chemical storage unit should use a sealed container made of corrosion-resistant material. The container's outer wall should have a double-layer protective structure; the inner layer is in direct contact with the chemical, while the outer layer serves as a leak protection layer. A liquid level sensor should be installed between the two layers. When the inner container leaks, the sensor should send an alarm signal to the controller 5. A double shut-off valve series structure should be used between the chemical filling pipeline and the inlet of the treatment tank 3. Both shut-off valves should be closed when not filling to prevent leakage of the chemical into the treatment tank 3 or the external environment. A leak-proof tray should be installed at the bottom of the chemical storage area. The tray's volume should be no less than the maximum single filling volume to prevent accidental leakage of the chemical from spreading to the ground outside the unit. Alkaline chemicals, oxidizing chemicals, and chelating agents should be stored separately in designated areas, with isolation baffles between each storage area to prevent accidental reactions between different types of chemicals due to container breakage.
[0060] The biological agent storage unit should use a sealed, low-temperature storage container. Temperature and humidity sensors are installed inside the container, and a temperature regulator maintains the internal temperature within the specified storage range for the agent, preventing excessively high temperatures from causing uncontrolled agent activity or excessively low temperatures from causing agent inactivation. A one-way valve is installed at the end of the agent dosing pipeline to prevent gas and liquid in the treatment tank 3 from flowing back into the agent storage container, thus avoiding contamination of the agent storage container by other microorganisms in the treatment tank 3. An isolation and sealing structure is installed between the outer wall of the agent storage container and the external environment. The container opening is connected to the outside air through a high-efficiency filter to prevent active microorganisms in the agent from escaping into the external environment with the airflow. A level sensor is installed in the storage container. When the remaining agent level falls below a set threshold, the controller 5 sends a replenishment reminder to the management terminal via the communication module 6 to prevent interruptions in the treatment process due to insufficient agent levels.
[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way.
