Description

Technical Field

[0001] This application relates to the field of leachate treatment technology, and in particular to a modular system for the full-scale treatment of multi-concentration leachate. Background Technology

[0002] Multi-concentration leachate typically refers to a liquid used in laboratory or industrial production where the solution contains varying concentrations of solute. This liquid is often obtained by dissolving different amounts of solute (usually a solid or liquid substance) in a solvent.

[0003] In industrial production, the typical processing capacity of multi-concentration leachate can reach 150 days per ton (t), and its use is common. For example, in industries such as pharmaceuticals, chemicals, and food processing, it may be necessary to treat solutions of different concentrations to produce the final product. Percolation is a common separation technique used to separate solid particles or other solutes from a liquid.

[0004] In the process of treating leachate of different concentrations, it is usually necessary to use a specially designed treatment system. Generally, one treatment system is used for different concentrations of leachate, which has a narrow range of applications. Summary of the Invention

[0005] To adapt to leachate of various concentrations and achieve intelligent control and full quantification, this application provides a modular treatment system for leachate of various concentrations.

[0006] The multi-concentration leachate full-scale modular treatment system provided in this application adopts the following technical solution:

[0007] A multi-concentration leachate fully modular treatment system, including:

[0008] The pretreatment tank is provided in a plurality of interconnected pretreatment tanks, and each pretreatment tank is equipped with a water pump for transferring leachate of multiple concentrations between the plurality of pretreatment tanks.

[0009] A flow meter, which is connected to the pretreatment tank at the end;

[0010] A membrane reduction device, which is connected to the flow meter, and which has a built-in material separation membrane and a desalination membrane;

[0011] An integrated evaporation and drying machine is connected to the output end of the membrane reduction device, and is used for evaporating and drying leachate of multiple concentrations;

[0012] The detection device is used for water quality and odor monitoring. The detection device includes a multi-functional detection sensor and a controller. The multi-functional detection sensor is installed on the pretreatment tank, the membrane reduction device, and the integrated steam drying machine. The multi-functional detection sensor is electrically connected to the controller.

[0013] By adopting the above technical solution, firstly, the pretreatment tanks enable the system to accommodate and treat leachate of multiple concentrations. Each pretreatment tank is equipped with a water pump to transfer leachate of different concentrations between different pretreatment tanks, ensuring the system can flexibly adapt to liquids of various concentrations. Flow meters are connected to the end pretreatment tanks to accurately monitor the liquid flow rate in the system. This helps control the flow rate of the liquid in the system and ensures the coordinated operation of each treatment unit. The membrane dewatering unit incorporates material separation membranes and desalination membranes, effectively separating solutes and solids in leachate of different concentrations. This helps reduce membrane fouling, extend membrane life, and thus improve the stability and efficiency of the system. The evaporation-drying unit is connected to the output of the membrane dewatering unit for evaporating and drying leachate of multiple concentrations. This step helps evaporate water from the liquid, making solids easier to handle or recover. The detection device includes multifunctional detection sensors and controllers, distributed on the pretreatment tanks, membrane dewatering unit, and evaporation-drying unit, for real-time monitoring of water quality and odor. This enables the system to possess intelligent control capabilities, allowing it to adjust the operating parameters of each processing unit in real time based on monitoring results, ensuring efficient operation under various conditions. Overall, this technical solution, through modular design and intelligent control, achieves comprehensive treatment of leachate of various concentrations, improving the system's adaptability and operational efficiency.

[0014] Preferably, the integrated steam drying machine includes a housing, an MVR evaporator processing chamber, and a conveyor belt. The MVR evaporator processing chamber and the conveyor belt are built into the housing. The input end of the MVR evaporator processing chamber is connected to the output end of the membrane reduction device. The output end of the MVR evaporator processing chamber is located above the conveyor belt. A power component is provided on the conveyor belt to drive the conveyor belt. A first collection component is provided on the side wall of the housing, and the end of the conveyor belt is connected to the first collection component.

[0015] By adopting the above technical solution, during operation, multi-concentration leachate enters the MVR evaporator treatment chamber from the output end of the membrane reduction device. The MVR evaporator treatment chamber evaporates the leachate to remove moisture. The treated material is discharged from the output end of the MVR evaporator treatment chamber and is located above the conveyor belt. A power component is installed on the conveyor belt, which drives the conveyor belt to smoothly transport the treated solute concentrate. A first collection component is installed on the side wall of the chamber, and the end of the conveyor belt is connected to the first collection component to ensure smooth collection of the treated material. Throughout the process, the integrated design of the MVR evaporator treatment chamber and the conveyor belt improves the processing efficiency, while the first collection component helps to conveniently and reliably collect the treated solute concentrate, thus achieving the effects of efficient evaporation and drying and convenient collection of solute concentrate. At the same time, unlike the traditional process of burning biomass to generate heat, this application can utilize the waste heat generated by evaporation in the MVR evaporator treatment chamber to dry the solute concentrate, further removing moisture and achieving energy-saving effects.

[0016] Preferably, the conveyor belt includes a support plate, a drive roller, a driven roller, and a conveyor belt. Two support plates are provided. The drive roller and the driven roller are rotatably supported between the two support plates. The conveyor belt is sleeved on the drive roller and the driven roller. The power component is a drive motor, which is mounted on one of the support plates. The drive motor drives the drive roller to rotate.

[0017] By adopting the above technical solution, during operation, after the drive motor starts, it transmits power to the drive roller, causing it to rotate. This motion is transmitted to the driven roller via the conveyor belt, initiating the operation of the entire conveyor belt. The supporting role of the bearing plate ensures stable rotation between the drive and driven rollers, while the conveyor belt smoothly transports the solute concentrate. This design realizes the conveyor belt's operating mechanism: the drive motor, through the rotation of the drive roller, drives the conveyor belt and driven rollers, thereby transporting the solute concentrate along the conveyor belt direction. This conveyor belt structure design is simple, operates smoothly and reliably, and effectively completes the task of transporting the solute concentrate.

[0018] Preferably, the surface of the conveyor belt is provided with a plurality of ventilation holes.

[0019] By adopting the above technical solution, during the drying process, the vents allow hot air to effectively penetrate into the solute concentrate, promoting faster evaporation of the solute. This design accelerates the transfer of moisture from the solute concentrate to the air, achieving a faster and more efficient drying process.

[0020] Preferably, a rotating rod is rotatably supported between the two support plates. The rotating rod is coaxially arranged with the output shaft of the drive motor, and a separation rod is circumferentially arranged on the outer wall of the rotating rod.

[0021] By adopting the above technical solution, during operation, when the drive motor starts, the output shaft of the drive motor transmits power to the coaxially mounted rotating rod. Since the outer wall of the rotating rod is circumferentially equipped with a separating rod, as the rotating rod rotates, the separating rod passes through the adhered solute concentrate. This process is similar to a mechanical dispersing operation, helping to separate the adhered materials, making them easier to dry and process.

[0022] Preferably, a screw and a guide rod are provided between the two bearing plates. The screw is rotatable. A first transmission component is provided between the screw and the drive motor. A brush is threaded onto the screw. The brush is movably sleeved on the guide rod. The brush is used to disperse the solute concentrate.

[0023] By adopting the above technical solution, during operation, the drive motor starts, and the screw begins to rotate through the action of the first transmission component. This causes the brush to move along the guide rod, and its movable sleeve allows for effective dispersion of the solute concentrate. The effect of this process is that, through the rotation of the screw and the movement of the brush, effective dispersion of the solute concentrate is achieved, thus realizing effective treatment of the solute concentrate.

[0024] Preferably, the first transmission component is configured as two transmission gears, one of which is coaxially arranged with the output shaft of the drive motor, and the other of which is coaxially arranged with the screw.

[0025] By adopting the above technical solution and using the coaxial arrangement of the transmission gears, effective energy transfer and mechanical connection are achieved, enabling the rotational motion of the drive motor to be transmitted to the screw. This coaxial transmission design improves the stability and efficiency of the system, ensuring that the power of the drive motor can be effectively converted into the rotational motion of the screw, thereby driving the entire process of dispersing and concentrating the solute.

[0026] Preferably, the first collecting component includes an inclined plate and a first material box. The inclined plate is installed inside the box body. A first opening is provided on the side wall of the box body. One end of the inclined plate is connected to the conveyor belt, and the other end of the inclined plate extends out of the first opening. The first material box is fixed to the outer side wall of the box body, and the other end of the inclined plate is located above the first material box.

[0027] By adopting the above technical solution, an inclined plate is installed inside the housing and connected to the conveyor belt through a first opening in the side wall of the housing. The solute concentrate on the conveyor belt is guided to the inclined plate, then moves along the inclined plate, and finally extends out from the first opening of the housing, effectively collecting the solute concentrate from the conveyor belt and transferring it to the hopper, providing an efficient and controllable solution for the safe storage of the concentrate.

[0028] Preferably, the box body is further provided with a second collection component, the second collection component includes a feeding plate and a second material box, one end of the feeding plate is rotatably supported in the box body, a second transmission component is provided between the feeding plate and the conveyor belt, a second opening is provided on the side wall of the box body, and the other end of the feeding plate extends out of the second opening and is located above the second material box.

[0029] By adopting the above technical solution, in addition to the first collection component, a second collection component is also provided for more comprehensive collection of solute concentrate. The second collection component includes a feeding plate and a second material box. One end of the feeding plate is rotatably supported in the box, and a second transmission component is provided between it and the conveyor belt. A second opening is provided on the side wall of the box, allowing the other end of the feeding plate to extend out and be positioned above the second material box.

[0030] During operation, some of the solute concentrate that falls through the vent holes lands on the feed plate. A second transmission component causes the feed plate to rotate, guiding the solute concentrate to the second outlet. As the feed plate moves, the solute concentrate flows out of the second outlet and is safely stored in the second tank. This design, by introducing a second collection assembly, gives the system greater processing capacity and collection capacity, improving the efficient processing and centralized storage of solute concentrate.

[0031] Preferably, the second transmission component is configured as a crank-connecting rod mechanism, wherein the turntable of the crank-connecting rod mechanism is coaxially arranged with the driven roller, and the connecting rod of the crank-connecting rod mechanism is hinged to the feed plate.

[0032] By adopting the above technical solution, during the transmission process, the driving force is transmitted to the turntable of the crank-connecting rod mechanism through the driven roller. Since the turntable of the crank-connecting rod mechanism is coaxial with the driven roller, the turntable rotates along with the driven roller. The connecting rod of the crank-connecting rod mechanism is hinged to the feed plate, thus converting the rotational motion into the linear motion of the feed plate. When the turntable of the crank-connecting rod mechanism rotates, the hinge of the connecting rod causes the feed plate to begin oscillating, guiding the solute concentrate to fall into the second feed box.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. Through modular design and intelligent control, the system achieves full-scale treatment of leachate of various concentrations, improving the system's adaptability and operational efficiency;

[0035] 2. It can utilize the waste heat generated by evaporation in the MVR evaporator to dry the solute concentrate, further removing moisture and achieving energy-saving effects; Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0040] This application discloses a modular system for the full-scale treatment of multi-concentration leachate. (Refer to...) Figure 1 and Figure 2 The multi-concentration leachate full-scale modular treatment system includes a pretreatment tank 1, a flow meter 2, a membrane reduction device 3, an integrated evaporation and drying machine 4, and a detection device (not shown in the figure). The pretreatment tank 1 is used to pretreat multi-concentration leachates, the flow meter 2 is used to detect the flow rate, the membrane reduction device 3 is used for filtration, the integrated evaporation and drying machine 4 is used to evaporate and dry multi-concentration leachates, and the detection device is used for water quality and odor monitoring.

[0041] Specifically, there are several pretreatment tanks 1, and in this embodiment there are two. The two pretreatment tanks 1 are arranged at intervals in the horizontal direction and are connected. Each pretreatment tank 1 is equipped with a water pump, which is used to transfer leachate of multiple concentrations between the several pretreatment tanks 1.

[0042] In this embodiment, physical methods such as air flotation and flocculation sedimentation are introduced. By injecting flocculants, flocculant aids and gas into the pretreatment tank 1, air bubbles and flocs are formed, which helps to quickly fix and separate suspended solids and oils.

[0043] Simultaneously, chemical methods can be introduced, such as adding oil removers, flocculants, and hardness enhancers. Oil removers help disperse and separate grease, while flocculants can aggregate suspended solids into larger particles, facilitating subsequent sedimentation and separation. Hardness enhancers can be used to increase the hardness of water and stabilize water quality.

[0044] Furthermore, flow meter 2 is connected to the pretreatment tank 1 at the end, enabling accurate monitoring of the liquid flow rate in the system. This helps control the liquid flow rate within the system and ensures coordinated operation of each processing unit.

[0045] Furthermore, the membrane reduction device 3 is connected to the flow meter 2. The membrane reduction device 3 contains a material separation membrane and a desalination membrane. Correspondingly, the main function of the material separation membrane is to separate and remove specific substances, such as impurities, ions, or macromolecules, from the filtrate through selective permeability. This can be achieved through the microporous structure or selective permeability of the membrane, allowing only molecules of a specific size or property to pass through the membrane, while other substances are blocked.

[0046] Meanwhile, the function of a desalination membrane is to achieve desalination or concentration of a solution. This is achieved by utilizing the permeability of a semi-permeable membrane, allowing the solvent to pass through the membrane while preventing the transfer of solute. In this way, the system can control the concentration of substances in the solution, concentrating the substances in the solution to a certain degree, or diluting them through a reverse process.

[0047] In summary, material separation membranes and desalination membranes play crucial roles in multi-concentration filtrate treatment systems. Material separation membranes are responsible for separating and purifying the filtrate, while desalination membranes concentrate or dilute the solution, enabling the system to effectively treat liquids of varying concentrations and meet specific treatment requirements. The design of this membrane reduction device 3 improves the system's accuracy and flexibility, making it suitable for various liquid treatment scenarios.

[0048] Furthermore, multifunctional sensors are installed on the pretreatment tank 1, the membrane reduction device 3, and the integrated evaporation and drying unit 4. These sensors detect and measure various parameters in the liquid and air, including dissolved oxygen, pH value, turbidity, COD, ammonia nitrogen, and other water quality indicators, as well as odor components. These multifunctional sensors communicate with the intelligent controller in real time via electrical connection, establishing a comprehensive monitoring and control system.

[0049] During operation, the multi-functional detection sensor first collects data from the environment, and then transmits this data to the controller via electrical connection. The controller is responsible for processing and analyzing the received data, comparing it with preset standards or thresholds, and generating corresponding water quality and odor monitoring reports. Based on the data analysis results, the controller can formulate corresponding control strategies, such as adjusting the operating parameters of the membrane reduction device 3 and triggering the alarm system.

[0050] Therefore, this collaborative system effectively achieves real-time monitoring and precise control of water quality and odor. Through comprehensive monitoring by multi-functional sensors, the system can quickly respond to changes under different environmental conditions, improve system stability, ensure water quality meets standards, and effectively prevent potential environmental problems, providing a highly intelligent and reliable solution for multi-concentration filtrate treatment processes.

[0051] In addition, the steam drying machine 4 is connected to the output end of the membrane reduction device 3, and the output end of the steam drying machine 4 sends out the solute concentrate produced after processing.

[0052] In summary, the pretreatment tank 1 enables the system to accommodate and treat leachate of multiple concentrations. Each pretreatment tank 1 is equipped with a water pump to transfer leachate of different concentrations between different pretreatment tanks 1, ensuring the system can flexibly adapt to liquids of various concentrations. Flow meter 2 is connected to the end pretreatment tank 1 to accurately monitor the liquid flow rate in the system. This helps control the flow rate of the liquid in the system and ensures the coordinated operation of each treatment unit. Membrane dewatering unit 3 incorporates a material separation membrane and a desalination membrane, which can effectively separate solutes and solids in leachate of different concentrations. This helps reduce membrane fouling, extend membrane life, and thus improve the stability and efficiency of the system. Evaporator-dryer 4 is connected to the output of membrane dewatering unit 3 for evaporating and drying leachate of multiple concentrations. This step helps evaporate water from the liquid, making solids easier to process or recycle. The detection device includes multi-functional detection sensors and controllers, distributed on pretreatment tank 1, membrane dewatering unit 3, and evaporator-dryer 4, for real-time monitoring of water quality and odor. This enables the system to possess intelligent control capabilities, allowing it to adjust the operating parameters of each processing unit in real time based on monitoring results, ensuring efficient operation under various conditions. Overall, this technical solution, through modular design and intelligent control, achieves comprehensive treatment of leachate of various concentrations, improving the system's adaptability and operational efficiency.

[0053] On the other hand, the steam drying integrated machine 4 includes a housing 41, an MVR evaporator processing box 42, and a conveyor belt 43. The housing 41 is a hollow rectangular box. The top of the housing 41 is connected to the ventilation system of the production workshop to discharge water vapor. The MVR evaporator processing box 42 and the conveyor belt 43 are built into the housing 41. The input end of the MVR evaporator processing box 42 is connected to the output end of the membrane reduction device 3. The output end of the MVR evaporator processing box 42 is equipped with a discharge hopper, which is located above the conveyor belt 43.

[0054] In this embodiment, the MVR evaporator processing tank 42 refers to an evaporator using Mechanical Vapor Recompression (MVR) technology, which is typically used for liquid concentration in industrial processes. MVR technology compresses and heats low-temperature, low-pressure steam, then re-injects it into the evaporator to provide the required heat, thereby achieving an energy cycle in the evaporation process.

[0055] The processing chamber typically refers to the main structure of an evaporator, including components such as the evaporation chamber, heating elements, and recompression device. In the processing chamber 42 of an MVR evaporator, the liquid solution is heated, and some of the water evaporates into steam. Through recompression technology, the steam that would otherwise be released is reused and supplied to the heating elements inside the evaporator to complete the concentration or dehydration process.

[0056] In addition, a power component is provided on the conveyor belt 43 to drive the conveyor belt 43 to operate, and a first collection component 12 is provided on the side wall of the housing 41, with the end of the conveyor belt 43 connected to the first collection component 12.

[0057] Therefore, during operation, multi-concentration leachate enters the MVR evaporator processing chamber 42 from the output of the membrane reduction device 3. The MVR evaporator processing chamber 42 evaporates the leachate to remove moisture. The treated material is discharged from the output of the MVR evaporator processing chamber 42 and is located above the conveyor belt 43. The conveyor belt 43 is equipped with a power component, which drives the conveyor belt 43 to smoothly transport the treated solute concentrate. A first collection component 12 is provided on the side wall of the chamber 41, and the end of the conveyor belt 43 is connected to the first collection component 12 to ensure smooth collection of the treated material. Throughout the process, the integrated design of the MVR evaporator processing chamber 42 and the conveyor belt 43 improves processing efficiency, while the first collection component 12 helps to conveniently and reliably collect the treated solute concentrate, thus achieving the effects of efficient evaporation and drying and convenient collection of solute concentrate. Meanwhile, unlike traditional processes that generate heat by burning biomass, this application utilizes the waste heat generated by evaporation in the MVR evaporator processing box 42 to dry the solute concentrate, further removing moisture and achieving energy-saving effects.

[0058] Specifically, the conveyor belt 43 includes a support plate 431, a drive roller 432, a driven roller 433, and a conveyor belt 434. Two support plates 431 are provided, and a suspension rod 4311 is fixed to the top of each support plate 431. One end of the suspension rod 4311 is vertically fixed to the inner top wall of the housing 41. Correspondingly, the drive roller 432 and the driven roller 433 are rotatably supported between the two support plates 431. The conveyor belt 434 is fitted onto the drive roller 432 and the driven roller 433. The power component is a drive motor 5. A mounting bracket is fixed to the side wall of one of the support plates 431, and the drive motor 5 is mounted on the mounting bracket. A pulley transmission mechanism 6 is provided between the output shaft of the drive motor 5 and the drive roller 432. The two pulleys of the pulley transmission mechanism 6 are coaxially fixed to the output shaft of the drive motor 5 and the drive roller 432, respectively.

[0059] Therefore, during operation, after the drive motor 5 starts, it transmits power to the drive roller 432 under the action of the belt pulley transmission mechanism 6, causing it to rotate. This motion is transmitted to the driven roller 433 through the conveyor belt 434, causing the entire conveyor belt 43 to start operating. The supporting role of the bearing plate 431 ensures stable rotation between the drive roller 432 and the driven roller 433, while the function of the conveyor belt 434 is to smoothly convey the solute concentrate. This design realizes the operating mechanism of the conveyor belt 43: the drive motor 5 drives the conveyor belt 434 and the driven roller 433 through the rotation of the drive roller 432, thereby conveying the solute concentrate along the direction of the conveyor belt 43. Such a conveyor belt 43 structure design is simple, runs smoothly and reliably, and effectively completes the task of conveying the solute concentrate.

[0060] Furthermore, the surface of the conveyor belt 434 is provided with several air vents 4341. During the drying process, the air vents 4341 allow hot air to effectively penetrate into the solute concentrate, promoting faster evaporation of the solute. This design accelerates the transfer of moisture from the solute concentrate to the air, achieving a faster and more efficient drying process.

[0061] Furthermore, a rotating rod 7 is rotatably supported between the bearing plates 431. The rotating rod 7 is coaxially arranged with the output shaft of the drive motor 5. A separation rod 71 is circumferentially arranged on the outer wall of the rotating rod 7. Several sets of separation rods 71 ​​are arranged at intervals along the length direction of the rotating rod 7, and several sets of separation rods 71 ​​are circumferentially arranged on the rotating rod 7 within the coaxial direction.

[0062] Therefore, during operation, when the drive motor 5 starts, its output shaft transmits power to the coaxially mounted rotating rod 7. Since the outer wall of the rotating rod 7 is circumferentially equipped with a separating rod 71, as the rotating rod 7 rotates, the separating rod 71 passes through the adhered solute concentrate. This process is similar to a mechanical dispersing operation, helping to separate the adhered materials, making them easier to dry and process.

[0063] Meanwhile, in order to further improve the drying effect, a screw 8 and a guide rod 9 are also provided between the two bearing plates 431. The screw 8 is rotatable and a first transmission component is provided between the screw 8 and the drive motor 5. A brush 10 is threadedly connected to the screw 8 and is movably sleeved on the guide rod 9. The brush 10 is used to disperse the solute concentrate.

[0064] Correspondingly, during operation, the drive motor 5 starts, and through the action of the first transmission component, the screw 8 begins to rotate. This causes the brush 10 to move along the guide rod 9, and its movable sleeve allows for effective dispersion of the solute concentrate. The effect of this process is that, through the rotation of the screw 8 and the movement of the brush 10, effective dispersion of the solute concentrate is achieved, thus realizing effective treatment of the solute concentrate.

[0065] Specifically, the first transmission component is configured with two transmission gears 11, one of which is coaxially arranged with the output shaft of the drive motor 5, and the other transmission gear 11 is coaxially arranged with the screw 8.

[0066] Therefore, the coaxial arrangement of the transmission gear 11 achieves effective energy transfer and mechanical connection, enabling the rotational motion of the drive motor 5 to be transmitted to the screw 8. This coaxial transmission design improves the stability and efficiency of the system, ensuring that the power of the drive motor 5 is effectively converted into the rotational motion of the screw 8, thereby driving the entire process of dispersing and concentrating the solute.

[0067] On the other hand, the first collecting component 12 includes an inclined plate 121 and a first material box 122. The inclined plate 121 is installed inside the box body 41. A first opening 411 is provided on the side wall of the box body 41. One end of the inclined plate 121 is connected to the conveyor belt 43, and the other end of the inclined plate 121 extends out of the first opening 411. The first material box 122 is fixed to the outer side wall of the box body 41, and the other end of the inclined plate 121 is located above the first material box 122.

[0068] Therefore, the inclined plate 121 is installed inside the housing 41 and connected to the conveyor belt 43 through the first opening 411 on the side wall of the housing 41. The solute concentrate on the conveyor belt 43 is guided to the inclined plate 121, then moves along the inclined plate 121, and finally extends out from the first opening 411 of the housing 41, effectively collecting the solute concentrate from the conveyor belt 43 and transferring it to the hopper, providing an efficient and controllable solution for the safe storage of the concentrate.

[0069] Furthermore, the housing 41 is also provided with a second collection component 13, which includes a feeding plate 131 and a second material box 132. One end of the feeding plate 131 is rotatably supported inside the housing 41. A second transmission component is provided between the feeding plate 131 and the conveyor belt 43. A second opening 412 is provided on the side wall of the housing 41. The other end of the feeding plate 131 extends out of the second opening 412 and is located above the second material box 132.

[0070] Specifically, the second transmission component is configured as a crank-connecting rod mechanism 14, the turntable of the crank-connecting rod mechanism 14 is coaxially arranged with the driven roller 433, and the connecting rod of the crank-connecting rod mechanism 14 is hinged to the feed plate 131.

[0071] Therefore, some of the solute concentrate falling from the vent 4341 falls onto the feed plate 131. During the transmission process, the driving force is transmitted to the turntable of the crank-connecting rod mechanism 14 through the driven roller 433. Since the turntable of the crank-connecting rod mechanism 14 is coaxially arranged with the driven roller 433, the turntable of the crank-connecting rod mechanism 14 rotates with the movement of the driven roller 433. The connecting rod of the crank-connecting rod mechanism 14 is hinged to the feed plate 131, thereby converting the rotational motion into the linear motion of the feed plate 131. When the turntable of the crank-connecting rod mechanism 14 rotates, the hinge of the connecting rod of the crank-connecting rod mechanism 14 causes the feed plate 131 to begin to swing, guiding the solute concentrate to fall into the second material box 132. By introducing the second collection assembly 13, the system has a larger processing capacity and collection capacity, improving the efficient processing and centralized storage of the solute concentrate.

[0072] The implementation principle of the multi-concentration leachate full-volume modular treatment system in this application embodiment is as follows:

[0073] First, the pretreatment tank 1 enables the system to accommodate and treat leachate of multiple concentrations. Each pretreatment tank 1 is equipped with a water pump to transfer leachate of different concentrations between different pretreatment tanks 1, ensuring the system can flexibly adapt to liquids of various concentrations. Flow meter 2 is connected to the end pretreatment tank 1 to accurately monitor the liquid flow rate in the system. This helps control the flow rate of the liquid in the system and ensures the coordinated operation of each treatment unit. Membrane dewatering unit 3 incorporates a material separation membrane and a desalination membrane, which can effectively separate solutes and solids in leachate of different concentrations. This helps reduce membrane fouling, extend membrane life, and thus improve the stability and efficiency of the system. Evaporator-dryer 4 is connected to the output of membrane dewatering unit 3 for evaporating and drying leachate of multiple concentrations. This step helps evaporate water from the liquid, making solids easier to process or recycle. The detection device includes multi-functional detection sensors and controllers, distributed on pretreatment tank 1, membrane dewatering unit 3, and evaporator-dryer 4, for real-time monitoring of water quality and odor. This enables the system to possess intelligent control capabilities, allowing it to adjust the operating parameters of each processing unit in real time based on monitoring results, ensuring efficient operation under various conditions. Overall, this technical solution, through modular design and intelligent control, achieves comprehensive treatment of leachate of various concentrations, improving the system's adaptability and operational efficiency.
