A superconducting magnetic coagulation treatment device for high-concentration organic wastewater

Abstract

The present application relates to the technical field of organic wastewater treatment, in particular to a superconducting magnetic coagulation treatment device for high-concentration organic wastewater. The device comprises a sedimentation tank, a rotating cylinder is rotatably connected to the inside of the sedimentation tank, and two symmetrical spray heads are arranged on the outer wall near the top of the rotating cylinder. When facing stubborn and difficult-to-remove dry flocculation bodies by simple mechanical scraping, the scraping assembly moves upward under the extrusion force during contact with the flocculation bodies. The displacement change triggers the communication between the clean water channel in the rotating cylinder and the scraping assembly. As the scraping assembly moves upward, the water outlet of the spray head is opened, and clean water is symmetrically sprayed from the spray head. On the one hand, the dry flocculation bodies are directly moistened, reducing their adhesion strength and hardness, making them easier to peel off. On the other hand, the water flow impact force produces an additional loosening effect on the flocculation bodies, further assisting the scraping assembly to complete the cleaning task.

Description

Technical Field

[0001] This invention relates to the field of organic wastewater treatment technology, and more specifically, to a superconducting magnetic coagulation treatment device for high-concentration organic wastewater. Background Technology

[0002] The superconducting magnetic coagulation treatment device for high-concentration organic wastewater is a specialized device that uses the ultra-strong magnetic field generated by a superconducting magnet in combination with a coagulation process to treat high-concentration organic wastewater. It enhances the formation and separation of magnetic flocs through the action of the magnetic field, thereby improving the wastewater purification efficiency. It is suitable for the treatment of high-concentration organic wastewater generated in industries such as chemical, pharmaceutical, and printing and dyeing.

[0003] Currently, high-concentration organic wastewater treatment mainly employs physical, chemical, and biological methods. Among these, magnetic coagulation sedimentation technology has attracted widespread attention due to its highly efficient solid-liquid separation capabilities. This technology involves adding magnetic media and coagulants to the wastewater to cause pollutants to form magnetic flocs, accelerating sedimentation. However, in actual operation, some flocs, due to their strong viscosity, tend to adhere to the inner wall of the sedimentation tank or the outlet area, forming difficult-to-remove residual deposits. These attached flocs not only reduce sedimentation efficiency but may also cause outlet blockage, affecting the continuity and stability of the entire wastewater treatment process. Common sludge scraping devices mostly use a single mechanical scraping method, such as a rotary scraper or scraper plate, to clean the sediment at the bottom of the pool. However, they lack effective means to remove flocs attached to the pool walls and outlet area. Especially in complex areas such as the slopes and corners of the pool walls, cleaning blind spots are easily formed, leading to long-term accumulation of flocs. This can cause equipment malfunctions or require frequent manual intervention, increasing maintenance costs and downtime.

[0004] In addition, when traditional sludge scraping devices encounter stubborn flocs that are difficult to remove by rotation, they often rely on increasing mechanical force to peel them off, which can easily cause equipment wear and is difficult to effectively reduce the adhesion of flocs, resulting in low removal efficiency. In view of this, we propose a superconducting magnetic coagulation treatment device for high-concentration organic wastewater. Summary of the Invention

[0005] The purpose of this invention is to provide a superconducting magnetic coagulation treatment device for high-concentration organic wastewater, in order to solve the problems mentioned in the background art. It can achieve simultaneous and efficient removal of flocs on the inner wall of the sedimentation tank and in the outlet area. In particular, it can maintain good operating performance when dealing with highly viscous and strongly adhesive organic flocs, ensuring the continuity and efficiency of the wastewater treatment process.

[0006] To achieve the above objectives, the present invention provides a superconducting magnetic coagulation treatment device for high-concentration organic wastewater, comprising the sedimentation tank, characterized in that: a rotating cylinder is rotatably connected inside the sedimentation tank, two symmetrical nozzles are provided on the outer wall of the rotating cylinder near the top, and a scraping component is provided at the bottom of the rotating cylinder; The scraping component tends to the bottom of the sedimentation tank under the action of elasticity and rotates synchronously with the rotating cylinder. During the rotation, the scraping component has a force acting on the dry flocs that tends to the center of rotation of the scraping component, and a force that is continuously applied to the dry flocs in the vertical direction for reciprocating vibration under the action of elasticity. The scraping component moves upward under the pressure of the dried flocculent, causing the rotating drum and the scraping component to connect. The clean water in the rotating drum assists in the scraping of impurities under the action of gravity.

[0007] The beneficial effects of this invention are: 1. In this invention, the rotating drum and the scraping component are mechanically linked. The scraping component adheres to the bottom of the sedimentation tank by elasticity and continuously removes wet flocs as the rotating drum rotates, avoiding clogging of the outlet, preventing wastewater backflow, ensuring the continuous progress of the treatment process, improving treatment purity and reducing the risk of secondary pollution. At the same time, the clean water in the rotating drum, under the action of gravity and the elastic lifting rod, applies downward pressure to the scraping component, strengthening the scraping force of the stripping plate on the stubborn sediments at the bottom of the tank, ensuring that even difficult-to-treat flocs can be effectively removed.

[0008] 2. In this invention, when encountering dry and stubborn flocs, the scraping component is squeezed upwards, triggering the nozzle to open. The mechanical scraping and water impact form a dual treatment mechanism. The scraping component first breaks the floc attachment structure through physical contact, and the nozzle then sprays clean water to moisten the flocs, reducing their viscosity and hardness. The water flow impact further loosens the flocs, assisting the scraping component in its operation and reducing equipment operating resistance and mechanical wear. This dual effect not only improves cleaning efficiency and extends equipment service life, but also avoids floc residue affecting subsequent sedimentation effects, reduces the need for manual maintenance, and ensures the stable operation of the sewage treatment process.

[0009] As a further improvement to this technical solution, the scraping assembly includes a sliding sleeve slidably connected to the outer wall of the bottom end of the rotating cylinder. Peeling plates are fixedly connected to both sides of the sliding sleeve. Multiple obliquely placed conical teeth are arrayed along the length of the bottom surface of the peeling plates. Two moving blocks are fixedly connected to both sides inside the sliding sleeve. An elastic lifting rod is fixedly connected to the top of each of the two moving blocks, and a circular baffle is fixedly connected to the top of the elastic lifting rod. A fixed block is slidably connected to the outer wall of the bottom end of the circular baffle. The circular baffle is circular and adapted to the input end of the nozzle. The fixed block is fixedly connected inside the rotating cylinder, and its position is slightly lower than the input end of the nozzle.

[0010] The beneficial effects of adopting the above-mentioned further solution are that multiple oblique conical teeth are arrayed along the length of the bottom surface of the stripping plate. The oblique conical teeth, on the one hand, utilize concentrated stress to tear the flocs during rotation and downward movement; on the other hand, the oblique array creates a guiding force towards the rotation center, which can drive the flocs towards the rotation center of the stripping plate during rotation, thus making it easier for them to enter the discharge pipe. Furthermore, the sliding sleeve, in conjunction with the elastic lifting rod, allows the scraping component to adaptively adjust its height according to the thickness and hardness of the impurities at the bottom of the pool. When encountering stubborn deposits, the elastic lifting rod contracts under pressure, increasing the downward pressure of the stripping plate on the bottom of the pool and enhancing the scraping effect; while in areas with fewer impurities, it automatically rebounds, reducing unnecessary wear.

[0011] As a further improvement to this technical solution, the sedimentation tank is cone-shaped with a sloping bottom, and a sewage pipe is connected to the bottom of the sedimentation tank for connecting to an external sewage pump. As a further improvement to this technical solution, a support is fixedly connected to the top of the sedimentation tank, and the rotating cylinder rotates through the center of the support. A bearing is fixedly connected between the rotating cylinder and the outer wall of the support. The outer wall of the bearing is fixedly connected to the support, and the inner wall of the bearing is fixedly connected to the outer wall of the rotating cylinder, so as to realize the relative rotation of the rotating cylinder and the support. A first gear is fixedly connected to the outer wall of the rotating cylinder extending out of the bearing. A second gear is meshed on the outer wall of the first gear. The second gear is rotatably set on the top of the support. A cavity is opened inside the rotating cylinder, and a water supply pipe is rotatably connected to the top of the rotating cylinder. Sliding grooves are opened on both sides of the bottom end of the rotating cylinder for the movement of the scraping component. The outer wall of the elastic lifting rod is sealed and fits against the sliding groove for sliding. A solid column is also provided at the bottom of the inner cavity of the rotating cylinder. The outer wall of the elastic lifting rod away from the sliding groove is also sealed and fits against the outer wall of the solid column.

[0012] The beneficial effects of adopting the above-mentioned further solution are that the sliding groove provides motion guidance for the scraping component, ensuring that the stripping plate slides smoothly along the bottom of the sedimentation tank and precisely conforms to the bottom contour of the tank; while sealing, the elastic lifting rod can elastically extend and retract according to the resistance of the flocs, realizing adaptive adjustment of the height of the scraping component, which can not only enhance the scraping force on stubborn flocs, but also avoid equipment damage caused by rigid collisions.

[0013] 1. This superconducting magnetic coagulation treatment device for high-concentration organic wastewater, when faced with stubborn dry flocs that are difficult to remove by simple mechanical scraping, the scraping component moves upward under the pressure of compression during contact with the flocs. This displacement change triggers the connection between the clean water channel inside the rotating drum and the scraping component. As the scraping component moves upward, the water outlet of the nozzle is opened, and clean water is sprayed symmetrically from the nozzle. On the one hand, it directly wets the dry flocs, reducing their adhesion strength and hardness, making them easier to peel off; on the other hand, the water flow impact force produces an additional loosening effect on the flocs, further assisting the scraping component in completing the cleaning task. Specifically, the water jet from the nozzle provides a dual boost of wetting and softening, as well as physical impact, reducing scraping resistance, lowering the operating load of the equipment, thereby slowing down mechanical wear and extending the service life of the equipment.

[0014] 2. This superconducting magnetic coagulation treatment device for high-concentration organic wastewater uses a rotating drum to drive the bottom scraping component to rotate synchronously. Under the action of elasticity, the scraping component always runs in contact with the bottom of the sedimentation tank, which can continuously remove the wet flocs at the bottom of the tank and the outlet area, prevent them from accumulating and clogging the outlet, avoid wastewater backflow affecting the continuity of the treatment process, and effectively improve the treatment purity and reduce the risk of secondary pollution. At the same time, the clear water inside the rotating drum generates downward pressure under the action of gravity and the elastic lifting rod, causing the stripping plate to adhere more tightly to the inner wall of the bottom of the sedimentation tank. This enhances the scraping ability of the scraping component to scrape stubborn sediments at the bottom of the sedimentation tank. It can apply greater scraping force to the flocs attached to the bottom of the tank, effectively removing sediments that may have become particularly difficult to handle due to long-term accumulation.

[0015] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The present invention provides the following preferred embodiments. Please see Figures 1-10 As shown, this embodiment provides a superconducting magnetic coagulation treatment device for high-concentration organic wastewater, including a sedimentation tank 100, a rotating cylinder 200 rotatably connected inside the sedimentation tank 100, two symmetrical nozzles 300 arranged on the outer wall near the top of the rotating cylinder 200, and a scraping assembly 400 arranged at the bottom of the rotating cylinder 200. The scraping component 400 adheres to the bottom of the inner cavity of the sedimentation tank 100 under the action of elasticity and rotates synchronously with the rotating cylinder 200; The scraping component 400 is subjected to the squeezing force of the dry flocs (the dry flocs are stubborn flocs that cannot be scraped off by rotation) and moves upward, causing the rotating cylinder 200 and the scraping component 400 to be connected. The clean water in the rotating cylinder 200 assists in the scraping of impurities under the action of gravity.

[0020] Therefore, based on the above features, the improvements of the present invention will be described in detail: After wastewater flows into the superconducting magnetic coagulation treatment device, it first enters the coagulation zone. In this stage, a specific coagulant and superconducting magnetic medium are added to the wastewater. The two work synergistically to accelerate the formation of flocs. Subsequently, the formed flocs, driven by both gravity and magnetic field, enter the sedimentation zone for further treatment. During the sedimentation process, some flocs can be directly removed by the scraping mechanism; however, some more stubborn flocs that cannot be scraped off by rotation easily adhere to the inner wall of the sedimentation tank 100. If not treated in time, this will adversely affect the purity of the wastewater. Therefore, when the flocs in the sedimentation tank 100 are in a moist state, they can be directly scraped off the inner wall of the sedimentation tank 100 by the rotation drive of the rotating cylinder 200. The cleaning operation serves several purposes. First, it removes the wet flocculent material from the inner wall and outlet of the sedimentation tank 100, significantly improving overall cleaning efficiency, shortening the time for each cleaning cycle, accelerating the wastewater treatment process, and ensuring continuous and stable operation of the treatment unit. Second, timely removal of flocculent material from the outlet of the sedimentation tank 100 effectively prevents the accumulation of flocculent material from clogging the outlet channel, avoiding wastewater backflow due to obstructed outlets, thus ensuring the normal progress of the wastewater treatment process, improving treatment purity, and reducing the risk of secondary pollution. In addition, the downward elasticity of the scraping component 400 and the gravity of the water accumulated inside the rotating cylinder 200 further enhance the scraping pressure, ensuring that the stripping plate 402 generates sufficient scraping force on stubborn deposits, effectively removing the flocculent material attached to the bottom of the tank. When stubborn flocs that cannot be removed by rotation appear in the sedimentation tank 100, the rotating cylinder 200 drives the scraping component 400 to scrape the stubborn flocs. During this process, the upward pressure generated by the scraping component 400 triggers the outlet of the nozzle 300 to open, fully wetting the flocs and making them easier to handle. At the same time, the impact force of the water sprayed from the nozzle 300 falling to the bottom of the sedimentation tank 100 further impacts the stubborn flocs. Through the linkage of mechanical scraping and water impact, a powerful effect is achieved... The dual-treatment mechanism for stubborn flocs significantly improves the cleaning efficiency and effectiveness of sedimentation tank 100. The rotating drum 200 drives the scraping component 400 to mechanically scrape, directly targeting stubborn flocs that cannot be removed by rotation, thus breaking down their attachment structure. During this process, the scraping component 400 triggers the spray nozzles 300 to spray water, wetting the flocs and reducing their viscosity and hardness, making them easier to scrape or rinse. Simultaneously, the external force generated by the water flow further loosens the flocs, assisting the scraping component 400 in its work, reducing equipment operating resistance, and minimizing mechanical wear. This dual-action approach not only improves cleaning efficiency and shortens cleaning time but also avoids excessive equipment wear that might result from single mechanical cleaning, extending equipment lifespan. Furthermore, thorough wetting and impact ensure the complete removal of flocs, preventing residues from affecting subsequent sedimentation in sedimentation tank 100, ensuring stable operation of the wastewater treatment process, and reducing the frequency of manual intervention and maintenance costs.

[0021] Based on the above, the specific structure will be disclosed in detail: To address the issues related to the sedimentation stage of organic wastewater, the structure of sedimentation tank 100 is disclosed in detail, as follows: Figure 2 and Figure 3 As shown, the sedimentation tank 100 is generally conical with a sloping bottom. A drain pipe 101 is connected to the bottom of the sedimentation tank 100 for connecting to an external sludge pump. Thanks to the conical structure design of the sedimentation tank 100, when the scraping component 400 scrapes the flocs, the detached flocs can slide down to the outlet of the sedimentation tank 100 by their own gravity and the sloping surface. Then, the sludge pump starts working and efficiently removes the flocs collected at the outlet, completing the cleaning process.

[0022] The scraping component 400 is designed to scrape away the flocs adhering to the bottom of the inner cavity of the sedimentation tank 100, such as... Figures 3-6 As shown, the specific structure of the scraping assembly 400 is further disclosed. The scraping assembly 400 includes a sliding sleeve 401 slidably connected to the outer wall of the bottom end of the rotating cylinder 200. A stripping plate 402 is fixedly connected to both sides of the sliding sleeve 401. The stripping plate 402 has an inclined angle adapted to the bottom of the conical inner cavity of the sedimentation tank 100. Multiple obliquely placed conical teeth 407 are arrayed along the length direction on the bottom surface of the stripping plate 402. The angle between the obliquely placed conical teeth 407 and the length direction of the stripping plate 402 is 60°. The obliquely placed conical teeth 407 are provided with ridges 408 that face the flocs during downward movement and rotation. These ridges are used to tear the flocs using concentrated stress when in contact with them, preventing excessive accumulation of flocs and increased resistance during scraping. The oblique arrangement of the obliquely placed conical teeth 407 can form a guiding force towards the rotation center, which can drive the flocs towards the rotation center of the stripping plate during rotation, making it easier for them to enter the discharge pipe, reducing accumulation, and improving treatment efficiency. When the rotating cylinder 200 rotates, the sliding sleeve 401 and the peeling plate 402 on the rotating cylinder 200 can rotate accordingly with the external drive. Since the tilt angle of the peeling plate 402 is adapted to the tilt angle of the bottom of the conical inner cavity of the sedimentation tank 100, it can continuously scrape off the sludge, impurities and other sediments attached to the bottom of the tank during the movement, and thoroughly peel off the sludge and impurities deposited in the corners and bottom, avoiding dead corner residues and greatly improving cleaning efficiency. At the same time, the design of the inclined conical teeth 407 reduces the resistance during the cleaning process, reduces the energy consumption of the equipment, extends the service life of the equipment, and also reduces the cost and difficulty of manual secondary cleaning, ensuring the continuous and efficient operation of the sedimentation tank 100.

[0023] It is worth noting that, to achieve the goal of removing impurities that cannot be scraped off by rotating the peeling plate 402, two moving blocks 403 need to be fixedly connected to both sides inside the sliding sleeve 401. Each of the two moving blocks 403 has an elastic lifting rod 404 fixedly connected to its top, and a circular baffle 405 is fixedly connected to the top of the elastic lifting rod 404. A fixed block 406 is slidably connected to the outer wall of the bottom end of the circular baffle 405. The elastic lifting rod 404 includes an inner rod fixedly connected to the bottom of the circular baffle 405. An outer rod is slidably connected to the outer wall of the inner rod, and a return spring is fixedly connected to the bottom of the inner rod. The bottom end of the return spring is connected to the inner bottom wall of the outer rod, and the bottom surface of the outer rod is connected to the top surface of the moving block 403. By utilizing the stiffness of the return spring or the damping structure (a hydraulic buffer composed of the inner and outer rods), the reset time is delayed, ensuring that the water spray continues for a sufficient time (e.g., 2-3 seconds). When the rotation speed of the rotating cylinder 200 increases, the centrifugal force can increase the water pressure, making the nozzle 300 spray more violently and compensating for insufficient gravity pressure. When encountering stubborn flocs that cannot be removed by rotation, the elastic lifting rod 404 is lifted upwards by the fixed block 406, connecting the rotating cylinder 200 and the nozzle 300. Water is sprayed out from the nozzle 300 under gravity, softening the stubborn flocs that cannot be removed by rotation. At the same time, the impact force of the water sprayed from the nozzle 300 and falling to the bottom of the inner cavity further impacts the stubborn flocs. On the one hand, the water flow directly softens the flocs, reducing their adhesion and hardness, weakening the bond strength between the stubborn flocs and the bottom of the pool, making subsequent scraping easier. On the other hand, the external force generated by the water flow impact can impact the flocs from multiple angles, assisting the scraping component 400 in loosening and separating stubborn substances, and avoiding increased equipment wear due to excessive mechanical scraping. The clean water inside the rotating cylinder 200 assists in scraping away impurities under the action of gravity, mainly relying on the water level difference (height of the rotating cylinder 200) to provide water pressure; and when the rotating cylinder 200 rotates at high speed, centrifugal force will generate additional pressure on the internal water, enhancing the spray force of the nozzle 300. In addition, to ensure the balance between close scraping and lifting water spray, centrifugal force control and rigidity design of the elastic lifting rod 404 are also required.

[0024] Centrifugal force control: By limiting the rotation speed of the rotating drum 200 (e.g., ≤50RPM), the centrifugal force is insufficient to overcome the return spring force, ensuring that the peeling plate 402 adheres to the bottom of the pool under normal conditions.

[0025] Stiffness design of the 404 flexible lifting rod: Spring preload must meet the following requirements: Normal condition: Spring force > centrifugal force + structural gravity, ensuring close scraping.

[0026] When encountering resistance: the pressure of the stain plus the centrifugal force exceeds the spring force, triggering the lifting and spraying of water.

[0027] The opening and closing logic of nozzle 300: nozzle 300 will only be opened when the lifting height reaches a threshold (e.g., 5mm) to avoid accidental triggering by slight vibration; after water spraying, the reset spring will slowly return to its original position to prolong the water spraying time and enhance the impact effect.

[0028] The circular baffle 405 is circular and adapted to the input end of the nozzle 300. The fixing block 406 is fixedly connected to the inside of the rotating cylinder 200. The position of the fixing block 406 is slightly lower than the position of the input end of the nozzle 300. The circular structure of the circular baffle 405 is fully adapted to the input end of the nozzle 300. When the elastic lifting rod 404 is in the initial position, the baffle and the fixing block 406 are tightly fitted to form a mechanical seal, preventing clean water in the rotating cylinder 200 from flowing into the nozzle 300 when not in operation, thus avoiding water waste and disturbance to the sedimentation zone.

[0029] Furthermore, to achieve the rotation of the rotating cylinder 200, it is necessary to provide power to the rotating cylinder 200, specifically as follows: Figure 7 As shown, a support is fixedly connected to the top of the sedimentation tank 100. A rotating cylinder 200 rotates through the center of the support, and a bearing is fixedly connected between the rotating cylinder 200 and the outer wall of the support. The outer wall of the bearing is fixedly connected to the support, and the inner wall of the bearing is fixedly connected to the outer wall of the rotating cylinder 200, enabling relative rotation between the rotating cylinder 200 and the support. The support is a hydraulic lifting support. When not in use, the scraping component 400 is kept at a clean water level to prevent impurities from entering the gaps and connections at the lower end of 200.

[0030] A first gear 201 is fixedly connected to the outer wall of the rotating cylinder 200 extending from the bearing. A second gear 202 is meshed on the outer wall of the first gear 201. The second gear 202 is rotatably mounted on the top of the support. The shaft of the second gear 202 is fixedly connected to the output shaft of the drive motor. The output shaft of the drive motor drives the second gear 202 to rotate, causing the first gear 201 to mesh and rotate synchronously. This rotation helps to achieve higher strength of the stripping plate 402 scraping the flocs. The shearing force generated by the high-strength scraping can effectively break the adhesion between the flocs and the sedimentation tank 100. Especially for highly viscous or compacted flocs, the stripping efficiency is significantly improved, avoiding clogging.

[0031] Specifically, to ensure that the rotating drum 200 contains a clean water source, such as... Figure 9As shown, the rotating cylinder 200 has an internal cavity, and a water supply pipe is rotatably connected to the top of the rotating cylinder 200. External water is introduced into the rotating cylinder 200 for storage through the input pipe. Sliding grooves 203 are provided on both sides of the bottom of the rotating cylinder 200 for the movement of the scraping component 400. When the scraping component 400 comes into contact with the stubborn flocs in the sedimentation tank 100, it will be displaced due to the force and move along the sliding grooves 203 on the rotating cylinder 200. During the movement, the scraping component 400 triggers the opening mechanism of the spraying component, causing the outlet of the spraying component to open and spray liquid onto the surface of the stubborn flocs that cannot be scraped by rotation, so as to fully wet them and create favorable conditions for subsequent cleaning operations.

[0032] To prevent impurities from entering the inner cavity of the rotating cylinder 200, specifically as follows: Figure 8 and Figure 9 As shown, the outer wall of the elastic lifting rod 404 is sealed against the sliding groove 203, and a solid column 4031 is also provided at the bottom of the inner cavity of the rotating cylinder 200. The outer wall of the elastic lifting rod 404 away from the sliding groove 203 is also sealed against the outer wall of the solid column 4031. The outer wall of the elastic lifting rod 404 simultaneously adheres to both the sliding groove 203 and the solid column 4031, forming a double sealing structure of "axial + radial". When the rotating cylinder 200 rotates at high speed, it can effectively prevent sewage, sludge and other media inside the cylinder from leaking from the gap of the sliding groove 203 or around the bottom solid column 4031.

[0033] The working steps of this invention are as follows: In the coagulation zone, a specific coagulant and a superconducting magnetic medium are added to the wastewater and reacted. The high-concentration organic wastewater then enters the sedimentation tank 100 through the inlet channel. When the drive motor starts, it drives the second gear 202 to rotate. Through meshing with the first gear 201, the rotating cylinder 200 starts to rotate. When the flocs in the sedimentation tank 100 are in a wet state, the rotating cylinder 200 drives the oblique stripping plate 402 of the scraping component 400 to rotate. The stripping plate 402 is attached to the inclined surface of the inner wall of the sedimentation tank 100 to scrape off the flocs on the inner wall. If stubborn flocs that cannot be removed by rotation are encountered, when the stripping plate 402 scrapes the raised part, it will drive the sliding sleeve 401 to move upward, which will cause the moving block 403 to move along the sliding groove 203 of the rotating cylinder 200, pulling the elastic lifting rod 404 to rise. The circular baffle 405 will rise accordingly, and the nozzle 300 will be opened to wet the flocs. At this time, the elastic lifting rod 404 is compressed. When the stripping plate 402 rotates to the wet area, the elastic lifting rod 404 releases its elasticity and drives the stripping plate 402 to reset, continuing to closely adhere to the pool wall for cleaning. Finally, the scraped flocs slide down the inclined surface of the conical structure of the sedimentation tank 100 under the action of gravity to the sewage pipe 101, where they are pumped out by the sewage pump.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
