[0001] The present invention relates to the technical field of water resource treatment, and particularly to a municipal engineering water treatment emergency system and device based on digital twin. Background Art

[0002] With the acceleration of the urbanization process, municipal engineering water treatment is facing more and more challenges. From water source protection, water supply scheduling to sewage treatment, efficient and intelligent management methods are required in each link. Especially in emergency situations, how to quickly respond, effectively dispatch resources, and ensure water quality safety has become an urgent problem to be solved. Therefore, it is particularly important to develop a municipal engineering water treatment emergency system and device based on digital twin.

[0003] In the prior art, municipal engineering has begun to use digital twin technology to construct water treatment emergency systems. Such systems can often monitor the water resources in the city, such as water temperature, water pressure, water quality, and water reserves. Staff can construct corresponding emergency plans based on their own experience according to these data. However, the water treatment emergency systems in the prior art can only monitor various data of water resources, lack the reasonable construction and optimization of emergency plans, and still require staff to construct emergency plans by themselves, resulting in low efficiency of water treatment work.

[0004] In summary, how to solve the problem that the water treatment emergency system in the prior art can only monitor various data of water resources, lacks the reasonable construction and optimization of emergency plans, and leads to low efficiency of water treatment work has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose a reasonable municipal engineering water treatment emergency system and device based on digital twin. Summary of the Invention

[0005] To solve the above problems, the present invention provides a municipal engineering water treatment emergency system and device based on digital twin. Through the design of the water condition monitoring module, the water source quality, water source margin of the water resources treated by the municipal sewage treatment plant, and the operating status of various water treatment devices are monitored in real time. Then, using the water condition prediction module, according to the dynamic changes of the historical water source quality, water source margin, and the operating status of various water treatment devices in the water condition database, an emergency plan is constructed and optimized. Then, using the emergency treatment module, the emergency plan is implemented. Thus, the efficiency of water resource emergency treatment is effectively improved.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A municipal engineering water treatment emergency system based on digital twin, comprising a water condition monitoring module, a water condition prediction module, and an emergency treatment module.

[0007] The water situation monitoring module is used to monitor the water source quality, water source surplus of the water resources after being treated by the municipal sewage treatment plant, and the operating status of various water treatment equipment, and transmit the water source quality, water source surplus, and the operating status of various water treatment equipment to the water situation prediction module in real time; the water situation monitoring module is also used to store the water source quality, water source surplus, and the operating status of various water treatment equipment of the water resources after being treated by the municipal sewage treatment plant as historical data to form a water situation database; the water situation database stores past emergency plans.

[0008] The water situation prediction module is used to construct a virtual urban water network based on the historical water source quality, water source surplus, and the operating status of various water treatment equipment in the water situation database; the water situation prediction module is also used to retrieve the historical data with the highest similarity in the water situation database according to the current water source quality, water source surplus, and the operating status of various water treatment equipment of the water resources after being treated by the municipal sewage treatment plant, combine the historical emergency plan of the historical data, generate several simulated emergency plans, and implement the several simulated emergency plans to the virtual urban water network respectively, and compare the water situation changes after the several simulated emergency plans are implemented respectively to obtain the optimal plan; the water situation prediction module then adjusts according to the optimal plan to generate an actual emergency plan and transmit the actual emergency plan to the emergency treatment module.

[0009] The emergency treatment module is used to receive the actual emergency plan transmitted by the water situation prediction module, perform emergency treatment according to the actual emergency plan, and adjust the water source quality, water source surplus, and the operating status of various water treatment equipment of the water resources after being treated by the municipal sewage treatment plant.

[0010] Furthermore, the water situation monitoring module includes a water quality monitoring unit, a water volume monitoring unit, and a equipment monitoring unit.

[0011] The water quality monitoring unit is used to monitor the composition and pH value of the water source, evaluate the water quality according to the composition and pH value of the water source, generate a water quality evaluation report, and generate a water quality control instruction according to the water quality evaluation report.

[0012] The water volume monitoring unit is used to monitor the surplus and demand of the water source, calculate the maximum supply time according to the surplus and demand of the water source, and generate a water volume control instruction according to the maximum supply time.

[0013] The equipment monitoring unit is used to monitor the operating status of various water treatment equipment, and generate an equipment control instruction for adjusting the operating status of the water treatment equipment according to the operating status of various water treatment equipment and the demand of the city.

[0014] Furthermore, the emergency treatment module includes a water quality adjustment unit, a water volume adjustment unit, and a equipment adjustment unit.

[0015] The water quality regulation unit is used to receive water quality regulation instructions and, according to the water quality regulation instructions, use water treatment equipment to adjust the composition and pH value of the water source.

[0016] The water volume regulation unit is used to receive water volume regulation instructions and, according to the water volume regulation instructions, use water treatment equipment to adjust the remaining amount of the water source.

[0017] The equipment regulation unit is used to receive equipment regulation instructions and, according to the equipment regulation instructions, regulate the operating state of the water treatment equipment.

[0018] Furthermore, the water treatment equipment includes water quality regulation equipment, water source replacement equipment, and water volume regulation equipment.

[0019] The technical principle of the above solution is as follows:

[0020] Through the water situation monitoring module, the water source quality, water source remaining amount, and operating states of various water treatment equipment of the water resources treated by the municipal sewage treatment plant are collected in real time, and the water source quality, water source remaining amount, and operating states of various water treatment equipment of the water resources treated by the municipal sewage treatment plant are used to form the basis of the water situation database. Based on the water source quality, water source remaining amount, and operating states of various water treatment equipment of the water resources treated by the municipal sewage treatment plant collected by the water situation monitoring module, the water situation prediction module constructs a virtual urban water network accordingly; then, according to the dynamic changes in the current water source quality, water source remaining amount, and operating states of various water treatment equipment in the city, combined with past emergency plans, a simulated emergency plan is generated and implemented into the virtual urban water network. According to the changes in the virtual urban water network, the simulated emergency plan is optimized, and then a reasonable actual emergency plan is obtained; finally, through the emergency treatment module, the water source quality, water source remaining amount, and operating states of various water treatment equipment of the water resources treated by the municipal sewage treatment plant are adjusted according to the actual emergency plan.

[0021] Adopting the above solution has the following beneficial effects:

[0022] 1. Through the design of the water situation monitoring module, the present invention can monitor the water source quality, water source remaining amount, and operating states of various water treatment equipment of the water resources treated by the municipal sewage treatment plant in real time, and at the same time establish a water situation database, greatly improving the control ability of the water resources situation in the city; once an abnormal situation is found, the water situation monitoring module can detect it in time, thus providing a good data basis for the subsequent water resources emergency treatment work.

[0023] 2. Through the design of the water situation prediction module, the present invention utilizes the historical data in the water situation database to construct a virtual urban water network, simulating the operation of urban water resources. Then, by comparing the current data with the historical data, an emergency plan applicable to the current data is searched from the water situation database to generate a simulated emergency plan. Furthermore, by implementing the simulated emergency plan into the virtual urban water network for simulation experiments, based on the experimental situation, the simulated emergency plan can be optimized and adjusted, thereby generating a practical emergency plan more suitable for the current urban situation, and effectively improving the efficiency and success rate of emergency handling.

[0024] 3. The water treatment emergency system in the prior art only provides a data basis for operators by monitoring various data, and cannot provide a reasonable emergency plan for operators. Operators need a large amount of emergency experience to construct a reasonable emergency plan, and cannot make mistakes for trial, which is not convenient for plan optimization. Through the design of the water situation prediction module, the present invention can reasonably construct a virtual urban water network, generate a simulated emergency plan, greatly avoid the situation where operators cannot construct an emergency plan due to insufficient experience, and can make repeated mistakes for trial, thus being able to better construct and optimize the emergency plan, and improving the efficiency and success rate of emergency handling.

[0025] Furthermore, a municipal engineering water treatment emergency device based on digital twin includes a controller and a filter tank. The two side walls of the filter tank are respectively communicated with an input pipe for water inlet and a connecting pipe for transmitting water flow. A filter plate for filtering pollutants is slidably fitted on the inner wall of the filter tank. A sliding groove for the filter plate to slide is opened at the bottom of the filter tank, and telescopic plates are symmetrically and fixedly connected in the sliding groove. The output ends of the telescopic plates are fixedly connected to the filter plate. A driving component for driving the filter plate to move is provided at the bottom of the filter plate. A purification tank is provided at the bottom of the driving component. A purification component for purifying water resources is provided in the purification tank.

[0026] The end of the connecting pipe away from the filter tank is communicated with the side wall of the purification tank, and an output pipe for draining water is provided on the side wall of the purification tank.

[0027] Beneficial effects: The water flow is introduced into the filter tank through the input pipe. The water flow will pass through the filter plate, and the filter plate will intercept the pollutants with larger volume in the water flow, thereby preliminarily purifying the water flow. During this process, the filter plate will reciprocally move along the inner side wall of the filter tank under the drive of the driving component. Thus, while intercepting pollutants, relative movement will occur with the pollutants, avoiding the blockage of the filter plate by pollutants and preventing the water flow from passing through. During this process, the telescopic plates on both sides of the filter plate will expand and contract as the filter plate moves, effectively sealing the filter tank and preventing the water flow from flowing out.

[0028] The water flow filtered by the filter plate will flow into the purification tank through the connecting pipe and be further purified by the purification component.

[0029] Furthermore, the driving component includes a sliding box fixedly connected to the bottom of the filter box, and the bottom of the sliding box is fixedly connected to the top of the purification box; a sliding plate is slidably fitted on the sliding box; the sliding plate is fixedly connected to the bottom of the filter plate; a driving member is embedded and installed in the sliding box, the output shaft of the driving member is fixedly connected to a first eccentric rod, the first eccentric rod is fixedly connected to a central rod on the side away from the driving member, and a main gear is fixedly sleeved on the central rod; a second eccentric rod is rotatably connected to the bottom of the sliding plate, the second eccentric rod is fixedly connected to a connecting rod on the side away from the sliding plate, and a sub-gear is fixedly sleeved on the connecting rod; a hinged rod is rotatably fitted on the connecting rod, and the end of the hinged rod away from the connecting rod is rotatably fitted with the central rod; a moving groove for the rotation of the output shaft of the driving member and the movement of the connecting rod is opened at the top of the purification box; the controller is used to control the operation of the driving member, and thus control the rotation of the first eccentric rod.

[0030] Beneficial effects: By starting the driving member through the controller, the output shaft of the driving member will drive the first eccentric rod to rotate, the first eccentric rod will drive the central rod to revolve, and the central rod will drive the main gear to revolve; at the same time, since both the central rod and the connecting rod are hinged to the hinged rod, the central rod will pull the connecting rod to move together. During this process, the connecting rod will pull the second eccentric rod to move, and then pull the sliding plate to slide along the sliding box, and then make the filter plate slide along the inner wall of the filter box.

[0031] At the same time, due to the limitation of the hinged rod on the connecting rod and the central rod, the main gear and the sub-gear will continuously remain meshed. When the main gear rotates, it will drive the sub-gear to rotate in the opposite direction at the same speed; thus, the second eccentric rod will rotate, further expanding the moving range of the filter plate.

[0032] Furthermore, the purification component includes a feeding port opened on the side wall of the purification box; stirring rods are fixedly connected to the bottoms of both the central rod and the connecting rod; a control valve is connected to the connection between the output pipe and the purification box, and the controller is used to control the opening and closing of the control valve, and thus control the drainage of the purification box.

[0033] Beneficial effects: After the water flow flows into the purification box, at this time, sewage treatment additives such as acid-base regulators, coagulants, and flocculants are added into the purification box through the feeding port. Keep the driving member running. Due to the rotation of the first eccentric rod and the second eccentric rod, the central rod and the connecting rod will also rotate in a large range, and then can drive the stirring rods to rotate in a large range, so as to stir and mix the water flow and sewage treatment additives in the purification box in a large range, and the water flow can be further purified. And during this process, since the main gear and the sub-gear will rotate in the opposite direction at the same speed, the stirring rods at the bottoms of the central rod and the connecting rod will also rotate in the opposite direction at the same speed, so that the water flow in the purification box will form two vortices with different rotation directions, collide with each other, increase the turbulence of the water flow, improve the mixing effect of the water flow and sewage treatment additives, and then make the water flow and sewage treatment additives in the purification box more uniform, and improve the purification effect of the water flow.

[0034] Further, a cleaning opening for cleaning pollutants is formed on the side wall of the filtering tank, and a sealing cover plate is hinged to the cleaning opening.

[0035] Beneficial effects: After each water flow purification, the operator can open the sealing cover plate to remove the sundries filtered by the filter plate from the cleaning opening, and at the same time, the equipment inside the filtering tank can be repaired through the cleaning opening.

[0036] Further, a protective frame for shielding the moving groove is fixedly connected to the bottom of the filtering tank; the bottom of the protective frame is fixedly connected to the top of the purification tank.

[0037] Beneficial effects: The protective frame can shield the moving groove, thereby preventing impurities from entering the purification tank through the moving groove to pollute the water flow, and at the same time, it can also protect each component and improve the overall operation stability of the device.

[0038] Further, a rubber layer is fixedly connected to the side wall of the sliding groove.

[0039] Beneficial effects: The rubber layer can further improve the sealing performance of the filtering tank and prevent the water flow from flowing out.

[0040] The additional aspects and advantages of the present invention will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present invention. Description of the Drawings

[0047] The following is a further detailed description through specific implementation modes:

[0048] Example 1:

[0049] As Figure 1 shown, a municipal engineering water treatment emergency system based on digital twin includes a water condition monitoring module for monitoring water conditions, a water condition prediction module for predicting water conditions, and an emergency treatment module for treating water conditions; each module is connected by signals to each other.

[0050] The specific functions of each module are as follows:

[0051] The water condition monitoring module is used to monitor the water source quality, water source surplus of the water resources treated by the municipal sewage treatment plant, and the operating status of various water treatment equipment, and transmit the water source quality, water source surplus, and the operating status of various water treatment equipment to the water condition prediction module in real time; the water condition monitoring module is also used to store the water source quality, water source surplus, and the operating status of various water treatment equipment of the water resources treated by the municipal sewage treatment plant as historical data to form a water condition database; past emergency plans are stored in the water condition database. In this embodiment, the water condition monitoring module mainly uses a memory to store various data to construct a water condition database.

[0052] The water condition monitoring module includes a water quality monitoring unit, a water volume monitoring unit, and an equipment monitoring unit.

[0053] Among them, the water quality monitoring unit is used to monitor the composition and pH value of the water source, evaluate the water quality according to the composition and pH value of the water source, generate a water quality evaluation report, and generate a water quality regulation instruction according to the water quality evaluation report. In this embodiment, the water quality monitoring unit uses a composition analyzer and a pH value detector to realize the monitoring of the composition and pH value of the water source.

[0054] The water volume monitoring unit is used to monitor the surplus and demand of the water source, calculate the maximum supply time according to the surplus and demand of the water source, and generate a water volume regulation instruction according to the maximum supply time, so that the surplus of the water source can continuously meet the supply to the city.

[0055] For example, let the current water source surplus be X tons, the daily demand of the city be Y tons, the maximum supply time be T, and the dynamic change parameter of the water source be K. Then the calculation formula for the maximum supply time T is as follows:

[0056] T = (X + K) / Y (1).

[0057] Among them, the dynamic change parameter of the water source, K, is related to factors such as rainwater increment, water source evaporation, and loss.

[0058] The equipment monitoring unit is used to monitor the operating status of various water treatment equipment, and generate equipment control instructions for adjusting the operating status of the water treatment equipment according to the operating status of various water treatment equipment and the demand of the city. In this embodiment, the equipment monitoring unit mainly monitors the current power of each water treatment equipment through a power meter. If the water treatment equipment reaches its working power, it is determined that the water treatment equipment is in an operating state; if the current power of the water treatment equipment does not reach its working power, it is determined that the water treatment equipment is in a non-operating state.

[0059] The water situation prediction module is used to construct a virtual urban water network based on the historical water source quality, water source surplus, and the operating status of various water treatment equipment in the water situation database; the water situation prediction module is also used to retrieve the historical data with the highest similarity in the water situation database according to the current water source quality, water source surplus, and the operating status of various water treatment equipment after being treated by the current municipal sewage treatment plant, combine the historical emergency plan of the historical data, generate several simulated emergency plans, and implement the several simulated emergency plans to the virtual urban water network respectively, and compare the water situation changes after the several simulated emergency plans are implemented respectively, so as to obtain the optimal plan; the water situation prediction module then adjusts according to the optimal plan to generate an actual emergency plan, and transmits the actual emergency plan to the emergency treatment module. The water situation prediction module will also send the actual emergency plan to the staff display terminal, such as the staff's mobile phone or computer, etc., so that the staff can further adjust and optimize the actual emergency plan.

[0060] In this embodiment, the water situation prediction module is based on the digital twin technology, obtains the actual operation situation of the urban water network according to the data collected by the water situation monitoring module, and then uses the three-dimensional modeling technology to establish a virtual urban water network according to the actual operation situation of the urban water network. Based on the deep learning algorithm, learn the historical data in the water situation database, so as to realize generating and adjusting simulated emergency plans according to the current water source quality, water source surplus, and the operating status of various water treatment equipment.

[0061] The emergency treatment module is used to receive the actual emergency plan transmitted by the water situation prediction module, conduct emergency treatment according to the actual emergency plan, and adjust the water source quality, water source surplus of the water resources treated by the municipal sewage treatment plant, and the operating status of various water treatment devices. The specific treatment means of the stress treatment module mainly include the following solutions: 1. Start the water transfer pump to control the input and output of water flow; 2. Adjust the water residence time of the water treatment device to control the treatment effect and duration of water treatment; 3. Adjust the drug formula and drug dosage according to different water qualities; The emergency treatment module is signal-connected to the central control SCADA of the municipal sewage treatment plant.

[0062] The emergency treatment module includes a water quality adjustment unit, a water volume adjustment unit, and a device adjustment unit.

[0063] The water quality adjustment unit is used to receive the water quality control instruction, and according to the water quality control instruction, use the water treatment device to adjust the composition and pH value of the water source. In this embodiment, the main components of the water source to be adjusted mainly include ammonia nitrogen content, total phosphorus content, COD content, total nitrogen content, and DO content.

[0064] The water volume adjustment unit is used to receive the water volume control instruction, and according to the water volume control instruction, use the water treatment device to adjust the surplus of the water source.

[0065] The device adjustment unit is used to receive the device control instruction, and according to the device control instruction, regulate the operating status of the water treatment device.

[0066] The water treatment device includes a water quality adjustment device, a water source replacement device, and a water volume adjustment device. In this embodiment, the water quality adjustment device mainly includes softeners, filters, ultraviolet disinfection devices, etc. in the prior art; the water source replacement device mainly includes water supply networks, water source switching valves, etc. in the prior art; the water volume adjustment device mainly includes flow meters, booster pumps, pressure reducing valves, gates, and water storage tanks and reservoirs, etc. in the prior art. The emergency treatment module realizes the adjustment of the water source quality and water source surplus of the water resources treated by the municipal sewage treatment plant by regulating the operating status of these devices.

[0067] The water situation monitoring module can quickly adjust the water source quality, water source surplus, and the operating status of various water treatment devices by issuing water quality adjustment instructions, water volume adjustment instructions, and device adjustment instructions to the emergency treatment module; while the water situation prediction module can provide a more perfect emergency plan and conduct more reasonable regulation of the water source quality, water source surplus, and the operating status of various water treatment devices, thereby improving the efficiency and success rate of water treatment emergency in municipal engineering.

[0068] In this embodiment, through the design of the water situation prediction module, historical data in the water situation database is utilized to construct a virtual urban water network to simulate the operation of urban water resources. Then, the current data is compared with the historical data, and an emergency plan applicable to the current data is searched from the water situation database to generate a simulated emergency plan. By implementing the simulated emergency plan into the virtual urban water network for simulation experiments, based on the experimental situation, the simulated emergency plan can be optimized and adjusted, thereby generating an actual emergency plan more suitable for the current urban situation, and effectively improving the efficiency and success rate of emergency handling.

[0069] The water treatment emergency system in the prior art only provides a data basis for operators by monitoring various data and cannot provide a reasonable emergency plan for operators. Operators need a large amount of emergency experience to construct a reasonable emergency plan, and they cannot make mistakes for trial, which is not convenient for optimizing the plan. Through the design of the water situation prediction module, the present invention can reasonably construct a virtual urban water network, generate a simulated emergency plan, greatly avoid the situation where an emergency plan cannot be constructed due to insufficient operator experience, and can conduct repeated trial and error, thereby better constructing and optimizing the emergency plan, and improving the efficiency and success rate of emergency handling.

[0070] Embodiment 2:

[0071] As Figures 2 - 5 shown, the difference from the above embodiment is that a digital twin-based municipal engineering water treatment emergency device includes a controller and a filter tank 1. The left and right side walls of the filter tank 1 are respectively connected with an input pipe 2 for water inlet and a connecting pipe 3 for transmitting water flow. A filter plate 6 for filtering pollutants is slidably fitted on the inner wall of the filter tank 1. A sliding groove for the filter plate 6 to slide is opened at the bottom of the filter tank 1, and telescopic plates 17 are symmetrically welded in the sliding groove. The output ends of the telescopic plates 17 are welded to the lower side wall of the filter plate 6. A driving component for driving the filter plate 6 to move is provided at the bottom of the filter plate 6. A purification tank 5 is provided at the bottom of the driving component. A purification component for purifying water resources is provided in the purification tank 5. The lower end of the connecting pipe 3 is communicated with the side wall of the purification tank 5, and an output pipe (not shown in the figure) for draining water is provided on the side wall of the purification tank 5.

[0072] A rubber layer is fixedly bonded to the side wall of the sliding groove, and the rubber layer can improve the sealing performance of the filter tank 1 and prevent the water flow in the filter tank 1 from flowing out.

[0073] As Figure 3 and Figure 4As shown in the figure, the driving component includes a sliding frame 7 bolted to the bottom of the filtering tank 1, and the bottom of the sliding frame 7 is bolted to the top of the purification tank 5; a sliding plate 8 is slidably fitted on the sliding frame 7; the sliding plate 8 is bolted to the bottom of the filter plate 6; a driving member is embedded in the sliding frame 7, and the output shaft of the driving member is bolted to a first eccentric rod 9. A central rod 10 is integrally formed at the bottom of the first eccentric rod 9, and a main gear 11 is bolted and sleeved on the central rod 10; a second eccentric rod 14 is rotatably connected to the bottom of the sliding plate 8, a connecting rod 19 is integrally formed at the bottom of the second eccentric rod 14, and a sub-gear 16 is bolted and sleeved on the connecting rod 19; a hinge rod 12 is rotatably fitted on the connecting rod 19, and the other end of the hinge rod 12 is rotatably fitted with the central rod 10; a moving groove for the first eccentric rod 9 and the second eccentric rod 14 to move is opened at the top of the purification tank 5; the controller is used to control the operation of the driving member, and thus control the rotation of the first eccentric rod 9. In this embodiment, the driving member is a DC motor.

[0074] As Figure 3 shown, the purification component includes a feeding port opened on the side wall of the purification tank 5; stirring rods 13 are bolted to the bottoms of the central rod 10 and the connecting rod 19; a control valve 18 is connected to the communication part between the output pipe and the purification tank 5, and the controller is used to control the opening and closing of the control valve 18, and thus control the drainage of the purification tank 5.

[0075] The specific implementation process is as follows:

[0076] Taking Figure 3 as an example, water flow is introduced into the filtering tank 1 through the input pipe 2, and the water flow will pass through the filter plate 6. The filter plate 6 will intercept the pollutants with larger volume in the water flow, and thus preliminarily purify the water flow.

[0077] During this process, the DC motor is started through the controller. The output shaft of the DC motor will drive the first eccentric rod 9 to rotate. The first eccentric rod 9 will drive the central rod 10 to revolve around the output shaft of the DC motor. Since both the central rod 10 and the connecting rod 19 are hinged to the hinge rod 12, the central rod 10 will drive the connecting rod 19 to move together through the hinge rod 12. During this process, the connecting rod 19 will drive the second eccentric rod 14 to move, and thus the sliding plate 8 will slide along the sliding frame 7, and further the filter plate 6 will slide along the inner wall of the filtering tank 1.

[0078] At the same time, when the central rod 10 revolves, it will also drive the main gear 11 to revolve around the output shaft of the DC motor. Since the connecting rod 19 and the central rod 10 are limited by the hinge rod 12, the main gear 11 and the sub-gear 16 will continuously remain meshed. When the main gear 11 rotates, it will drive the sub-gear 16 to rotate in the opposite direction at the same speed; thus, the second eccentric rod 14 will be driven to rotate, and further drive the filter plate 6 to move, thereby further expanding the moving range of the filter plate 6.

[0079] During this process, the telescopic plates 17 on both sides of the filter plate 6 will expand and contract as the filter plate 6 moves, thereby effectively sealing the filter box 1 and preventing water flow from leaking out. During the movement of the filter plate 6, relative movement will occur between the filter plate 6 and the pollutants, preventing the pollutants from accumulating and blocking the filter plate 6, which would otherwise prevent water flow from passing through; by moving back and forth, the filter plate 6 not only effectively blocks the pollutants but also increases the fluidity of the water flow, thereby improving the filtering effect.

[0080] After the water flow enters the purification tank 5 through the connecting pipe 3, at this time, sewage treatment additives such as acid-base regulators, coagulants, and flocculants are added into the purification tank 5 through the feeding port, and the DC motor is kept running. Driven by the output shaft of the DC motor, the first eccentric rod 9 and the second eccentric rod 14 continue to rotate, and further, the central rod 10 and the connecting rod 19 will also rotate within a large range. The central rod 10 and the connecting rod 19 will drive the stirring rod 13 to stir within a large range, thereby stirring and mixing the water flow and the sewage treatment additives in the purification tank 5 on a large scale, and the water flow can be further purified.

[0081] And during this process, since the main gear 11 and the auxiliary gear 16 will rotate in opposite directions at the same speed, therefore, the first eccentric rod 9 and the second eccentric rod 14 will also rotate in opposite directions at the same speed, causing the central rod 10, the connecting rod 19, and the stirring rod 13 at their bottoms to also rotate in opposite directions at the same speed. As a result, two vortices with different rotation directions will be formed in the water flow in the purification tank 5, colliding with each other, increasing the turbulence of the water flow, improving the stirring and mixing effect of the water flow and the sewage treatment additives, and further enabling the water flow and the sewage treatment additives in the purification tank 5 to be mixed and react more evenly, thereby improving the purification effect of the water flow.

[0082] Embodiment 3:

[0083] As Figure 2 shown, the difference from the above embodiment is that a cleaning port for cleaning pollutants is opened on the side wall of the filter box 1, and a sealing cover plate 15 is hinged to the cleaning port.
