Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for treating domestic sewage. Background Technology

[0002] Chemical companies often have laboratories that research new products or improve existing ones. During these experiments, a large number of chemical reagents are used, which generates wastewater. Because different chemical reagents are used in the experiments, the discharge standards for experimental wastewater and production wastewater are different, so experimental wastewater needs to be treated separately.

[0003] Considering that existing technologies involve adding chemical agents to treat wastewater to render the chemicals used in experiments harmless, this process is not only time-consuming but also generates some byproducts. These byproducts require many steps to treat, and because some existing technologies cannot self-clean, the generation of byproducts may lead to poor purification effects or blockages. After prolonged use, this may result in wastewater treatment failing to meet standards. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater treatment device for treating domestic sewage, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a wastewater treatment device for treating domestic sewage, comprising a sewage treatment shell, a cover plate snapped onto the top of the sewage treatment shell, a clean water tank fixedly installed at the bottom of the sewage treatment shell, an adsorption plate fixedly connected to the middle of the inner wall of the sewage treatment shell, and a purification mechanism fixedly connected to the bottom of the inner wall of the sewage treatment shell; a filtration mechanism snapped onto the top of the purification mechanism; and the outer wall of the filtration mechanism is rotatably connected to the inner wall of the sewage treatment shell.

[0007] The purification mechanism includes a waterproof shell, the bottom of which is fixedly connected to the bottom of the inner wall of the sewage treatment shell. The waterproof shell has an internal cavity, and a drive motor is fixedly connected to the inner wall of the cavity. A drive gear is fixedly connected to the output end of the drive motor. An inner shaft gear meshes with the side of the drive gear away from the drive motor, and an outer shaft gear meshes with the side of the drive gear away from the drive motor. An inner rotating shaft is fixedly connected to the inner wall of the inner shaft gear. An outer rotating shaft is fixedly connected to the top of the outer shaft gear. A filter mechanism is engaged with the top of the inner rotating shaft. Three sets of rotating rods are fixedly connected to the outer wall of the outer rotating shaft. Multiple sets of adsorption blocks are fixedly connected to the outer wall of each set of rotating rods, and the side of each adsorption block facing the same direction of rotation is an inclined plane.

[0008] Using the above technical solution, when sewage enters, the drive motor is started to rotate the rotating rod. The rotation of the rotating rod can drive the adsorption block to rotate synchronously. At the same time as the drive motor is started, electricity is supplied to the adsorption block and the adsorption plate, with the positive and negative terminals respectively. The electricity can create an electrostatic field between the adsorption block and the adsorption plate. When sewage flows through, it will adsorb the ions in it, especially calcium and magnesium. Excessive calcium and magnesium in the water can cause scale to form on metal objects. In the laboratory, after water circulation, the high impurity content in the water can also lead to excessive deviation in experimental results.

[0009] Furthermore, a stirring impeller is snapped into the bottom of the inner rotating shaft; a filter tank is rotatably connected to the bottom of the stirring impeller; a smart water valve is fixedly connected to the inner wall of the sewage treatment shell near the bottom; the outer wall of the stirring impeller is rotatably connected to the inner wall of the smart water valve; a filter element body is snapped into the inner wall of the purified water tank; the outer wall of the filter tank has multiple sets of filter holes, the outer wall of the filter tank is in contact with the inner wall of the filter element body, a support frame is fixedly connected to the bottom of the filter tank, and the bottom of the support frame is fixedly connected to the bottom of the inner wall of the purified water tank.

[0010] By adopting the above technical solution, the intelligent water valve can purify the ionic impurities in the sewage to the discharge standard before it flows in during sewage treatment. After the sewage flows into the filter tank, the filter holes on the filter tank can block smaller impurities to prevent debris from entering the filter element body. The impeller can agitate the sewage and impurities inside to prevent impurities from adhering to the filter holes of the filter tank and preventing the sewage from flowing out. When there are many smaller impurities in the environment, the size of the impeller and the filter tank can be increased to accommodate more impurities.

[0011] Furthermore, the filtration mechanism includes a filter plate, the outer wall of which is engaged with the inner wall of the wastewater treatment shell. The inner wall of the filter plate has multiple sets of through holes. A rotating shaft is rotatably connected to the inner wall of the filter plate, and the inner wall of the filter plate is rotatably connected to the outer wall of the outer rotating shaft. The bottom of the rotating shaft is engaged with the top of the inner rotating shaft. Three sets of cutting impellers are fixedly connected to the outer wall of the rotating shaft. Four sets of stirring rods are fixedly connected to the outer wall of the rotating shaft.

[0012] Using the above technical solution, when sewage enters the equipment, impurities can be filtered through the filter plate. The rotating shaft rotates clockwise, driving the cutting impeller and stirring rod to move clockwise as well. When sewage enters, the water pressure impacts the cutting impeller and assists the rotating shaft in rotating, thereby reducing energy consumption. When the stirring rod rotates, it agitates the water flow and creates a vortex. Since the water pressure at the periphery is higher than the water pressure at the center, impurities will flow towards the center of the filter plate. Even if there are many impurities inside, they will not block all the through holes. Furthermore, since there are no through holes in the center of the filter plate, the flow of impurities towards the center of the filter plate will not affect the filtration efficiency.

[0013] Furthermore, the inner wall of the waterproof shell is provided with a first sealing groove, and there are two sets of the first sealing groove. A first sealing ring is fixedly connected to the inner wall of the first sealing groove. The inner wall of one set of the first sealing rings is rotatably connected to the outer wall of the inner rotating shaft, and the inner wall of the other set of the first sealing rings is rotatably connected to the outer wall of the outer rotating shaft. The inner wall of the filter plate is provided with a second sealing groove, and a second sealing ring is fixedly connected to the inner wall of the second sealing groove. The inner wall of the second sealing ring is rotatably connected to the outer wall of the rotating shaft. The inner wall of the intelligent water valve is provided with a third sealing groove, and a third sealing ring is fixedly connected to the inner wall of the third sealing groove. The inner wall of the third sealing ring is rotatably connected to the outer wall of the stirring impeller.

[0014] By adopting the above technical solution, the first sealing ring can prevent water from flowing into the interior of the waterproof shell, thereby preventing damage to the equipment from water contact; the second sealing ring can prevent water from entering the interior of the waterproof shell through the gap between the inner rotating shaft and the rotating shaft; the third sealing ring can prevent untreated sewage from entering the interior of the filter tank through the gap, thus ensuring the quality of sewage treatment and enabling the sewage treatment to meet the treatment standards.

[0015] Furthermore, each set of through holes is inclined, and the portion of the through hole above the top surface of the filter plate is raised.

[0016] Using the above technical solution, the inclined direction of the through hole is the same as the rotation direction of the rotating shaft. When the stirring rod agitates the water flow and makes the water flow clockwise, it can flow out quickly. When it flows clockwise downwards, it collides with the counterclockwise rotating purification mechanism, which can increase the treatment efficiency of sewage. The inclined protrusion design can prevent impurities from getting stuck in the through hole. Because the height of the through hole is increased, when impurities get stuck in the through hole, they need to lift themselves up first. However, the water flow agitated by the stirring rod will suck away the impurities, thus preventing impurities from clogging the through hole. In addition, the protrusion design can be used for stamping molds or to retain stamping residue. Retaining residue is more economical and does not require additional mold making. However, the sharp edges need to be ground before use to prevent scratches.

[0017] Furthermore, a water inlet is fixedly connected to the top of the cover plate, and the inner wall of the water inlet is provided with threads; a through groove is opened on one side of the water tank, and a water outlet is fixedly connected to the inner wall of the through groove.

[0018] Using the above technical solution, the inlet can be used to discharge sewage into the pipe and connect it with threads. The threads can fix the pipe and increase the sealing, so that the water and gas inside will not flow out from the gaps. The outlet can be used to discharge the treated water. A water pump can be installed inside the water tank and connected to the drain pipe to other equipment for use, storage or direct discharge.

[0019] Furthermore, the rotating rod is flattened and rounded in the direction of rotation, forming an ellipse.

[0020] By adopting the above technical solution, the streamlined shape of the rotating rod can reduce water flow resistance during rotation, thereby reducing energy consumption.

[0021] Furthermore, the edge of the cutting impeller is beveled and has cutting capability.

[0022] By adopting the above technical solution, through the design of the cutting impeller, some larger impurities in the sewage can be cut by the cutting impeller, so that the impurities are smaller when entering the equipment. This avoids excessive accumulation of large impurities that may block the through holes, thereby affecting the sewage treatment efficiency. Furthermore, it can prevent collisions that may occur when the stirring rod agitates the water flow, which could lead to equipment damage. At the same time, it can also prevent large impurities from being unable to flow to the center of the filter plate due to the influence of the water flow.

[0023] Furthermore, the bottom of the cover plate is fixedly connected with a snap-fit ​​block, and there are four sets of snap-fit ​​blocks; the inner wall of the sewage treatment shell is provided with a snap-fit ​​groove, and there are four sets of snap-fit ​​grooves; the inner wall of each set of snap-fit ​​grooves snaps into the outer wall of the snap-fit ​​block.

[0024] By adopting the above technical solution, the snap-fit ​​block and snap-fit ​​slot can be set so that when cleaning is required, the snap-fit ​​block and snap-fit ​​slot can be disengaged by rotating the cover plate, and the top of the equipment can be opened by pulling the cover plate upward. During cleaning, the filter mechanism can be removed as a whole for cleaning, thus ensuring the ease of cleaning.

[0025] The present invention has the following beneficial effects:

[0026] 1. In this invention, when sewage enters, a drive motor is activated to rotate a rotating rod. Simultaneously, the rotating rod drives the adsorption block to rotate synchronously. At the same time as the drive motor is activated, electricity is supplied to the adsorption block and adsorption plate, with the positive and negative terminals respectively. This electricity creates an electrostatic field between the adsorption block and the adsorption plate. When sewage flows through, it adsorbs ions, especially calcium and magnesium. Excessive calcium and magnesium in the water can lead to scale formation on metal objects. In laboratory settings, high impurity content in the water after circulation can also cause significant deviations in experimental results.

[0027] 2. In this invention, when sewage enters the equipment, the filter plate filters impurities. The rotating shaft rotates clockwise, driving the cutting impeller and stirring rod to move clockwise as well. When sewage enters, the water pressure impacts the cutting impeller and assists the rotating shaft, thus reducing energy consumption. The rotating stirring rod agitates the water flow, creating a vortex. Because the water pressure at the perimeter is higher than at the center, impurities flow towards the center of the filter plate. Even with a high concentration of impurities, not all through-holes are blocked. Furthermore, since there are no through-holes in the center of the filter plate, impurities flowing towards the center do not affect the filtration efficiency.

[0028] 3. The inclined direction of the through hole in this invention is the same as the rotation direction of the rotating shaft. When the stirring rod agitates the water flow and makes the water flow clockwise, it can flow out quickly. When the water flows clockwise downwards, it collides with the counterclockwise rotating purification mechanism, which can increase the treatment efficiency of sewage. The inclined protrusion design can prevent impurities from getting stuck in the through hole. The protrusion design can be used for stamping molds or to retain stamping residue. Retaining residue is more economical and does not require additional mold making. However, the sharp edges need to be ground before use to prevent scratches.

[0029] 4. This invention, through the setting of an intelligent water valve, can purify ionic impurities in sewage to the discharge standard before it flows in during sewage treatment. After the sewage flows into the filter tank, the filter holes opened on the filter tank can block smaller impurities to prevent debris from entering the filter element body. The setting of the stirring impeller can agitate the sewage and impurities inside to rotate, so as to prevent impurities from adhering to the filter holes of the filter tank and preventing sewage from flowing out. When there are many smaller impurities in the use environment, the size of the stirring impeller and the filter tank can be increased to accommodate more impurities.

[0030] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0042] The technical solutions of 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.

[0043] Please see Figures 1-8 As shown, the present invention is a sewage treatment device for treating domestic sewage, including a sewage treatment shell 1, a cover plate 11 snapped onto the top of the sewage treatment shell 1, a clean water tank 12 fixedly installed at the bottom of the sewage treatment shell 1, an adsorption plate 18 fixedly connected to the middle of the inner wall of the sewage treatment shell 1, a purification mechanism 2 fixedly connected to the bottom of the inner wall of the sewage treatment shell 1; a filter mechanism 3 snapped onto the top of the purification mechanism 2; and the outer wall of the filter mechanism 3 is rotatably connected to the inner wall of the sewage treatment shell 1.

[0044] The purification mechanism 2 includes a waterproof shell 21. The bottom of the waterproof shell 21 is fixedly connected to the bottom of the inner wall of the sewage treatment shell 1. The interior of the waterproof shell 21 has a cavity, and a drive motor 22 is fixedly connected to the inner wall of the cavity. A drive gear 23 is fixedly connected to the output end of the drive motor 22. An inner shaft gear 24 meshes with the side of the drive gear 23 away from the drive motor 22, and an outer shaft gear 25 meshes with the side of the drive gear 23 away from the drive motor 22. An inner rotating shaft is fixedly connected to the inner wall of the inner shaft gear 24. An outer rotating shaft is fixedly connected to the top of the outer shaft gear 25. A filter mechanism 3 is snapped onto the top of the inner rotating shaft. A rotating rod 26 is fixedly connected to the outer wall of the outer rotating shaft, and there are three sets of rotating rods 26. An adsorption block 27 is fixedly connected to the outer wall of each set of rotating rods 26, and there are multiple sets of adsorption blocks 27. The side of the adsorption block 27 with the same direction of rotation is an inclined surface.

[0045] In this embodiment, in the prior art, chemical agents are added to treat wastewater to render the chemical agents used in the experiment harmless. However, this process is not only time-consuming, but also generates some byproducts. Many steps are still needed to treat the byproducts. Furthermore, since some existing equipment cannot self-clean, the generation of byproducts may lead to poor purification effect or blockage. After long-term use, the wastewater treatment may fail to meet the standards.

[0046] When wastewater enters, the drive motor 22 is activated, causing the drive gear 23 to rotate. This rotation of the drive gear 23 causes the inner shaft gear 24 and the outer shaft gear 25 to rotate in opposite directions. The inner shaft gear 24 drives the inner shaft to rotate clockwise, while the outer shaft gear 25 drives the outer shaft to rotate counter-clockwise. The rotation of the outer shaft causes the rotating rod 26 and the adsorption block 27 to rotate in the same direction. Simultaneously with the activation of the drive motor 22, electricity is supplied to the adsorption block 27 and the adsorption plate 18, which are respectively positive and negative electrodes. This electricity generates an electrostatic field between the adsorption block 27 and the adsorption plate 18, causing charged particles in the wastewater to move towards the oppositely charged electrode. This adsorption effectively adsorbs ions from the wastewater, with particularly good adsorption of calcium and magnesium. The rotation further enhances the electro-adsorption process, resulting in purer wastewater treatment. During ion adsorption, the movement of ions and the resistance of the water to the current cause the water to heat up. This water heating also helps to further improve the absorption of calcium and magnesium. Wastewater undergoes high-temperature sterilization. Because electroadsorption is used for wastewater treatment, it produces the same effect as water electrolysis, electrolyzing water into hydrogen and oxygen. Due to their low density, hydrogen and oxygen rise to the top of the equipment. Ventilation holes can be selectively opened on the top of the cover plate 11 to collect the gas. This gas can be used to fill laboratory consumables. Since hydrogen is a clean energy source and does not pollute the atmosphere when burned, excess hydrogen can be used as laboratory gas for daily use. When cleaning is required, the power to the adsorption block 27 and adsorption plate 18 can be turned off, and clean water can be added inside. Ions adsorbed on the surface of the adsorption block 27 and adsorption plate 18 will fall off due to the loss of the electrostatic field and be washed away by the clean water. The wastewater can be collected during discharge. Because wastewater is cleaned through physical means, no byproducts are produced, and the discharged water can be reused.

[0047] Specifically, an impeller 28 is snapped into the bottom of the inner rotating shaft; a filter tank 29 is rotatably connected to the bottom of the impeller 28; an intelligent water valve 15 is fixedly connected to the inner wall of the sewage treatment shell 1 near the bottom; the outer wall of the impeller 28 is rotatably connected to the inner wall of the intelligent water valve 15; a filter element body 16 is snapped into the inner wall of the water purification tank 12; the outer wall of the filter tank 29 has filter holes, and there are multiple sets of filter holes; the outer wall of the filter tank 29 is in contact with the inner wall of the filter element body 16; a support frame is fixedly connected to the bottom of the filter tank 29; and the bottom of the support frame is fixedly connected to the bottom of the inner wall of the water purification tank 12.

[0048] In this embodiment, it is considered that some smaller solid impurities will enter the equipment, and sewage treatment usually processes a large amount of sewage, and the filter element is usually replaced every few months or half a year. During this period, a large number of impurities in the filter element will cause blockage and affect the filtration efficiency and quality.

[0049] By setting the intelligent water valve 15, the ionic impurities in the sewage can be purified to the discharge standard before flowing in during sewage treatment. After the water flows into the filter tank 29, the filter holes opened on the filter tank 29 can block smaller impurities to prevent debris from entering the filter element body 16, causing the filter element body 16 to become clogged or the filtration effect to deteriorate, thus causing the filtered water to fail to meet the discharge standard. The stirring impeller 28 is engaged with the inner rotating shaft, which can drive the stirring impeller 28 to rotate when the inner rotating shaft rotates. At this time, the stirring impeller 28 will stir the sewage and impurities inside to rotate, preventing impurities from adhering to the filter holes of the filter tank 29 and preventing the sewage from flowing out. When there are many smaller impurities in the environment, the size of the stirring impeller 28 and the filter tank 29 can be increased to accommodate more impurities. Since the size of the stirring impeller 28 and the filter tank 29 is increased, the size of the filter element body 16 will also decrease. Furthermore, due to the more complex environment, the service life of the filter element will be shortened. In this case, in order to ensure that the filtered sewage meets the standards, the replacement time of the filter element needs to be shortened, and the impurities inside the filter tank 29 can be cleaned at the same time as the filter element is replaced.

[0050] Specifically, the filtration mechanism 3 includes a filter plate 31, the outer wall of which is snapped into the inner wall of the sewage treatment housing 1. The inner wall of the filter plate 31 has through holes, and there are multiple sets of through holes. The inner wall of the filter plate 31 is rotatably connected to a rotating shaft 32, and the inner wall of the filter plate 31 is rotatably connected to the outer wall of the outer rotating shaft. The bottom of the rotating shaft 32 is snapped into the top of the inner rotating shaft. The outer wall of the rotating shaft 32 is fixedly connected to a cutting impeller 33, and there are three sets of cutting impellers 33. The outer wall of the rotating shaft 32 is fixedly connected to a stirring rod 34, and there are four sets of stirring rods 34.

[0051] In this embodiment, considering that the sewage may contain solid impurities, larger impurities entering the equipment may collide with the equipment, thereby causing damage to the equipment. Therefore, the sewage needs to be filtered first during sewage treatment. In the prior art, filtration is usually carried out directly using a filter screen, which may cause the filter screen to become clogged during filtration, thereby affecting the sewage treatment efficiency.

[0052] When wastewater enters the equipment, the filter plate 31 filters impurities. The engagement between the rotating shaft 32 and the inner rotating shaft allows the inner rotating shaft to rotate in the same direction as the rotating shaft 32, causing the rotating shaft 32 to rotate clockwise. This clockwise rotation of the rotating shaft 32 drives the cutting impeller 33 and the stirring rod 34 to move clockwise as well. When wastewater enters, the water pressure impacts the cutting impeller 33 and assists the rotating shaft 32 in rotating, thus reducing energy consumption. When the stirring rod 34 rotates, it agitates the water flow and creates a vortex. Since the water pressure at the periphery is higher than at the center, impurities flow towards the center of the filter plate 31. Even if there are many impurities inside, they will not block all the through holes. Furthermore, since there are no through holes in the center of the filter plate 31, the flow of impurities towards the center of the filter plate 31 will not affect the filtration efficiency.

[0053] Specifically, the inner wall of the waterproof shell 21 is provided with a first sealing groove, and there are two sets of the first sealing groove. The inner wall of the first sealing groove is fixedly connected with a first sealing ring. The inner wall of one set of the first sealing rings is rotatably connected to the outer wall of the inner rotating shaft, and the inner wall of the other set of the first sealing rings is rotatably connected to the outer wall of the outer rotating shaft. The inner wall of the filter plate 31 is provided with a second sealing groove, and the inner wall of the second sealing groove is fixedly connected with a second sealing ring. The inner wall of the second sealing ring is rotatably connected to the outer wall of the rotating shaft 32. The inner wall of the intelligent water valve 15 is provided with a third sealing groove, and the inner wall of the third sealing groove is fixedly connected with a third sealing ring. The inner wall of the third sealing ring is rotatably connected to the outer wall of the stirring impeller 28.

[0054] In this embodiment, the first sealing ring prevents water from flowing into the interior of the waterproof shell 21, thus preventing damage to the equipment from water contact; the second sealing ring prevents water from entering the interior of the waterproof shell 21 through the gap between the inner rotating shaft and the rotating shaft 32; and the third sealing ring prevents untreated wastewater from entering the interior of the filter tank 29 through the gap, thus ensuring the quality of wastewater treatment and enabling the wastewater treatment to meet the treatment standards.

[0055] Specifically, each set of through holes is inclined, and the part of the through hole that is higher than the top surface of the filter plate 31 is raised.

[0056] In this embodiment, the tilt direction of the through hole is the same as the rotation direction of the rotating shaft 32. When the stirring rod 34 agitates the water flow and makes the water flow clockwise, it can flow out quickly. When it flows clockwise downwards, it collides with the counterclockwise rotating purification mechanism 2, which can increase the treatment efficiency of sewage. The tilted protrusion design can prevent impurities from getting stuck in the through hole. Since the height of the through hole is increased, when impurities get stuck in the through hole, they need to lift themselves up first. However, the water flow agitated by the stirring rod 34 will suck away the impurities, thereby preventing impurities from blocking the through hole. The protrusion design can be used for stamping molds or to retain stamping residue. Retaining residue is more economical and does not require additional mold making. However, the sharp edges need to be ground before use to prevent scratches.

[0057] Specifically, the top of the cover plate 11 is fixedly connected to a water inlet 13, and the inner wall of the water inlet 13 is provided with threads; a through groove is opened on one side of the water tank 12, and an outlet 14 is fixedly connected to the inner wall of the through groove.

[0058] In this embodiment, the inlet 13 allows sewage to be discharged into a pipe and connected by threads. The threads can fix the pipe and increase the sealing, preventing water and gas from leaking out. The outlet 14 allows the treated water to be discharged. A water pump can be installed inside the clean water tank 12 and connected to a drain pipe to other equipment for use, storage or direct discharge.

[0059] Specifically, the rotating rod 26 is flattened and rounded in the direction of rotation, forming an ellipse.

[0060] In this embodiment, by making it flat and round, the streamlined shape of the rotating rod 26 can reduce the resistance of water flow when it rotates, thereby reducing energy consumption.

[0061] Specifically, the edge of the cutting impeller 33 is beveled and has cutting capability.

[0062] In this embodiment, by designing the cutting impeller 33, some larger impurities in the sewage can be cut by the cutting impeller 33, so that the impurities are smaller when entering the equipment, so as to avoid excessive accumulation of large impurities that block the through holes, thereby affecting the sewage treatment efficiency. Furthermore, collisions may occur when the stirring rod 34 agitates the water flow, which may cause damage to the equipment. At the same time, it can also prevent large impurities from being unable to flow to the center of the filter plate 31 due to the influence of the water flow.

[0063] Specifically, the bottom of the cover plate 11 is fixedly connected with a snap-fit ​​block 17, and there are four sets of snap-fit ​​blocks 17; the inner wall of the sewage treatment shell 1 is provided with a snap-fit ​​groove, and there are four sets of snap-fit ​​grooves; the inner wall of each set of snap-fit ​​grooves snaps into the outer wall of the snap-fit ​​block 17.

[0064] In this embodiment, the snap-fit ​​block 17 and snap-fit ​​groove can be used to directly rotate the cover plate 11 to disengage the snap-fit ​​block 17 and snap-fit ​​groove when cleaning is required, and the top of the device can be opened by pulling up the cover plate 11. The filter mechanism 3 can be removed as a whole for cleaning, thus ensuring the ease of cleaning.

[0065] When using,

[0066] First, when wastewater enters the equipment, the filter plate 31 filters impurities. The engagement between the rotating shaft 32 and the inner rotating shaft allows the inner rotating shaft to rotate in the same direction as the rotating shaft 32. At this time, the rotating shaft 32 will rotate clockwise, driving the cutting impeller 33 and the stirring rod 34 to move clockwise. When wastewater enters, the water pressure will impact the cutting impeller 33 and assist the rotating shaft 32 in rotating, thereby reducing energy consumption. When the stirring rod 34 rotates, it will agitate the water flow and form a vortex. Since the water pressure at the periphery is higher than the water pressure at the center, impurities will flow towards the center of the filter plate 31. Even if there are many impurities inside, they will not block all the through holes. Furthermore, there are no through holes in the center of the filter plate 31, so the flow of impurities towards the center of the filter plate 31 will not affect the filtration efficiency.

[0067] By designing the cutting impeller 33, some larger impurities in the sewage can be cut by the cutting impeller 33, so that the impurities are smaller when entering the equipment, thus avoiding excessive accumulation of large impurities that may block the through holes and affect the sewage treatment efficiency. Furthermore, collisions may occur when the stirring rod 34 agitates the water flow, which may cause damage to the equipment. At the same time, it can also prevent large impurities from being unable to flow to the center of the filter plate 31 due to the influence of the water flow.

[0068] Meanwhile, the tilt direction of the through hole is the same as the rotation direction of the rotating shaft 32. When the stirring rod 34 agitates the water flow and makes the water flow clockwise, it can flow out quickly. When it flows clockwise downwards, it collides with the counterclockwise rotating purification mechanism 2, which can increase the treatment efficiency of sewage. The tilted protrusion design can prevent impurities from getting stuck in the through hole. Because the height of the through hole is increased, when impurities get stuck in the through hole, they need to lift themselves up first. However, the water flow agitated by the stirring rod 34 will suck away the impurities, thus preventing impurities from blocking the through hole. The protrusion design can be used for stamping molds or to retain stamping residue. Retaining residue is more economical and does not require additional mold making. However, the sharp edges need to be ground before use to prevent scratches.

[0069] Secondly, when sewage enters, the drive motor 22 is started, causing the drive gear 23 to rotate. The rotation of the drive gear 23 causes the inner shaft gear 24 and the outer shaft gear 25 to rotate in opposite directions. At this time, the inner shaft gear 24 drives the inner shaft to rotate clockwise, and the outer shaft gear 25 drives the outer shaft to rotate counterclockwise. The rotation of the outer shaft causes the rotating rod 26 and the adsorption block 27 to rotate in the same direction. Simultaneously with starting the drive motor 22, electricity is supplied to the adsorption block 27 and the adsorption plate 18, with the adsorption block 27 and adsorption plate 18 being the positive and negative electrodes, respectively. This electricity generates an electrostatic field between the adsorption block 27 and the adsorption plate 18, causing charged particles in the sewage to move towards the electrode with the opposite charge. This allows for the adsorption of ions in the sewage, particularly calcium and magnesium. The effect is better, and the rotation allows for more complete electroadsorption, resulting in purer wastewater treatment. During ion adsorption, the water temperature rises due to ion movement and the resistance of the water to the current, which can also sterilize the wastewater at high temperatures. Because electroadsorption is used for wastewater treatment, it produces the same effect as water electrolysis, where water is electrolyzed into hydrogen and oxygen. Since hydrogen and oxygen have low densities, they float to the top of the equipment. Ventilation holes can be made at the top of the cover plate 11 to collect the gas. This can not only replenish the consumables needed in the laboratory, but also, since hydrogen is a clean energy source and does not pollute the atmosphere when burned, excess hydrogen can be used as laboratory gas for daily use.

[0070] Then, by setting the intelligent water valve 15, the ionic impurities in the sewage can be purified to the discharge standard before flowing in during sewage treatment. After the water flows into the filter tank 29, the filter holes opened on the filter tank 29 can block smaller impurities to prevent debris from entering the filter element body 16, causing the filter element body 16 to become clogged or the filtration effect to deteriorate, thus causing the filtered water to fail to meet the discharge standard. By engaging the stirring impeller 28 with the inner rotating shaft, the inner rotating shaft can drive the stirring impeller 28 to rotate when it rotates. At this time, the stirring impeller 28 will stir the sewage and impurities inside to rotate, preventing impurities from adhering to the filter holes of the filter tank 29 and preventing the sewage from flowing out. When there are many smaller impurities in the environment, the size of the stirring impeller 28 and the filter tank 29 can be increased to accommodate more impurities. Since the size of the stirring impeller 28 and the filter tank 29 is increased, the size of the filter element body 16 will also decrease. Furthermore, due to the more complex environment, the service life of the filter element will be shortened. At this time, in order to ensure that the filtered sewage meets the standards, the replacement time of the filter element needs to be shortened, and the impurities inside the filter tank 29 can be cleaned at the same time as the filter element is replaced.

[0071] Finally, when cleaning is required, the power to the adsorption block 27 and adsorption plate 18 can be turned off, and clean water can be added inside. At this time, the ions adsorbed on the surface of the adsorption block 27 and adsorption plate 18 will fall off due to the loss of electrostatic field and be washed away from the surface of the adsorption block 27 and adsorption plate 18 by the clean water. They can be collected when discharged. Since the sewage is cleaned by physical means, no by-products are produced, and the discharged water can be reused after cleaning.
