Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a device for treating concentrated water after membrane separation. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a certain water body or reuse. By treating wastewater, pollutants discharged into natural water bodies can be reduced, water pollution can be prevented, the ecological balance of rivers, lakes, oceans and other water bodies can be protected, the living environment of aquatic organisms can be maintained, and the sustainable use of water resources can be guaranteed. Many industries such as chemical industry, printing and dyeing, papermaking, etc. require a large amount of water resources, and at the same time, a large amount of sewage will be generated. Effective sewage treatment can realize the recycling of water resources, reduce the water cost of enterprises, improve the utilization efficiency of water resources, and promote the sustainable development of industrial production; in addition, a good water environment can also attract investment and promote the development of industries such as tourism. In recent years, with the gradual maturity of membrane separation technology and the decline in cost, it has been widely used in the treatment of water and wastewater. In the sewage treatment process, the concentrated water after membrane separation needs to be treated again.

[0003] At present, in the conventional treatment of concentrated water, as the concentrated water is stirred, the particulate impurities are suspended, which makes it inconvenient to remove the particulate impurities in the concentrated water. As a result, the concentrated water is still mixed with a large amount of particulate impurities, resulting in an inadequate sewage treatment effect. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A device for treating concentrated water after membrane separation, comprising a treatment tank, a liquid inlet assembly is installed at the side of the top of the treatment tank, and a liquid discharge pipe is installed in the middle of the bottom of the treatment tank;

[0006] A stirring mechanism, which is used to mix the reagent in the treatment tank and the concentrated water after membrane separation, and the stirring mechanism is installed in the middle of the treatment tank;

[0007] The stirring mechanism includes a rotating shaft and a servo motor, wherein the rotating shaft is rotatably installed in the middle of the inside of the treatment tank, the servo motor is fixedly installed in the middle of the top of the treatment tank, the output end of the servo motor is fixedly installed with the top of the rotating shaft through a coupling, a defoaming component is installed on the outer cylindrical surface of the rotating shaft near the top position of the inner cavity of the treatment tank, and a stirring plate is fixedly connected to the outer cylindrical surface of the rotating shaft near the bottom position of the inner cavity of the treatment tank, and a circular arc hole is opened on the surface of the stirring plate. The rotating shaft is driven to rotate by the rotation of the output end of the servo motor and the fixed installation of the coupling, so that the stirring plate is driven to rotate together with the rotating shaft. As the stirring plate rotates continuously, the reagent in the treatment tank and the concentrated water after membrane separation can be mixed, which is helpful for treating the concentrated water;

[0008] An impurity removal mechanism, which is used to process impurities in concentrated water after membrane separation, and is installed in the middle of the inner cavity of the treatment tank;

[0009] Wherein, the impurity removal mechanism includes a conical filter and a collecting assembly, the edge of the bottom of the conical filter is fixedly connected to the middle of the inner wall of the processing tank, the outer cylindrical surface of the rotating shaft is rotatably installed between the top of the conical filter, and the collecting assembly is installed in the middle of the outer cylindrical surface of the processing tank, a lower conical extension ring is fixedly connected to the middle of the surface of the conical filter, an upper conical extension ring is fixedly connected to the surface of the conical filter and near the top, guide plates are fixedly installed on the surfaces of the lower conical extension ring and the upper conical extension ring, and a toggle tooth is fixedly installed in the middle of the surface of the upper conical extension ring. By injecting concentrated water into the interior of the processing tank and allowing the concentrated water to pass through the conical filter, particulate impurities in the concentrated water can be filtered, thereby performing preliminary treatment on the impurities in the concentrated water, and combined with the gradual reduction of the inner diameter of the conical filter from bottom to top, the filtered impurities will be deposited downward and close to the inner wall of the processing tank, which is helpful for the subsequent removal of impurities.

[0010] Preferably, the stirring plate is installed at an angle, and there are three stirring plates, and the three stirring plates are evenly installed along the circumferential direction of the axis of the rotating shaft. As the stirring plate rotates continuously, and combined with the inclined installation of the stirring plate, the concentrated water at the bottom of the inner cavity of the treatment tank can be flipped upward when the stirring plate rotates, which is helpful for the full fusion of the concentrated water and the reagent. In addition, the arc hole is opened on the surface of the stirring plate, and when the stirring plate rotates, the contact area between the stirring plate and the concentrated water can be reduced, thereby reducing the resistance and helping the stirring plate to rotate smoothly.

[0011] Preferably, the defoaming component includes a connecting sleeve and a base tooth. The center of the connecting sleeve is fixedly connected to the outer cylindrical surface of the rotating shaft and close to the top position of the inner cavity of the treatment tank. The base tooth is fixedly connected to the outer cylindrical surface of the rotating shaft and close to the connecting sleeve. A supporting spring bar is fixedly connected to the middle of the outer cylindrical surface of the connecting sleeve and close to the toggle tooth. A semicircular force block is fixedly connected to the end of the supporting spring bar away from the connecting sleeve.

[0012] Preferably, the supporting elastic bars are installed just above the base teeth, there are three supporting elastic bars, and the three supporting elastic bars are evenly distributed in the middle of the outer circumferential surface of the connecting sleeve.

[0013] Preferably, the axis at the center of the conical filter coincides with the axis of the rotating shaft, the guide vanes are arc-shaped, and the guide vanes are evenly distributed on the surfaces of the lower conical extension ring and the upper conical extension ring. The concentrated water in the treatment tank is stirred by a stirring plate to rotate the concentrated water in the treatment tank, so that the impurities in the concentrated water are affected by centrifugal force, and combined with the guiding effect of the guide vanes, the impurities in the concentrated water are moved to a position close to the inner wall of the treatment tank, thereby making full use of the movement of the concentrated water and combining with the centrifugal force to promote the aggregation of impurities.

[0014] Preferably, the upper conical extension ring is installed directly above the lower conical extension ring, the toggle teeth are arc-shaped, there are three toggle teeth, and the three toggle teeth are evenly distributed in the middle of the surface of the upper conical extension ring. As the impurities in the concentrated water are affected by the centrifugal force, they move toward the inner wall of the treatment tank and extend outward in combination with the lower conical extension ring and the upper conical extension ring, the backflow of the aggregated particulate impurities is reduced, making it difficult for the aggregated impurities to float at will.

[0015] Preferably, the collecting assembly comprises a crescent-shaped square tube, the crescent-shaped square tube is fixedly connected to the outer circumferential surface of the processing tank and is close to the bottom of the conical filter screen, the liquid inlet and the liquid outlet of the crescent-shaped square tube are both connected to the processing tank, a sealing cover is sealedly installed at the middle of the top of the crescent-shaped square tube, a conical bucket is fixedly installed in the inner cavity of the crescent-shaped square tube and is close to the liquid inlet, a flat plate is fixedly installed at the top of the inner cavity of the crescent-shaped square tube and is close to the conical bucket, and the inner cavity of the crescent-shaped square tube and is close to the liquid outlet A slag screen is fixedly installed. When the stirring plate stirs the concentrated water in the treatment tank, the concentrated water is caused to rotate in a circle. Under the action of centrifugal force, the filtered particulate impurities can be driven to rotate along the inner wall of the treatment tank, so that the particulate impurities enter from the liquid inlet of the crescent-shaped square tube and pass through the conical bucket. They can be intercepted by the slag screen, thereby filtering and removing the particulate impurities. The filtered concentrated water returns to the treatment tank from the liquid outlet of the crescent-shaped square tube, thus forming a cycle and fully treating the particulate impurities.

[0016] Preferably, the flat plate is installed at an angle, and the position of the flat plate corresponds to the position of the conical bucket. As the concentrated water carries the particulate impurities through the conical bucket and under the flow of the concentrated water fluid, combined with the inclined installation of the flat plate, the particulate impurities are not easy to flow back, which can effectively reduce the backflow of particulate impurities.

[0017] As the rotating shaft drives the defoaming assembly to rotate as a whole, the supporting spring bar will rotate with the rotating shaft under the connection of the connecting sleeve. The supporting spring bar will contact the toggle tooth so that the supporting spring bar is pushed upward by the toggle tooth, which can make the supporting spring bar elastically deform. The semicircular force-bearing block will move upward with the elastic deformation of the supporting spring bar. As the supporting spring bar continues to rotate, the supporting spring bar will be separated from the toggle tooth, and the upward force on the supporting spring bar will disappear. The elastic force of the supporting spring bar itself can be used to move the semicircular force-bearing block downward for reset, so that the concentrated water surface in the treatment tank can be struck to generate vibration, so that the bubbles floating on the concentrated water surface will burst, thereby achieving defoaming and making full use of the interaction between the structures to connect the structures together.

[0018] Preferably, the liquid inlet component includes a right-angle pipe and a right-angle frame, the bottom end of the right-angle pipe is fixedly installed at the top of the treatment tank and close to the servo motor, and the right-angle pipe is connected to the treatment tank, the top of the right-angle frame is fixedly connected to the top of the inner cavity of the treatment tank and close to the rotating shaft, a valve is installed in the middle of the surface of the right-angle pipe, and a cone is rotatably installed at the bottom end of the right-angle frame and close to the liquid outlet of the right-angle pipe, and an impeller blade is fixedly connected to the conical surface of the cone surface. The concentrated water to be treated is injected from the right-angle pipe so that the concentrated water flows downward from the bottom end of the right-angle pipe, and the flow of the concentrated water can be used to impact the impeller blade, so that the cone and the impeller blade rotate together, so that the rotation of the impeller blade can be used to sprinkle the concentrated water flowing downward, so that the concentrated water is sprinkled evenly and the accumulation of particulate impurities carried by the concentrated water is reduced.

[0019] Preferably, the cone is installed directly below the liquid outlet of the right-angle pipe, and the impeller blades are evenly distributed on the conical surface of the cone.

[0020] The present invention provides a device for treating concentrated water after membrane separation. It has the following beneficial effects:

[0021] 1. The treatment equipment for concentrated water after membrane separation utilizes the rotation of the output end of the servo motor and the fixed installation of the coupling to drive the rotating shaft to rotate, so that the stirring plate is driven by the rotating shaft to rotate together. As the stirring plate rotates continuously, the reagent in the treatment tank and the concentrated water after membrane separation can be mixed, which is helpful for treating the concentrated water.

[0022] Second, the treatment equipment for concentrated water after membrane separation, as the stirring plate rotates continuously and is installed at an angle, the concentrated water at the bottom of the inner cavity of the treatment tank can be flipped upward when the stirring plate rotates, which is helpful for the full fusion of the concentrated water and the reagent. In addition, the circular arc hole is opened on the surface of the stirring plate. When the stirring plate rotates, the contact area between the stirring plate and the concentrated water can be reduced, thereby reducing the resistance and helping the stirring plate to rotate smoothly.

[0023] 3. The treatment equipment for concentrated water after membrane separation uses concentrated water to be injected into the interior of the treatment tank, so that the concentrated water passes through the conical filter to filter the particulate impurities in the concentrated water, thereby performing preliminary treatment on the impurities in the concentrated water. Combined with the conical filter, the inner diameter gradually decreases from bottom to top, so that the filtered impurities will be deposited downward and close to the inner wall of the treatment tank, which is helpful for the subsequent removal of impurities.

[0024] Fourth, the treatment equipment for concentrated water after membrane separation uses a stirring plate to stir the concentrated water in the treatment tank, so that the concentrated water in the treatment tank rotates, so that the impurities in the concentrated water are affected by centrifugal force, and combined with the guiding effect of the guide plate, the impurities in the concentrated water move to a position close to the inner wall of the treatment tank, making full use of the movement of concentrated water and combining with centrifugal force to promote the aggregation of impurities.

[0025] 5. The treatment equipment for concentrated water after membrane separation, as the impurities in the concentrated water are moved toward the inner wall of the treatment tank under the action of centrifugal force, and combined with the lower conical extension ring and the upper conical extension ring extending outward, reduces the backflow of the aggregated particulate impurities, making it difficult for the aggregated impurities to float at will.

[0026] 6. The treatment equipment for concentrated water after membrane separation, when the stirring plate stirs the concentrated water in the treatment tank, makes the concentrated water rotate in a circle, and under the action of centrifugal force, the filtered particulate impurities can be driven to rotate along the inner wall of the treatment tank, so that the particulate impurities enter from the liquid inlet of the crescent-shaped square tube, pass through the conical bucket, and can be intercepted by the slag net, so that the particulate impurities are filtered and removed, and the filtered concentrated water returns to the treatment tank from the liquid outlet of the crescent-shaped square tube again, thus forming a cycle, and the particulate impurities are fully treated.

[0027] 7. The treatment equipment for concentrated water after membrane separation, as the concentrated water carries particulate impurities through the conical bucket, and under the flow of concentrated water fluid, combined with the inclined installation of the flat plate, the particulate impurities are not easy to flow back, which can effectively reduce the backflow of particulate impurities.

[0028] 8. The treatment equipment for concentrated water after membrane separation, under the connection of the connecting sleeve, uses the rotating shaft to drive the supporting spring bar to rotate, so that the supporting spring bar is pushed upward by the toggle tooth, which can make the supporting spring bar elastically deform, and the semicircular force-bearing block will move upward with the elastic deformation of the supporting spring bar. As the supporting spring bar is separated from the toggle tooth, the upward force on the supporting spring bar disappears, and the elastic force of the supporting spring bar itself can be used to move the semicircular force-bearing block downward for reset, so that the concentrated water surface in the treatment tank can be struck to generate vibration, so that the bubbles floating on the concentrated water surface are broken, thereby achieving defoaming.

[0029] 9. The treatment equipment for concentrated water after membrane separation injects the concentrated water to be treated from the right-angle pipe, so that the concentrated water flows downward from the bottom of the right-angle pipe. The flow of concentrated water can be used to impact the impeller blades, so that the cone and the impeller blades rotate together. The rotation of the impeller blades can be used to spread the concentrated water flowing downward, so that the concentrated water is spread evenly and the accumulation of particulate impurities carried by the concentrated water is reduced.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0043] A device for treating concentrated water after membrane separation, comprising a treatment tank 1, a liquid inlet assembly 2 is installed at the side of the top of the treatment tank 1, and a liquid discharge pipe 3 is installed in the middle of the bottom of the treatment tank 1;

[0044] A stirring mechanism 4, which is used to mix the reagent in the treatment tank 1 and the concentrated water after membrane separation, and the stirring mechanism 4 is installed in the middle of the treatment tank 1;

[0045] The stirring mechanism 4 includes a rotating shaft 41 and a servo motor 42. The rotating shaft 41 is rotatably installed in the middle of the inside of the treatment tank 1. The servo motor 42 is fixedly installed in the middle of the top of the treatment tank 1. The output end of the servo motor 42 is fixedly installed with the top of the rotating shaft 41 through a coupling. A defoaming component 43 is installed on the outer cylindrical surface of the rotating shaft 41 and near the top position of the inner cavity of the treatment tank 1. A stirring plate 44 is fixedly connected to the outer cylindrical surface of the rotating shaft 41 and near the bottom position of the inner cavity of the treatment tank 1. The surface of the stirring plate 44 is provided with an arc hole 45. The staff turns on the servo motor 42 to work, and uses the rotation of the output end of the servo motor 42 and the fixed installation of the coupling to drive the rotating shaft 41 to rotate, so that the stirring plate 44 is driven by the rotating shaft 41 to rotate together. As the stirring plate 44 rotates continuously, the reagents in the treatment tank 1 and the concentrated water after membrane separation can be mixed;

[0046] The stirring plates 44 are installed at an angle. There are three stirring plates 44, and the three stirring plates 44 are evenly installed along the circumferential direction of the axis of the rotating shaft 41. As the stirring plates 44 rotate continuously, and combined with the inclined installation of the stirring plates 44, the concentrated water at the bottom of the inner cavity of the treatment tank 1 can be flipped upward when the stirring plates 44 rotate, which is helpful for the complete fusion of the concentrated water and the reagent. In addition, the arc hole 45 is opened on the surface of the stirring plate 44. When the stirring plate 44 rotates, the contact area between the stirring plate 44 and the concentrated water can be reduced, thereby reducing the resistance and helping the stirring plate 44 to rotate smoothly.

[0047] The second embodiment is based on the first embodiment. Figures 1 to 9 As shown:

[0048] The impurity removal mechanism 5 is used to process impurities in the concentrated water after membrane separation, and the impurity removal mechanism 5 is installed in the middle of the inner cavity of the treatment tank 1;

[0049] The impurity removal mechanism 5 includes a conical filter 51 and a collecting assembly 52. ​​The edge of the bottom of the conical filter 51 is fixedly connected to the middle of the inner wall of the treatment tank 1. The outer cylindrical surface of the rotating shaft 41 is rotatably installed between the top of the conical filter 51. The collecting assembly 52 is installed in the middle of the outer cylindrical surface of the treatment tank 1. A lower conical extension ring 53 is fixedly connected to the middle of the surface of the conical filter 51. An upper conical extension ring 54 is fixedly connected to the surface of the conical filter 51 and near the top. Guide plates 55 are fixedly installed on the surfaces of the lower conical extension ring 53 and the upper conical extension ring 54. A toggle tooth 56 is fixedly installed in the middle of the surface of the upper conical extension ring 54. By injecting concentrated water into the interior of the treatment tank 1, the concentrated water passes through the conical filter 51, so that the particulate impurities in the concentrated water can be filtered, thereby preliminarily treating the impurities in the concentrated water. In combination with the gradual reduction of the inner diameter of the conical filter 51 from bottom to top, the filtered impurities will be deposited downward and close to the inner wall of the treatment tank 1.

[0050] The axis at the center of the conical filter screen 51 coincides with the axis of the rotating shaft 41 . The guide vanes 55 are arc-shaped and are evenly distributed on the surfaces of the lower conical extension ring 53 and the upper conical extension ring 54 .

[0051] The concentrated water in the treatment tank 1 is stirred by the stirring plate 44 to rotate the concentrated water in the treatment tank 1, so that the impurities in the concentrated water are affected by the centrifugal force. Combined with the guiding effect of the guide plate 55, the impurities in the concentrated water are moved to a position close to the inner wall of the treatment tank 1, thereby making full use of the movement of the concentrated water and combining with the centrifugal force to promote the aggregation of impurities.

[0052] The upper conical extension ring 54 is installed directly above the lower conical extension ring 53. The toggle teeth 56 are arc-shaped. There are three toggle teeth 56, and the three toggle teeth 56 are evenly distributed in the middle of the surface of the upper conical extension ring 54. As the impurities in the concentrated water are acted upon by the centrifugal force, they move toward the inner wall of the treatment tank 1 and extend outward in combination with the lower conical extension ring 53 and the upper conical extension ring 54, thereby reducing the random floating of the aggregated particulate impurities.

[0053] The collecting assembly 52 includes a crescent-shaped square tube 521, which is fixedly connected to the outer circumferential surface of the processing tank 1 and close to the bottom of the conical filter 51. The liquid inlet and the liquid outlet of the crescent-shaped square tube 521 are both connected to the processing tank 1. A sealing cover 522 is sealedly installed in the middle of the top of the crescent-shaped square tube 521. A conical bucket 523 is fixedly installed in the inner cavity of the crescent-shaped square tube 521 and close to the liquid inlet. A flat plate 524 is fixedly installed at the top of the inner cavity of the crescent-shaped square tube 521 and close to the conical bucket 523. The inner cavity of the crescent-shaped square tube 521 and close to the liquid outlet are fixedly installed with a flat plate 524. A slag blocking net 525 is fixedly installed. When the stirring plate 44 stirs the concentrated water in the treatment tank 1, the concentrated water is caused to rotate in a circle. Under the action of centrifugal force, the filtered particulate impurities can be driven to rotate along the inner wall of the treatment tank 1, so that the particulate impurities enter from the liquid inlet of the crescent-shaped square tube 521 and pass through the conical bucket 523. They can be intercepted by the slag blocking net 525, thereby filtering and removing the particulate impurities. The filtered concentrated water returns to the treatment tank 1 from the liquid outlet of the crescent-shaped square tube 521, thus forming a cycle and fully treating the particulate impurities.

[0054] The flat plate 524 is installed at an angle, and the position of the flat plate 524 corresponds to the position of the conical bucket 523. As the concentrated water carries the particulate impurities through the conical bucket 523 and under the flow of the concentrated water fluid, combined with the inclined installation of the flat plate 524, the particulate impurities are not easy to flow back, which can effectively reduce the backflow of particulate impurities.

[0055] The defoaming component 43 includes a connecting sleeve 431 and a base tooth 434. The center of the connecting sleeve 431 is fixedly connected to the outer cylindrical surface of the rotating shaft 41 and close to the top position of the inner cavity of the processing tank 1. The base tooth 434 is fixedly connected to the outer cylindrical surface of the rotating shaft 41 and close to the connecting sleeve 431. The middle of the outer cylindrical surface of the connecting sleeve 431 and close to the toggle tooth 56 is fixedly connected with a supporting spring bar 432. The end of the supporting spring bar 432 away from the connecting sleeve 431 is fixedly connected with a semicircular force block 433. As the rotating shaft 41 drives the defoaming component 43 to rotate as a whole, under the connection of the connecting sleeve 431, the supporting spring bar 432 will rotate with the rotating shaft 41. , by utilizing the contact between the support spring bar 432 and the toggle tooth 56, the support spring bar 432 is pushed upward by the toggle tooth 56, so that the support spring bar 432 can be elastically deformed, and the semicircular force-bearing block 433 will move upward with the elastic deformation of the support spring bar 432. As the support spring bar 432 continues to rotate, the support spring bar 432 is separated from the toggle tooth 56, and the upward force on the support spring bar 432 disappears. The elastic force of the support spring bar 432 itself can be used to move the semicircular force-bearing block 433 downward for reset, so that the concentrated water surface in the treatment tank 1 can be struck to generate vibration, so that the bubbles floating on the concentrated water surface are burst.

[0056] The supporting spring bars 432 are installed just above the base teeth 434 . There are three supporting spring bars 432 , and the three supporting spring bars 432 are evenly distributed in the middle of the outer circumferential surface of the connecting sleeve 431 .

[0057] The third embodiment is based on the first and second embodiments. Figures 1 to 10 As shown:

[0058] The liquid inlet component 2 includes a right-angle pipe 21 and a right-angle frame 22. The bottom end of the right-angle pipe 21 is fixedly installed at the top of the treatment tank 1 and close to the servo motor 42, and the right-angle pipe 21 is connected to the treatment tank 1. The top of the right-angle frame 22 is fixedly connected to the top of the inner cavity of the treatment tank 1 and close to the rotating shaft 41. A valve 23 is installed in the middle of the surface of the right-angle pipe 21. A cone 24 is rotatably installed at the bottom end of the right-angle frame 22 and close to the liquid outlet of the right-angle pipe 21. An impeller blade 25 is fixedly connected to the conical surface of the cone 24. The staff injects the concentrated water to be treated from the right-angle pipe 21, so that the concentrated water flows downward from the bottom end of the right-angle pipe 21, and the flow of the concentrated water can be used to impact the impeller blade 25, so that the cone 24 and the impeller blade 25 rotate together, so that the rotation of the impeller blade 25 can be used to sprinkle the concentrated water flowing downward, so that the concentrated water is sprinkled evenly and the accumulation of particulate impurities carried by the concentrated water is reduced.

[0059] The cone 24 is installed just below the liquid outlet of the right-angle pipe 21 , and the impeller blades 25 are evenly distributed on the conical surface of the cone 24 .

[0060] When in use, the staff first injects the concentrated water to be treated from the right-angle pipe 21, so that the concentrated water flows downward from the bottom end of the right-angle pipe 21, and then the flow of the concentrated water can be used to impact the impeller blade 25, so that the cone 24 and the impeller blade 25 rotate together, so that the rotation of the impeller blade 25 can be used to spread the concentrated water flowing downward, so that the concentrated water is spread evenly, and the sewage treatment agent is added from the pipe opening on the side of the top of the treatment tank 1, so that the concentrated water contacts the agent;

[0061] The concentrated water is injected into the processing tank 1, and the concentrated water passes through the conical filter 51, so that the particulate impurities in the concentrated water can be filtered, thereby preliminarily treating the impurities in the concentrated water. In combination with the conical filter 51, the inner diameter gradually decreases from bottom to top, so that the filtered impurities are deposited downward and close to the inner wall of the processing tank 1.

[0062] At the same time, the staff starts the servo motor 42 to work, and uses the rotation of the output end of the servo motor 42 and the fixed installation of the coupling to drive the rotating shaft 41 to rotate, so that the stirring plate 44 is driven by the rotating shaft 41 to rotate together. As the stirring plate 44 rotates continuously, the reagent in the treatment tank 1 and the concentrated water after membrane separation can be mixed;

[0063] As the stirring plate 44 rotates continuously, and the stirring plate 44 is installed at an angle, the stirring plate 44 can flip the concentrated water at the bottom of the inner cavity of the treatment tank 1 upward when it rotates, which helps to fully blend the concentrated water and the reagent. In addition, the circular arc hole 45 is opened on the surface of the stirring plate 44. When the stirring plate 44 rotates, the contact area between the stirring plate 44 and the concentrated water can be reduced, thereby reducing resistance and helping the stirring plate 44 to rotate smoothly.

[0064] The concentrated water in the treatment tank 1 is stirred by the stirring plate 44, so that the concentrated water in the treatment tank 1 rotates, so that the impurities in the concentrated water are subjected to the centrifugal force, and combined with the guide effect of the guide plate 55, the impurities in the concentrated water move to a position close to the inner wall of the treatment tank 1, making full use of the movement of the concentrated water and combining with the centrifugal force to promote the aggregation of impurities;

[0065] The impurities in the concentrated water are moved toward the inner wall of the treatment tank 1 by the centrifugal force, and the lower conical extension ring 53 and the upper conical extension ring 54 extend outward, thereby reducing the random floating of the aggregated granular impurities.

[0066] When the stirring plate 44 stirs the concentrated water in the treatment tank 1, the concentrated water is caused to rotate in a circle, and under the action of centrifugal force, the filtered particulate impurities can be driven to rotate along the inner wall of the treatment tank 1, so that the particulate impurities enter from the liquid inlet of the crescent-shaped square tube 521 and pass through the conical bucket 523, and can be intercepted by the slag net 525, so that the particulate impurities are filtered and removed, and the filtered concentrated water returns to the treatment tank 1 from the liquid outlet of the crescent-shaped square tube 521 again, thus forming a cycle, and the particulate impurities are fully treated.

[0067] At the same time, as the concentrated water carries the particulate impurities through the conical bucket 523, and under the flow of the concentrated water fluid, combined with the inclined installation of the flat plate 524, the particulate impurities are not easy to flow back, which can effectively reduce the backflow of particulate impurities.

[0068] The spring bar 432 is then pushed upward by the tooth 56 to move the spring bar 432 upwards, and the spring bar 432 is then pushed back by the tooth 56 to move the spring bar 432 upwards.

[0069] When the concentrated water treatment is completed, the liquid can be discharged from the drain pipe 3, and the blocking cover 522 is opened to take out the particle impurities filtered out of the crescent-shaped square tube 521.
