Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a high-efficiency wastewater treatment device and treatment process. Background Technology

[0002] In biofilm wastewater treatment processes, packing devices are typically installed in the wastewater treatment tank to treat the wastewater.

[0003] According to patent application CN116969580A, a wastewater treatment tank packing device and process are disclosed. This scheme uses suspension ropes and connecting ropes to suspend multiple packing balls. Since the multiple packing balls are evenly distributed, the packing balls and packing material can be lifted together by the suspension ropes and connecting ropes when the treatment tank is under maintenance. Its structure is simple and reasonable, convenient to use, and saves time and effort. Because the multiple packing balls are evenly distributed by the connecting ropes, the packing balls inside the wastewater treatment tank are evenly distributed, resulting in high biochemical treatment efficiency of wastewater or sewage. The cavity formed by the two counterweight shells is filled with counterweight blocks to prevent the suspended packing balls from swaying too much under the action of water. The packing partition plates that are equally divided on the outer walls of the two counterweight shells can equally divide the inner cavity formed by the two storage shells, so that the packing material inside the packing balls is equally divided, further improving the efficiency of wastewater or sewage biochemical treatment.

[0004] While the wastewater treatment tank, when used in conjunction with the above-mentioned solutions, can treat the wastewater within, it has certain drawbacks. For example, because there is no restraint on the bottom packing balls, they are prone to swaying under the influence of water flow. This can cause adjacent packing balls on the same horizontal plane to become entangled, deviating from their proper positions and affecting the effectiveness of the wastewater treatment tank. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art: In existing sewage treatment ponds, adjacent packing balls on the same horizontal plane below are prone to getting tangled together, which affects the effectiveness of the sewage treatment pond.

[0006] A high-efficiency wastewater treatment device and treatment process are proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions: A high-efficiency wastewater treatment device includes a wastewater treatment tank. Multiple mounting frames are arranged within the wastewater treatment tank. Multiple packing assemblies are vertically arranged within each mounting frame. Each packing assembly includes multiple assembly units, with adjacent assembly units fixedly connected. Each assembly unit includes a lower mounting column, an upper mounting column, a packing ball, and a connector. The packing ball is positioned between the lower and upper mounting columns. The connector is used for the fixed connection between the lower and upper mounting columns. The lower mounting column, located at the bottom, is rotatably mounted inside the mounting frame. A rotating column is fixed to the upper end of the upper mounting column, with the upper end of the rotating column rotatably penetrating the mounting frame. A drive assembly is provided on the wastewater treatment tank to cooperate with the rotation of the packing assemblies.

[0008] As a further technical solution of the present invention, each of the connectors includes two lower connecting plates fixed to the outer surface of the lower mounting column, and two upper connecting plates symmetrically fixed to the outer surface of the upper mounting column. A receiving column is fixed to the upper end of the lower connecting plate, and a threaded column is fixed to the upper end of the receiving column. A through hole for use with the threaded column is opened on the upper connecting plate, and a locking nut is threaded to the upper end of the threaded column.

[0009] As a further technical solution of the present invention, a lower abutment block is fixed on the upper end face of the lower mounting column, an upper abutment block is fixed on the lower end face of the upper mounting column, and a packing ball is disposed between the lower abutment block and the upper abutment block.

[0010] As a further technical solution of the present invention, the driving component includes a movable seat movably disposed above the sewage treatment tank. A plurality of lower T-shaped plates are fixed on the lower end face of the movable seat. A rack plate is fixed on one side of the lower T-shaped plates. A gear that cooperates with the rack plate is fixedly sleeved on the upper end of each rotating column.

[0011] As a further technical solution of the present invention, electric tracks are fixed on both sides of the sewage treatment tank, and an electric slider is slidably arranged in each electric track, with the moving seat fixed to the upper end face of the electric slider.

[0012] As a further technical solution of the present invention, the inner wall of the sewage treatment tank is provided with multiple pairs of side slots 1 for use with the mounting frame, and the inner wall of the sewage treatment tank is also provided with a pair of side slots 2. A filter frame is movably arranged between the two side slots 2, a filter layer is fixed on the inner wall of the filter frame, and a control unit is arranged between the movable seat and the filter frame.

[0013] As a further technical solution of the present invention, the control unit includes an upper plate fixed to the upper surface of the movable seat, a connecting rope fixed between the upper plate and the upper surface of the filter frame, a U-shaped frame fixed to the upper surface of the sewage treatment tank, a fixed pulley group for use with the connecting rope fixed on the side wall of the U-shaped frame, and a reinforcing rib plate for use with the upper plate fixed to the upper surface of the movable seat.

[0014] As a further technical solution of the present invention, a scraper is rotatably arranged on the inner wall of the sewage treatment tank, a stepper motor for use with the scraper is arranged on the outer wall of the sewage treatment tank, a receiving frame is movably arranged on the inner wall of the sewage treatment tank, a collection frame is placed in the receiving frame, and two side baffles are symmetrically fixed on the upper surface of the scraper.

[0015] As a further technical solution of the present invention, two side grooves are symmetrically opened on the inner wall of the sewage treatment tank, and a movable block is movably arranged in each side groove, and the receiving frame is fixed between the two movable blocks.

[0016] A high-efficiency wastewater treatment process, applied to the aforementioned high-efficiency wastewater treatment device, comprises the following steps: Step 1: Place the installation frame containing multiple packing components into the sewage treatment tank, and use the packing balls to purify the sewage in the sewage treatment tank. Step 2: When the biofilm on the surface of the packing balls needs to be detached, the driving component can drive each packing component to rotate, thereby causing each packing ball to rotate rapidly, increasing the shear force between the water flow and the biofilm on the surface of the packing balls, and assisting in the detachment of the biofilm.

[0017] The beneficial effects of this invention are: 1. In use, the lower mounting column at the bottom is rotatably positioned at the inner bottom of the mounting frame, and the upper end of the upper mounting column at the top is fixed with a rotating column that rotates through the mounting frame. Furthermore, adjacent assembly units are fixedly connected, resulting in the packing assembly formed by the assembly units remaining vertical during use. The lower mounting column, upper mounting column, packing balls, and connectors will not be displaced by the water flow during use, preventing the packing balls at the bottom from tangling. When the biofilm on the surface of the packing balls needs to be detached, the driving component can drive each packing assembly to rotate, causing each packing ball to rotate rapidly. This increases the shear force between the water flow and the biofilm on the surface of the packing balls, thus assisting in biofilm detachment.

[0018] 2. During assembly, first place the packing ball to be used on the upper end of the lower mounting column. Then, through the through hole, the two upper connecting plates can be fitted onto the threaded column. During this process, continue until the lower end face of the upper connecting plate contacts the upper surface of the receiving column. The receiving column supports and limits the weight of the upper connecting plate and the upper mounting column. At this time, the upper mounting column abuts against the upper surface of the packing ball, and the packing ball is clamped between the lower and upper mounting columns. Then, tighten the lock nut onto the threaded column to complete the assembly connection of the upper connecting plates. When it is necessary to replace the corresponding packing ball, simply unscrew the corresponding lock nut, lift the corresponding upper mounting column upward, remove the original packing ball, and replace it with a new packing ball. The operation is convenient.

[0019] 3. In the initial state, the filter frame does not contact the sewage in the wastewater treatment tank. Before the packing balls need to rotate, the moving seat moves towards the filter frame. Under the action of the control unit, the filter frame and filter layer move downwards. When the filter frame and filter layer move to the designated position, the moving seat and rack plate are about to contact the gear. Then the moving seat continues to move towards the filter frame. At this time, the rack plate drives the gear to rotate, causing each packing ball to rotate and demold. The filter layer intercepts the biofilm in the sewage. After the filter layer has intercepted the biofilm for a period of time, the moving seat moves away from the filter frame. When the moving seat and rack plate are just disengaged from the gear, the filter frame and filter layer move upwards. When the moving seat continues to move away from the filter frame, it pulls the filter frame, filter layer and intercepted biofilm out of the water surface for easy subsequent cleaning.

[0020] 4. In the initial state, the scraper is positioned above the receiving frame and does not contact the filter layer to avoid affecting the downward movement of the filter frame and filter layer. After the filter frame and filter layer complete the interception of biofilm and move upward to the water surface, the scraper rotates towards the filter layer under the action of the stepper motor until the end of the scraper adheres to the surface of the filter layer. Then, the filter frame and filter layer move downward again. During this process, the scraper scrapes off the biofilm intercepted on the surface of the filter layer. Under the action of gravity, the biofilm slides down the surface of the scraper into the collection frame. After the filter frame and filter layer complete the transfer of biofilm, the filter frame and filter layer move upward again away from the water surface. During this process, the stepper motor causes the scraper to rotate away from the filter layer. During this process, the side baffle rotates with the scraper until the side baffle collides with the upper surface of the receiving frame, causing the scraper to vibrate and helping the biofilm adhering to the working surface of the scraper to fall into the collection frame.

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0024] Reference Figures 1-12 A high-efficiency sewage treatment device includes a sewage treatment tank 1, which is existing technology. Multiple mounting frames 2 are installed inside the sewage treatment tank 1. Multiple packing assemblies are vertically installed within each mounting frame 2. Each packing assembly includes multiple assembly units, which are fixedly connected to adjacent assembly units. Each assembly unit includes a lower mounting column 3, an upper mounting column 4, a packing ball 7, and a connector. The packing ball 7 is located between the lower mounting column 3 and the upper mounting column 4, which is existing technology. The connector is used for the fixed connection between the lower mounting column 3 and the upper mounting column 4. The lower mounting column 3, located at the bottommost point, is rotatably mounted inside the mounting frame 2, allowing for a rotatable connection between the lower mounting column 3 and the mounting frame 2, which is existing technology. A rotating column 12 is fixed to the upper end of the uppermost mounting column 4, and the upper end of the rotating column 12 rotatably penetrates the mounting frame 2. A drive assembly is installed on the sewage treatment tank 1 to cooperate with the rotation of the packing assemblies.

[0025] In use, the lower mounting column 3, located at the bottom, is rotatably positioned at the inner bottom of the mounting frame 2. A rotating column 12 is fixed to the upper end of the upper mounting column 4, with the upper end of the rotating column 12 rotatably penetrating the mounting frame 2. Furthermore, adjacent assembly units are fixedly connected, resulting in the packing assembly formed by the assembly units remaining vertical during use. The lower mounting column 3, upper mounting column 4, packing balls 7, and connectors will not be displaced by water flow during use, preventing the packing balls 7 from becoming entangled. When the biofilm on the surface of the packing balls 7 needs to be detached, the driving component can drive each packing assembly to rotate, causing each packing ball 7 to rotate rapidly. This increases the shear force between the water flow and the biofilm on the surface of the packing balls 7, thus assisting in biofilm detachment.

[0026] Reference Figures 1-6 Each connector includes two lower connecting plates 8 fixed to the outer surface of the lower mounting column 3, and two upper connecting plates 9 symmetrically fixed to the outer surface of the upper mounting column 4. A receiving column 34 is fixed to the upper end of the lower connecting plate 8, and a threaded column 10 is fixed to the upper end of the receiving column 34. A through hole for use with the threaded column 10 is opened on the upper connecting plate 9. A locking nut 11 is threaded to the upper end of the threaded column 10. The diameter of the threaded column 10 is smaller than the diameter of the receiving column 34.

[0027] During assembly, the packing ball 7 to be used is first placed on the upper end of the lower mounting column 3. Then, through the through hole, the two upper connecting plates 9 can be fitted onto the threaded column 10. During this process, the lower end face of the upper connecting plate 9 contacts the upper surface of the receiving column 34. The receiving column 34 supports and limits the weight of the upper connecting plate 9 and the upper mounting column 4. At this time, the upper mounting column 4 abuts against the upper surface of the packing ball 7, and the packing ball 7 is clamped between the lower mounting column 3 and the upper mounting column 4. Then, the locking nut 11 is tightened onto the threaded column 10 to complete the assembly connection of the upper connecting plate 9 and the upper mounting column 4. When it is necessary to replace the corresponding packing ball 7, simply unscrew the corresponding locking nut 11, lift the corresponding upper mounting column 4 upwards, remove the original packing ball 7, and replace it with a new packing ball 7. The operation is convenient.

[0028] Reference Figure 3 and Figure 5 The lower mounting column 3 has a lower abutment block 5 fixed on its upper end face, and the upper mounting column 4 has an upper abutment block 6 fixed on its lower end face. The packing ball 7 is disposed between the lower abutment block 5 and the upper abutment block 6. The packing ball 7 has a certain elasticity. After the packing ball 7 is clamped between the lower abutment block 5 and the upper abutment block 6, it will undergo elastic deformation within a reasonable range.

[0029] When placing the packing ball 7, the packing ball 7 can also be clamped between the lower contact block 5 and the upper contact block 6 by the cooperation of the set lower contact block 5 and the upper contact block 6, thereby increasing the distance between the packing ball 7 and the lower contact block 5 and the upper contact block 6, and improving the biofilm formation effect on the surface of the packing ball 7.

[0030] Reference Figure 1 , Figure 2 and Figure 7 The drive assembly includes a movable seat 13 movably mounted above the sewage treatment tank 1. Multiple lower T-shaped plates 14 are fixed to the lower end face of the movable seat 13. A rack plate 15 is fixed to one side of the lower T-shaped plate 14. A gear 16 that works with the rack plate 15 is fixedly sleeved on the upper end of each rotating column 12.

[0031] During the movement of the movable seat 13, it will drive the lower T-shaped plate 14 and the rack plate 15 to move together. When the rack plate 15 contacts the gear 16, the movable seat 13 continues to move. Through the cooperation of the rack plate 15 and the gear 16, the rotating column 12 and the uppermost mounting column 4 can be driven to rotate. Thus, under the action of the upper connecting plate 9, the threaded column 10, the receiving column 34, and the lower connecting plate 8, the entire packing assembly is driven to rotate, thereby assisting in the demolding of the biofilm.

[0032] Reference Figure 1 and Figure 2Both sides of the sewage treatment tank 1 are fixed with electric rails 17, and each electric rail 17 is slidably equipped with an electric slider 18. The moving seat 13 is fixed to the upper end face of the electric slider 18.

[0033] The electric track 17 and the electric slider 18 are existing technologies, as is the translation of the movable seat 13.

[0034] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The inner wall of the sewage treatment tank 1 has multiple pairs of side slots 19 for use with the mounting frame 2. The inner wall of the sewage treatment tank 1 also has a pair of side slots 20. A filter frame 21 is movably arranged between the two side slots 20. A filter layer 22 is fixed on the inner wall of the filter frame 21. A control unit is arranged between the movable seat 13 and the filter frame 21. The filter layer 22 is only used to intercept the biofilm that falls off in the sewage.

[0035] In the initial state, the filter frame 21 does not contact the sewage in the sewage treatment tank 1. Before the packing balls 7 need to rotate, the moving seat 13 moves towards the filter frame 21. Under the action of the control unit, the filter frame 21 and the filter layer 22 move downward. When the filter frame 21 and the filter layer 22 move downward to the designated position, the moving seat 13 and the rack plate 15 are about to contact the gear 16. Then the moving seat 13 continues to move towards the filter frame 21. At this time, the rack plate 15 drives the gear 16 to rotate, causing each packing ball 7 to rotate and be demolded. The biofilm in the sewage is intercepted by the filter layer 22. After the filter layer 22 has intercepted for a period of time, the moving seat 13 moves away from the filter frame 21. When the moving seat 13 and the rack plate 15 just disengage from the gear 16, the filter frame 21 and the filter layer 22 move upward. When the moving seat 13 continues to move away from the filter frame 21, the filter frame 21, the filter layer 22 and the intercepted biofilm are pulled out of the water surface, making it convenient for subsequent cleaning.

[0036] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The control unit includes an upper plate 23 fixed to the upper surface of the movable seat 13. A connecting rope 24 is fixed between the upper plate 23 and the upper surface of the filter frame 21. A U-shaped frame 25 is fixed to the upper surface of the sewage treatment tank 1. A fixed pulley group 26 for use with the connecting rope 24 is fixed on the side wall of the U-shaped frame 25. A reinforcing rib plate 27 for use with the upper plate 23 is fixed to the upper surface of the movable seat 13.

[0037] The fixed pulley group 26 and the connecting rope 24 work together to enable the movable seat 13 to control the lifting and lowering displacement of the filter frame 21.

[0038] Reference Figures 1-2 and Figures 9-12 A scraper 28 is rotatably installed on the inner wall of the sewage treatment tank 1. A stepper motor 35 is installed on the outer wall of the sewage treatment tank 1 to cooperate with the scraper 28. A receiving frame 29 is movably installed on the inner wall of the sewage treatment tank 1. A collection frame 30 is placed inside the receiving frame 29. Two side baffles 31 are symmetrically fixed on the upper surface of the scraper 28. The scraper 28, the receiving frame 29 and the collection frame 30 are all above the water surface.

[0039] Initially, the scraper 28 is positioned above the receiving frame 29, not in contact with the filter layer 22, to avoid affecting the downward movement of the filter frame 21 and the filter layer 22. After the filter frame 21 and the filter layer 22 have completed their biofilm interception and moved above the water surface, the scraper 28, under the action of the stepper motor 35, rotates towards the filter layer 22 until its end adheres to the surface of the filter layer 22. Then, the filter frame 21 and the filter layer 22 move downwards again. During this process, the scraper 28 scrapes off the biofilm intercepted on the surface of the filter layer 22. Under the influence of gravity, the biofilm slides down the surface of the scraper 28 into the collection frame 30. After the filter frame 21 and filter layer 22 have completed the transfer of biofilm, the filter frame 21 and filter layer 22 move upward again away from the water surface. During this process, the stepper motor 35 causes the scraper 28 to rotate away from the filter layer 22. During this process, the side baffle 31 rotates with the scraper 28 until the side baffle 31 collides with the upper surface of the receiving frame 29, causing the scraper 28 to vibrate and helping the biofilm adhering to the working surface of the scraper 28 to fall into the collection frame 30.

[0040] Reference Figure 8 , Figure 9 , Figure 10 and Figure 12 Two side grooves 32 are symmetrically opened on the inner wall of the sewage treatment tank 1. A movable block 33 is movably arranged in each side groove 32, and the receiving frame 29 is fixed between the two movable blocks 33.

[0041] There is a certain friction between the movable block 33 and the side groove 32 to prevent the receiving frame 29 and the movable block 33 from shifting during normal operation.

[0042] A high-efficiency wastewater treatment process, applied to the aforementioned high-efficiency wastewater treatment device, comprises the following steps: Step 1: Place the installation frame 2, which is equipped with multiple packing components, into the sewage treatment tank 1, and use the packing balls 7 to purify the sewage in the sewage treatment tank 1. Step 2: When the biofilm on the surface of the packing ball 7 needs to be detached, the driving component can drive each packing component to rotate, thereby causing each packing ball 7 to rotate rapidly, which increases the shear force between the water flow and the biofilm on the surface of the packing ball 7, and assists in the detachment of the biofilm.

[0043] When in use, the lower mounting column 3 is rotatably mounted on the inner bottom of the mounting frame 2, and the upper end of the upper mounting column 4 is fixed with a rotating column 12. The upper end of the rotating column 12 rotates through the mounting frame 2, and the adjacent assembly units are fixedly connected. As a result, the packing assembly formed by the assembly units is in a vertical state during use. The lower mounting column 3, upper mounting column 4, packing ball 7 and connectors will not be displaced by the water flow during use. This prevents the packing ball 7 at the bottom from getting tangled. When the biofilm on the surface of the packing ball 7 needs to be detached, the driving component can drive each packing assembly to rotate, thereby causing each packing ball 7 to rotate rapidly. This increases the shear force between the water flow and the biofilm on the surface of the packing ball 7, thus assisting in the detachment of the biofilm. During assembly, the packing ball 7 to be used is first placed on the upper end of the lower mounting column 3. Then, through the through hole, the two upper connecting plates 9 can be fitted onto the threaded column 10. During this process, the lower end face of the upper connecting plate 9 contacts the upper surface of the receiving column 34. The receiving column 34 supports and limits the weight of the upper connecting plate 9 and the upper mounting column 4. At this time, the upper mounting column 4 abuts against the upper surface of the packing ball 7, and the packing ball 7 is clamped between the lower mounting column 3 and the upper mounting column 4. Then, the locking nut 11 is tightened onto the threaded column 10 to complete the assembly connection of the upper connecting plate 9 and the upper connecting plate 4. When it is necessary to replace the corresponding packing ball 7, simply unscrew the corresponding locking nut 11, lift the corresponding upper mounting column 4 upward, remove the original packing ball 7, and replace it with a new packing ball 7. The operation is convenient. During the movement of the movable seat 13, it will drive the lower T-shaped plate 14 and the rack plate 15 to move together. When the rack plate 15 contacts the gear 16, the movable seat 13 continues to move. Through the cooperation of the rack plate 15 and the gear 16, the rotating column 12 and the uppermost mounting column 4 can be driven to rotate. Thus, under the action of the upper connecting plate 9, the threaded column 10, the receiving column 34, and the lower connecting plate 8, the entire packing assembly is driven to rotate, thereby assisting in the demolding of the biofilm. In the initial state, the filter frame 21 does not contact the sewage in the sewage treatment tank 1. Before the packing balls 7 need to rotate, the moving seat 13 moves towards the filter frame 21. Under the action of the control unit, the filter frame 21 and the filter layer 22 are moved down. When the filter frame 21 and the filter layer 22 move down to the designated position, the moving seat 13 and the rack plate 15 are about to contact the gear 16. Then the moving seat 13 continues to move towards the filter frame 21. At this time, the rack plate 15 drives the gear 16 to rotate, causing each packing ball 7 to rotate and be demolded. The biofilm in the sewage is intercepted by the filter layer 22. After the filter layer 22 has intercepted for a period of time, the moving seat 13 moves away from the filter frame 21. When the moving seat 13 and the rack plate 15 are just disengaged from the gear 16, the filter frame 21 and the filter layer 22 move upward. When the moving seat 13 continues to move away from the filter frame 21, the filter frame 21, the filter layer 22 and the intercepted biofilm are pulled out of the water surface, making it convenient for subsequent cleaning. Initially, the scraper 28 is positioned above the receiving frame 29, not in contact with the filter layer 22, to avoid affecting the downward movement of the filter frame 21 and the filter layer 22. After the filter frame 21 and the filter layer 22 have completed their biofilm interception and moved above the water surface, the scraper 28, under the action of the stepper motor 35, rotates towards the filter layer 22 until its end adheres to the surface of the filter layer 22. Then, the filter frame 21 and the filter layer 22 move downwards again. During this process, the scraper 28 scrapes off the biofilm intercepted on the surface of the filter layer 22. Under the influence of gravity, the biofilm slides down the surface of the scraper 28 into the collection frame 30. After the filter frame 21 and filter layer 22 have completed the transfer of biofilm, the filter frame 21 and filter layer 22 move upward again away from the water surface. During this process, the stepper motor 35 causes the scraper 28 to rotate away from the filter layer 22. During this process, the side baffle 31 rotates with the scraper 28 until the side baffle 31 collides with the upper surface of the receiving frame 29, causing the scraper 28 to vibrate and helping the biofilm adhering to the working surface of the scraper 28 to fall into the collection frame 30.
