Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an apparatus and method for removing antibiotic resistance genes in wastewater treatment plants. Background Technology

[0002] Antibiotics pose an increasingly serious threat to the ecological environment and human health. Most of them enter the aquatic environment through wastewater discharge, directly polluting water bodies and inducing microorganisms to produce resistance genes, exacerbating antibiotic resistance in the environment. Wastewater treatment plants are dedicated facilities for centralized wastewater treatment. Currently, wastewater treatment plants typically add adsorbent materials to the water to remove antibiotic resistance genes. While this method is easy to operate and highly efficient, the adsorption capacity of the adsorbent materials is limited. After adsorption reaches saturation, the effectiveness in removing antibiotic resistance genes decreases, requiring frequent replacement, which increases operating costs. Furthermore, the adsorbent materials are generally static in the wastewater and cannot fully adsorb antibiotic resistance genes, thus the removal efficiency needs improvement. Therefore, we propose a device and method for removing antibiotic resistance genes in wastewater treatment plants. Summary of the Invention

A transmission frame is provided at the bottom end of the elastic telescopic rod. The end of the transmission frame away from the elastic telescopic rod slides against the top edge of the annular part. The annular part is fixedly provided on the top of the shell and is on the same axis as the elastic telescopic rod. An arc-shaped protrusion is provided on the top of the annular part and on the path of the transmission frame rotating with the elastic telescopic rod, which drives the transmission frame upward.

[0019] A further improvement is that the outer wall of the hollow rotating rod is provided with a groove to accommodate the stirring rod, one end of the stirring rod is rotatably connected to the groove by a torsion spring, the stirring rod is provided with a driving component for driving the stirring rod to rotate into the groove, the outer wall of the hollow rotating rod is provided with a reciprocating thread groove, and the lower end of the outer wall of the hollow rotating rod is fitted with a scraping component for scraping the magnetic convex and concave rod particles adsorbed by the electromagnetic component to move towards the adsorption end of the adsorption tube. The scraping component is driven to move by the reciprocating thread groove of the outer wall of the hollow rotating rod when the stirring rod rotates into the groove.

[0020] A further improvement is that the driving element includes:

[0021] The movable rod is slidably inserted into the hollow rotating rod, and its top end extends to the top of the hollow rotating rod and is rotatably connected to a magnetic component. The bottom of the movable rod is connected to the bottom inner wall of the hollow rotating rod through an elastic connector.

[0023] An annular electromagnetic component, mounted on a support and positioned above a magnetic component, is used to attract the magnetic component when energized. The annular electromagnetic component has an adjustable magnetic force.

[0024] A further improvement is that the scraping element includes:

[0025] A movable block is sleeved on the lower end of the outer wall of the hollow rotating rod. The inner wall of the movable block is provided with an internal thread that mates with the reciprocating thread groove.

The second sensor is electrically connected to a controller and is used to de-energize the electromagnetic component and open the adsorption device when it contacts the connecting frame.

[0031] A method for removing antibiotic resistance genes in wastewater treatment plants, utilizing the aforementioned apparatus, includes the following steps:

[0032] S1: When in use, the water to be treated in the sewage treatment plant enters the shell through the inlet pipe, and then some of the magnetic attapulgite particles in the storage chamber enter the shell to mix with the water. At the same time, the ultraviolet lamp and the stirring mechanism are turned on.

[0033] S2: The stirring mechanism mixes the magnetic attapulgite particles with the water. The magnetic attapulgite particles and ultraviolet lamp equipment remove antibiotic resistance genes in the water. After treatment, the electromagnetic component is turned on to adsorb the magnetic attapulgite particles, and then the treated water is discharged through the outlet pipe.

[0034] In step S2, after the treated water is discharged, the electromagnetic component is turned off and the recycling component is turned on to recycle the magnetic attapulgite particles inside the shell into the processing chamber for processing. After processing, the magnetic attapulgite particles in the processing chamber are discharged into the storage chamber through the connecting pipe for recycling.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1) After removing antibiotic resistance genes in water by combining magnetic attapulgite particles and ultraviolet lamp equipment, the magnetic attapulgite particles inside the shell can be recycled back to the processing chamber for further processing after the treated water is discharged and the electromagnetic device is turned off. This method effectively reduces costs, saves resources, and ensures the removal effect of antibiotic resistance genes in water.

[0037] 2) This invention enables the magnetic attapulgite particles to mix efficiently with water through a hollow rotating rod and a stirring rod, which helps the antibiotic resistance gene pollutants in the wastewater to fully contact the adsorbent material and improve the adsorption efficiency. At the same time, the annular electromagnetic component allows the stirring rod to move vertically during the rotation of the hollow rotating rod, expanding the stirring range of the stirring rod and further improving the removal effect. Furthermore, the magnetic components adsorbed by the annular electromagnetic component can be scraped upwards by a moving scraper, which assists in the recovery of magnetic attapulgite particles and reduces the amount of magnetic attapulgite particles remaining in the shell.

[0038] 3) When the hollow rotating rod rotates, it works with the transmission frame, the ring part and the arc-shaped protrusion to make the elastic telescopic rod rotate and move up and down at the same time. The brush roller and stirring support rod on the outer wall of the elastic telescopic rod can process the magnetic attapulgite particles in the processing chamber and the storage chamber respectively, ensuring the processing quality of the magnetic attapulgite particles in the processing chamber, while preventing the magnetic attapulgite particles in the storage chamber from clumping, and enabling better material discharge.

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.

[0045] Example 1

[0046] Please see the appendix Figure 1 - Appendix Figure 2

[0047] A device for removing antibiotic resistance genes in wastewater treatment plants includes a housing 1. An inlet pipe and an outlet pipe are respectively provided at the upper end and bottom of the outer wall of the housing 1. A valve body can be installed inside both the inlet and outlet pipes.

[0048] Also includes:

[0049] The removal mechanism includes a feeding device located at the top of the shell 1 and several sets of ultraviolet lamp devices 34 embedded in the inner wall of the shell 1; the water entering the shell 1 from the sewage treatment plant is treated by magnetic attapulgite particles and ultraviolet lamp devices 34. The removal of antibiotic resistance genes in water by magnetic attapulgite particles has been disclosed in the prior art, for example, in publication number: CN214734668U, and will not be described in detail here. The ultraviolet lamp device 34 is prior art, and the removal of antibiotic resistance genes in water by it has been disclosed in the prior art, for example, in publication number: CN117417070B, and will not be described in detail here.

[0050] The feeding equipment includes a processing shell 2 and a partition 20 integrated inside the processing shell 2, which divides the processing shell 2 into a processing chamber and a storage chamber from top to bottom.

[0051] The storage chamber contains magnetic attapulgite particles for removing antibiotic resistance genes, and the storage chamber is connected to the shell 1 through a pipe. A valve can be installed in the pipe. By opening the valve, the magnetic attapulgite particles in the storage chamber can enter the shell 1. A port connected to the storage chamber is also opened on one side of the processing shell 2. A sealing door is provided at the port so that the magnetic attapulgite particles can be replaced by opening the sealing door after a period of use.

[0052] The storage chamber and the processing chamber are interconnected by a connecting pipe provided on the partition 20. A valve body is also provided inside the connecting pipe. Figure 2 As shown, the separator 20 is inclined, with its right end higher than its left end, and the connecting pipe can be set at the left end of the separator 20.

[0053] The processing chamber is equipped with a recycling processing component. The input end of the recycling processing component is connected to the housing 1 and is used to recycle the magnetic attapulgite particles in the housing 1 into the processing chamber for processing.

[0054] Electromagnetic component 18, for example, a single-sided electromagnetic plate, has magnetic ends on its inner surface, and is disposed on the inner walls of both sides of the housing 1. It is used to attract magnetic attapulgite particles when energized. The electromagnetic component 18 is energized with magnetic poles opposite to those of the magnetic attapulgite particles; and...

[0055] The stirring mechanism is located inside the housing 1.

[0056] To ensure the effectiveness of the magnetic attapulgite particles in removing antibiotic resistance genes during recycling, the preferred embodiment of this embodiment includes the following recycling process:

[0057] Heating device 22 is embedded in the inner wall of the processing chamber. Heating device 22 is a conventional device in this field and will not be described in detail here.

[0058] The liquid supply pipe 23 has one end connected to the processing chamber and the other end connected to the output end of the device (not shown in the figure) that supplies washing liquid;

[0059] The drain pipe 24, one end of which is connected to the processing chamber, also includes a filter structure. This filter structure can be a filter screen with a mesh diameter smaller than that of the magnetic attapulgite particles, used to separate the washing liquid from the magnetic attapulgite particles. The drain pipe 24 can be located on the left side of the processing housing 2 and correspond to the left end of the separator 20; and...

[0060] The adsorption device 21, for example, is a pump body, which is located on the processing shell 2. Its input end is connected to two sets of adsorption tubes, and the adsorption ends of the two sets of adsorption tubes penetrate through the top of the shell 1 and extend to the top of the two electromagnetic components 18 respectively. The output end of the adsorption device 21 is connected to the processing chamber.

[0061] After draining the water from the shell 1, the electromagnetic component 18 can be turned off and the adsorption device 21 can be turned on. The adsorption device 21 will extract the magnetic attapulgite particles from the shell 1 into the processing chamber. Then, the magnetic attapulgite particles will be heated and regenerated by turning on the heating device 22. After heating, the washing liquid supply device will supply the washing liquid into the processing chamber through the liquid supply pipe 23 to wash the magnetic attapulgite particles. Then, the washing liquid will be discharged through the drain pipe 24. The heating device 22 will be turned on again to heat and dry the magnetic attapulgite particles. After drying, the magnetic attapulgite particles in the processing chamber will be discharged into the storage chamber through the connecting pipe.

[0062] It should be noted that the processing chamber can also be connected to a device for inputting inert gas (such as nitrogen). When heating the magnetic attapulgite particles, inert gas can be input for protection.

[0063] The above methods can be used to process used magnetic attapulgite particles, restoring their adsorption properties and extending their service life for reuse.

[0064] Please see the appendix Figure 3 - Appendix Figure 4

[0065] Preferably, the stirring mechanism in this embodiment includes:

[0066] A hollow rotating rod 3 is vertically rotatable within the housing 1 via bearings, and its top end extends above the top of the housing 1 and is fitted with a driven gear 12. Several sets of stirring rods 6 are provided on the outer wall of the hollow rotating rod 3, and the stirring rods 6 are located within the housing 1; and...

[0067] The rotating device 11, such as a motor, is mounted on the top of the housing 1 via an L-shaped bracket, and the output end of the rotating device 11 is provided with a driving gear that meshes with the driven gear 12.

[0068] The rotating device 11 drives the driving gear, which in turn drives the driven gear 12 to rotate the hollow rotating rod 3. The hollow rotating rod 3 then mixes the water and magnetic attapulgite particles through the stirring rod 6.

[0069] Preferably, in this embodiment, a vertically rotatable elastic telescopic rod 25 is provided inside the processing shell 2. One end of the elastic telescopic rod 25 is rotatably connected to the inner wall of the top of the processing cavity via a bearing, and the other end movably passes through the bottom of the processing shell 2 and is fitted with a driven gear 26 that meshes with the driven gear 12. When the driven gear 12 rotates, it drives the elastic telescopic rod 25 to rotate through the driven gear 26. The axial height of the driven gear 12 is less than the axial height of the driven gear 26 to ensure that when the elastic telescopic rod 25 extends and retracts to move the driven gear 26, the driven gear 26 can always remain meshed with the driven gear 12. The fixed section of the elastic telescopic rod 25 is located on the outer wall of the processing chamber and is equipped with several sets of brush rollers 27. The fixed section of the elastic telescopic rod 25 is located on the outer wall of the storage chamber and is equipped with several sets of stirring rods. The stirring rods can be made of rubber material. The bottom end of the elastic telescopic rod 25 is equipped with a transmission frame 29. The transmission frame 29 is L-shaped. The end of the transmission frame 29 away from the elastic telescopic rod 25 slides against the top edge of the annular part 28. The annular part 28 is fixed on the top of the housing 1 and is on the same axis as the elastic telescopic rod 25. The top of the annular part 28 and located on the path of the transmission frame 29 rotating with the elastic telescopic rod 25 is equipped with an arc-shaped protrusion 30 that drives the transmission frame 29 upward.

[0070] When the hollow rotating rod 3 rotates, it simultaneously drives the driven gear 26 via the driven gear 12, which in turn causes the elastic telescopic rod 25 to rotate. The elastic telescopic rod 25 drives the transmission frame 29 to move in a circular motion along the top of the annular part 28. During its movement, the transmission frame 29 intermittently moves to the arc-shaped protrusion 30, which causes the elastic telescopic rod 25 to retract upward. When the transmission frame 29 and the arc-shaped protrusion 30 are misaligned, the elastic telescopic rod 25 returns to its original position downward. In this way, the brush roller 27 and the stirring support rod on the outer wall of the fixed section of the elastic telescopic rod 25 can move up and down while the elastic telescopic rod 25 rotates. The brush roller 27 efficiently rubs the magnetic attapulgite particles in the treatment chamber, which facilitates better heating and washing of the magnetic attapulgite particles in the treatment chamber. The stirring support rod facilitates better discharge of the magnetic attapulgite particles in the storage chamber.

[0071] Preferably, in this embodiment, the outer wall of the hollow rotating rod 3 is provided with a groove 5 to accommodate the stirring rod 6. One end of the stirring rod 6 is rotatably connected to the groove 5 by a torsion spring. The stirring rod 6 is provided with a driving component for driving the stirring rod 6 to rotate into the groove 5. The outer wall of the hollow rotating rod 3 is provided with a reciprocating threaded groove. The lower end of the outer wall of the hollow rotating rod 3 is provided with a scraping component for scraping the magnetic embossed particles adsorbed by the electromagnetic component 18 to move towards the adsorption end of the adsorption tube. The scraping component is driven to move by the reciprocating threaded groove of the outer wall of the hollow rotating rod 3 when the stirring rod 6 rotates into the groove 5.

[0072] Preferably, the driving component in this embodiment includes:

[0073] The movable rod 4 is slidably inserted into the hollow rotating rod 3. For example, the movable rod 4 can be slidably connected to the vertical groove on the inner wall of the hollow rotating rod 3 via a slider, so that the movable rod 4 can move up and down relative to the hollow rotating rod 3 and rotate with the hollow rotating rod 3. Its top end extends to the top of the hollow rotating rod 3 and is rotatably connected to a magnetic element 8 via a bearing. The bottom of the movable rod 4 is connected to the bottom inner wall of the hollow rotating rod 3 via an elastic connector 17, which is, for example, an elastic telescopic rod.

[0074] A pull rope 7 has one end connected to the outer end of the stirring rod 6, and the other end movably passes through the corresponding groove 5 and is connected to the movable rod 4. A roller can be installed on the inner wall of the groove 5 to guide the pull rope 7. When the movable rod 4 moves upward, it pulls the pull rope 7, causing the corresponding stirring rod 6 to rotate into the groove 5. When the movable rod 4 moves downward, the stirring rod 6 returns to its original position under the action of a torsion spring.

[0075] An annular electromagnetic component 9, mounted on a support and positioned above the magnetic component 8, is used to attract the magnetic component 8 when energized. The annular electromagnetic component 9 has an adjustable magnetic force structure. For example, the annular electromagnetic component 9 includes an electromagnetic ring and a sliding resistor connected to the electromagnetic ring. The current in the circuit is adjusted by the sliding resistor, thereby controlling the magnetic force of the electromagnet. Of course, the annular electromagnetic component 9 is not limited to the above structure. When the magnetic force of the annular electromagnetic component 9 is at its maximum, the annular electromagnetic component 9 attracts and contacts the magnetic component 8, thereby causing the stirring rod 6 to rotate into the groove 5. By adjusting the magnetic force of the annular electromagnetic component 9, the magnetic component 8 can also drive the movable rod 4 to move up and down, thereby controlling the stirring rod 6 to swing back and forth within the housing 1, thereby expanding the stirring range of the stirring rod 6 and enhancing the mixing effect of the magnetic attapulgite particles and water.

[0076] Preferably, the scraping element in this embodiment includes:

[0077] The movable block 13 is sleeved on the lower end of the outer wall of the hollow rotating rod 3. The inner wall of the movable block 13 is provided with an internal thread that mates with the reciprocating thread groove so that the movable block 13 can move up and down when the hollow rotating rod 3 rotates. The outer circumference of the movable block 13 is provided with several sets of slots.

[0078] The connecting frame 14 is movably sleeved on the outside of the movable block 13. The inner wall of the connecting frame 14 is embedded with several sets of telescopic locking blocks 16 that can enter the slots. The telescopic locking blocks 16 include, for example, an electric telescopic rod and a locking block provided at the end of the electric telescopic rod.

[0079] Two sets of scraper blades 15 are provided, respectively located on both sides of the connecting frame 14. One side of the scraper blade 15 is in contact with the magnetic end of the electromagnetic component 18.

[0080] The sliding frame 19 has one end connected to the connecting frame 14 and the other end slidably connected to the slide rail on the inner wall of the housing 1, which is used to restrict the connecting frame 14 to move only up and down and not rotate; and;

[0081] Sensor 10 is mounted on a bracket, with its detection end extending below the annular electromagnetic component 9. Sensor 10 is electrically connected to controller 31, which controls the telescopic card block 16 to enter the card slot when the annular electromagnetic component 9 contacts the magnetic component 8.

[0082] When the annular electromagnetic component 9 is not energized, the telescopic block 16 does not enter the slot. At this time, the rotation of the hollow rotating rod 3 will only drive the moving block 13 to rotate. When the magnetic force of the annular electromagnetic component 9 is at its maximum, the stirring rod 6 rotates into the groove 5. And because the annular electromagnetic component 9 contacts the magnetic component 8, the controller 31 controls the telescopic block 16 to enter the slot. Because the connecting frame 14 is limited by the sliding connection with the inner wall of the housing 1, when the hollow rotating rod 3 rotates, the moving block 13 drives the connecting frame 14 to move from bottom to top through the cooperation of the internal thread and the reciprocating thread groove. When moving, the magnetic convex and concave rod particles adsorbed by the magnetic end of the electromagnetic component 18 are scraped upward by the scraper 15.

[0083] Preferably, in this embodiment, the top inner wall of the housing 1 is connected to a sensor 33 via an elastic connector 32. The elastic connector 32 is, for example, an elastic telescopic rod. The sensor 33 is electrically connected to the controller 31 and is used to de-energize the electromagnetic component 18 and open the adsorption device 21 when it contacts the connecting frame 14.

[0084] When the connecting frame 14 is upward, it first contacts the sensor 2 33, and then the electromagnetic component 18 is de-energized, and the adsorption device 21 is opened. At this time, the scraped magnetic attapulgite particles fall onto the scraper 15. Since the scraper 15 is close to the adsorption end of the adsorption tube, the magnetic attapulgite particles on the scraper 15 are sucked out and detached from the scraper 15. In this way, the magnetic attapulgite particles are efficiently recycled, and the magnetic attapulgite particles remaining in the shell 1 are reduced.

[0085] A method for removing antibiotic resistance genes in wastewater treatment plants, utilizing the aforementioned apparatus, includes the following steps:

[0086] S1: When in use, the water to be treated in the sewage treatment plant enters the shell 1 through the inlet pipe, and then some of the magnetic attapulgite particles in the storage chamber enter the shell 1 to mix with the water. At the same time, the ultraviolet lamp device 34 and the stirring mechanism are turned on.

[0087] S2: The stirring mechanism mixes the magnetic attapulgite particles with the water. The magnetic attapulgite particles and the ultraviolet lamp device 34 remove the antibiotic resistance genes in the water. After treatment, the electromagnetic component 18 is turned on to adsorb the magnetic attapulgite particles, and then the treated water is discharged through the outlet pipe.

[0088] In step S2, after the treated water is discharged, the electromagnetic component 18 is turned off and the recycling component is turned on to recycle the magnetic attapulgite particles in the shell 1 into the processing chamber for processing. After processing, the magnetic attapulgite particles in the processing chamber are discharged into the storage chamber through the connecting pipe for recycling.

[0089] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
