Abstract
Description
Technical Field
[0001] This invention relates to the field of pharmaceutical wastewater treatment technology, specifically to an anaerobic, targeted biological treatment device for hormone-based pharmaceutical wastewater. Background Technology
[0002] Hormone-based pharmaceutical wastewater is characterized by its complex composition, high concentration of organic matter, and strong toxicity. Anaerobic targeted biological treatment equipment is an effective treatment device developed specifically to address these characteristics. The anaerobic reactor is the core equipment that utilizes anaerobic microorganisms to decompose organic pollutants in an anaerobic environment.
[0003] Essential equipment in an anaerobic reactor includes riser pipes and downcomers. The riser pipes drive the treated wastewater upwards, while the downcomers guide the liquid after gas-liquid separation back to the bottom of the reactor to maintain the sludge concentration at the bottom and reduce sludge loss. However, in actual use, the flow rate of the return liquid is difficult to control. If the flow rate is too fast, it can easily wash away the sludge bed at the bottom of the reactor. If the flow rate is too slow, the circulation effect will be poor and sludge will easily accumulate. Long-term use can easily cause blockage inside the downcomer, requiring regular cleaning. In addition, the pipe body is relatively long, resulting in high installation costs and difficulties. Summary of the Invention
[0004] The technical problem of the present invention is to provide an anaerobic directional acclimation biological treatment device for hormone pharmaceutical wastewater, which uses a limiting component as a buffer and a water guiding component to disperse the concentrated water flow into umbrella-shaped and film-shaped water flow to disperse the impact force, and the cleaning component can clean the inner wall with the adjustment of the water flow speed each time, so as to avoid sludge adhering to the inner wall.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an anaerobic directional acclimation biological treatment device for hormone-based pharmaceutical wastewater, comprising a reaction tank, wherein an ascending pipe and a descending pipe are provided inside the reaction tank, and an external circulation pipe is provided outside the reaction tank, the lower end of the external circulation pipe being located at the lower end of the reaction tank, and the descending pipe comprising: A main connecting section, wherein a limiting component is fixedly installed within the main connecting section, and a piston hole is provided in the middle position of the limiting component; The secondary connection section and the main connection section are provided with multiple sets. The downcomer is composed of multiple sets of main connection sections and secondary connection sections connected in series alternately. A cleaning component is provided in the secondary connection section. The lower connecting section is located at the lower end of the downcomer pipe. A water outlet is fixedly installed at the lower end of the lower connecting section. A water guiding component is provided inside the water outlet. The water guiding component can reduce the impact force of falling water and can drive the cleaning component to move longitudinally. The cleaning assembly includes an inner connecting rod, with sealing plugs fixedly installed at both ends of the inner connecting rod. Multiple sets of cleaning scraper rings are equidistantly arranged on the inner connecting rod. The cleaning scraper rings are fixedly connected to the inner connecting rod through a fixing rod. The cleaning scraper rings can fit against the inner wall of the secondary connecting section. The sealing plugs match the piston hole. The water guiding assembly includes a rotating plate, a connecting plate, and a limiting plate symmetrically arranged above the water outlet component. The rotating plate is rotatably connected to the side wall of the water outlet component. The connecting plate is rotatably mounted on the upper surface of the rotating plate. A lower limiting rod is rotatably mounted on the upper end of the connecting plate. The lower limiting rod is inserted into the lower connecting section. The upper end of the lower limiting rod is fixedly connected to the sealing plug. The limiting plate is located at the top of the inner cavity of the water outlet component. The lower limiting rod is slidably connected to the limiting plate. A telescopic rod is provided between the upper surface of the rotating plate and the top of the water outlet component.
[0006] As a further embodiment of the present invention, the reaction vessel is provided with a mixing baffle, a primary three-phase separator, and a secondary three-phase separator. The mixing baffle is fixedly installed at the bottom of the reaction vessel, and the primary and secondary three-phase separators are installed at the upper end of the reaction vessel, with the primary three-phase separator located below the secondary three-phase separator. A primary anaerobic reaction chamber is formed between the mixing baffle and the primary three-phase separator, and a secondary anaerobic reaction chamber is formed between the primary three-phase separator and the secondary three-phase separator.
[0007] As a further embodiment of the present invention, the area above the secondary three-phase separator within the reaction tank is a gas-liquid separation zone. A biogas pipe is installed within the gas-liquid separation zone, with its upper end extending from the upper end of the reaction tank. An ascending pipe is installed within the reaction tank, with its lower end located in the secondary anaerobic reaction chamber. The lower end of the descending pipe is located below the mixing baffle. The upper ends of both the descending pipe and the ascending pipe are located within the gas-liquid separation zone.
[0008] As a further embodiment of the present invention, the upper end of the external circulation pipe is located on one side of the gas-water separation zone, and the lower end of the external circulation pipe is fixedly connected to a water inlet pipe. The water inlet pipe can guide sewage into the reaction tank, and the external circulation pipe can guide sewage in the gas-water separation zone back to the bottom of the reaction tank. Control valves are installed on both the external circulation pipe and the water inlet pipe.
[0009] As a further embodiment of the present invention, the upper surface of the limiting member is densely provided with upper screen holes, and the lower surface is densely provided with lower screen holes. The interior of the limiting member is hollow. Water in the downcomer can pass through the limiting member through the upper and lower screen holes, and can also pass through the limiting member through the piston hole.
[0010] As a further embodiment of the present invention, a seepage plate is fixedly installed at the bottom of the water outlet, and an arc plate is fixedly installed in the middle of the seepage plate via a connecting column, the upper surface of the arc plate being set as an arc surface.
[0011] As a further embodiment of the present invention, a folding plate is provided inside the water outlet component below the rotating plate. The folding plate has a raised center and gaps on both sides with the side wall of the water outlet component. A water guide roller is rotatably installed inside the water outlet component below the gaps. Multiple sets of water accumulation grooves are evenly opened on the outer surface of the water guide roller. A micro motor is provided on the outside of the water outlet component, and the output end of the micro motor is fixedly connected to the water guide roller.
[0012] As a further embodiment of the present invention, both ends of the secondary connecting section are provided with threaded sections, which can be adapted to connect with the threaded lines inside the main connecting section.
[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the anaerobic treatment of hormone drugs is carried out in a reaction tank. Wastewater enters the bottom of the reaction tank, and the wastewater after anaerobic treatment enters the upper part of the reaction tank through a riser pipe. The liquid after gas-liquid separation flows back to the bottom of the reaction tank through a downcomer pipe. The downcomer pipe is composed of alternating main connecting sections and secondary connecting sections connected in series. The bottom of the downcomer pipe consists of a lower connecting section and a water outlet. The limiting component in the main connecting section acts as a barrier during the liquid's fall. By using the limiting component as a buffer plate during the water's fall, the resistance of multiple sets of limiting plates reduces the water flow velocity, thereby reducing the impact force of the water falling to the bottom, reducing the impact kinetic energy, and thus reducing the possibility of the water impacting the bottom sludge bed.
[0014] In this invention, the water enters the outlet and is then output from its bottom. The water guiding component inside the outlet can control the liquid flow rate (the closer the lower ends of the two sets of rotating plates are, the smaller the water output of the outlet is, at which point the rotating plates are in a horizontal state). When the water guiding component adjusts the size of the outlet, it can drive the cleaning component to move up and down within the secondary connecting section, thereby cleaning the sludge adhering to the inner wall of the secondary connecting section through the cleaning component, avoiding blockage inside the downcomer pipe, which may cause the equipment to be obstructed.
[0015] In this invention, the downcomer consists of a main connecting section and a secondary connecting section, replacing the previous long, integrated downcomer. Since the downcomer is longer than the riser, it is inconvenient to install and more prone to damage. The shorter main connecting section serves as the main connection, making it easier to connect to the internal structure of the reaction vessel. The longer secondary connecting section connects between the main connecting sections and does not directly contact the main body of the reaction vessel. This allows for quick installation of the downcomer, and if it becomes clogged, only the secondary connecting section needs to be replaced, thus improving the installation efficiency of the downcomer.

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.
[0020] Please see Figures 1-10 This invention provides a technical solution: an anaerobic directional biological treatment device for hormone-based pharmaceutical wastewater, comprising a reaction tank 1, an ascending pipe 5 and a descending pipe 6 installed inside the reaction tank 1, and an external circulation pipe 2 installed outside the reaction tank 1, with the lower end of the external circulation pipe 2 located at the lower end of the reaction tank 1. The descending pipe 6 includes: Main connecting section 601, with a limiting component 14 fixedly installed inside the main connecting section 601, and a piston hole 1403 provided in the middle position of the limiting component 14; The secondary connection section 602 and the main connection section 601 are both provided with multiple sets. The downcomer 6 is formed by multiple sets of main connection sections 601 and secondary connection sections 602 connected in series alternately. A cleaning component is provided in the secondary connection section 602. The lower connecting section 603 is located at the lower end of the downcomer 6. A water outlet 15 is fixedly installed at the lower end of the lower connecting section 603. A water guiding component is provided inside the water outlet 15. The water guiding component can reduce the impact force of falling water and can drive the cleaning component to move longitudinally. The cleaning assembly includes an inner connecting rod 10, with sealing plugs 13 fixedly installed at both ends of the inner connecting rod 10. Multiple sets of cleaning scraper rings 11 are equidistantly arranged on the inner connecting rod 10. The cleaning scraper rings 11 are fixedly connected to the inner connecting rod 10 through a fixing rod 12. The cleaning scraper rings 11 can fit against the inner wall of the secondary connecting section 602. The sealing plugs 13 match the piston holes 1403. The water guiding assembly includes a rotating plate 19, a connecting plate 21, and a limiting plate 24 symmetrically arranged above the water outlet 15. The rotating plate 19 is rotatably connected to the side wall of the water outlet 15. The connecting plate 21 is rotatably mounted on the upper surface of the rotating plate 19. A lower limiting rod 16 is rotatably mounted on the upper end of the connecting plate 21. The lower limiting rod 16 is inserted into the lower connecting section 603. The upper end of the lower limiting rod 16 is fixedly connected to the sealing plug 13. The limiting plate 24 is located at the top of the inner cavity of the water outlet 15. The lower limiting rod 16 is slidably connected to the limiting plate 24. A telescopic rod 22 is provided between the upper surface of the rotating plate 19 and the top of the water outlet 15.
[0021] During operation, the anaerobic treatment of the hormone drug in this invention is carried out in the reaction tank 1. Wastewater enters the bottom of the reaction tank 1, and the wastewater after anaerobic reaction treatment enters the upper part of the reaction tank 1 through the riser pipe 5. The liquid after gas-liquid separation flows back to the bottom of the reaction tank 1 through the downcomer pipe 6. The downcomer pipe 6 is composed of a main connecting section 601 and a secondary connecting section 602 connected in series. The bottom of the downcomer pipe 6 is composed of a lower connecting section 603 and a water outlet 15. The limiting member 14 in the main connecting section 601 acts as a barrier during the liquid's fall. By using the limiting member 14 as a buffer plate during the water's fall, the resistance of multiple sets of limiting plates 24 is used to reduce the water flow velocity, thereby reducing the impact force of the water falling to the bottom, reducing the impact kinetic energy, and thus reducing the possibility of the water impacting the bottom sludge bed. In this invention, the water enters the outlet 15 and is then output from its bottom. The water guiding component inside the outlet 15 can control the liquid flow rate (the closer the lower ends of the two sets of rotating plates 19 are, the smaller the water output of the outlet 15 is, at which time the rotating plates 19 are in a horizontal state). When the water guiding component adjusts the size of the outlet, it can drive the cleaning component to move up and down in the secondary connecting section 602, thereby cleaning the sludge adhering to the inner wall of the secondary connecting section 602 through the cleaning component, avoiding the possibility of blockage inside the downcomer 6, which may cause the equipment to be obstructed. In this invention, the downcomer 6 is composed of a main connecting section 601 and a secondary connecting section 602, replacing the previous long, integrated downcomer 6. Since the downcomer 6 is longer than the riser 5, it is inconvenient to install and more prone to damage. The shorter main connecting section 601 serves as the main connecting body, making it easier to connect with the internal structure of the reaction vessel 1. The longer secondary connecting section 602 connects between the main connecting sections 601 and does not directly contact the main body of the reaction vessel 1. This allows for quick installation of the downcomer 6, and if it becomes blocked, only the secondary connecting section 602 needs to be replaced, thus improving the installation efficiency of the downcomer 6.
[0022] In this invention, the cleaning ring 11 is fixedly connected to the inner connecting rod 10. When the inner connecting rod 10 is at the upper end, the sealing plug 13 is inside the piston hole 1403 of the limiting member 14. The sealing plug 13 blocks the piston hole 1403 in the middle of the limiting member 14. The inner connecting rod 10 moves down, causing the sealing plug 13 to gradually separate from the piston hole 1403, so that the water can gradually fall from the piston hole 1403. When the inner connecting rod 10 falls to the lowest point, the piston hole 1403 is fully open. At this time, the water flow in the downcomer 6 is the largest. As the inner connecting rod 10 moves up and down, the cleaning scraper ring 11 can clean the inner wall of the secondary connecting section 602 to a certain extent, avoiding a large amount of sludge from adhering to the inner wall of this connecting section 602, thereby causing the downcomer 6 to be blocked.
[0023] In this invention, the extension or retraction of the telescopic rod 22 drives the rotating plate 19 to rotate. When the rotating plate 19 rotates to the horizontal position, the two sets of rotating plates 19 are closest to each other, and the water outlet of the water outlet 15 is at its smallest. When the telescopic rod 22 extends, the rotating plate 19 rotates downward, and the two sets of rotating plates 19 move away from each other. At this time, the water outlet of the water outlet 15 is at its largest. When the rotating plate 19 rotates downward, the connecting plate 21 pulls the lower limit rod 16 downward, and the downward movement of the lower limit rod 16 drives multiple sets of cleaning components downward, thereby causing the sealing plug 13 to disengage from the piston hole 1403. At this time, the water flow rate of the downcomer 6 is at its maximum.
[0024] As a further embodiment of the present invention, the reaction vessel 1 is provided with a mixing baffle 7, a primary three-phase separator 8, and a secondary three-phase separator 9. The mixing baffle 7 is fixedly installed at the bottom of the reaction vessel 1, the primary three-phase separator 8 and the secondary three-phase separator 9 are installed at the upper end of the reaction vessel 1, and the primary three-phase separator 8 is located below the secondary three-phase separator 9. A primary anaerobic reaction chamber is formed between the mixing baffle 7 and the primary three-phase separator 8, and a secondary anaerobic reaction chamber is formed between the primary three-phase separator 8 and the secondary three-phase separator 9.
[0025] During operation, the present invention uses a primary anaerobic reaction chamber and a secondary anaerobic reaction chamber for anaerobic reaction of wastewater, the area below the mixing baffle 7 for mixing wastewater with the sludge bed, and a primary three-phase separator 8 and a secondary three-phase separator 9 for treating and filtering the wastewater.
[0026] As a further embodiment of the present invention, the area above the secondary three-phase separator 9 inside the reaction tank 1 is a gas-water separation zone. A biogas pipe 4 is installed in the gas-water separation zone. The upper end of the biogas pipe 4 is led out from the upper end of the reaction tank 1. An ascending pipe 5 is installed inside the reaction tank 1. The lower end of the ascending pipe 5 is located in the secondary anaerobic reaction chamber. The lower end of the descending pipe 6 is located below the mixing baffle 7. The upper ends of both the descending pipe 6 and the ascending pipe 5 are located in the gas-water separation zone.
[0027] During operation, the riser pipe 5 of this invention introduces sewage into the gas-water separation zone, biogas is discharged to the outside of the reaction tank 1 through the biogas pipe 4, and unqualified sewage flows back to the bottom of the reaction tank 1 through the downcomer pipe 6.
[0028] As a further embodiment of the present invention, the upper end of the external circulation pipe 2 is located on one side of the gas-water separation zone, and the lower end of the external circulation pipe 2 is fixedly connected to the water inlet pipe 3. The water inlet pipe 3 can guide sewage into the reaction tank 1, and the external circulation pipe 2 can guide the sewage in the gas-water separation zone back to the bottom of the reaction tank 1. Control valves are installed on both the external circulation pipe 2 and the water inlet pipe 3.
[0029] During operation, a portion of the gas and liquid in this invention is returned to the bottom of the reaction tank 1 through the external circulation pipe 2 to prevent acid accumulation at the bottom of the reaction tank. The forced circulation optimizes the reaction conditions and compensates for the insufficient power of the internal circulation.
[0030] As a further embodiment of the present invention, the upper surface of the limiting member 14 is densely provided with upper screen holes 1401, and the lower surface is densely provided with lower screen holes 1402. The interior of the limiting member 14 is hollow. Water in the downcomer 6 can pass through the limiting member 14 through the upper screen holes 1401 and the lower screen holes 1402, and can also pass through the limiting member 14 through the piston hole 1403.
[0031] During operation, water passes through the upper screen hole 1401 and lower screen hole 1402 of the limiting member 14. At this time, the water volume is small and the water falls slowly. However, when the sealing plug 13 is pulled out from the piston hole 1403, the water passes through the upper screen hole 1401, lower screen hole 1402 and piston hole 1403, thereby maximizing the water flow rate.
[0032] As a further embodiment of the present invention, a lower infiltration plate 18 is fixedly installed at the bottom of the water outlet 15, and an arc plate 23 is fixedly installed in the middle of the lower infiltration plate 18 through a connecting column, and the upper surface of the arc plate 23 is set as an arc surface.
[0033] During operation, the water in the water outlet 15 of this invention flows to the surface of the arc plate 23 through the infiltration plate 18. The arc plate 23 can disperse the concentrated water flow into an umbrella-shaped or film-shaped water flow, so that the water disperses the impact force and avoids the falling water from impacting the silt bed.
[0034] As a further embodiment of the present invention, a folding plate 20 is provided below the rotating plate 19 inside the water outlet component 15. The folding plate 20 has a raised middle section and gaps on both sides with the side walls of the water outlet component 15. A water guide roller 17 is rotatably installed below the gap inside the water outlet component 15. Multiple sets of water accumulation grooves 1701 are evenly opened on the outer surface of the water guide roller 17. A micro motor is provided on the outer side of the water outlet component 15, and the output end of the micro motor is fixedly connected to the water guide roller 17.
[0035] During operation, the water flows directly out of the movable plate 19 and falls along the folded plate 20. The falling water passes through the rotating water guide roller 17. After the water is stored in the water accumulation tank 1701 on the water guide roller 17, the water is dispersed and scattered by centrifugal force, further dispersing the water.
[0036] As a further embodiment of the present invention, threaded sections 25 are provided at both ends of the secondary connecting section 602, and the threaded sections 25 can be adapted to connect with the threaded lines inside the main connecting section 601.
[0037] During operation, the main connecting section 601 and the secondary connecting section 602 are connected by threads to increase the installation speed of the downcomer 6.
[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
