Description

Technical Field

[0001] This utility model relates to the field of bioreactor technology, and in particular to a bioreactor for the degradation and treatment of rural domestic sewage. Background Technology

[0002] Biological reactors for rural domestic sewage degradation are a highly efficient and economical sewage treatment technology widely used in rural areas. Their core principle is the degradation of organic pollutants in sewage through the metabolic processes of microorganisms. Combined with an aeration system that provides oxygen, this promotes the growth and reproduction of aerobic microorganisms, thereby achieving efficient sewage purification. A biological reactor typically consists of an influent system, an aeration system, a sludge return system, and an effluent system. Sewage is first pretreated through a screen and grit chamber to remove large particles before entering the biological reactor. The aeration system injects air into the tank using blowers or mechanical aeration equipment to ensure the dissolved oxygen concentration in the water is maintained at a suitable level, creating a favorable living environment for aerobic microorganisms. Microorganisms use the organic matter in the sewage as a nutrient source, converting it into carbon dioxide, water, and cellular matter through adsorption, decomposition, and oxidation, thus removing pollutants. After sedimentation, the supernatant in the mixed liquor in the reactor is discharged as treated effluent or reused, some of the settled sludge is returned to the reactor to maintain the microbial concentration, and the remaining sludge undergoes further treatment. Biological reactors offer advantages such as high treatment efficiency, stable operation, ease of use, and strong adaptability, making them particularly suitable for decentralized wastewater treatment needs in rural areas. Their design requires comprehensive consideration of wastewater quality, quantity, climate conditions, and local economic levels. They typically employ process variations such as extended aeration, sequencing batch reactors (SBR), or membrane bioreactors (MBR) to improve treatment efficiency. With proper maintenance and management, biological reactors can operate stably for extended periods, effectively addressing environmental pollution caused by direct discharge of rural domestic sewage, improving the rural living environment, and contributing to the construction of beautiful villages.

[0003] A search of Chinese patent "An Aeration Tank" (publication number CN208933069U) reveals that the tank includes a tank body with an air distribution pipe laid at the bottom. Several aerators are spaced apart on the upper side of the air distribution pipe. The air distribution pipe extends out of the tank body and is connected to a blower. Each aerator includes a fixed base and a fixed cover, with an aeration plate positioned between the fixed base and the fixed cover. A connecting assembly is located on the side of the fixed base opposite to the fixed cover. The connecting assembly includes a connecting strap, one end of which is fixedly connected to the connecting base, and the other end is a fixed end. The connecting base has a connecting hole for the fixed end to pass through, and a connecting bolt threaded onto the outer side of the connecting base extends into the connecting hole. By adjusting the length of the fixed end passing through the connecting base, the size of the ring formed by the connecting strap can be changed, allowing the fixed base to be attached to air distribution pipes of various diameters, thus broadening its applicability.

[0004] In existing technologies, aeration pipes are added to the biological reactor, and a continuous supply of oxygen is generated through an aeration generator. The oxygen is then transported to the water in the reactor through the aeration pipes, which helps aerobic microorganisms degrade wastewater. However, floating organic or inorganic matter in the water tends to accumulate on the surface of the aeration pipes, and if it is not cleaned for a long time, it will affect the aeration effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In practical implementation: such as Figures 1-4 As shown, a biological reactor for the degradation and treatment of rural domestic sewage includes:

[0028] Reaction tank 1;

[0029] The aeration generating device body 10 is located inside the reaction tank body 1;

[0030] Four-way disc 12 is fixedly connected to the lower end of the aeration generator body 10;

[0031] Aeration pipe body 13 is provided in multiple forms, and multiple aeration pipe bodies 13 are fixedly connected to the surface interface of the four-way disc 12.

[0032] The cleaning assembly comprises multiple sets, each set of which is connected to multiple aeration pipe bodies 13. Each cleaning assembly includes a rotating block 19, a rotating shaft 14, a cleaning plate 18, a rotating frame 15, a spiral blade 16, and a rotating ring 17. Multiple cleaning plates 18 are provided. The rotating ring 17 is rotatably connected to one end of the aeration pipe body 13, and the rotating block 19 is rotatably connected to the other end of the aeration pipe body 13. Multiple cleaning plates 18 are fixedly connected to the surfaces of the rotating block 19 and the rotating ring 17. The rotating frame 15 is fixedly connected to the inner circumference of the aeration pipe body 13. The rotating shaft 14 is fixedly connected to one end of the rotating block 19 and rotatably connected inside the rotating frame 15. The spiral blade 16 is fixedly connected to one end of the rotating shaft 14.

[0033] In this embodiment: the reaction tank 1 is used to store rural domestic sewage. The sewage is degraded by aerobic microorganisms within the reaction tank 1. Oxygen is generated by the operation of the aeration generator 10. The oxygen enters the aeration pipe body 13 through the four-way disc 12 and is then introduced into the tank water through the aeration holes of the aeration pipe body 13, increasing the oxygen content in the water and aiding in the treatment of sewage by aerobic microorganisms. To prevent the accumulation of suspended organic and inorganic matter on the surface of the aeration pipe body 13, a cleaning component is installed in each aeration pipe body 13. Multiple cleaning plates 18 are rotatably connected to the aeration pipe body 13. On the circumferential surface of the aeration tube body 13, a rotating shaft 14 is connected to a rotating block 19. A spiral blade 16 is installed at one end of the rotating shaft 14. The rotating frame 15 supports the rotating shaft 14. When oxygen is input into the aeration tube body 13 through the four-way disc 12, the oxygen blows the spiral blade 16, causing the spiral blade 16 to rotate. When the spiral blade 16 rotates, it drives the rotating shaft 14 to rotate. Then, the rotating block 19 drives the cleaning plate 18 to rotate. When the cleaning plate 18 rotates, it removes the organic or inorganic matter accumulated on the circumferential surface of the aeration tube body 13, thus preventing the accumulation of organic or inorganic matter.

[0034] like Figures 1-4 As shown, multiple telescopic rods 2 are fixedly connected to the upper end of the reaction tank body 1, and a top plate 3 is fixedly connected to the upper end of the multiple telescopic rods 2.

[0035] In this embodiment: the telescopic rod 2 consists of a sleeve and a thin rod. The sleeve is fixed to the upper end of the reaction tank body 1, and the thin rod is slidably connected inside the sleeve. The thin rod is connected to the top plate 3. The telescopic rod 2 is used to limit the top plate 3 and improve the stability of the top plate 3 when it is raised and lowered. The top plate 3 serves to install the central column 6.

[0036] like Figures 1-4 As shown, a rotating assembly is provided on the upper side of the reaction tank 1. The rotating assembly is connected to the four-way disk 12. The rotating assembly includes a central column 6, a rotating disk 7, a gear 8, and connecting rods 11. Multiple connecting rods 11 are provided. The central column 6 is fixedly connected to the inner circumference of the top plate 3. Multiple connecting rods 11 are fixedly connected to the upper end of the four-way disk 12. The rotating disk 7 is fixedly connected to the upper end of the multiple connecting rods 11. A toothed ring is provided on the inner circumference of the rotating disk 7. The rotating disk 7 is rotatably connected to the surface of the central column 6. The motor 9 is fixedly connected to the lower end of the central column 6. The output end of the motor 9 moves through the surface of the central column 6 and extends upward. The gear 8 is fixedly connected to the output end of the motor 9. The gear 8 meshes with the toothed ring.

[0037] In this embodiment: the rotating disk 7 in the rotating assembly is rotatably connected to the surface of the central column 6, and the rotating disk 7 is limited so that it will not fall off the surface of the central column 6. When the motor 9 fixed at the lower end of the central column 6 is running, it drives the gear 8 connected to its output end to rotate. The gear 8 meshes with the gear ring, and the rotation of the gear 8 drives the rotation of the rotating disk 7. The rotating disk 7 drives the four-way disk 12 to rotate through the connecting rod 11, which indirectly drives the rotation of multiple aeration pipe bodies 13. When the aeration pipe bodies 13 rotate, they aerate different positions in the pool water, effectively improving the aeration effect.

[0038] like Figures 1-4 As shown, lifting components are provided on both sides of the reaction tank 1. Each lifting component includes a fixed plate 4 and a cylinder 5. There are two fixed plates 4, which are fixedly connected to the top plate 3 and the circumferential surface of the reaction tank 1, respectively. The cylinder 5 is fixedly connected to the surface of the lower fixed plate 4, and the extended end of the cylinder 5 is fixedly connected to the lower end of the upper fixed plate 4.

[0039] In this embodiment: When the two sets of lifting components are running, the extended end of the cylinder 5 drives the top plate 3 to rise and fall through the fixed plate 4. When the top plate 3 rises and falls, it drives the four-way disc 12 to rise and fall through the rotating component. The four-way disc 12 drives multiple aeration pipe bodies 13 to rise and fall, which makes it easy to adjust the height of the aeration pipe bodies 13 in the water, making it easy to aerate different positions and improve the aeration effect.

[0040] like Figures 1-4 As shown, multiple aeration holes are provided on the circumferential surface of the multiple aeration pipe bodies 13.

[0041] In this embodiment, oxygen enters the pool water through the aeration holes on the surface of the aeration pipe body 13. A filter screen is installed inside the aeration holes to prevent sludge from entering the aeration pipe body 13.

[0042] like Figures 1-4 As shown, the four-way disc 12 is connected to the main body 10 of the aeration generating device, and the four-way disc 12 is connected to the main bodies 13 of multiple aeration pipes.

[0043] In this embodiment, the oxygen generated by the aeration generator body 10 is diverted through the four-way disc 12 and enters the multiple aeration pipe bodies 13.

[0044] like Figures 1-4 As shown, multiple cleaning plates 18 are respectively attached to the circumferential surfaces of multiple aeration pipe bodies 13.

[0045] In this embodiment: the cleaning plate 18 is attached to the surface of the aeration pipe body 13, and the cleaning plate 18 scrapes off the sludge on the surface of the aeration pipe body 13 when it rotates.

[0046] It should be noted that the cylinder 5, motor 9 and aeration generator body 10 used in this device are all existing technologies. The specific models of cylinder 5, motor 9 and aeration generator body 10 can be selected according to actual needs, which will not be elaborated on here.

[0047] In use, this invention involves injecting rural domestic sewage into the reaction tank 1. The aeration generator 10 generates oxygen, which enters the aeration pipe 13 through the four-way disc 12. The oxygen then flows into the tank water through the aeration holes of the aeration pipe 13, increasing the oxygen content and aiding in the treatment of sewage by aerobic microorganisms. During operation, the aeration generator 10 drives the cleaning components. When oxygen enters the aeration pipe 13 through the four-way disc 12, it blows the spiral blades 16, causing them to rotate. The rotating blades 16 then rotate the rotating shaft 14, which in turn rotates through the rotating block 19. The rotating block 19 drives the cleaning plate 18 to rotate. When the cleaning plate 18 rotates, it removes the organic or inorganic matter accumulated on the circumferential surface of the aeration pipe body 13, thus preventing the accumulation of organic or inorganic matter. During the aeration process, the operation of the lifting component and the rotating component is controlled to adjust the position of the aeration pipe body 13 in the pool water at multiple angles. By using this device, the aeration generator body 10 drives the cleaning component to operate during operation. The cleaning component removes the organic or inorganic matter accumulated on the circumferential surface of the aeration pipe body 13, thus preventing the accumulation of organic or inorganic matter and avoiding the impact of accumulated organic or inorganic matter on the aeration effect of the aeration pipe.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
