Description

Technical Field

[0001] This invention relates to the field of water pollution treatment equipment technology, and in particular to a rotary microbial carrier water pollution purification device. Background Technology

[0002] In the field of water pollution control, rotary microbial carrier water pollution purification equipment plays an important role in wastewater treatment due to its highly efficient pollutant degradation capabilities. However, existing equipment of this type has some significant problems in actual operation and maintenance.

[0003] Rotary disc maintenance and replacement are difficult: In traditional rotary microbial carrier water pollution purification equipment, the discs are usually mounted on the same shaft. When the discs are damaged due to physical wear, chemical corrosion, biological erosion, or operational errors, the maintenance and replacement process is extremely cumbersome. It requires removing the entire shaft along with the discs from the equipment, disassembling the discs one by one, replacing the damaged discs, reassembling, and finally reinstalling them. This not only consumes a lot of time and manpower, but the complex operation can also easily cause unnecessary damage to other components of the equipment. For example, in some large-scale wastewater treatment plants, with their large equipment size, this complex maintenance and replacement process can lead to prolonged equipment downtime, affecting the overall wastewater treatment progress.

[0004] Microbial community balance is affected: Due to the large number of microorganisms adhering to the rotating disc, traditional maintenance and replacement methods expose the disc to air for extended periods. This severely disrupts the microbial community balance on the disc, requiring a lengthy period for readjustment of the microbial community after the disc is reinstalled in the equipment to restore its wastewater treatment capacity. During this period, wastewater treatment efficiency is significantly reduced, failing to meet actual wastewater treatment needs. For example, when treating industrial wastewater with high water quality requirements, the disruption of the microbial community balance may lead to substandard treated water quality.

[0005] Limited equipment operating efficiency: Frequent and complex maintenance and replacement operations, as well as the microbial colony establishment period, severely limit the overall operating efficiency of the equipment. Prolonged equipment downtime not only affects the daily treatment capacity of the wastewater treatment plant but may also increase treatment costs. Furthermore, the uncertainty of the microbial colony recovery process introduces instability into the wastewater treatment outcome. Summary of the Invention

[0006] In order to overcome the shortcomings of existing rotary microbial carrier water pollution purification equipment in terms of maintenance and replacement, and to improve the equipment operating efficiency and sewage treatment effect, it is urgent to develop a purification equipment that can easily and quickly replace the rotating disc and has little impact on the microbial colony.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses a rotary microbial carrier water pollution purification device. (Refer to...) Figure 1-8The purification equipment includes a semi-cylindrical reaction tank 1 and a rotating microbial carrier unit 2. One end of the reaction tank 1 is connected to an inlet pipe 11, and the other end is connected to an outlet pipe 12. The reaction tank 1 has multiple reaction chambers arranged sequentially from the inlet to the outlet. Each reaction chamber contains a microbial carrier unit 2, which includes a rotating shaft 21, a rotating shaft 22, multiple connecting shafts 23, multiple mounting shafts 24, and multiple turntables 25. A first mounting ring 211 is rotatably connected to the outer circumference of the rotating shaft 21 via bearings. The circumference of the first mounting ring 211 is connected to the top surface of the reaction tank 1 via two symmetrically arranged first connecting rods 212. A second mounting ring 221 is rotatably connected to the outer circumference of the rotating shaft 22 via bearings. The circumference of the second mounting ring 221 is connected to the top surface of the reaction tank 1 via two symmetrically arranged second connecting rods 222. The rotating shafts 21 and 22 are connected in parallel. Axis; Multiple connecting shafts 23 are arranged between rotating shaft 21 and rotating shaft 22 along the axis of rotating shaft 22. The outer circumference of the connecting shaft 23 is rotatably connected to a third mounting ring 231 via bearings. The circumference of the third mounting ring 231 is mounted on the top surface of the reaction tank 1 via two symmetrically arranged third connecting rods 232. Multiple connecting shafts 23 and multiple mounting shafts 24 are staggered. The two ends of the connecting shaft 23 are detachably connected to the ends of two adjacent mounting shafts 24 that are close to each other. The end of the rotating shaft 22 is detachably connected to the end of the nearest mounting shaft 24. The end of the rotating shaft 21 is detachably connected to the end of the nearest mounting shaft 24. The number of turntables 25 is the same as the number of mounting parts. Multiple turntables 25 are detachably connected to the middle position of the mounting parts. The turntables 25 are used for microbial attachment. A drive mechanism 3 for driving the rotating shaft 22 to rotate is provided on one side of the reaction tank 1. Each rotating shaft 22 corresponds to one drive mechanism 3.

[0034] The inlet pipe 11 introduces pre-treated wastewater into the reaction tank 1. The drive mechanism 3 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the connecting shaft 23 to rotate together through the connected mounting shaft 24. The rotating shaft 21 also rotates together with the mounting shaft 24. The mounting shaft 24 drives the turntable 25 to rotate in the reaction tank 1. The wastewater passes through multiple reaction chambers in sequence. The lower part of the turntable 25 is immersed in the wastewater. The wastewater flows through each reaction chamber in sequence, and the pollutants are degraded step by step. Finally, the treated wastewater is discharged to the subsequent process section through the outlet pipe 12. By installing the turntable 25 on an independent mounting shaft 24, and the mounting shaft 24 is detachably connected to the connecting shaft 23, the rotation of the rotating shaft 22 is stopped, the damaged turntable 25 mounting shaft 24 is removed from the two adjacent connecting shafts 23, and the mounting shaft 24 of the undamaged turntable 25 is installed on the two adjacent connecting shafts 23. This allows for quick replacement without removing the entire rotating microbial carrier unit 2 from the reaction tank 1, improving replacement efficiency and further improving wastewater treatment efficiency.

[0035] In the embodiments of this application, the reaction grid is set to six levels, namely, level 1 reaction grid 101, level 2 reaction grid 102, level 3 reaction grid 103, level 4 reaction grid 104, level 5 reaction grid 105 and level 6 reaction grid 106.

[0036] The primary reaction chamber 101 has the highest concentration of organic matter in the wastewater (BOD5 is typically 150-300 mg / L), with a biofilm thickness of 0.8-2.0 mm. It is dominated by heterotrophic aerobic bacteria, supplemented by a small number of facultative bacteria. It degrades 60%-70% of BOD5 and COD in the wastewater and is the core area for organic matter removal. In the secondary to quaternary reaction chambers 104, after primary treatment, the concentration of organic matter in the wastewater decreases (BOD5 drops to 50-150 mg / L), the biofilm thickness is 0.5-1.2 mm, the proportion of heterotrophic bacteria decreases, and the proportion of autotrophic nitrifying bacteria gradually increases. It continues to degrade the remaining easily degradable organic matter and simultaneously completes the nitrification reaction of ammonia nitrogen (ammonia nitrogen removal rate 50%-70%). In stage 5 to 6 reaction chamber 106, the organic matter concentration of wastewater is already low (BOD5 < 50 mg / L), the biofilm thickness is 0.3-0.8 mm, and it is dominated by autotrophic nitrifying bacteria and facultative denitrifying bacteria. During disc drainage, a local anaerobic microenvironment is formed; the remaining ammonia nitrogen is nitrified, and denitrification (conversion of nitrate nitrogen to nitrogen gas) is achieved in the anaerobic microenvironment; further degradation of recalcitrant organic matter.

[0037] Positioning plates 241 are connected to the middle of both ends of the mounting shaft 24. A mating plate 233 is connected to the bottom of both ends of the connecting shaft 23, the bottom of the end face of the rotating shaft 21, and the bottom of the end face of the rotating shaft 22. The mating plate 233 is a semi-cylinder with its side facing upwards. Positioning grooves 2331 that mate with the positioning plates 241 are provided on the side of the mating plate 233. The positioning plate 241 is connected to the mating plate 233 by bolts 242. Multiple rows of threaded holes 2332 are evenly arranged along the axis of the mating plate 233 on the bottom surface of the positioning grooves 2331. There are two threaded holes 2332 in each row. Two bolts 242 pass through the end of the positioning plate 241, and the two bolts 242 are threaded into the two threaded holes 2332 in each row.

[0038] When removing the mounting shaft 24 from the connecting shaft 23, rotate the mounting shaft 24 so that the positioning groove 2331 faces upward, unscrew the bolt 242 at the end of the positioning plate 241, release the restriction between the positioning plate 241 and the mating plate 233, and then remove the positioning plate 241 from the positioning groove 2331, and then remove the mounting shaft 24. When it is necessary to install the mounting shaft 24, align the positioning plate 241 with the positioning groove 2331, align the bolt 242 with the threaded hole 2332, insert the bolt 242 into the positioning plate 241, and screw the bolt 242 into the threaded hole 2332. The purpose of setting multiple rows of threaded holes 2332 is to adjust the distance between the turntables 25 and change the density between the turntables 25. At the same time, different lengths of mounting shaft 24 and connecting shaft 23 can be selected according to the requirements.

[0039] The end of the third connecting rod 232 on the same side away from the third positioning ring is connected to the mounting plate 234. The top surface of the reaction tank 1 is provided with a clearance groove 13 for the third connecting rod 232 to be placed. The mounting plate 234 is attached to the outer side of the reaction tank 1 and can be detachably connected to the outer side of the reaction tank 1.

[0040] The third connecting rod 232, the third mounting ring 231 and the connecting shaft 23 are connected as a whole by the mounting plate 234, and the connecting shaft 23 can be installed on the reaction tank 1 at the same time, which is more convenient.

[0041] In each rotating microbial carrier unit 2, a turntable 25 close to the rotating shaft 22 is a spare turntable 26. The spare turntable 26 is located at the end of the sewage flow direction and rotates together with the other turntables 25.

[0042] Within each reaction chamber, the remaining rotating discs 25 are responsible for the main wastewater treatment, while the spare rotating disc 26 also treats wastewater, but is not used for the treatment of wastewater in the current reaction chamber. If a rotating disc 25 is damaged in the current reaction chamber, the spare rotating disc 26 can be used to replace the damaged disc 25, and then a new rotating disc 25 can be placed in the position of the spare rotating disc 26 to cultivate the microorganisms on the new rotating disc 25. By rotating the remaining rotating discs 25 together, the cultivation time of the microorganisms can be saved, and the normal treatment of wastewater can be unaffected.

[0043] Each rotating microbial carrier unit 2 is provided with an adjustment mechanism 4, which is used to adjust the positioning groove 2331 to face upwards. The adjustment mechanism 4 includes a guide shaft 41, a sliding shaft 42, and a return spring 43. A fourth mounting ring 411 is rotatably connected to the circumference of the guide shaft 41 via a bearing. The circumference of the fourth mounting ring 411 is connected to the top surface of the reaction tank 1 via two stacked fourth connecting rods 412. A guide plate 413 is connected to the guide shaft 41 near the middle of the end face of the rotating shaft 22. The end face of the guide plate 413 is trapezoidal. The sliding shaft 42 has a through hole 421 along its axis in the middle that cooperates with the guide plate 413. The sliding shaft 42 slides on the surface of the guide plate 413; a counterweight 422 is connected to the bottom circumferential surface of the sliding shaft 42; a rotating plate 223 that cooperates with the through hole 421 is connected to the end face of the rotating shaft 22 near the guide shaft 41, and the end of the rotating plate 223 is close to the end of the guide plate 413; a limit ring 224 is connected to the circumferential surface of the rotating shaft 22, a limit tube 423 is connected to the end face of the sliding shaft 42, a return spring 43 is sleeved on the outside of the rotating shaft 22, one end of the return spring 43 is pressed against the limit ring 224, and the other end of the return spring 43 is pressed against the end face of the sliding shaft 42 and located inside the limit tube 423; a pushing mechanism 5 for pushing the sliding shaft 42 is installed on one side of the reaction tank 1.

[0044] During the rotation of the rotating shaft 22, the pushing mechanism 5 pushes the sliding shaft 42 to move towards the rotating shaft 22. The sliding shaft 42 slides on the guide plate 413 and compresses the return spring 43. At this time, the end face of the sliding shaft 42 is in contact with the end face of the rotating plate 223. The rotating plate 223 rotates with the rotating shaft 22 until the rotating plate 223 is aligned with the through hole 421. At this time, the positioning groove 2331 faces upward. Then, the pushing mechanism 5 pushes the sliding shaft 42 towards the rotating plate 223. The rotating plate 223 inserts into the through hole 421 and stops driving the rotating shaft 22 to rotate. At this time, the rotating shaft 22 has inertia and will continue to rotate a certain distance. The rotating shaft 22 drives the sliding shaft 42 and the guide shaft 41 to rotate through the rotating plate 223. The counterweight 422 also rotates. After the rotation stops, under the gravity adjustment of the counterweight 422, the positioning groove 2331 returns to vertical and faces upward, which facilitates the installation and removal of the shaft 24.

[0045] The pushing mechanism 5 includes a semi-circular arc plate 51, a connecting frame 52, a guide rod 53, a slide tube 54, a pushing spring 55, and a pushing ring 56. One end of the guide rod 53 is connected to the outer side of the top of the reaction tank 1 via two support rods, and the slide tube 54 slides on the outer circumferential surface of the guide rod 53. The connecting frame 52 is horizontally arranged, and its bottom surface is connected to the circumferential surface of the slide tube 54. The inner circumferential surface of the semi-circular arc plate 51 is rotatably connected to the outer circumferential surface of the sliding shaft 42 via bearings. The semi-circular arc plate 51 is located in the upper half of the sliding shaft 42. One end of the frame 52 is connected to the outer circumferential surface of the semi-circular plate 51; the other end of the guide rod 53 is connected to a retaining ring 531, and the pushing ring 56 slides on the guide rod 53 and is located between the slide tube 54 and the retaining ring 531, with the pushing ring 56 fitting against the side of the retaining ring 531; the pushing spring 55 is sleeved on the guide rod 53, with one end of the pushing spring 55 pressing against the end face of the slide tube 54 and the other end of the pushing spring 55 pressing against the side of the pushing ring 56; a pushing assembly 6 for pushing the pushing ring 56 is provided on one side of the reaction tank 1.

[0046] The pushing component 6 pushes the pushing ring 56, which compresses the pushing spring 55. Since the rotating plate 223 is not inserted into the through hole 421, the end face of the rotating plate 223 is in contact with the end face of the sliding shaft 42. The sliding shaft 42 restricts the semi-circular plate, the connecting frame 52, and the slide tube 54 from moving forward. Therefore, the pushing spring 55 is compressed on the end face of the slide tube 54. After being compressed for a certain distance, the pushing ring 56 is stopped. As the rotating plate 223 continues to rotate, when the through hole 421 is aligned with the rotating plate 223, the restriction of the sliding shaft 42 on the rotating plate 223 is released. The pushing spring 55 pushes the slide tube 54, which drives the connecting frame 52. The connecting frame 52 drives the semi-circular plate 51, which drives the sliding shaft 42 to move forward, so that the rotating plate 223 is inserted into the through hole 421, thus achieving the positioning of the rotating plate 223.

[0047] A support frame 7 is installed at the bottom of the reaction tank 1 to support the reaction tank 1; the pushing assembly 6 includes a base plate 61, linear guide rails 62, lead screw 63, drive motor 64, sliding plate 65, lifting motor 66, upright plate 67, screw 68, and lifting frame 69; the base plate 61 is mounted on the side of the support frame 7 via a plate, and the base plate 61 is located below all the guide rods 53; two linear guide rails 62 are provided, and the two linear guide rails 62 are respectively installed on both sides of the base plate 61 and arranged along the length direction of the base plate 61; the drive motor 64 is installed on the top surface of one end of the base plate 61, and the lead screw 63 is coaxially connected to the output shaft of the drive motor 64. The lead screw 63 is located between the two linear guide rails 62, and the two ends of the lead screw 63 are connected by shafts. Support bases are installed at both ends of the base plate 61; the slide plate 65 is slidably connected to the linear guide rail 62 via a slider, and the lead screw 63 passes through the slide plate 65 and drives the slide plate 65 to slide; the upright plate 67 is installed on the top surface of the slide plate 65, and the upright plate 67 is located below the guide rod 53; the lifting frame 69 is slidably connected to the upright plate 67, and the top of the lifting frame 69 is provided with an arc-shaped opening 691 for the retaining ring 531 to pass through; the lifting motor 66 is vertically installed on the bottom surface of the slide plate 65, and the base plate 61 is provided with a through groove 611 for the lifting motor 66 to move; one end of the screw 68 is connected to the output shaft of the lifting motor 66, the screw 68 passes through the slide plate 65 and extends into the upright plate 67, and the screw 68 is threadedly connected to the bottom of the lifting frame 69.

[0048] When the push spring 55 needs to be compressed, the drive motor 64 drives the lead screw 63 to rotate, the lead screw 63 drives the slide plate 65 to move, and the slide plate 65 drives the lifting motor 66 and the upright plate 67 to move together. According to the damaged reaction cell, the slide plate 65 is moved to the guide rod 53 below the corresponding reaction cell. At this time, the lifting motor 66 drives the screw 68 to rotate, and the screw 68 drives the lifting frame 69 to extend from the upright plate 67, so that the axis of the arc-shaped opening 691 coincides with the axis of the guide rod 53. The slide plate 65 continues to move, so that the side of the lifting frame 69 is close to the side of the push ring 56 away from the push spring 55. The lifting frame 69 pushes the push ring 56, and the push ring 56 can compress the push spring 55, so that the push spring 55 stores elastic potential energy.

[0049] When the sliding shaft 42 needs to be reset, the lifting frame 69 is retracted into the upright plate 67, which releases the lifting frame 69 from pushing the push ring 56. The reset spring 43 pushes the sliding shaft 42 to reset, and the sliding shaft 42 drives the slide tube 54 to reset through the connecting frame 52. The slide tube 54 pushes the push spring 55 to reset until the rotating plate 223 is drawn out from the through hole 421.

[0050] A mounting frame 8 is provided on the side of the support frame 7 away from the reaction tank 1; the drive mechanism 3 includes a rotary motor 31, a first splined shaft 32, a second splined shaft 33, a sleeve 34, a connecting pipe 35, a connecting plate 36, a driving synchronous pulley 37, a driven synchronous pulley 38, and a synchronous belt 39; the rotary motor 31 is mounted on the top surface of the mounting frame 8, the first splined shaft 32 is coaxially connected to the output shaft of the rotary motor 31, and the first splined shaft 32 is mounted on the top surface of the mounting frame 8 through a bearing support; the second splined shaft 33 is mounted on the top surface of the mounting frame 8 through a bearing support, and the first splined shaft 32 and the second splined shaft 33 are coaxial; the sleeve 34 is sleeved on the first splined shaft 32 and the second splined shaft 33. At the ends of the key shafts 33 that are close to each other, the inner wall of the sleeve 34 is provided with a spline groove 341 for sliding of the first spline shaft 32 and the second spline shaft 33; the end of the first spline shaft 32 is pointed, and the inner wall of the spline groove 341 is chamfered; the inner circumferential surface of the connecting pipe 35 is rotatably connected to the outer circumferential surface of the sleeve 34 through a bearing; one end of the connecting plate 36 is connected to the outer circumferential surface of the connecting pipe 35, and the other end of the connecting plate 36 is connected to the end of the connecting frame 52 away from the semi-circular plate 51; the driving synchronous pulley 37 is coaxially connected to the second spline shaft 33, the driven synchronous pulley 38 is coaxially connected to the rotating shaft 22, and the synchronous belt 39 is wound around the driving synchronous pulley 37 and the driven synchronous pulley 38.

[0051] When it is necessary to drive the rotating shaft 22 to rotate, the rotary motor 31 drives the first spline shaft 32 to rotate. The first spline shaft 32 drives the second spline shaft 33 to rotate through the sleeve 34. The second spline shaft 33 drives the driving synchronous pulley 37 to rotate. The driving synchronous pulley 37 drives the driven synchronous pulley 38 to rotate through the synchronous belt 39. The driven synchronous pulley 38 can then drive the rotating shaft 22 to rotate. When the rotating plate 223 is aligned with the through hole 421, the sliding shaft 42 drives the connecting bracket 52 to move closer to the rotating shaft 22 through the semi-circular arc plate. Recently, the connecting bracket 52 drives the connecting tube 35 to move towards the second spline shaft 33 via the connecting plate 36. The connecting tube 35 drives the sleeve 34 to slide from the first spline shaft 32 to the second spline shaft 33. When the sliding shaft 42 moves to the required position, the first spline shaft 32 slides out of the sleeve 34. This process is very brief. When the positioning groove 2331 is adjusted to face upward, the drive of the rotary motor 31 on the second spline shaft 33 can be immediately released by moving the sleeve 34, thus preventing the continued drive of the rotating shaft 22 to rotate.

[0052] When the slide tube 54 is reset, the slide tube 54 and the Palace Museum drive the connecting plate 36 to reset through the connecting bracket 52. The connecting plate 36 drives the connecting pipe 35 to reset, and the connecting pipe 35 drives the sleeve 34 to reset, so that the first spline shaft 32 is re-inserted into the spline groove 341, and the rotary motor 31 can continue to drive the second spline shaft 33 to rotate.

[0053] The implementation principle of the rotary microbial carrier water pollution purification device in this application embodiment is as follows: The inlet pipe 11 introduces pre-treated wastewater into the reaction tank 1. The drive mechanism 3 drives the rotating shaft 22 to rotate. The rotating shaft 22, through the connected mounting shaft 24, drives the connecting shaft 23 to rotate as well. The rotating shaft 21 also rotates along with the mounting shaft 24. The mounting shaft 24 drives the turntable 25 to rotate within the reaction tank 1. The wastewater sequentially passes through multiple reaction chambers. The lower part of the turntable 25 is immersed in the wastewater. The wastewater flows sequentially through each reaction chamber, gradually degrading pollutants until the final treatment is complete. The wastewater is then discharged to the subsequent process section through the effluent pipe 12. By installing the turntable 25 on an independent mounting shaft 24, and the mounting shaft 24 being detachably connected to the connecting shaft 23, stopping the rotation of the drive shaft 22, removing the damaged turntable 25 mounting shaft 24 from the two adjacent connecting shafts 23, and then installing the undamaged turntable 25 mounting shaft 24 on the two adjacent connecting shafts 23, a quick replacement can be completed without having to remove the entire rotating microbial carrier unit 2 from the reaction tank 1, thus improving the replacement efficiency and further improving the wastewater treatment efficiency.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
