Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically a MABR microbial membrane coupling carrier for wastewater treatment. Background Technology

[0002] Biofilm carriers are a special technology used in wastewater treatment processes. They utilize permeable membranes for aeration and oxygen supply, allowing dissolved oxygen to diffuse into the biofilm and oxidize pollutants. These membranes not only serve as a medium for oxygen transfer but also as a carrier for biofilm growth. In particular, MABR (Multi-Mesh Biofilm Coupling) carriers are a highly efficient and innovative wastewater treatment technology with broad application prospects.

[0003] However, the above technologies often have the following drawbacks: When using traditional MABR microbial membrane coupling carriers, the collected wastewater needs to be introduced into the carrier through the inlet pipe for full reaction. However, since the inlet lacks a filtration device, impurities in the wastewater may clog the water holes on the surface of the distribution pipe, thereby affecting the wastewater treatment efficiency.

[0004] Therefore, the present invention provides a MABR microbial membrane coupling carrier for wastewater treatment. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A MABR (Microbial Biofilm Coupling Carrier) for wastewater treatment, comprising a main body, an air inlet pipe and a water inlet pipe connected through the surface of the main body, a filter device disposed on the surface of the water inlet pipe, the filter device comprising a protective shell, a slot formed on the surface of the protective shell, a filter plate installed in the slot, a cover plate fixedly installed on the surface of the protective shell by bolts, a sealing ring fixedly connected to the surface of the filter plate, and a sealing groove formed on the inner wall of the slot relative to the sealing ring. During operation, wastewater is introduced into the biofilm carrier through the water inlet pipe, and impurities in the wastewater are filtered out by the filter plate, preventing impurities from entering the water distribution pipe and causing blockage. The removable filter plate allows for periodic cleaning and replacement, thus ensuring the filtration effect of the filter device. The sealing ring improves the sealing between the filter plate and the slot.

[0007] Preferably, a crossbar is fixedly connected to the inner wall of the protective shell, and a rotating shaft is rotatably connected inside the crossbar. A fan blade is fixedly connected to one end of the rotating shaft inside the crossbar, and several levers are fixedly connected to the other end. During operation, when sewage passes through the filtration device, the resulting water flow will drive the fan blade to rotate. At the same time, the fan blade will drive the levers to rotate, causing the levers to scrape the filter plate surface and clean the filter plate. Cleaning the filter plate by using the levers can effectively reduce the frequency of filter plate replacement and reduce labor intensity.

[0008] Preferably, the sealing ring is made of rubber and is hollow. An elastic air storage block is fixed inside the filter plate, and an air outlet is connected through the surface of the air storage block. The air storage block communicates with the sealing ring through the air outlet. A top block is fixed inside the slot. During operation, when the filter plate is replaced and inserted into the slot, the top block at the bottom of the slot will squeeze the air storage block, causing the air storage block to contract. At this time, the gas in the air storage block enters the sealing ring through the air outlet, causing the sealing ring to inflate and expand, further improving the sealing effect. When disassembling the filter plate, the cover plate is removed first. Then, the elastic air storage block automatically returns to its original position, squeezing the filter plate upwards for easy replacement by the operator.

[0009] Preferably, the lever is arc-shaped, a support rod is fixedly connected to one side of the lever, a magnetic strip is fixedly connected to the end of the support rod, a recycling box is fixedly connected to the inner wall of the protective shell, the recycling box is mesh-like, an isolation plate is fixedly connected inside the recycling box, a slot is opened on the surface of the recycling box, a rotating plate is rotatably connected inside the slot, and the rotating plate is made of a magnetically attractive material;

[0010] During operation, when the lever scrapes against the surface of the filter plate, the impurities accumulated on the lever surface slide towards the end of the lever due to inertia. Then, after the lever rotates to the slot position, the magnetic strip on one side of the lever attracts the rotating plate, causing the rotating plate to rotate. At this time, the slot opens, and the impurities enter the recovery box under inertia. Since the recovery box is mesh, the rotation of the fan blades will cause the sewage to create a vortex effect, causing the impurities in the recovery box to rotate in a fixed direction and accumulate on the surface of the isolation plate, preventing them from flowing back out. The recovery box collects and stores the impurities in the inlet pipe, further reducing the frequency of filter plate replacement.

[0011] Preferably, the recycling box is annular, and a pressure bar is fixed to the surface of the filter plate.

[0012] Preferably, a diversion pipe is fixedly connected to the surface of the water inlet pipe via a tee pipe. The diversion pipe includes a diversion cover, which functions the same as the filter device. Two diversion devices are provided inside the water inlet pipe. Each diversion device includes a fixing rod, which is fixedly connected to the inner wall of the water inlet pipe. A collar is fixedly connected to the inner wall of the water inlet pipe. A sliding shaft is slidably connected to the surface of the fixing rod via a spring. A plunger is fixedly connected to one end of the sliding shaft. The spring force generated by the spring near the diversion cover of the diversion device is greater than the spring force generated by the spring in the diversion device near the protective shell.

[0013] During operation, when the filter plate becomes clogged, the spring in the diversion device near the protective shell will drive the plunger to gradually move towards the collar. At the same time, the pressure in the inlet pipe gradually increases. At this time, the diversion device near the diversion hood will be pressurized and create a passage, allowing the sewage in the inlet pipe to pass through the filter screen inside the diversion hood and enter the biofilm carrier, achieving the effect of a temporary passage and further improving the sewage treatment efficiency.

[0014] Preferably, a positioning shaft is slidably connected to the fixing rod at the position of the protective shell via a spring. A magnetic block is fixed to the end of the positioning shaft. A magnetic ring is slidably connected to the surface of the water inlet pipe via a spring. A positioning groove is formed on the surface of the sliding shaft relative to the position of the positioning shaft. During operation, due to the pressure reduction of the diversion device on the side near the protective shell, the spring will drive the plunger to fit against the surface of the collar. At the same time, under the action of the positioning shaft spring, the positioning shaft will be inserted into the positioning groove to position the plunger. At this time, by opening the cover, the filter screen inside the protective shell can be cleaned, realizing the function of cleaning the filter screen without stopping the machine.

[0015] Preferably, a sleeve is fixed to the inner wall of the diversion hood, and a solid ball is fixed to the sleeve by a spring. A spring is fixed to the sleeve. The fan blades and the solid ball inside the diversion hood are both magnetic and repel each other. During operation, when sewage is introduced into the diversion hood, the flow of sewage will drive the fan blades inside the diversion hood to rotate. When the fan blades rotate to the position of the solid ball, the solid ball will strike the spring, making a sound to remind the staff to clean the filter plate in the protective shell.

[0016] Preferably, the spring is a cymbal, and a rubber gasket is fixed to the side of the plunger near the collar; during operation, the cymbal can produce a louder sound to alert the operator, and the rubber gasket can improve the sealing of the plunger and prevent water leakage.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The MABR microbial membrane coupling carrier for wastewater treatment described in this invention allows wastewater to be introduced into the biofilm carrier through an inlet pipe. Simultaneously, impurities in the wastewater are filtered out by a filter plate, preventing impurities from entering the distribution pipe and causing blockage. Furthermore, the removable filter plate allows for regular cleaning and replacement, thereby ensuring the filtration effect of the filtration device. The sealing ring improves the sealing between the filter plate and the slot.

[0019] 2. In the MABR microbial membrane coupling carrier for wastewater treatment described in this invention, when the filter plate becomes clogged, the spring in the diversion device near the protective shell will drive the plunger to gradually move towards the collar. At the same time, the pressure in the inlet pipe gradually increases. At this time, the diversion device near the diversion hood will be pressurized to create a passage, allowing the wastewater in the inlet pipe to pass through the filter screen in the diversion hood and enter the biofilm carrier, achieving the effect of a temporary passage and further improving the wastewater treatment efficiency.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1: As Figures 1 to 7 As shown in the embodiment of the present invention, a MABR microbial membrane coupling carrier for wastewater treatment includes a body 1. An air inlet pipe 2 and a water inlet pipe 3 are connected through the surface of the body 1. A filter device 4 is provided on the surface of the water inlet pipe 3. The filter device 4 includes a protective shell 10. A slot 17 is opened on the surface of the protective shell 10. A filter plate 6 is installed in the slot 17. A cover plate 5 is fixedly installed on the surface of the protective shell 10 by bolts. A sealing ring 16 is fixedly connected to the surface of the filter plate 6. A sealing groove is opened on the inner wall of the slot 17 relative to the position of the sealing ring 16.

[0035] During operation, wastewater is introduced into the biofilm carrier through the inlet pipe 3, and impurities in the wastewater are filtered out through the filter plate 6 to prevent impurities from entering the water distribution pipe and causing blockage. The detachable filter plate 6 can be cleaned and replaced regularly to ensure the filtration effect of the filtration device 4. The sealing ring 16 can improve the sealing between the filter plate 6 and the slot 17.

[0036] A crossbar 9 is fixedly connected to the inner wall of the protective shell 10. A rotating shaft is rotatably connected inside the crossbar 9. A fan blade 8 is fixedly connected to one end of the rotating shaft inside the crossbar 9, and several levers 7 are fixedly connected to the other end. During operation, when sewage passes through the filtration device 4, the water flow generated will drive the fan blade 8 to rotate. At the same time, the fan blade 8 will drive the levers 7 to rotate, so that the levers 7 scrape on the surface of the filter plate 6 to clean the filter plate 6. Cleaning the filter plate 6 by using the levers 7 can effectively reduce the replacement frequency of the filter plate 6 and reduce labor intensity.

[0037] The sealing ring 16 is made of rubber and is hollow. An elastic air storage block 13 is fixedly connected inside the filter plate 6. An air outlet 15 is connected through the surface of the air storage block 13. The air storage block 13 is connected to the sealing ring 16 through the air outlet 15. A top block 12 is fixedly connected inside the slot 17.

[0038] During operation, as the filter plate 6 is replaced and inserted into the slot 17, the top block 12 at the bottom of the slot 17 will squeeze the air storage block 13, causing the air storage block 13 to contract. At this time, the gas in the air storage block 13 enters the sealing ring 16 through the air outlet 15, causing the sealing ring 16 to inflate and expand, further improving the sealing effect. When disassembling the filter plate 6, first remove the cover plate 5. Then, the elastic air storage block 13 will automatically return to its original position, squeezing the filter plate 6 upwards, making it convenient for the staff to replace.

[0039] The lever 7 is arc-shaped, and a support rod 19 is fixedly connected to one side of the lever 7. A magnetic strip is fixedly connected to the end of the support rod 19. A recycling box 14 is fixedly connected to the inner wall of the protective shell 10. The recycling box 14 is mesh-like. An isolation plate 18 is fixedly connected inside the recycling box 14. A slot 21 is opened on the surface of the recycling box 14. A rotating plate 20 is rotatably connected inside the slot 21. The rotating plate 20 is made of magnetic material.

[0040] During operation, when the lever 7 scrapes against the surface of the filter plate 6, because the lever 7 is arc-shaped, the impurities accumulated on the surface of the lever 7 will slide towards the end of the lever 7 under the inertial force. Then, after the lever 7 rotates to the position of the slot 21, the magnetic strip on one side of the lever 7 will attract the rotating plate 20, causing the rotating plate 20 to rotate. At this time, the slot 21 opens, and under the action of inertia, the impurities will enter the recovery box 14. Since the recovery box 14 is mesh, when the fan blade 8 rotates, it will cause the sewage to have a vortex effect, causing the impurities in the recovery box 14 to rotate in a fixed direction and accumulate on the surface of the isolation plate 18, without flowing back out. The impurities in the inlet pipe 3 are collected and stored through the recovery box 14, further reducing the replacement frequency of the filter plate 6.

[0041] The recycling box 14 is annular, and a pressure rod 11 is fixed to the surface of the filter plate 6.

[0042] Example 2: Figures 8 to 11As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a diversion pipe 22 is fixedly connected to the surface of the water inlet pipe 3 through a three-way pipe. The diversion pipe 22 includes a diversion cover 30, which has the same function as the filter device 4. Two diversion devices 33 are provided inside the water inlet pipe 3. The diversion device 33 includes a fixing rod 24, which is fixedly connected to the inner wall of the water inlet pipe 3. A collar 28 is fixedly connected to the inner wall of the water inlet pipe 3. A sliding shaft 23 is slidably connected to the surface of the fixing rod 24 through a spring. A plunger 29 is fixedly connected to one end of the sliding shaft 23. The spring force generated by the spring near the diversion cover 30 of the diversion device 33 is greater than the spring force generated by the spring in the diversion device 33 near the protective shell 10.

[0043] During operation, when the filter plate 6 becomes clogged, the spring in the diversion device 33 near the protective shell 10 will drive the plunger 29 to gradually move towards the collar 28. At the same time, the pressure in the inlet pipe 3 gradually increases. At this time, the diversion device 33 near the diversion hood 30 will be pressurized and create a passage, allowing the sewage in the inlet pipe 3 to pass through the filter screen inside the diversion hood 30 and enter the biofilm carrier, achieving the effect of a temporary passage and further improving the sewage treatment efficiency.

[0044] A positioning shaft 25 is slidably connected to the fixing rod 24 at the position of the protective shell 10 via a spring. A magnetic block 27 is fixed to the end of the positioning shaft 25. A magnetic ring 26 is slidably connected to the surface of the water inlet pipe 3 via a spring. A positioning groove is opened on the surface of the sliding shaft 23 relative to the position of the positioning shaft 25. During operation, due to the pressure reduction of the diversion device 33 on the side close to the protective shell 10, the spring will drive the plunger 29 to fit against the surface of the collar 28. At the same time, under the action of the spring of the positioning shaft 25, the positioning shaft 25 is driven into the positioning groove, positioning the plunger 29. At this time, by opening the cover plate 5, the filter screen inside the protective shell 10 can be cleaned, realizing the function of cleaning the filter screen without stopping the machine.

[0045] The inner wall of the diversion hood 30 is fixedly connected to a sleeve 34. A solid ball 31 is fixedly connected to the sleeve 34 by a spring. A spring piece 32 is fixedly connected to the sleeve 34. The fan blade 8 and the solid ball 31 inside the diversion hood 30 are both magnetic and like poles repel each other. When sewage is introduced into the diversion hood 30 during operation, the flow of sewage will drive the fan blade 8 inside the diversion hood 30 to rotate. When the fan blade 8 rotates to the position of the solid ball 31, the solid ball 31 will hit the spring piece 32 and make a sound, reminding the staff to clean the filter plate 6 in the protective shell 10.

[0046] The spring 32 is a cymbal, and a rubber pad is fixed to the side of the plunger 29 near the collar 28. When working, the cymbal can produce a louder sound to remind the operator, and the rubber pad can improve the sealing of the plunger 29 to prevent water leakage.

[0047] Working principle: Wastewater is introduced into the biofilm carrier through the inlet pipe 3, and impurities in the wastewater are filtered out by the filter plate 6 to prevent impurities from entering the water distribution pipe and causing blockage. The detachable filter plate 6 can be cleaned and replaced regularly to ensure the filtration effect of the filtration device 4. The sealing ring 16 can improve the sealing between the filter plate 6 and the slot 17. When wastewater passes through the filtration device 4, the water flow will drive the fan blade 8 to rotate. At the same time, the fan blade 8 will drive the lever 7 to rotate, so that the lever 7 scrapes the surface of the filter plate 6 to clean the filter plate 6. Cleaning the filter plate 6 by using the lever 7 can effectively reduce the replacement frequency of the filter plate 6 and reduce labor intensity.

[0048] As the filter plate 6 is replaced and inserted into the slot 17, the top block 12 at the bottom of the slot 17 will squeeze the air storage block 13, causing the air storage block 13 to contract. At this time, the gas in the air storage block 13 enters the sealing ring 16 through the air outlet 15, causing the sealing ring 16 to inflate and expand, further improving the sealing effect. When disassembling the filter plate 6, first remove the cover plate 5. Then, the elastic air storage block 13 will automatically return to its original position, squeezing the filter plate 6 upwards for easy replacement. When the lever 7 scrapes against the surface of the filter plate 6, because the lever 7 is arc-shaped, the impurities accumulated on the surface of the lever 7 will be removed under inertial force. The impurities will slide towards the end of the lever 7. After the lever 7 rotates to the slot 21 position, the magnetic strip on one side of the lever 7 will attract the rotating plate 20, causing the rotating plate 20 to rotate. At this time, the slot 21 opens, and under the action of inertia, the impurities will enter the recycling box 14. Since the recycling box 14 is mesh, when the fan blade 8 rotates, it will cause the sewage to have a vortex effect, causing the impurities in the recycling box 14 to rotate in a fixed direction and accumulate on the surface of the isolation plate 18. They will not flow out backwards. The impurities in the inlet pipe 3 are collected and stored through the recycling box 14, further reducing the replacement frequency of the filter plate 6.

[0049] When filter plate 6 becomes clogged, the spring in the diversion device 33 near the protective shell 10 will drive the plunger 29 to gradually move towards the collar 28. Simultaneously, the pressure in the inlet pipe 3 gradually increases. At this time, the diversion device 33 near the diversion hood 30 is pressurized, creating a passage. This allows the wastewater in the inlet pipe 3 to pass through the filter screen inside the diversion hood 30 and enter the biofilm carrier, achieving a temporary passage effect and further improving wastewater treatment efficiency. On the side of the diversion device 33 near the protective shell 10, due to the reduced pressure, the spring will drive the plunger 29 to adhere to... The plunger 29 is positioned by the spring of the positioning shaft 25, which is engaged in the positioning groove. The cover plate 5 can be opened to clean the filter screen inside the protective shell 10, thus achieving the function of cleaning the filter screen without stopping the machine. When sewage is introduced into the diversion hood 30, the flow of sewage will drive the fan blade 8 inside the diversion hood 30 to rotate. When the fan blade 8 rotates to the position of the solid ball 31, the solid ball 31 will hit the spring 32 and make a sound, reminding the staff to clean the filter plate 6 in the protective shell 10.
