Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment process for pear vinegar production. Background Art

[0002] Water pollution, wastewater treatment, and its recycling are frequently discussed topics in environmental technology promotion services. The treatment methods for wastewater from pear vinegar production and their application scenarios are discussed. The treatment method primarily involves pretreatment, biological treatment, and advanced treatment. The combined use of these steps effectively removes pollutants, improves water quality, and recycles resources. This treatment method is applicable not only to wastewater from pear vinegar production but also to wastewater treatment in other food processing industries, providing support for environmental protection and sustainable development.

[0003] The biological treatment process requires a certain reaction time, during which wastewater cannot be discharged, affecting the overall efficiency. At the same time, in the early stages of wastewater treatment, blockage and accumulation are common when filtering suspended matter and impurities, making them difficult to clean up. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a wastewater treatment process for duck pear vinegar production to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Through the drive component and transmission coordination, the filtered wastewater is sent to different chambers for waiting, which can avoid secondary pollution and is sent alternately to the biological treatment box. Each time the chamber is switched, the corresponding biofilm filter cartridge will be switched to avoid using a biofilm filter cartridge for a long time, improve the treatment efficiency, reduce the intermediate waiting time, and facilitate the cleaning of impurities accumulated inside the primary treatment box.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solution: a process for treating wastewater from the production of pear vinegar, the treatment process comprising the following steps:

[0006] (1) The wastewater is sent into the filter frame. After the filtration is completed in the filter frame, the filter frame is driven by the drive assembly to rotate and send the wastewater into different chambers of the primary treatment box for storage;

[0007] (2) After each chamber is filtered and filled with water, the water supply is stopped, and the push plate moves along the inside of the filter frame to clean the filter frame. The impurities accumulated on the filter box push plate are sent out from the discharge slots on both sides of the filter frame by the scraper;

[0008] (3) The wastewater is alternately fed into the biological treatment tank through the connecting layer under the rotation of the drive assembly for aerobic wastewater treatment to remove organic matter;

[0009] (4) By cooperating with the drive assembly and the transmission assembly, the biofilm filter cartridge is switched to connect with the delivery pipe, and the wastewater is sent into the biofilm filter cartridge through the delivery pipe, and is discharged from the discharge pipe after deep treatment by the biofilm filter cartridge;

[0010] (5) The biofilm filter cartridge that has rotated to the top can be manually removed from the deep treatment box by opening the top cover and using physical or chemical cleaning methods to clean the organic impurities inside.

[0011] Furthermore, according to the drive assembly described in step (1), the drive assembly includes a drive motor, which drives the first gear to rotate and engage with the gear ring, thereby driving the rotation of the first turntable and the filter assembly, and inputting the wastewater into different chambers in the primary treatment box respectively. The outlet end of the first turntable sends the wastewater into the interior of the biological treatment box through the connecting layer, and the wastewater is intermittently transported and continuously treated.

[0012] Furthermore, according to the movement of the push plate described in step (2), the first screws at the top of both sides of the filter frame rotate, driving the bidirectional screws and the push plate to move from one end of the filter frame to one side of the filter tank, thereby cleaning the impurities inside the filter frame.

[0013] Furthermore, according to the movement of the scraper described in step (2), when the push plate moves to the vicinity of the filter tank, the two screw hole plates and the scraper are driven by the bidirectional electric push rod to move to both sides along the push plate and the back of the filter tank, pushing the impurities on the surface of the filter tank and the push plate surface to the discharge grooves on both sides.

[0014] Furthermore, when the scraper is close to the baffle, the baffle is pushed open by the top column at the upper end of the scraper, and impurities flow out from the discharge trough and the slag discharge trough.

[0015] Furthermore, a slag discharge groove is opened at the bottom of the primary treatment box and the position of the partition corresponding to the discharge groove. Whenever the filter frame rotates, the position of the discharge groove will correspond to the slag discharge groove, so the inside of the filter frame can be cleaned after each water injection is completed.

[0016] Furthermore, according to step (3), the wastewater is sent to the biological treatment box, and a second turntable is fixedly connected to the bottom of the filter frame. As the driving component drives the filter frame to rotate, the gaps of the connecting frame and the first turntable can be alternately matched with different chambers, thereby storing the wastewater in different chambers, and storing the wastewater in the chamber into which the wastewater is injected, and then sending the wastewater into the biological treatment box through the outlet of the second turntable and the connecting layer after the treatment is completed in the biological treatment box.

[0017] Furthermore, according to the transmission assembly described in step (4), the transmission assembly includes a gear ring, the gear ring rotates and engages with the second gear, the second gear rotates synchronously with the first bevel gear, the first bevel gear engages with the second bevel gear, drives the rotation of the rotating shaft, and then switches the biofilm filter cartridge inside the deep treatment box, and maintains synchronous switching with the primary treatment box chamber.

[0018] Furthermore, according to the switching of the biofilm filter cartridge described in step (4), the biofilm filter cartridge is rotatably installed with a rotating shaft, and the rotating shaft rotates to switch the biofilm filter cartridge to dock with the delivery pipe. The biofilm filter cartridge moved to the bottom is pushed by the two-way electric push rod to squeeze contact with the plug block, and the plug block slides forward along the slide groove, and the sealing ring slides synchronously until it squeezes contact with the delivery pipe and the discharge pipe, thereby realizing a sealed connection between the pipeline and the biofilm filter cartridge, deeply treating the wastewater, and removing organic matter in the wastewater.

[0019] Furthermore, according to the removal of the biofilm filter cartridge described in step (5), the biofilm filter cartridge at the upper end of the deep treatment box is also pushed outward by the bidirectional electric push rod, and the remaining plug positions cooperate with the limit plate and the slide groove to form a snap-fit installation. The biofilm filter cartridge at the upper end can be taken out after opening the top cover, and the organic impurities inside can be cleaned by physical or chemical cleaning.

[0020] Beneficial effects of the present invention:

[0021] 1. In the present invention, under the action of the transmission assembly and the drive assembly, the rotating shaft rotates, and the biofilm filter cartridge is switched to dock with the delivery pipe, so as to avoid continuous use of one biofilm filter cartridge, which causes the internal filter holes to be clogged with organic matter. The biofilm filter cartridge moved to the bottom is squeezed into contact with the plug block under the push of the two-way electric push rod. The plug block slides forward along the slide groove, and the sealing ring slides synchronously until it is squeezed into contact with the delivery pipe and the discharge pipe, thereby realizing a sealed connection between the pipeline and the biofilm filter cartridge, deeply treating the wastewater and removing organic matter in the wastewater. At the same time, the biofilm filter cartridge at the upper end is also pushed outward by the two-way electric push rod, and the positions of the remaining plug blocks cooperate with the limit plates and the slide groove to form a snap-on installation. The biofilm filter cartridge at the upper end can be taken out after opening the top cover, and the organic impurities inside can be cleaned by physical or chemical cleaning.

[0022] 2. The wastewater of the present invention enters the filter frame and flows out through one side of the filter tank, and flows into the interior of the chamber composed of two partitions under the guidance of the connecting frame. After each filtration and water injection of a chamber is completed, the water supply is suspended, and the first screw rotates, driving the bidirectional screw and the push plate to move from one end of the filter frame to one side of the filter tank to clean the impurities inside the filter frame. When it moves to the vicinity of the filter tank, the two screw hole plates and the scraper are driven by the bidirectional electric push rod to move to both sides along the push plate and the back of the filter tank, pushing the impurities on the surface of the filter tank and the push plate to the discharge grooves on both sides. When it is close to the baffle position, the baffle is pushed open by the top column at the upper end of the scraper, and the impurities flow out from the discharge groove and the slag discharge groove to avoid accumulation inside the filter frame.

[0023] 3. The present invention is fixedly connected to the bottom of the filter frame through the second turntable. As the driving assembly drives the filter frame to rotate, the gaps of the connecting frame and the first turntable can be alternately matched with different chambers, thereby storing wastewater in different chambers, and storing wastewater in the chamber into which wastewater is injected. After the biological treatment box is processed, the wastewater is sent into the biological treatment box through the outlet of the second turntable and the connecting layer. In this process, the top of the chamber is sealed by the first turntable, which can reduce the re-contamination of wastewater by impurities in the external environment. Whenever the filter frame rotates, the position of the discharge trough will correspond to the slag discharge trough, so the inside of the filter frame can be cleaned after each water injection to avoid the accumulation of impurities.

[0024] 4. The present invention rotates the gear ring to engage with the second gear, the second gear rotates synchronously with the first bevel gear, and the first bevel gear engages with the second bevel gear, thereby driving the rotation of the rotating shaft, thereby switching the biofilm filter cartridge inside the deep treatment box and maintaining synchronous switching with the primary treatment box chamber.

[0025] 5. The present invention drives the first gear to rotate and engage with the gear ring through a driving motor, thereby driving the rotation of the first turntable and the filter assembly, and inputting the wastewater into different chambers in the primary treatment box respectively. The outlet end of the first turntable sends the wastewater into the biological treatment box through the connecting layer, and the wastewater is intermittently transported and continuously treated. In this structure, the biological treatment box is an existing aerobic biological wastewater treatment equipment.

[0026] 6. Compared with the prior art, the present invention sends the filtered wastewater into different chambers for waiting through the cooperation of drive components and transmission, which can avoid secondary pollution and send it into the biological treatment box alternately. Each time the chamber is switched, the corresponding biofilm filter cartridge will be switched to avoid using one biofilm filter cartridge for a long time, improve the treatment efficiency, reduce the intermediate waiting time, and facilitate the cleaning of impurities accumulated inside the primary treatment box.

The first bevel gear 62 is meshed with the second bevel gear 63, driving the rotation of the rotating shaft 64, thereby switching the biofilm filter cartridge 33 inside the deep treatment box 3, and maintaining synchronous switching with the chamber of the primary treatment box 1.

[0049] In this embodiment, the filter assembly 4 also includes a first screw 44, and the first screws 44 are rotatably installed on both sides of the top of the filter frame 41 through a bearing seat and a drive motor. A bidirectional screw 45 is provided between the two first screws 44, and the two ends of the bidirectional screw 45 are threadedly sleeved on the surface of the first screw 44 through the bearing seat. The bottom of the bidirectional screw 45 is connected to a push plate 46, and two scrapers 48 are symmetrically provided on the surface of the push plate 46 facing the side of the connecting frame 42. A screw hole plate 47 is fixed on the top of the scraper 48, and the screw hole plate 47 is threadedly sleeved on the two end surfaces of the bidirectional screw 45. The filter frame 41 faces the connecting frame 42. A filter tank 410 is provided on one side, and a discharge tank is provided on both sides of the filter tank 410. A slag discharge tank 1515 is provided at the position of the discharge tank corresponding to the partition 1414 and the bottom of the primary treatment box 1. The outer end of the discharge tank of the filter frame 41 is connected to a baffle 43 through a spring, and a top column 49 is fixed on the surface of the scraper 48. The wastewater enters the filter frame 41 and flows out through one side of the filter tank 410. Under the guidance of the connecting frame 42, it flows into the chamber composed of the two partitions 1414. After completing the filtration and water injection of a chamber each time, the water supply is suspended, and the first screw 44 rotates, driving the bidirectional screw 45 and the push plate 46 to One end of the filter frame 41 moves toward the side of the filter tank 410 to clean the impurities inside the filter frame 41.

The second turntable 53 is fixedly connected to the bottom of the filter frame 41. As the drive assembly 5 drives the filter frame 41 to rotate The wastewater is stored in different chambers and the wastewater is injected into the chamber for storage. After the wastewater is processed by the biological treatment box 22, it is sent into the biological treatment box 22 through the outlet of the second turntable 53 and the connecting layer 12. In this process, the top of the chamber is sealed by the first turntable 13 to reduce the contamination of the wastewater by impurities in the external environment. Whenever the filter frame 41 rotates, the position of the discharge trough will correspond to the slag discharge trough 1515, so the inside of the filter frame 41 can be cleaned after each water injection to avoid the accumulation of impurities.

[0050] The top of the deep treatment box 3 is provided with a top cover 32 which is rotatable by a hinge. The two ends of the biofilm filter cartridge 33 are slidably sleeved with sealing rings 34, and a return spring 35 is sleeved on the surface of the biofilm filter cartridge 33 at the rear end of the sealing ring 34. The other end of the return spring 35 is fixedly connected to the back of the sealing ring 34. Slide grooves 36 are equidistantly provided on the surface of the rotating shaft 64, and a limit plate 37 is fixed to the middle top of the slide groove 36. An insert 39 is fixed to the bottom of the sealing ring 34, and the insert 39 is slidably inserted into the slide groove 36. Two bidirectional electric push rods 38 are rotatably installed in the middle position of the rotating shaft 64 through the shaft ring, and the bidirectional electric push rods 38 are respectively squeezed and contacted with the insert 39 of the biofilm filter cartridge 33 at the upper and lower ends of the rotating shaft 64. In this structure, the two bidirectional electric push rods 38 are installed inside the deep treatment box 3 and do not rotate with the rotating shaft 64. The filter cartridge 33 is moved to the bottom of the filter housing 33 and is pushed by the two-way electric push rod 38 to squeeze and contact with the plug 39. The plug 39 slides forward along the slide groove 36, and the sealing ring 34 slides synchronously until it is squeezed and contacted with the delivery pipe 21 and the discharge pipe 31, thereby achieving a sealed connection between the pipeline and the biofilm filter cartridge 33, deeply treating the wastewater and removing organic matter in the wastewater. At the same time, the biofilm filter cartridge 33 at the upper end is also pushed by the two-way electric push rod 38 to move the plug 39 outward. The positions of the remaining plugs 39 cooperate with the limit plates 37 and the slide groove 36 to form a snap-fit installation. The biofilm filter cartridge 33 at the upper end can be taken out after opening the top cover 32, and the organic impurities inside can be cleaned by physical or chemical cleaning.

[0051] When the device is in use, the wastewater is sent into the filter frame 41, and the driving motor 51 drives the first gear 52 to rotate and mesh with the gear ring 52, thereby driving the rotation of the first turntable 13 and the filter assembly 4, and respectively inputting the wastewater into different chambers in the primary treatment box 1. The outlet end of the first turntable 13 sends the wastewater into the biological treatment box 22 through the connecting layer 12, and performs intermittent transportation and continuous treatment on the wastewater. The wastewater enters the filter frame 41 and flows out through one side of the filter tank 410, and flows into the chamber composed of two partitions 1414 under the guidance of the connecting frame 42. After each filtration and water injection of a chamber is completed, the water supply is suspended, and the first screw 44 rotates, driving the bidirectional screw 45 and the push plate 46 from one end of the filter frame 41 to the filter tank 410 It moves to one side to clean the impurities inside the filter frame 41. When it moves to the vicinity of the filter tank 410, the two screw hole plates 47 and the scraper 48 are driven to move to both sides along the push plate 46 and the back of the filter tank 410 through the bidirectional electric push rod 38, and the impurities on the surface of the filter tank 410 and the push plate 46 are pushed to the discharge grooves on both sides. When it is close to the baffle 43, the top column 49 at the upper end of the scraper 48 pushes the baffle 43 open, and the impurities flow out from the discharge groove and the slag discharge groove 1515 to avoid accumulation inside the filter frame 41. The second turntable 53 is fixedly connected to the bottom of the filter frame 41. As the drive assembly 5 drives the filter frame 41 to rotate, the notches of the connecting frame 42 and the first turntable 13 can be alternately matched with different chambers, thereby storing the wastewater in different chambers, and The chamber for injecting wastewater stores the wastewater and waits for the biological treatment box 22 to complete the treatment and then send it into the biological treatment box 22 through the outlet of the second turntable 53 and the connecting layer 12. In this process, the first turntable 13 seals the top of the chamber to reduce the re-contamination of wastewater by impurities in the external environment. Whenever the filter frame 41 rotates, the position of the discharge trough will correspond to the slag discharge trough 1515, so the cleaning of the inside of the filter frame 41 can be completed after each water injection to avoid the accumulation of impurities. The gear ring 52 rotates and meshes with the second gear 61, and the second gear 61 rotates synchronously with the first bevel gear 62. The first bevel gear 62 meshes with the second bevel gear 63, driving the rotation of the rotating shaft 64, thereby cutting the biofilm filter cartridge 33 inside the deep treatment box 3. The filter cartridge 33 is switched and kept synchronously switched with the chamber of the primary treatment box 1. Under the action of the transmission assembly 6 and the drive assembly 5, the rotating shaft 64 rotates, switching the biofilm filter cartridge 33 to dock with the delivery pipe 21, avoiding the continuous use of one biofilm filter cartridge 33, which causes the internal filter holes to be blocked by organic matter. The biofilm filter cartridge 33 moved to the bottom is pushed by the two-way electric push rod 38 and squeezed into contact with the plug 39. The plug 39 slides forward along the slide groove 36, and the sealing ring 34 slides synchronously until it is squeezed into contact with the delivery pipe 21 and the discharge pipe 31, thereby realizing a sealed connection between the pipeline and the biofilm filter cartridge 33, deeply treating the wastewater and removing organic matter in the wastewater. At the same time, the biofilm filter cartridge 33 at the upper end is also pushed by the two-way electric push rod 38, and the plug 39 moves outward.The remaining inserts 39 are positioned to form a snap-fit installation with the limit plate 37 and the slide groove 36. The biofilm filter cartridge 33 at the upper end can be removed after opening the top cover 32, and the organic impurities inside can be cleaned by physical or chemical cleaning.
