Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a deep treatment device for rosin resin processing wastewater based on microbial community enhancement. Background Technology

[0002] Rosin resin wastewater originates from the production process of rosin, turpentine, and their further processed products. Its composition is complex, classifying it as typical high-concentration, recalcitrant organic industrial wastewater. Rosin resin wastewater is primarily generated during processes such as rosin dissolution, washing, clarification, distillation, workshop rinsing, and rosin storage and maintenance. The wastewater contains a large amount of organic matter, mainly including resin acids, terpenes, and other organic compounds. Early research and practice primarily employed physicochemical methods for treatment. For example, lime was used to neutralize acidic wastewater, followed by comprehensive treatment using methods such as polyferric sulfate coagulation and sedimentation, slag or lignite adsorption, and calcium hypochlorite oxidation. These methods have some effect on COD removal, but are often costly and difficult to achieve stable discharge compliance.

[0003] A coking wastewater deep treatment device, with announcement number CN118894595B, includes an aerobic tank. A horizontal shaft is installed along the water flow direction within the aerobic tank. Multiple coaxial turntables are spaced apart on the shaft. The turntables are hollow, with perforated surfaces, and filled with culture media. A screw is installed at the bottom inner side of the aerobic tank, parallel to the shaft. The ends of the shaft and screw extend out of the aerobic tank, and the exiting ends of the shaft and screw are connected via a drive connection. A sludge discharge pipe is installed at the bottom sidewall of the aerobic tank. A vertical scraper is installed at the bottom inner side of the aerobic tank, with screw holes on the scraper. The screw mates with the screw holes.

[0004] In the aforementioned application documents, although the rotating disc in the aerobic tank can promote the collision and peeling of the bacterial film by rotating, the addition of special bacteria is carried out in a one-time or intermittent external addition method, which results in uneven distribution of the bacterial agent in the tank and the existence of "dead zones". The newly added bacterial agent needs a long time to fully contact and react with the rosin resin processing wastewater, and there is a lack of a continuous and uniform bacterial source replenishment mechanism. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a deep treatment device for rosin resin processing wastewater based on microbial community enhancement. This solves the problems mentioned in the background technology, where the addition of specific bacteria is done in a one-time or intermittent external manner, resulting in uneven distribution of the bacteria within the tank and the existence of "dead zones." Furthermore, newly added bacteria require a long time to fully contact and react with the rosin resin processing wastewater, and there is a lack of continuous and uniform replenishment of the bacterial source. The invention avoids the uneven distribution of bacteria within the tank and the existence of "dead zones" caused by the one-time or intermittent external addition of specific bacteria through the use of a rotary spray device.

[0006] To achieve the above objectives, the present invention provides a deep treatment device for rosin resin processing wastewater based on microbial community enhancement, comprising an aerobic tank, a motor being installed on the right side of the aerobic tank, a rotary jetting device being assembled in the middle of the aerobic tank, the rotary jetting device including a connecting plate fixedly connected to the output shaft of the motor, a hollow rotating tube fixedly connected to the left side of the connecting plate, a rotary joint being rotatably connected to the end of the hollow rotating tube away from the connecting plate, an L-shaped connecting pipe fixedly connected to the left side of the rotary joint, a feeding chamber fixedly connected to the top of the L-shaped connecting pipe, an interface being provided on the left side of the feeding chamber, a spring being fixedly connected to the inner wall of the feeding chamber, an extrusion plate being fixedly connected to the end of the spring being away from the feeding chamber, a handle being fixedly installed on the top of the extrusion plate, a hollow blade being assembled in the middle of the hollow rotating tube, a connecting rod being fixedly installed in the middle of the inner wall of the hollow blade, a spring being fixedly installed at the bottom of the connecting rod, a blocking block being fixedly installed at the end of the spring being away from the connecting rod, and a limit rod being fixedly installed at the bottom of the connecting rod.

[0007] Preferably, an outlet pipe is provided on the right side of the aerobic tank, and an inlet pipe is provided on the left side of the aerobic tank.

[0008] Preferably, the number of hollow blades is nine, and they are evenly distributed in three rows along the circumference of the hollow rotating tube, with three blades evenly distributed in each row along the axial direction.

[0009] Preferably, the hollow blade has a first through hole at the bottom, which matches the block, and the block has a second through hole in the middle, which matches the limiting rod.

[0010] Preferably, the hollow rotating tube is equipped with a rotating stirring device on its outer side for rotating and stirring the interior of the aerobic tank.

[0011] Preferably, the rotary stirring device includes a connecting block mounted on the outside of the hollow rotating tube, a fixing rod fixedly installed at the bottom of the connecting block, a hollow rotating cylinder mounted at the bottom of the fixing rod, a stirring rod mounted on the outside of the hollow rotating cylinder, a bevel gear one mounted at the bottom of the hollow rotating cylinder, an mounting plate fixedly installed at the bottom of the fixing rod, a rotating shaft rotatably connected through the middle of the mounting plate, a bevel gear two mounted on the left side of the rotating shaft, and a roller mounted on the right side of the rotating shaft.

[0012] Preferably, the inner wall of the aerobic tank is semi-circular, the roller matches the inner wall of the aerobic tank, and the first bevel gear and the second bevel gear mesh with each other.

[0013] Preferably, the back of the aerobic tank is equipped with a cleaning device for cleaning impurities floating on the surface of the aerobic tank.

[0014] Preferably, the cleaning device includes a second motor mounted on the front of the aerobic tank and a collection chamber fixedly mounted on the back of the aerobic tank. The output shaft of the second motor is fixedly connected to a lead screw. A moving block is mounted on the left side of the lead screw, and a scraper is fixedly connected to the right side of the moving block. A third spring is fixedly connected to the inner wall of the collection chamber. A scraper is fixedly connected to the end of the third spring away from the collection chamber. A first sliding plate is slidably connected to the back of the collection chamber. A first pull handle is provided on the front of the first sliding plate. A second sliding plate is located at the bottom of the collection chamber, and a second pull handle is provided at the bottom of the second sliding plate.

[0015] Preferably, the movable block is slidably connected to the aerobic tank, the movable block has an internal thread that meshes with the external thread of the lead screw, the scraper is triangular, and the bottom of the scraper is located on the inclined surface of the scraper.

[0016] The advantages of this application are: (1) In this application, a motor drives the hollow rotating tube and hollow paddle to rotate. The extrusion plate in the dosing chamber continuously pushes the special bacterial agent into the L-shaped connecting pipe under the action of the spring. After passing through the rotary joint, it enters the hollow rotating tube and flows into the hollow paddle. The hollow paddle is subjected to centrifugal force, which causes the block to open the perforation outward, and the bacterial agent is evenly sprayed into the wastewater. After the machine stops, the centrifugal force disappears, and the block automatically closes the perforation under the action of the spring, avoiding accidental dosing. This avoids the problem of uneven distribution of the bacterial agent in the pool and the existence of "dead zones" caused by the one-time or intermittent external dosing method for adding special bacteria.

[0017] (2) In this application, when the hollow rotating tube rotates, the connecting block drives the fixed rod and the mounting plate to rotate around the axis. The roller rolls tightly against the semi-circular inner wall of the aerobic tank, causing the rotating shaft to rotate. Through the bevel gear transmission, the hollow rotating cylinder and the stirring rod rotate around their own axis, forming multi-directional fluid movement in the tank. This effectively promotes full contact and mixing between the bacterial agent and the wastewater, significantly improving the reaction efficiency, thereby eliminating the "dead zone" that may exist in traditional stirring and accelerating the biochemical reaction process.

[0018] (3) In this application, the starting motor drives the lead screw to rotate, and the moving block drives the triangular scraper to slide along the pool wall, pushing the foam, suspended solids and other impurities accumulated on the wastewater surface towards the collection chamber. Under the action of the spring, the scraper adheres tightly to the inclined surface of the scraper, peeling off the impurities and guiding them into the collection chamber for storage. After cleaning, the sliding plate resets and seals the collection chamber to prevent impurities from flowing back in when the wastewater is stirred. Before wastewater treatment, floating impurities are effectively removed from the liquid surface to avoid interfering with subsequent bacterial agent addition and biochemical reactions, thereby enhancing the treatment effect.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] Example 1, as Figures 1-5As shown, a deep treatment device for rosin resin processing wastewater based on microbial community enhancement includes an aerobic tank 100. An outlet pipe 400 is located on the right side of the aerobic tank 100 for discharging treated rosin resin processing wastewater. An inlet pipe 300 is located on the left side of the aerobic tank 100 for introducing the rosin resin processing wastewater to be treated into the aerobic tank 100. A motor 200 is located on the right side of the aerobic tank 100. A rotary jet device 500 is assembled in the middle of the aerobic tank 100. The rotary jet device 500 includes a connecting plate 501 fixedly connected to the output shaft of the motor 200. The left side of the connecting plate 501 is fixedly connected to... A hollow rotating tube 502 has an internal cavity for conveying the special bacterial agent. A rotary joint 503 is rotatably connected to the end of the hollow rotating tube 502 away from the connecting plate 501. The rotary joint 503 ensures a continuous supply of the special bacterial agent during rotation. An L-shaped connecting tube 504 is fixedly connected to the left side of the rotary joint 503. A dispensing chamber 505 is fixedly connected to the top of the L-shaped connecting tube 504. The dispensing chamber 505 is used to store the special bacterial agent. An interface 514 is provided on the left side of the dispensing chamber 505 for easy replenishment of the special bacterial agent. A spring 506 is fixedly connected to the inner wall of the dispensing chamber 505. The spring 506 is located away from the dispensing chamber 505. One end is fixedly connected to an extrusion plate 507, and a handle 508 is fixedly installed on the top of the extrusion plate 507 for easy adjustment of its position. A hollow impeller 509 is fitted in the middle of the hollow rotating tube 502. There are nine hollow impellers 509, evenly distributed in three rows along the circumference of the hollow rotating tube 502, with three impellers evenly distributed along the axial direction in each row. This layout ensures that the mixing range covers most of the aerobic tank 100, improving mixing uniformity. A perforation is provided at the bottom of each hollow impeller 509. A connecting rod 510 is fixedly installed in the middle of the inner wall of each hollow impeller 509. A spring 511 is fixedly installed at the bottom of the connecting rod 510. A plug 512 is fixedly installed at the end of the connecting rod 510 away from the second 511. The first through hole matches the plug 512. Under normal conditions, the plug 512 is closed by spring pressure. When the centrifugal force increases, the plug 512 can be pushed open to release the special bactericidal agent. A limit rod 513 is fixedly installed at the bottom of the connecting rod 510. A second through hole is opened in the middle of the plug 512. The second through hole matches the limit rod 513. The limit rod 513 and the second through hole adopt a clearance fit. The diameter of the limit rod 513 is much smaller than the diameter of the first through hole. The limit rod 513 guides the movement trajectory of the plug 512 to prevent it from deviating or falling off, and ensures the stability of the spray control.

[0023] In practical use, the rosin resin processing wastewater enters the aerobic tank 100 through the inlet pipe 300. The motor 200 is started, and its output shaft drives the connecting plate 501 to rotate. The connecting plate 501 drives the hollow rotating tube 502 to rotate, which in turn drives the hollow paddle 509 to rotate. At this time, the extrusion plate 507 in the dosing chamber 505, under the elastic force of the spring 506, continuously pushes the special bacterial agent towards the L-shaped connecting pipe 504. The bacterial agent enters the hollow rotating tube 502 through the rotary joint 503 and then flows into the hollow paddle 509. As the hollow rotating tube 502 rotates, the hollow paddle 509 is subjected to centrifugal force, the spring 511 is stretched, the block 512 moves outward along the limiting rod 513, and the perforation opens. The bacterial agent is then evenly sprayed from the perforation at the bottom of the hollow paddle 509 into the wastewater in the aerobic tank 100, achieving continuous and uniform addition of the bacterial agent. After the special bacterial agent in the dosing chamber 505 has been completely added, pull the handle 508 to move the extrusion plate 507 upward, and replenish the special bacterial agent in the dosing chamber 505 through the interface 514. At this time, the motor 200 stops rotating, the centrifugal force of the hollow blade 509 disappears, and the block 512 retracts inward along the limit rod 513 under the elastic action of the spring 511, blocking the perforation and preventing accidental addition of bacterial agent during non-dosing stages, thus preventing waste.

[0024] Example 2, as Figures 6-7 As shown, based on Embodiment 1, a rotary stirring device 600 for rotating and stirring the interior of the aerobic tank 100 is assembled on the outside of the hollow rotary tube 502. The rotary stirring device 600 includes a connecting block 601 assembled on the outside of the hollow rotary tube 502. A fixing rod 602 is fixedly installed at the bottom of the connecting block 601. A hollow rotary cylinder 603 is assembled at the bottom of the fixing rod 602. A stirring rod 604 is assembled on the outside of the hollow rotary cylinder 603 for effectively stirring the liquid medium in the aerobic tank 100 during rotation. A bevel gear 605 is assembled at the bottom of the hollow rotary cylinder 603. An mounting plate 606 is fixedly installed at the bottom of the fixing rod 602. The middle of the mounting plate 606 is through and... A rotating shaft 607 is rotatably connected. A second bevel gear 608 is mounted on the left side of the rotating shaft 607. The first bevel gear 605 and the second bevel gear 608 mesh with each other, thereby converting the rotational motion of the hollow rotating cylinder 603 into the lateral rotation of the rotating shaft 607. A roller 609 is mounted on the right side of the rotating shaft 607. The inner wall of the aerobic tank 100 is semi-circular. The surface of the inner wall of the aerobic tank 100 is pre-treated. A layer of wear-resistant material with a high coefficient of friction is coated on the semi-circular track area of ​​the inner wall of the aerobic tank 100. The outer periphery of the roller 609 is covered with a friction layer of the same material. The roller 609 matches the inner wall of the aerobic tank 100 to ensure that the roller 609 generates power by rotating itself during rotation.

[0025] In practical use, the above-mentioned equipment is operated by motor 200, which drives the hollow rotating tube 502 to rotate. As the hollow rotating tube 502 rotates, the connecting block 601, fixed to its outer wall, moves in a circular motion around the hollow rotating tube 502. The rotation of the connecting block 601 further drives the fixed rod 602 to rotate synchronously. The fixed rod 602 drives the hollow rotating cylinder 603 and the mounting plate 606 to rotate around the axis of the hollow rotating tube 502. The rotation of the mounting plate 606 causes the rotating shaft 607 mounted on it to rotate, thereby driving the bevel gear 608 fixed at one end of the rotating shaft 607 and the roller 609 at the other end to rotate together. While rotating, the roller 609 rolls against the semi-circular inner wall of the aerobic tank 100, and the rotating shaft 607 rotates due to friction. The rotation of the rotating shaft 607 drives the second bevel gear 608 at its end to rotate. The second bevel gear 608 meshes with the first bevel gear 605 fixed on the stirring rod 604, thereby driving the first bevel gear 605 to rotate. The rotation of the first bevel gear 605 drives the hollow rotating cylinder 603 to rotate around its own axis. The stirring rods 604, which are evenly arranged on the outer wall of the hollow rotating cylinder 603, rotate accordingly, forming multi-directional fluid movement within the aerobic tank 100. This effectively promotes full contact and mixing between the bacterial agent and the wastewater, significantly improving reaction efficiency, thereby eliminating the "dead zone" that may exist in traditional stirring and accelerating the biochemical reaction process.

[0026] Example 3, as Figures 8-10As shown, based on Embodiment 2, the back of the aerobic tank 100 is equipped with a cleaning device 700 for cleaning impurities floating on the surface of the aerobic tank 100. The cleaning device 700 includes a motor 701 disposed on the front of the aerobic tank 100 and a collection chamber 705 fixedly installed on the back of the aerobic tank 100. The output shaft of the motor 701 is fixedly connected to a lead screw 702. A moving block 703 is mounted on the left side of the lead screw 702. The moving block 703 is slidably connected to the aerobic tank 100. The moving block 703 has an internal thread, which meshes with the external thread of the lead screw 702. Thus, when the motor 701 drives the lead screw 702 to rotate, the moving block 703 can move left and right along the axial direction of the lead screw 702. A scraper 704 is fixedly connected to the right side of the moving block 703. The scraper 704 is triangular, with its inclined surface facing the collection chamber 705. It is used to scrape and push impurities during movement. A spring 706 is fixedly connected to the inner wall of the collection chamber 705. A scraper 707 is fixedly connected to the end of the spring 706 away from the collection chamber 705. The bottom of the scraper 707 is located on the inclined surface of the scraper 704. When the scraper 704 moves with the moving block 703 to the vicinity of the collection chamber 705, its inclined surface will push the scraper 707, causing the scraper 707 to compress the spring 706 and lift upward, so that the impurities can smoothly enter the collection chamber 705. A sliding plate 708 is slidably connected to the back of the collection chamber 705. A pull handle 709 is provided on the front of the sliding plate 708, which makes it easy for the operator to pull out the sliding plate 708 by pulling the handle 709 to access and remove the impurities accumulated in the collection chamber 705. In addition, the bottom slide plate 710 of the collection chamber 705 is equipped with a pull handle 711 at the bottom. By pulling the handle 711, the slide plate 710 can be opened so that the collected impurities can be discharged from the bottom or cleaned and maintained.

[0027] When using the above equipment, before activating the rotary jetting device 500 and the rotary stirring device 600 to deeply treat the rosin resin processing wastewater, it is essential to first clean the floating impurities on the surface of the aerobic tank 100 to ensure the subsequent treatment effect. The operator pulls handle 709 to remove the sliding plate 708 from the side wall of the aerobic tank 100, opening the cleaning channel. Then, motor 701 is started, its output shaft driving the lead screw 702 to rotate clockwise, causing the moving block 703 to slide smoothly along the inner wall of the aerobic tank 100 via threaded transmission. The scraper 704 fixed to the moving block 703 moves accordingly, gradually pushing the accumulated foam, suspended solids, and other impurities on the wastewater surface towards the collection chamber 705 located at the end of the tank. A scraper 707 is installed at the inlet of the collection chamber 705. When the scraper block 704 moves towards the collection chamber 705 with the moving block 703, the inclined surface of the scraper block 704 gradually approaches the bottom of the scraper 707. At the moment of contact, the scraper 707 is lifted by the inclined surface and slides along it. At this time, the scraper 707 maintains contact with the inclined surface under the elastic force of the spring 706, thereby scraping off the impurities attached to the surface of the scraper block 704. When the scraper block 704 moves in the opposite direction, the inclined surface of the scraper block 704 disengages from the bottom of the scraper 707, and the scraper 707 returns to its initial position under the action of the spring 706, without creating resistance to the return stroke of the scraper block 704. This ensures that impurities are effectively collected and prevents them from falling back into the wastewater. After the surface impurities are cleaned, the operator pulls the handle 709 again, causing the slide plate 708 to reset and close the opening, thus sealing the collection chamber 705. This step is crucial to prevent the rotary jetting device 500 and rotary agitator 600 from experiencing agitation due to violent stirring of the wastewater during operation, which could cause impurities or wastewater to backflow into the collection chamber 705, affecting the cleaning effect and equipment operational stability. Subsequently, by pulling handle 711 to remove slide plate 710, the accumulated impurities in the collection chamber 705 can be easily cleaned for centralized disposal. After completing the above cleaning operations, the rotary jetting device 500 and rotary agitator 600 can be safely started. The rotary jetting device 500 injects air or chemicals into the wastewater to enhance the oxidation reaction, while the rotary agitator 600 promotes mixing and mass transfer through stirring. Together, they perform advanced wastewater treatment. The treated wastewater quality is significantly improved and is ultimately discharged from the aerobic tank 100 through the effluent pipe 400, achieving stable and compliant discharge that meets environmental protection requirements.
