Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more particularly to a biological ribbon water treatment device with a built-in microbial slow-release carbon source. Background Technology

[0002] Biological ribbons are a commonly used water purification packing material. They provide a carrier for microorganisms to attach to, and the metabolism of these microorganisms removes pollutants from the water. During operation, replenishing the surface of the biological ribbon with carbon sources is an important means to maintain the activity of microorganisms and ensure the treatment effect.

[0003] Currently, the main methods for supplementing carbon sources to bio-ribbons include manual sprinkling and fixed spraying. Manual sprinkling involves frequent operations, and the amount of carbon source added and the spraying location depend on the operator's experience, which can lead to significant differences in the amount of carbon source received by different bio-ribbons. Fixed spraying usually involves continuous spraying, with the carbon source mainly acting on one side of the bio-ribbon, and the other side having less opportunity to come into contact with the carbon source. At the same time, the coverage area of ​​fixed nozzles is small, resulting in poor adhesion of the carbon source to the surface of the bio-ribbon. Therefore, it is necessary to provide a bio-ribbon water treatment device with built-in microbial slow-release carbon source to solve the above technical problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a biological ribbon water treatment device with its own microbial slow-release carbon source.

[0007] The spraying unit is used to extract liquid carbon source from the carbon source box and spray the extracted liquid carbon source onto the nearby bio-ribbon assembly; the bio-ribbon assembly can switch working postures on the movement path under the guidance of the guide component.

[0008] The intermittent drive unit is used to drive the ribbon component to move intermittently, so that the biological ribbon assembly stops sequentially and receives spray from the spray unit.

[0009] Preferably, the biological ribbon assembly includes a fixing base, which is fixedly connected to the outside of the first synchronous belt. A fixing rod is vertically and rotatably connected through the fixing base. A connecting frame is fixedly connected to the bottom end of the fixing rod.

[0012] Preferably, the push-pull component includes a horizontal slide rod, with the other end of the liquid inlet cylinder slidably connected to the horizontal slide rod through it. A piston is slidably and sealed inside the liquid inlet cylinder. One end of the horizontal slide rod extends into the liquid inlet cylinder and is fixedly connected to one side of the piston. The other end of the horizontal slide rod is rotatably connected to one end of a hinge rod. A fixing frame is fixedly connected to the top of the mounting plate. A motor is fixedly mounted on the top of the fixing frame. A disc is fixedly sleeved on the rotating end of the motor. An eccentric shaft is fixedly connected to the bottom of the disc. The eccentric shaft is eccentrically fixed to the bottom of the disc. The other end of the hinge rod is rotatably sleeved on the eccentric shaft.

[0013] Preferably, the swing component includes a sliding bar, one end of which is fixedly connected to the side wall of the horizontal sliding rod, the sliding bar is slidably connected to the mounting plate, and the other end of the sliding bar is rotatably connected to a first vertical rotating wheel. A fixing bar is fixedly connected to the outer side of the horizontal tube section of one of the L-shaped tubes, and a long slot is vertically opened on the fixing bar. The first vertical rotating wheel is rotatably disposed in the long slot.

[0014] Preferably, the intermittent drive unit includes an intermittent control component and a transmission component; the intermittent control component includes a toggle disc, which is fixedly sleeved on the outside of the rotating end of the motor. The outer circumferential surface of the toggle disc is provided with an outer arc surface. A toggle bar is fixedly connected to the bottom of the toggle disc, and a toggle post is fixedly connected to the top of the toggle bar. A first concave arc surface is formed on the outer circumferential surface of the toggle disc. A vertical rotating shaft is rotatably connected to the top of the mounting plate.

A plurality of long grooves are formed at equal intervals along the circumferential direction on the outer circumferential surface of the transmission disc.

[0015] Preferably, the transmission component includes a second synchronous pulley, which is fixedly sleeved on the outside of the vertical rotating shaft. The top end of one of the first synchronous pulleys is fixedly connected to a third synchronous pulley, and the outer sides of the second and third synchronous pulleys are jointly sleeved with a second synchronous belt.

[0016] Preferably, the bottom of the mounting plate is fixedly connected to a plurality of horizontal rotating shafts that are equidistant along its length, and two support wheels are symmetrically rotatably connected to both ends of the horizontal rotating shafts. The support wheels are rolled at the bottom of the first synchronous belt.

[0017] Preferably, the actuating post is matched with the long groove.

[0018] Compared with related technologies, the biological ribbon water treatment device with built-in microbial slow-release carbon source provided by the present invention has the following beneficial effects:

[0019] 1. This invention uses the intermittent drive unit to drive the first synchronous belt in the ribbon component to move intermittently through the cooperation of the actuating disc and the transmission disc. This causes the biological ribbon components, which are equidistantly arranged outside the first synchronous belt, to stop sequentially within the working area of ​​the spraying unit during movement. Simultaneously, the spraying unit uses a carbon source box to store external liquid carbon source. A piston is driven to reciprocate within the liquid inlet cylinder through a push-pull component, cooperating with the first and second one-way valves to complete the intake and discharge of the carbon source. By using the intermittent drive unit to make the biological ribbon components stop sequentially to receive spray from the spraying unit, compared to the continuous movement spraying method, each group of biological ribbons obtains a basically consistent spraying residence time. This device helps to reduce the problem of short carbon source spraying residence time caused by continuous movement, thereby improving the carbon source adhesion effect.

[0020] 2. In this invention, a horizontal rack is fixedly connected to the outside of the mounting plate. When the bio-ribbon assembly moves to the other side of the mounting plate along with the first synchronous belt, the gear rotatably connected to the fixed base contacts and meshes with the horizontal rack. The gear drives the fixed rod, the connecting frame at the bottom of the fixed rod, and the bio-ribbon to rotate 180°. After the second vertical rotating wheel moves out of the straight guide groove, the coil spring installed in the mounting groove at the bottom of the fixed base releases the accumulated elastic potential energy, assisting the fixed rod and the bio-ribbon to tend to return to their initial posture. At the same time, one side of the horizontal bar abuts against the limiting stop bar again, jointly achieving reset positioning. This design allows carbon source to be sprayed onto both sides of each bio-ribbon via two L-shaped pipes symmetrically arranged on both sides of the mounting plate and their nozzles. This achieves directional carbon source spraying on both sides of the bio-ribbon, increasing the amount of carbon source attached to the bio-ribbon. Compared to single-sided spraying, the guide component guides the bio-ribbon to rotate 180° during movement, allowing both sides of the bio-ribbon to receive carbon source spraying sequentially. Under the same spraying conditions, this increases the carbon source load per unit length of bio-ribbon, thus providing a more sufficient nutrient substrate for microorganisms.

[0021] 3. In this invention, during the reciprocating motion of the horizontal sliding rod of the push-pull component, it drives the sliding strip fixedly connected to its side wall to move synchronously. The first vertical rotating wheel, which is rotatably connected to one end of the sliding strip, rolls in the long slot of the fixed strip, thereby pushing the fixed strip and the L-shaped tube to swing back and forth around the axis of the vertical cylinder. This causes the liquid carbon source sprayed from the nozzle to dynamically sweep across the vicinity of the biological ribbon surface of the biological ribbon assembly in a stationary state. Compared with the fixed nozzle, the swinging spray can expand the spray coverage of a single set of nozzles and reduce the carbon source spray blind zone.

[0022] 4. This invention uses a single motor that can simultaneously drive the push-pull component of the injection unit and the intermittent control component of the intermittent drive unit under rated operating conditions. This enables the extraction, pressurization, and injection of the liquid carbon source, as well as the intermittent movement, attitude flipping, and reset of the biological ribbon assembly to be performed in a coordinated manner. This reduces the amount of manual carbon replenishment and manual flipping of the biological ribbon, thereby reducing the intensity of operation and maintenance.

[0023] 5. In this invention, multiple horizontal rotating shafts are equidistantly arranged at the bottom of the mounting plate along the length direction. Each horizontal rotating shaft has two support wheels symmetrically connected to its two ends. The support wheels are rolled at the bottom of the first synchronous belt. The multiple support wheels work together to effectively support the first synchronous belt. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] Example 1

[0039] Please refer to the following: Figures 1 to 9 A biological ribbon water treatment device with a self-contained microbial slow-release carbon source includes an installation plate 1, a carbon source box 2 fixedly installed on the top of the installation plate 1, and a spray unit 3, a ribbon switching unit 4 and an intermittent drive unit 5 installed on the installation plate 1.

[0040] The ribbon switching unit 4 includes a ribbon component 41 and a guide component 42. The ribbon component 41 includes a first synchronous pulley 411. Four first synchronous pulleys 411 are symmetrically rotatably connected on both sides of the bottom of the mounting plate 1. A first synchronous belt 412 is connected to the four first synchronous pulleys 411 for transmission. Several biological ribbon components are arranged at equal intervals on the outer side of the first synchronous belt 412.

[0041] The spraying unit 3 is used to extract liquid carbon source from the carbon source box 2 and spray the extracted liquid carbon source onto the nearby biological ribbon assembly, so that the liquid carbon source is adsorbed on the surface of the biological ribbon 4110 to form a carbon source attachment layer. This attachment layer can gradually release carbon source in the water, providing a continuous nutrient supply for the microorganisms attached to the biological ribbon 4110. The biological ribbon assembly can switch working postures on the movement path under the guidance of the guide component 42.

[0042] The intermittent drive unit 5 is used to drive the ribbon component 41 to move intermittently, so that the biological ribbon assembly stops in sequence and receives spray from the spray unit 3.

[0043] In the above-mentioned process, the ribbon component 41 in the ribbon switching unit 4 drives multiple biological ribbon assemblies to move cyclically via the first synchronous pulley 411 and the first synchronous belt 412. The guide component 42 guides the biological ribbon assemblies to switch working postures along the movement path, thereby realizing the directional flipping or resetting of the biological ribbon 4110. The spraying unit 3 is responsible for extracting liquid carbon source from the carbon source box 2 and spraying it onto the biological ribbon assembly located in the spraying area, so that the liquid carbon source is adsorbed on the surface of the biological ribbon 4110 to form a slow-release carbon source attachment layer. This attachment layer can slowly release carbon source in the water for attachment. The continuous utilization of microorganisms on the biological ribbon 4110 helps maintain the metabolic activity of microorganisms on the surface of the biological ribbon 4110, providing a guarantee for improving the water purification effect. The intermittent drive unit 5 drives the ribbon component 41 to make intermittent movements, so that each biological ribbon component can stop in turn in the working area of ​​the spray unit 3, so that each biological ribbon component can obtain approximately equal carbon source spraying time. Through the coordinated cooperation of the above units, the device can automatically and continuously replenish carbon sources for multiple sets of biological ribbons 4110, reducing manual intervention and improving the uniformity and efficiency of carbon source attachment.

[0044] Furthermore, the biological ribbon assembly includes a fixing base 413, which is fixedly connected to the outside of the first synchronous belt 412. A fixing rod 414 is vertically and rotatably connected through the fixing base 413. A connecting frame 415 is fixedly connected to the bottom end of the fixing rod 414. Two biological ribbons 4110 are symmetrically fixedly connected to both sides of the connecting frame 415. A gear 416 is fixedly sleeved on the upper outer side of the fixing rod 414. A horizontal bar 417 is fixedly connected to the top end of the fixing rod 414. One end of the horizontal bar 417 is rotatably connected to... The second vertical rotating wheel 418 is eccentrically arranged with the fixed rod 414. A limit stop 419 is fixedly connected to the outer wall of the fixed seat 413. One side of the horizontal bar 417 abuts against one side of the limit stop 419. The bottom of the fixed seat 413 is provided with an installation groove. A coil spring 4111 is provided in the installation groove. One end of the coil spring 4111 is fixedly connected to the outer wall of the fixed rod 414, and the other end of the coil spring 4111 is fixedly connected to the inner wall of the installation groove. The first synchronous belt 412 and the first synchronous pulley 411 mesh and drive each other.

[0045] In the above, when gear 416 is driven to rotate by an external force, fixed rod 414 drives biological ribbon 4110 to rotate. During the rotation, coil spring 4111 accumulates elastic potential energy. After the external force disappears, coil spring 4111 releases elastic potential energy, which can cause fixed rod 414 to rotate in the opposite direction and reset, thereby driving biological ribbon 4110 to return to its initial posture. At the same time, crossbar 417 and limit stop bar 419 re-abut. The first synchronous belt 412 meshes with the first synchronous pulley 411 to ensure the synchronicity of biological ribbon assembly moving with the first synchronous belt 412. This design provides a reliable mechanical basis for the 180° rotation of biological ribbon 4110 and realizes automatic reset without additional power.

[0046] Furthermore, the guide component 42 includes a horizontal guide rail 421, which is fixedly mounted on the mounting plate 1. A straight guide groove 422 is provided at the bottom of the horizontal guide rail 421. The straight guide groove 422 is parallel to one side of the first synchronous belt 412. A horizontal rack 423 is fixedly connected to the outside of the mounting plate 1. The meshing stroke length of the horizontal rack 423 and the gear 416 is equal to half the circumference of the pitch circle of the gear 416. The starting point of the straight guide groove 422 is located directly downstream of the meshing end point of the horizontal rack 423. The inlet of the straight guide groove 422 can be provided with a chamfer or flared structure. When the gear 416 contacts the horizontal rack 423, they mesh, driving the fixed rod 414 and the biological ribbon 4110 to rotate 180°, realizing the switching of the posture of the biological ribbon 4110 on both sides.

[0047] In the above, after the biological ribbon assembly completes its flip, the second vertical wheel 418 enters the straight guide groove 422 and rolls along its inner wall, guiding the biological ribbon 4110 to maintain its flipped posture and continue moving, preventing it from deflecting due to external force or vibration during movement. The guide component 42 cooperates with the gear 416 of the biological ribbon assembly and the second vertical wheel 418 to realize the automatic double-sided switching of the biological ribbon 4110 on the movement path without the need for additional drive components.

[0048] Example 2

[0049] For further details, please refer to [link / reference]. Figures 1 to 10Based on Embodiment 1, the spraying unit 3 includes a spraying component 31, a push-pull component 32, and a swinging component 33. The spraying component 31 includes an inlet cylinder 311, which is fixedly connected to the top of the mounting plate 1. One end of the inlet cylinder 311 is connected to an inlet pipe 312 and an outlet pipe 313, respectively. The other end of the inlet cylinder 311 has a vent hole 3111. A first one-way valve 318 is installed in the inlet pipe 312, and a second one-way valve 319 is installed in the outlet pipe 313. One end of the inlet pipe 312 is connected to the bottom outlet end of the carbon source box 2, and one end of the outlet pipe 313 is connected to a rotary connector. The head 314 has a rotating joint 314 connected to a vertical cylinder 315 at one end. The vertical cylinder 315 is vertically rotatably connected to the mounting plate 1. Two L-shaped tubes 316 are symmetrically connected to the bottom of the vertical cylinder 315. Several nozzles 317 connected to the interior of the vertical tube 316 are fixedly connected at equal intervals from top to bottom on one side of the vertical tube section of the L-shaped tube 316. The nozzles 317 on the two L-shaped tubes 316 are symmetrically arranged and face opposite directions. When the biological ribbon 4110 stops on one side, it receives spray from the nozzles 317 on one side of the L-shaped tube 316. When it stops on the other side after flipping, it receives spray from the nozzles 317 on the other side of the L-shaped tube 316.

[0050] In the above-mentioned process, during the reciprocating motion of the piston 322 in the liquid inlet cylinder 311, when the first one-way valve 318 is opened, the carbon source is drawn into the liquid inlet cylinder 311 through the liquid inlet pipe 312. When the second one-way valve 319 is opened, the carbon source passes through the liquid outlet pipe 313, the rotary joint 314, the vertical cylinder 315 and the L-shaped pipe 316 in sequence and is then sprayed out from the nozzles 317 on both sides. The symmetrical and oppositely oriented nozzles 317 can spray the front and back sides of the biological ribbon 4110 respectively. With the flipping action of the biological ribbon 4110, the carbon source is attached to both sides. The rotary joint 314 allows the vertical cylinder 315 and the L-shaped pipe 316 to swing during the spraying process, thereby expanding the spray coverage area.

[0051] Furthermore, the push-pull component 32 includes a horizontal slide rod 321. The other end of the liquid inlet cylinder 311 is slidably connected to the horizontal slide rod 321. A piston 322 is slidably and sealed inside the liquid inlet cylinder 311. One end of the horizontal slide rod 321 extends into the liquid inlet cylinder 311 and is fixedly connected to one side of the piston 322. The other end of the horizontal slide rod 321 is rotatably connected to one end of the hinge rod 323. A fixing frame 324 is fixedly connected to the top of the mounting plate 1. A motor 325 is fixedly installed on the top of the fixing frame 324. A disc 326 is fixedly sleeved on the rotating end of the motor 325. An eccentric shaft 327 is fixedly connected to the bottom of the disc 326. The eccentric shaft 327 is eccentrically fixed to the bottom of the disc 326. The other end of the hinge rod 323 is rotatably sleeved on the eccentric shaft 327.

[0052] In the above, when the motor 325 drives the disc 326 to rotate continuously, the eccentric shaft 327 drives the horizontal slide bar 321 and the piston 322 to reciprocate linearly within the liquid inlet cylinder 311 via the hinge rod 323. The push-pull component 32 converts the rotational motion of the motor 325 into the reciprocating motion of the piston 322, thereby periodically changing the volume inside the liquid inlet cylinder 311. In conjunction with the opening and closing of the first one-way valve 318 and the second one-way valve 319, the intake and pressurized discharge of the liquid carbon source are realized. Since the stroke of the piston 322 is determined by the eccentricity of the eccentric shaft 327, the volume of carbon source discharged in each reciprocating motion is relatively fixed, thereby realizing the control of the injection volume, which is beneficial to ensure that the amount of carbon source received by each biological ribbon 4110 is closer. At the same time, the reciprocating motion of the horizontal slide bar 321 can also synchronously drive the swing component 33 to achieve the effect of one power for multiple outputs.

[0053] Furthermore, the swing component 33 includes a sliding bar 331. One end of the sliding bar 331 is fixedly connected to the side wall of the horizontal sliding rod 321. The sliding bar 331 is slidably connected to the mounting plate 1. The sliding direction of the sliding bar 331 is consistent with the movement direction of the horizontal sliding rod 321. The other end of the sliding bar 331 is rotatably connected to a first vertical rotating wheel 332. A fixing bar 333 is fixedly connected to the outer side of the horizontal tube section of an L-shaped tube 316. A long slot 334 is vertically opened through the fixing bar 333. The first vertical rotating wheel 332 is rotatably disposed in the long slot 334.

[0054] In the above, when the horizontal sliding rod 321 reciprocates under the drive of the push-pull component 32, the sliding bar 331 drives the first vertical rotating wheel 332 to reciprocate synchronously. Since the first vertical rotating wheel 332 rolls in the long slot 334, and the long slot 334 is opened on the fixed bar 333, and the fixed bar 333 is fixedly connected to the L-shaped tube 316, the linear motion of the first vertical rotating wheel 332 will push the fixed bar 333 and the L-shaped tube 316 to swing back and forth around the axis of the vertical cylinder 315. When the L-shaped tube 316 swings, the nozzle 317 on the L-shaped tube 316 also swings, so that the sprayed liquid carbon source forms a dynamic sweeping effect near the surface of the biological ribbon 4110. Compared with the fixed nozzle 317, the swinging component 33 expands the effective spray coverage of a single set of nozzles 317, which helps the carbon source to adhere more widely to the surface of the biological ribbon 4110 and reduces the spray blind zone.

[0055] Example 3

[0056] For further details, please refer to [link / reference]. Figures 1 to 12Based on Embodiment 2, the intermittent drive unit 5 includes an intermittent control component 51 and a transmission component 52; the intermittent control component 51 includes a toggle disc 511, which is fixedly sleeved on the outside of the rotating end of the motor 325. The outer peripheral surface of the toggle disc 511 is provided with an outer arc surface 512. A toggle bar 514 is fixedly connected to the bottom of the toggle disc 511, and a toggle post 515 is fixedly connected to the top of the toggle bar 514. The outer peripheral surface of the toggle disc 511 is provided with a first concave arc surface 513. The top of the mounting plate 1 rotates. A vertical rotating shaft 516 is connected, and a transmission disk 517 is fixedly sleeved on the outer side of the vertical rotating shaft 516. Several long grooves 518 are equally spaced along the circumferential direction on the outer circumferential surface of the transmission disk 517. A second concave arc surface 519 is provided between two adjacent long grooves 518 on the circumferential surface of the transmission disk 517. The first concave arc surface 513 is located on the rotation path of the actuating column 515 and is used to avoid the transmission disk 517 when the actuating column 515 is disengaged from the long groove 518. The actuating column 515 matches the long groove 518.

[0057] In the above, when the motor 325 drives the actuating disk 511 to rotate continuously, the actuating column 515 enters the long groove 518 and pushes the transmission disk 517 to rotate through a certain angle. Then, the outer arc surface 512 and the second concave arc surface 519 fit together to keep the transmission disk 517 stationary. This cycle is repeated to achieve the intermittent rotation of the transmission disk 517. The intermittent control component 51 only needs one motor 325 to generate intermittent motion output, providing a stable power source for the intermittent movement of the ribbon component 41 and ensuring that the biological ribbon assembly has sufficient residence time in the spray area.

[0058] Furthermore, the transmission component 52 includes a second synchronous pulley 521, which is fixedly sleeved on the outside of the vertical rotating shaft 516. The top end of one of the first synchronous pulleys 411 is fixedly connected to a third synchronous pulley 522. The outer sides of the second synchronous pulley 521 and the third synchronous pulley 522 are jointly sleeved with a second synchronous belt 523. Both the second synchronous pulley 521 and the third synchronous pulley 522 mesh with the second synchronous belt 523 for transmission.

[0059] In the above, when the vertical rotating shaft 516 rotates intermittently with the transmission disc 517, the second synchronous pulley 521 drives the third synchronous pulley 522 to rotate intermittently through the second synchronous belt 523, which in turn drives the first synchronous pulley 411 connected to it to rotate intermittently, ultimately enabling the first synchronous belt 412 and the biological ribbon assembly on its outer side to move intermittently. The transmission component 52 adopts a synchronous belt transmission method, which can ensure accurate transmission ratio and synchronization, avoid slippage, and match the moving position of each biological ribbon assembly with the working sequence of the spraying unit 3.

[0060] Furthermore, the bottom of the mounting plate 1 is fixedly connected with several horizontal rotating shafts 6 that are equidistant along its length. The two ends of the horizontal rotating shafts 6 are symmetrically connected to two support wheels 7. The bottom of the first synchronous belt 412 is smooth, and the support wheels 7 are rolled at the bottom of the first synchronous belt 412.

[0061] In the above, the support wheel 7 effectively lifts the bottom of the first synchronous belt 412 through rolling contact, reducing the sag of the first synchronous belt 412 and keeping the first synchronous belt 412 on a relatively straight motion trajectory, thereby improving the positional stability of the biological ribbon assembly during movement and pause.

[0062] Furthermore, the motor 325 is electrically connected to an external control switch via a wire, and the operating state of the motor 325 is controlled by the external control switch.

[0063] The working principle of the biological ribbon water treatment device with built-in microbial slow-release carbon source provided by this invention is as follows:

[0064] The mounting plate 1 is fixedly installed on the external support carrier, so that the biological ribbon 4110 is immersed in the water to be treated and the first synchronous belt 412 is positioned above the water surface. The liquid carbon source is stored in the carbon source box 2. When in use, the motor 325 is started, and the rotating end of the motor 325 simultaneously drives the disc 326 and the actuating disc 511 to rotate.

[0065] Motor 325 drives disk 326 to rotate. Eccentric shaft 327 at the bottom of disk 326 pushes horizontal slide bar 321 in reciprocating motion via hinge rod 323. Horizontal slide bar 321 drives piston 322 to reciprocate and slide within inlet cylinder 311. When piston 322 moves outward, i.e., away from inlet pipe 312, the first one-way valve 318 opens and the second one-way valve 319 closes, creating a negative pressure within inlet cylinder 311. Liquid carbon source from carbon source box 2 is drawn into inlet cylinder 311 through inlet pipe 312 and the first one-way valve 318. When piston 322 moves inward, i.e., closer to inlet pipe 312, the second one-way valve 319 opens and the first one-way valve 318 closes, allowing liquid to flow into inlet cylinder 311. The liquid carbon source inside is pressurized and forced into the rotary joint 314 through the second one-way valve 319 and the outlet pipe 313. Then it enters the vertical cylinder 315 and the two L-shaped tubes 316 in sequence, and finally sprays out from the nozzles 317 of the two L-shaped tubes 316. At the same time, the horizontal slide bar 321 drives the sliding bar 331 to move synchronously. The sliding bar 331 drives the first vertical rotating wheel 332 to move back and forth. The first vertical rotating wheel 332 rolls in the long slot 334 of the fixed bar 333, thereby pushing the fixed bar 333 and the L-shaped tubes 316 to swing back and forth around the axis of the vertical cylinder 315. This expands the spray range of the nozzle 317 to a certain extent compared with the fixed method, thus helping the carbon source to fall more near the biological ribbon 4110 that has moved to the current position.

[0066] Motor 325 simultaneously drives the actuation disk 511 to rotate. As the actuation disk 511 rotates, the actuation pin 515 enters the long groove 518 of the transmission disk 517, pushing the transmission disk 517 to rotate at a certain angle. The first concave arc surface 513 is used to avoid the transmission disk 517. Subsequently, the outer arc surface 512 of the actuation disk 511 is in contact with the second concave arc surface 519 of the transmission disk 517, keeping the transmission disk 517 stationary. This cycle is repeated to achieve intermittent rotation of the transmission disk 517. The transmission disk 517 drives the coaxial vertical rotating shaft 516 and the second synchronous pulley 521 to rotate intermittently. The second synchronous pulley 521 drives the third synchronous pulley 522 to rotate intermittently through the second synchronous belt 523. The third synchronous pulley 522 drives one of the first synchronous pulleys 411 to rotate intermittently, thereby causing the first synchronous belt 412 and the biological ribbon assembly on its outer side to move intermittently. The bottom of the first synchronous belt 412 is supported by the support wheel 7 to ensure smooth movement.

[0067] When the biological ribbon assembly moves with the first synchronous belt 412, when a certain biological ribbon assembly moves to a position opposite to the nozzle 317 of the L-shaped tube 316 on one side of the mounting plate 1, the first synchronous belt 412 enters an intermittent pause state. During the entire pause period, the nozzle 317 continuously sprays carbon source onto the biological ribbon 4110. As the first synchronous belt 412 continues to move intermittently, the biological ribbon assembly that has received the spray gradually moves to the other side.

[0068] When the bio-ribbon assembly moves to the other side of the mounting plate 1, the gear 416 on the fixing seat 413 contacts and begins to mesh with the horizontal rack 423. The gear 416 drives the fixing rod 414 to rotate 180°, and the fixing rod 414 drives the connecting frame 415 and the bio-ribbon 4110 to rotate 180°. At the same time, the horizontal bar 417 at the top of the fixing rod 414 drives the second vertical wheel 418 to rotate to correspond with the straight guide groove 422 at the bottom of the horizontal guide rail 421. In subsequent movements, the second vertical wheel 418 rolls along the straight guide groove 422, guiding the bio-ribbon 4110 to maintain its flipped posture. The coil spring 411... 1. During the flipping process, elastic potential energy is accumulated to provide force for subsequent reset. After flipping, the biological ribbon 4110 continues to move to the vicinity of the nozzle 317 of the L-shaped tube 316 on the other side, so that the other side of the biological ribbon 4110 receives carbon source spraying, so that both sides of the biological ribbon 4110 receive carbon source spraying, improving the overall carbon source adhesion effect. When the second vertical rotating wheel 418 moves out of the straight guide groove 422, the elastic potential energy of the coil spring 4111 is released, causing the fixing rod 414 and the biological ribbon 4110 to return to the initial posture. At the same time, one side of the horizontal bar 417 re-abuts against the limiting stop bar 419.

[0069] Through the coordinated operation of the intermittent drive and spray, each group of biological ribbons 4110 can complete the carbon source attachment process in sequence and continuously immerse themselves in the water, providing continuous nutrition for the microorganisms attached to the surface of the biological ribbons 4110. Through the metabolic action of the microorganisms, pollutants in the water are degraded, thus ensuring the improvement of water purification effect.
