Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water pollution treatment, in particular to an ecological base for water pollution treatment. BACKGROUND

[0002] Water pollution treatment is a comprehensive prevention and control measure for improving water quality through systematic means. Its core goals include pollutant reduction, water ecological restoration, and long-term management mechanism construction. By eliminating high-pollution enterprises, delineating livestock and poultry restricted areas, and constructing sewage treatment facilities, pollutant emissions are reduced from the source. By using ecological base and constructed wetland technologies, water biodiversity is restored, and water self-purification capacity is enhanced. Through the establishment of a river length management system, a pollution discharge permit system, and environmental law enforcement strengthening, a complete chain of "source control-process treatment-end supervision" is formed.

[0003] An ecological base is a new type of artificial water quality restoration and maintenance method. Its essence is a specially treated biological carrier (filler) that combines materials science, microbiology, and water ecology. It is made of materials with high specific surface area and high load. When the ecological base is placed in water, it quickly adsorbs aquatic organisms and attaches microorganisms, forming a complex ecosystem. These microorganisms decompose organic matter in water through metabolic action and convert nitrogen, phosphorus, sulfur, and other nutrients into harmless substances such as carbon dioxide, water, or nitrogen gas, thereby reducing the nutrient supply required for blue-green algae reproduction and gradually improving water quality. This technology operates in a purely ecological manner, has a lasting effect, enhances water self-purification capacity, and is easy to implement with low maintenance costs.

[0004] In the ecological system of the ecological base, the outer layer of the biological carrier (filler) directly contacts the oxygen-containing water body, with a high oxygen concentration that meets the metabolic needs of aerobic microorganisms. Aerobic microorganisms are mainly distributed in the outer layer of the biological carrier (filler). Ammonia-oxidizing bacteria (such as Nitrosomonas) and nitrite-oxidizing bacteria (such as Nitrobacter) oxidize ammonia to nitrite and then to nitrate under aerobic conditions. This process consists of two steps: nitrosation and nitrification. The inner layer of the biological carrier (filler) is limited by oxygen diffusion, forming an anoxic or anaerobic environment that provides a living space for anaerobic microorganisms. Anaerobic microorganisms are mainly distributed in the inner layer of the biological carrier (filler). Pseudomonas and Bacillus reduce nitrate to gaseous nitrogen under anoxic conditions. This process is called denitrification, and nitrogen gas is ultimately generated and released into the atmosphere, completing the nitrogen cycle.

[0005] Currently, during the use of ecological substrate carriers, under the action of water flow, soil impurities in the water continuously come into contact with the surface of the ecological substrate carrier. Some soil impurities continue to flow under the action of water flow, while some soil impurities easily adhere to the surface of the ecological substrate carrier. The adhesion of soil impurities will gradually block the pores of the ecological substrate carrier, hindering the exchange of substances between the water body and the ecological substrate. The obstruction of substance exchange will affect the metabolic activities of microorganisms in the ecological substrate, thereby reducing the degradation efficiency of pollutants. Harmful substances in the water body cannot be removed in a timely and effective manner, leading to the continuous deterioration of water quality and affecting the effect of water pollution control. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an ecological base for water pollution treatment, which can effectively solve the problems in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an ecological base for water pollution treatment, comprising: A placement platform, the top of which is fixedly connected to a placement rack, the top of which is fixedly connected to a placement box, the inside of which is fixedly connected to a rectangular frame, and the placement box is fixedly connected to an outer layer filler plate and an inner layer filler plate through the rectangular frame respectively. A sliding rod is fixedly connected to the outer surface of the placement rack, and a reciprocating lead screw is rotatably connected to the outer surface of the placement rack. A slider is slidably sleeved on the outer circumference of the sliding rod, and the slider is threaded onto the outer circumference of the reciprocating lead screw.

An adjusting wheel is rotatably connected to one end of the scraping folding strip, and a pressing wheel is rotatably connected to the other end of the scraping folding strip. An adjusting guide rail is fixedly connected to the outer surface of the placement box, and the adjusting wheel is slidably connected inside the adjusting guide rail.

[0008] Furthermore, a square water pipe is fixedly connected inside the placement rack, a short pipe is fixedly connected to the top of the square water pipe, the top of the short pipe is fixedly connected to the bottom of the placement box, a long pipe is fixedly connected to the top of the square water pipe, a connecting cylinder is fixedly connected to the outer surface of the placement box, the top of the long pipe is fixedly connected to the bottom of the connecting cylinder, a rotating ring is rotatably connected to the inner wall of the connecting cylinder, a shaft is fixedly connected to the inner wall of the rotating ring, and a spiral blade is fixedly connected to the outer circumference of the shaft.

[0009] Furthermore, a first gear is fixedly connected to the top end of the reciprocating lead screw, and a second gear is fixedly connected to the top end of the shaft. A transmission toothed belt meshes between the first gear and the second gear.

[0010] Furthermore, a guide cylinder is fixedly connected to the inner wall of the placement box, a guide rod is slidably connected inside the guide cylinder, and a sealing plate is fixedly connected to the end of the guide rod away from the guide cylinder.

[0011] Furthermore, a rotating block is rotatably connected to the inner wall of the placement box, an elliptical guide rail is fixedly connected to the outer circumference of the rotating block, and a push wheel is rotatably connected to the outer surface of the sealing plate, the push wheel being slidably connected inside the elliptical guide rail.

[0012] Furthermore, one end of the rotating block penetrates the side wall of the placement box and is sequentially fixedly connected to a third gear and a limiting block. A lifting rod is slidably connected to the outer surface of the placement box. Teeth are provided on the outer surface of the lifting rod. A limiting strip is fixedly connected to the outer surface of the lifting rod.

[0013] Furthermore, the inner wall of the placement box is fixedly connected to a telescopic element, the telescopic end of the telescopic element is fixedly connected to a push frame, the outer surface of the push frame is fixedly connected to a square frame, the outer surface of the square frame is provided with an inclined rail, the outer surface of the lifting rod is rotatably connected to a lifting wheel, and the lifting wheel is slidably connected inside the inclined rail.

[0014] Furthermore, the telescopic element includes a telescopic cylinder and a telescopic rod. The telescopic cylinder is fixedly connected to the inner wall of the placement box, and the telescopic rod is slidably connected inside the telescopic cylinder. A telescopic spring is fixedly connected between the telescopic rod and the telescopic cylinder, and one end of the telescopic rod passes through the side wall of the placement box and is fixedly connected to the push frame.

[0015] Furthermore, a push lever is fixedly connected to the outer surface of the push frame.

[0016] Furthermore, a drive motor is fixedly connected inside the placement platform, and the output shaft of the drive motor is fixedly connected to the bottom end of the reciprocating lead screw.

[0017] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention utilizes a reciprocating screw to drive a scraping bar to move up and down along a slide bar. During the downward movement of the scraping bar, it adheres tightly to the outer surface of the outer packing plate. The moving scraping bar removes the mud and impurities adhering to the surface of the outer packing plate, preventing the adhering mud and impurities from hindering the exchange of substances between the water and the outer and inner packing plates. This promotes the reproduction and metabolism of microorganisms inside the outer and inner packing plates, thereby accelerating the degradation and transformation of pollutants. As a result, harmful substances in the water are removed in a timely and effective manner, significantly improving water quality.

[0018] 2. This invention uses rotating spiral blades inside the connecting cylinder. The spiral blades drive water through the outer and inner packing plates sequentially into the center of the placement box. From the center of the placement box, the water flows sequentially through a short pipe, a square pipe, and a long pipe into the connecting cylinder. Finally, the water is discharged from the inside of the connecting cylinder through the top opening. This flowing water causes the nitrite and nitrate generated by the microorganisms inside the outer packing plate to move towards the inner packing plate. Firstly, this flow pattern avoids excessive accumulation of nitrate inside the outer packing plate, preventing high concentrations of nitrate from interfering with the uptake of ammonia nitrogen by nitrifying bacteria and promoting the metabolic efficiency of nitrifying bacteria. Secondly, after the nitrate-containing water flows into the inner packing plate, it is utilized by denitrifying bacteria, ultimately generating harmless nitrogen gas, completing the complete removal of nitrogen, forming a continuous "nitrification-denitrification" reaction chain, and further improving the overall nitrogen removal efficiency.

[0019] 3. This invention uses multiple sets of sealing plates inside the placement box that close together and close to each other. After closure, these sealing plates form a tortuous "flow channel" between the outer and inner packing plates. As the water flows along this tortuous "flow channel," it can flow evenly across all areas of both the outer and inner packing plates. This improves the overall nitrate transfer efficiency within the outer packing plate, preventing excessively high nitrate concentrations in certain areas. Furthermore, it enhances the metabolic products of denitrifying bacteria within the inner packing plate, further improving overall denitrification efficiency and enhancing wastewater treatment effectiveness.

[0020] 4. This invention, by setting the water body to flow along the aforementioned tortuous "channel," results in a significantly longer actual flow path than a straight distance. The tortuous "channel" increases the contact area between the water body and the channel wall, thus enhancing friction. This friction consumes the kinetic energy of the water flow, reducing its velocity and consequently decreasing the movement speed of nitrates within the inner packing plate. This extends the residence time of nutrients such as nitrates within the inner packing plate, allowing the microorganisms inside the inner packing plate to fully absorb and utilize the nutrients in the water. This further improves the degradation and transformation efficiency of pollutants in wastewater, ensuring effective water pollution control. Attached Figure Description

[0025] The present invention will be further described below with reference to embodiments. Example 1:

[0026] Please see Figures 1-17 This invention provides a technical solution: an ecological base for water pollution treatment, comprising: Placement platform 1, placement rack 11 is fixedly connected to the top of placement platform 1, placement box 12 is fixedly connected to the top of placement rack 11, rectangular frame 13 is fixedly connected inside placement box 12, and outer layer filler plate 14 and inner layer filler plate 15 are fixedly connected to placement box 12 through rectangular frame 13 respectively.

A spiral blade 36 is fixedly connected to the outer circumference of the shaft 35.

[0028] A first gear 41 is fixedly connected to the top end of the reciprocating lead screw 21, and a second gear 42 is fixedly connected to the top end of the shaft 35. A transmission toothed belt 4 meshes between the first gear 41 and the second gear 42.

[0029] A guide cylinder 5 is fixedly connected to the inner wall of the placement box 12. A guide rod 51 is slidably connected inside the guide cylinder 5. A sealing plate 52 is fixedly connected to the end of the guide rod 51 away from the guide cylinder 5.

[0030] A rotating block 6 is rotatably connected to the inner wall of the placement box 12. An elliptical guide rail 61 is fixedly connected to the outer circumference of the rotating block 6. A push wheel 62 is rotatably connected to the outer surface of the sealing plate 52. The push wheel 62 is slidably connected inside the elliptical guide rail 61.

[0031] One end of the rotating block 6 passes through the side wall of the placement box 12 and is fixedly connected to the third gear 7 and the limiting block 71 in sequence. The outer surface of the placement box 12 is slidably connected to the lifting rod 72. The outer surface of the lifting rod 72 is provided with teeth 73, and the outer surface of the lifting rod 72 is fixedly connected to the limiting strip 74.

[0032] The inner wall of the placement box 12 is fixedly connected to a telescopic element 8, the telescopic end of the telescopic element 8 is fixedly connected to a push frame 81, the outer surface of the push frame 81 is fixedly connected to a square frame 82, the outer surface of the square frame 82 is provided with a sloping rail 83, the outer surface of the lifting rod 72 is rotatably connected to a lifting wheel 84, and the lifting wheel 84 is slidably connected inside the sloping rail 83.

[0033] The telescopic element 8 includes a telescopic cylinder and a telescopic rod. The telescopic cylinder is fixedly connected to the inner wall of the placement box 12, and the telescopic rod is slidably connected inside the telescopic cylinder. A telescopic spring is fixedly connected between the telescopic rod and the telescopic cylinder. One end of the telescopic rod passes through the side wall of the placement box 12 and is fixedly connected to the push frame 81.

[0034] A push lever 9 is fixedly connected to the outer surface of the push frame 81.

[0035] A drive motor is fixedly connected inside the placement platform 1, and the output shaft of the drive motor is fixedly connected to the bottom end of the reciprocating lead screw 21.

[0036] Working principle: Sludge removal technology: In practical applications, by activating the drive motor inside the placement platform 1, the drive motor drives the reciprocating lead screw 21 to rotate around its own axis on the placement frame 11 via the output shaft, as shown below. Figure 8 As shown, under the limiting action of the slide bar 2, the rotating reciprocating screw 21 drives the slider 22 on its outer circumference to move vertically downward along the axis of the slide bar 2, as... Figure 9 and Figure 10As shown, the slider 22 drives the scraping fold 24 inside the rectangular groove 23 to move downwards. During this process, one end of the scraping fold 24 is rotatably connected to an adjusting wheel 25. The adjusting wheel 25 slides downwards along the vertical section of the adjusting guide rail 26 (the vertical section near the placement box 12), so that the scraping fold 24 cannot slide along the inner wall of the rectangular groove 23 (the scraping fold 24 and the slider 22 remain relatively stationary). The scraping fold 24 moves vertically downwards against the outer surface of the outer packing plate 14. As the slider 22 and the scraping fold 24 continue to move downwards, the scraping fold 24 drives the adjusting wheel 25 at one end to slide along the vertical section of the adjusting guide rail 26 (the vertical section near the placement box 12) and connect it to the arc-shaped section at the bottom of the adjusting guide rail 26. Under the limiting action of the arc-shaped section at the bottom of the guide rail 26, the adjusting wheel 25 drives the scraping folding strip 24 to gradually move away from the outer packing plate 14 along the inner wall of the rectangular groove 23. When the adjusting wheel 25 moves to the middle position of the arc-shaped section at the bottom of the adjusting guide rail 26, the rotating reciprocating screw 21 immediately drives the slider 22 to move vertically upward along the axis of the slide rod 2. The slider 22 drives the scraping folding strip 24 to move upward through the rectangular groove 23. The scraping folding strip 24 drives the adjusting wheel 25 at one end to slide upward along the arc-shaped section of the adjusting guide rail 26. Under the limiting action of the arc-shaped section of the adjusting guide rail 26, the adjusting wheel 25 continues to drive the scraping folding strip 24 to gradually move away from the outer packing plate 14 along the inner wall of the rectangular groove 23. As the slider 22 and the scraping folding strip 24 continue to move upward... As the sliding progresses, the scraping fold 24 drives the adjusting wheel 25 at one end of the scraping fold 24 to slide along the arc-shaped section of the adjusting guide 26 and connect with the vertical section (the vertical section away from the placement box 12) of the adjusting guide 26. Under the limiting action of the vertical section (the vertical section away from the placement box 12) of the adjusting guide 26, the scraping fold 24 cannot slide along the inner wall of the rectangular groove 23 (the scraping fold 24 and the slider 22 remain relatively stationary). During this process, the scraping fold 24 separates from the outer packing plate 14. As the slider 22 and the scraping fold 24 continue to move upward, the scraping fold 24 drives the adjusting wheel 25 at one end of the scraping fold 24 to slide along the vertical section (the vertical section away from the placement box 12) of the adjusting guide 26 and connect with the arc-shaped section at the top of the adjusting guide 26. Under the limiting action of the top arc-shaped section, the adjusting wheel 25 drives the scraping folding strip 24 to gradually approach the outer packing plate 14 along the inner wall of the rectangular groove 23. When the adjusting wheel 25 moves to the middle position of the top arc-shaped section of the adjusting guide rail 26, the rotating reciprocating screw 21 immediately drives the slider 22 to move vertically downward along the axis of the slide rod 2. The slider 22 drives the scraping folding strip 24 downward through the rectangular groove 23. The scraping folding strip 24 drives the adjusting wheel 25 at one end to slide downward along the arc-shaped section of the adjusting guide rail 26. Under the limiting action of the arc-shaped section of the adjusting guide rail 26, the adjusting wheel 25 continues to drive the scraping folding strip 24 to gradually approach the outer packing plate 14 along the inner wall of the rectangular groove 23. As the slider 22 and the scraping folding strip 24 continue to move downward,The scraping folding bar 24 drives the adjusting wheel 25 at one end to slide along the arc section of the adjusting guide rail 26 and connect with the vertical section of the adjusting guide rail 26 (the vertical section near the placement box 12). In this way, by controlling the reciprocating screw 21 to continuously rotate on the placement frame 11, the slider 22 and the scraping folding bar 24 reciprocate up and down. During the downward movement of the scraping folding bar 24, it adheres tightly to the outer surface of the outer packing plate 14. The moving scraping folding bar 24 scrapes away the mud and impurities adhering to the surface of the outer packing plate 14, preventing the adhering mud and impurities from hindering the exchange of substances between the water and the outer and inner packing plates 14 and 15. This promotes the reproduction and metabolism of microorganisms inside the outer and inner packing plates 14 and 15, thereby accelerating the degradation and transformation of pollutants, ensuring the timely and effective removal of harmful substances from the water, and significantly improving water quality.

[0037] Water circulation technology: In practical applications, such as Figure 2 and Figure 3 As shown, during the rotation of the placement frame 11, the reciprocating screw 21 drives the first gear 41 at its top to rotate around its own axis. Under the transmission action of the transmission belt 4, the rotating first gear 41 drives the second gear 42 to rotate around the axis of the second gear 42 via the transmission belt 4. Figure 4 As shown, the rotating second gear 42 drives its bottom shaft 35 to rotate around its own axis. The rotating shaft 35 drives the helical blades 36 on its outer circumference to rotate inside the connecting cylinder 33 around the axis of the connecting cylinder 33. In this process, combined with... Figure 5 , Figure 6 and Figure 7It can be seen that during the rotation of the spiral blade 36 inside the connecting cylinder 33, the surface of the spiral blade 36 exerts an upward thrust on the water inside the connecting cylinder 33, accelerating the flow of the water inside the connecting cylinder 33. Since the bottom of the connecting cylinder 33 is fixedly connected to the square water pipe 3 via the long pipe 32, and the top of the square water pipe 3 is fixedly connected to the placement box 12 via the short pipe 31, it can be seen that as the spiral blade 36 continues to rotate, the rotating spiral blade 36 drives the flowing water to pass through the outer packing plate 14 and the inner packing plate 15 in sequence and enter the center of the placement box 12. The flowing water then flows from the center of the placement box 12 in sequence along the short pipe 31, the square water pipe 3, and the long pipe 32 into the connecting cylinder 33. Finally, the flowing water exits from the connecting cylinder 33. The water is discharged from the inside of the inner packing plate 14 through the top opening of the connecting cylinder 33. By controlling the directional flow of the water, the flowing water carries the nitrite and nitrate produced by the metabolism of ammonia-oxidizing bacteria (such as Nitrosomonas) and nitrite-oxidizing bacteria (such as Nitrobacterium) inside the outer packing plate 14 to the inner packing plate 15. Firstly, this flow pattern avoids excessive accumulation of nitrate inside the outer packing plate 14, prevents high concentrations of nitrate from interfering with the uptake of ammonia nitrogen by nitrifying bacteria, and promotes the metabolic efficiency of nitrifying bacteria. Secondly, after the nitrate-containing water flows into the inner packing plate 15, it is utilized by denitrifying bacteria and finally generates harmless nitrogen gas, completing the complete removal of nitrogen and forming a continuous reaction chain of "nitrification-denitrification", further improving the overall denitrification efficiency.

[0038] Techniques to enhance metabolic intensity: In practical applications, such as Figure 2 , Figure 9 and Figure 14 As shown, during the reciprocating motion of the reciprocating screw 21 driving the slider 22 and the scraping folding bar 24, when the scraping folding bar 24 moves downward, the adjusting wheel 25 on one end of the scraping folding bar 24 slides into contact with the vertical section (close to the vertical section of the placement box 12) of the adjusting guide rail 26. During this process, the pressing wheel 27 on the other end of the scraping folding bar 24 moves vertically downward. The pressing wheel 27 does not contact the pushing folding rod 9 on the pushing frame 81. During the upward motion of the scraping folding bar 24... The scraping folding strip 24 drives the adjusting wheel 25 on one end to slide into contact with the vertical section (the vertical section away from the placement box 12) of the adjusting guide rail 26. During this process, the pressing wheel 27 on the other end of the scraping folding strip 24 moves vertically upward. The pressing wheel 27 pushes the bottom inclined section of the pushing rod 9, pushing the pushing rod 9 and the pushing frame 81 to move outward along the axis of the telescopic cylinder towards the outside of the placement box 12. The moving pushing frame 81 drives the square frame 82 on its outer surface to move outward along the axis of the telescopic cylinder towards the outside of the placement box 12. Figure 15 and Figure 16As shown, under the limiting action of the inclined rail 83, the moving frame 82 pushes the lifting wheel 84 and the lifting rod 72 vertically upward through the inclined rail 83. The lifting rod 72 drives the teeth 73 on its outer surface to mesh with the third gear 7, causing the third gear 7 to rotate around its own axis. The third gear 7 drives the rotating block 6 to rotate around the axis of the rotating block 6. As the third gear 7 and the rotating block 6 rotate 90 degrees around the axis of the rotating block 6, the upward-moving teeth 73 separate from the third gear 7, and the lifting rod 72 continues to move upward. The lifting rod 72 drives the limiting strip 74 on its outer surface to move vertically upward, so that the upward-moving limiting strip 74 contacts the outer surface of the limiting block 71, as shown. Figure 17 As shown, since the limiting strip 74 is tightly attached to the outer surface of the limiting block 71, it limits the limiting block 71 and the rotating block 6 (the rotating block 6 cannot rotate around its own axis). As the scraping folding strip 24 and the extrusion wheel 27 continue to move upward, the extrusion wheel 27 presses the vertical section of the pushing rod 9 to fix the position of the pushing rod 9 and the pushing frame 81. As the extrusion wheel 27 continues to move upward, it separates from the pushing rod 9, releasing the extrusion wheel 27's pressing effect on the pushing rod 9. Under the elastic action of the telescopic spring, the telescopic spring pulls the pushing frame 81 along the axis of the telescopic cylinder toward the placement box 12 through the telescopic rod. The pushing frame 81 drives the square frame 82 along the axis of the telescopic cylinder toward the placement box 12. The square frame 82 pushes the lifting wheel 84 and the lifting rod 7 through the inclined rail 83. 2. Moving vertically downwards, the lifting rod 72 drives the limiting bar 74 and the teeth 73 to move downwards, causing the downward-moving limiting bar 74 to separate from the limiting block 71, releasing the limiting effect of the limiting bar 74 on the limiting block 71 and the rotating block 6 (the rotating block 6 can rotate around its own axis). The downward-moving teeth 73 mesh with the third gear 7 again, and the downward-moving teeth 73 drive the third gear 7 to rotate 90 degrees around its own axis. The third gear 7 drives the rotating block 6 to rotate 90 degrees around its own axis again. It can be seen that during the upward movement of the scraping folding bar 24, it first drives the rotating block 6 to rotate 90 degrees around its own axis, and then the rotating block 6 stops rotating. When the upward movement of the scraping folding bar 24 is about to end, the rotating block 6 rotates 90 degrees around its own axis again and remains fixed.

[0039] like Figure 11 , Figure 12 and Figure 13 As shown, during the first rotation of the rotating block 6 around its own axis, the rotating block 6 drives the elliptical guide rail 61 to rotate around the axis of the rotating block 6. Under the guidance of the guide cylinder 5, the rotating elliptical guide rail 61 pushes multiple sealing plates 52 along the axis of the guide cylinder 5 away from the rotating block 6 via the push wheel 62, until the sealing plates 52 on both sides of the outer packing plate 14 and the inner packing plate 15 gradually approach and close. The side of the sealing plate 52 away from the push wheel 62 is made of rubber. Figure 12 and Figure 13As shown, the multiple sets of sealing plates 52, after being closed, form a tortuous "flow channel" between the outer packing plate 14 and the inner packing plate 15. This allows the flowing water to first pass through the top of the outer packing plate 14 along the tortuous "flow channel," then move vertically downwards from the top of the outer packing plate 14 to the bottom of the outer packing plate 14, then enter the bottom of the inner packing plate 15 from the bottom of the outer packing plate 14, then move vertically upwards from the bottom of the inner packing plate 15 to the top of the inner packing plate 15, then enter the center of the placement box 12 from the top of the inner packing plate 15, and then... The water flows sequentially from the center of the placement box 12 along the short pipe 31, the square water pipe 3, and the long pipe 32 into the connecting cylinder 33. The flowing water finally exits from the inside of the connecting cylinder 33 through the top opening of the connecting cylinder 33. In this way, the flowing water can flow evenly along all areas of the outer packing plate 14 and all areas of the inner packing plate 15. On the one hand, this improves the overall nitrate transfer efficiency inside the outer packing plate 14 and avoids excessively high nitrate concentrations in some areas of the outer packing plate 14. On the other hand, it increases the metabolic products of denitrifying bacteria inside the inner packing plate 15, further improving the overall denitrification efficiency and enhancing the treatment effect on wastewater.

[0040] As a further embodiment of the present invention, during the movement of the flowing water through the aforementioned tortuous "channel", the actual flow path length of the water is significantly greater than the straight-line distance. In the tortuous "channel", the contact area between the water and the channel wall increases, and the frictional force increases accordingly. The frictional force consumes the kinetic energy of the water flow, thereby reducing the flow velocity of the water and thus reducing the movement speed of nitrates in the inner packing plate 15. This prolongs the residence time of nutrients such as nitrates in the inner packing plate 15, allowing the microorganisms inside the inner packing plate 15 to fully absorb and take up nutrients in the water, further improving the degradation and transformation efficiency of pollutants in wastewater and ensuring the treatment effect of water pollution.
