Technical Field
[0001] This invention belongs to the field of wastewater treatment technology, specifically, it relates to an integrated device for membrane oxygen transfer biofilm reactor. Background Technology
[0002] Membrane bioreactors (MBRs) are widely used in wastewater treatment. During operation, wastewater first enters the reaction chamber. In the biological treatment stage, microorganisms attach to a biofilm carrier and decompose and transform pollutants in an aerobic environment. The aeration system introduces air through aeration devices fixed to the bottom or side walls of the chamber, supplying oxygen to the microorganisms and mixing the reaction liquid. Finally, the membrane module separates the solid and liquid components of the mixture, and the purified water is discharged through the membrane, achieving wastewater purification.
[0003] Existing aeration systems typically have aeration pipes fixedly installed at the bottom of the reaction chamber, continuously blowing air into the reaction liquid. While the rising bubbles can mix the reaction liquid, the fixed position of the aeration pipes makes it difficult to achieve uniform aeration distribution. In actual operation, local areas may have excessively high oxygen concentrations while other areas suffer from insufficient oxygen supply, preventing microorganisms from having a suitable aerobic environment and severely impacting pollutant degradation efficiency.
[0004] In view of this, the present invention is proposed. Summary of the Invention

The diameter of the limiting plate is larger than the diameter of the sliding rod, and the limiting plate is used to prevent the sliding plate and the sliding rod from disengaging.
[0011] In a preferred embodiment of the present invention, the drive assembly includes a rocker arm, which is rotatably mounted on the side wall of the aerobic reaction chamber. A synchronous shaft is mounted at the rotation center of the rocker arm, and the synchronous shaft is movably connected to the outer shell of the MBR membrane bioreactor.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.
[0021] Example 1: As Figures 1 to 9 The present invention relates to an integrated membrane oxygen transfer biofilm reactor device, comprising an MBR membrane bioreactor 1 and an aerobic reaction chamber 11 located therein.
[0022] Inside the aerobic reaction chamber 11, there is a pair of aeration pipes 2 that slide vertically and alternately. The aeration pipes 2 slide alternately on the aerobic reaction chamber 11 to mix the reaction liquid and to adjust the aeration position. Each pair of aeration pipes 2 has several pairs of staggered micro aeration holes 22 on its sidewall. A drive assembly is installed on the side wall of the aerobic reaction chamber 11. The drive assembly is used to drive the aeration pipe 2 to slide alternately. A synchronization plate 4 is installed inside the aeration pipe 2. Adjusting rods 41 are installed at both ends of the synchronization plate 4. The adjusting rods 41 correspond to the conical surfaces 411 on the sidewalls of the micro-aeration holes 22. A pair of adjusting slide rails 441 are installed on the sidewalls of the aerobic reaction chamber 11. The adjusting slide rails 441 are inclined, and the synchronization plate 4 slides along the adjusting slide rails 441 to adjust the aeration rate according to the sliding depth. This design allows the aeration pipe 2 to flexibly adjust the aeration position and aeration rate, improving the equipment's adaptability to different wastewater qualities and treatment needs, and enhancing the wastewater treatment effect.
[0023] like Figures 1 to 9 As shown in the specific embodiment, the top of the aerobic reaction chamber 11 is covered with a cover plate 111, and mounting plates 112 are welded around the cover plate 111. The mounting plates 112 are attached to the outer shell of the MBR membrane bioreactor 1 and are connected to the outer shell of the MBR membrane bioreactor 1 by bolts. The bottom of the aerobic reaction chamber 11 is provided with a slope 113, which is used to guide the precipitate to the corner of the aerobic reaction chamber 11. This structure facilitates the installation and disassembly of the aerobic reaction chamber 11, and is conducive to internal cleaning and maintenance. At the same time, the slope 113 can effectively collect the precipitate, prevent it from spreading in the reaction chamber and affecting the treatment effect, and facilitate subsequent centralized cleaning.
[0024] like Figures 1 to 9 Furthermore, a ladder 12 is installed on the side wall of the MBR membrane bioreactor 1, with the top of the ladder 12 flush with the top of the MBR membrane bioreactor 1. A fixing frame 121 is welded to the side wall of the ladder 12. Several opposing poles 13 are installed on the top of the MBR membrane bioreactor 1, and a fence 131 is installed between the opposing poles 13. The ladder 12 and the fence 131 provide a safe and convenient maintenance passage and protective facilities for personnel, ensuring their safety during equipment maintenance and monitoring operations and reducing safety hazards.
[0025] Example 2: The difference between this example and the above examples is as follows: Figures 1 to 9 As shown, a conveying pipe 21 is installed at the bottom of the aeration pipe 2. The conveying pipe 21 is connected to the aeration conveying system. The conveying pipe 21 is a flexible hose. A conveying cavity 211 is opened inside the aeration pipe 2. One end of the conveying cavity 211 communicates with the micro aeration holes 22, and the other end of the conveying cavity 211 communicates with the conveying pipe 21. The synchronization plate 4 is placed in the conveying cavity 211. The flexible hose material of the conveying pipe 21 ensures that the connection of the aeration conveying system is not obstructed during the sliding process of the aeration pipe 2, thus ensuring the continuity and stability of the aeration process.
[0026] like Figures 1 to 9As shown in the specific embodiment, the aeration pipe 2 is a flat rectangular shape, and the aeration pipe 2 provides more thorough stirring of the reaction liquid during movement. Four sliding plates 23 are installed on the side wall of the aeration pipe 2, and a sliding rod 231 is vertically installed through each sliding plate 23. The bottom of the sliding rod 231 is installed at the bottom of the aerobic reaction chamber 11, and a limiting plate 232 is installed at the top of the sliding rod 231. The diameter of the limiting plate 232 is larger than the diameter of the sliding rod 231, and the limiting plate 232 is used to prevent the sliding plate 23 and the sliding rod 231 from disengaging. The flat rectangular shape of the aeration pipe 2 increases the contact area with the reaction liquid, improving the stirring effect. The combination of the sliding plates 23, the sliding rods 231, and the limiting plate 232 ensures the smoothness and reliability of the sliding process of the aeration pipe 2, reducing equipment malfunctions.
[0027] like Figures 1 to 9 Further, the drive assembly includes a rocker arm 3, which is rotatably mounted on the side wall of the aerobic reaction chamber 11. A synchronous shaft 311 is mounted at the rotation center of the rocker arm 3, and the synchronous shaft 311 is movably connected to the outer shell of the MBR membrane bioreactor 1. A swing motor 31 is mounted on the outer shell of the MBR membrane bioreactor 1, and the output end of the swing motor 31 is connected to the synchronous shaft 311. A pair of sliding grooves 32 are provided on the rocker arm 3, located on both sides of the synchronous shaft 311. The pair of sliding grooves 32 correspond to a pair of aeration pipes 2, and a protrusion 321 is mounted on the outer shell of the aeration pipe 2. The protrusion 321 is slidably connected to the sliding groove 32, and the support of the protrusion 321 is adapted to the width of the sliding groove 32. The sliding groove 32 is straight. When the swing motor 31 is started, its output end drives the synchronous shaft 311 to rotate, thereby causing the rocker arm 3 to swing around the rotation center of the synchronous shaft 311. Because the protrusion 321 on the outer shell of the aeration pipe 2 is slidably connected to the groove 32 on the rocker arm 3, the swinging of the rocker arm 3 can drive a pair of aeration pipes 2 to slide vertically and alternately within the aerobic reaction chamber 11. During the sliding process, the micro-aeration holes 22 on the sidewalls of the aeration pipes 2 continuously release air into the reaction liquid. This achieves thorough mixing of the reaction liquid, allowing pollutants in the wastewater to fully contact the microorganisms attached to the biofilm. Furthermore, by adjusting the aeration position through alternating sliding, it ensures that all areas within the aerobic reaction chamber 11 receive sufficient and uniform oxygen, creating a favorable aerobic environment for the microorganisms.
[0028] Example 3: The difference between this example and the above examples is as follows: Figures 1 to 9As shown, a protective frame 422 is installed at the end of the aeration pipe 2. A positioning rod 421 is horizontally installed on the protective frame 422. A pair of positioning plates 42 are slidably mounted on the positioning rod 421. Each positioning plate 42 is connected to the side wall of the corresponding synchronization plate 4. A return spring 423 is sleeved on the positioning rod 421. One end of the return spring 423 is engaged with the side wall of the positioning plate 42, and the other end is connected to the side wall of the protective frame 422. The combination of the protective frame 422, positioning rod 421, positioning plate 42, and return spring 423 provides stable support and a reset function for the synchronization plate 4, enhancing the stability and durability of the aeration volume adjustment structure.
[0029] like Figures 1 to 9 As shown in the specific embodiment, a top rod 43 is installed at the center of each pair of positioning plates 42. The top rod 43 movably passes through the side wall of the protective frame 422, and a slider 431 is installed at the end of the top rod 43. The slider 431 is slidably connected to the surface of the adjusting slide rail 441. The setting of the top rod 43 and the slider 431 makes the sliding of the synchronization plate 4 on the adjusting slide rail 441 smoother and more precise, thereby ensuring the accuracy of aeration volume adjustment.
[0030] like Figures 1 to 9 Furthermore, a back plate 44 is installed on the back of the adjusting slide rail 441. The back plate 44 is welded to the side wall of the aerobic reaction chamber 11. The gap between the tops of a pair of adjusting slide rails 441 is larger than the gap between the bottoms of a pair of adjusting slide rails 441, and the pair of adjusting slide rails 441 are V-shaped. The back plate 44 enhances the installation stability of the adjusting slide rails 441, while the V-shaped design of the adjusting slide rails 441 enables linear adjustment of the aeration volume and the sliding depth of the aeration pipe 2, making the aeration volume adjustment more flexible and precise.
[0031] The implementation principle of the integrated membrane oxygen transfer biofilm reactor of the present invention is as follows: First, wastewater is fed into the aerobic reaction chamber 11 of the MBR membrane bioreactor 1. Microorganisms attach to the biofilm and, in an aerobic environment, use the organic matter in the wastewater as a nutrient source to carry out metabolism, decomposing it into carbon dioxide, water and the microorganisms' own substances, thereby achieving the degradation of pollutants in the wastewater. Then, the wastewater is aerated through the aeration pipe 2.
[0032] During the aeration process, the operator starts the swing motor 31, whose output drives the synchronous shaft 311 to rotate, thereby causing the rocker arm 3 to swing around the rotation center of the synchronous shaft 311. Since the protrusion 321 on the outer shell of the aeration pipe 2 is slidably connected to the groove 32 on the rocker arm 3, the swing of the rocker arm 3 drives a pair of aeration pipes 2 to slide vertically and alternately within the aerobic reaction chamber 11. During the sliding process, the micro-aeration holes 22 on the sidewalls of the aeration pipes 2 continuously release air into the reaction liquid. This achieves thorough mixing of the reaction liquid, allowing pollutants in the wastewater to fully contact the microorganisms attached to the biofilm. Furthermore, by adjusting the aeration position through alternating sliding, it ensures that all areas within the aerobic reaction chamber 11 receive sufficient and uniform oxygen, creating a favorable aerobic environment for the microorganisms. With such a sufficient oxygen supply, microorganisms use the organic matter in the wastewater as nutrients to carry out vigorous metabolic activities, decomposing the organic matter into carbon dioxide, water, and their own substances, thereby effectively degrading pollutants in the wastewater and completing the key step of biological treatment. The membrane module inside the MBR membrane bioreactor 1 plays a crucial role in the solid-liquid separation stage of the post-reaction mixture. The membrane module acts like a "filter," trapping microorganisms and undegraded solid pollutants, allowing only the treated clean water to pass through and be discharged, thus ensuring that the effluent quality meets high standards.
[0033] Regarding aeration volume adjustment, when the aeration pipe 2 slides along the adjusting slide rail 441, the synchronization plate 4 moves accordingly. The adjusting rods 41 at both ends of the synchronization plate 4 cooperate with the conical surfaces 411 on the sidewalls of the micro-aeration holes 22 to form an aeration volume adjustment mechanism. The pair of adjusting slide rails 441 are V-shaped, with the gap between the tops being larger than the gap between the bottoms. This special structural design makes the sliding depth of the aeration pipe 2 closely related to the aeration volume. When the aeration pipe 2 moves upward, due to the tilt angle of the adjusting slide rails 441, the synchronization plate 4 drives the adjusting rods 41 to move upward along the conical surfaces 411. As the position of the adjusting rods 41 on the conical surfaces 411 gradually rises, their squeezing effect on the sidewalls of the micro-aeration holes 22 increases, and the opening of the micro-aeration holes 22 becomes smaller. At this time, the channel for air to flow from the conveying pipe 21 through the conveying inner cavity 211 to the micro-aeration holes 22 narrows, reducing the amount of air discharged per unit time, thereby reducing the aeration volume. Conversely, when the aeration pipe 2 slides to the bottom of the adjusting slide rail 441, the position of the adjusting rod 41 on the conical surface 411 causes the opening of the micro aeration holes 22 to widen, allowing more air to be discharged from the micro aeration holes 22 through the conveying pipe 21 and the conveying inner cavity 211, thus increasing the aeration volume. This design can automatically adjust the aeration volume according to actual needs, avoiding energy waste. Meanwhile, the return spring 423 sleeved on the positioning rod 421 plays a crucial role in the movement of the aeration pipe 2. When the aeration pipe 2 moves upward, the return spring 423 is in a compressed state, providing stable elastic support to the synchronization plate 4, ensuring smooth movement of the adjusting rod 41 on the conical surface 411, avoiding fluctuations in the aeration volume due to equipment vibration or other external interference, and ensuring the stability and accuracy of aeration volume adjustment. The inclined surface 113 at the bottom of the aerobic reaction chamber 11 can guide the precipitates generated during the reaction to the corner of the aerobic reaction chamber 11, facilitating subsequent centralized treatment and discharge of the precipitates and preventing the accumulation of precipitates in the reaction chamber from affecting the normal operation and treatment effect of the equipment. The ladder 12 on the side wall of the MBR membrane bioreactor 1 and the railing 131 on the top provide safe and convenient conditions for personnel to inspect, maintain and monitor the equipment.
