Description

Technical Field

[0001] This invention relates to the field of microbial reactor technology, and more specifically to a honeycomb microbial reactor. Background Technology

[0002] The three-dimensional biological grid, also known as the "high-efficiency honeycomb fixed-bed bioreactor," is a leading international biofilm-based wastewater biochemical treatment technology. It follows the growth, co-occurrence, and synergistic effects of microbial communities during wastewater biological treatment. It rationally divides the traditional "mixed" microbial treatment model into several continuous stages as needed, fixing high-concentration, self-regulating, and synergistic microbial communities on a specially designed inert carrier, and performing unit-based and specialized biological treatment of wastewater under direct current conditions.

[0003] The literature (application number: CN200580042748.7) discloses a bioreactor system for multi-stage biological wastewater treatment. This system is consistent with the biofilm state in existing three-dimensional biological racks. However, in actual treatment, the flow patterns in the same reaction tank are not the same. The geometry, channel design, and obstacles in different areas of the reaction tank lead to differences in flow patterns, and the flow velocity also varies at different locations. Especially in large-scale reactors, the flow of fluid near the inlet and outlet and in the central area are different. Under different flow velocity conditions, the surface liquid distribution of biofilm with the same curvature is different, which affects the growth of biofilm and thus the wastewater treatment effect. At the same time, because the biological rack is large in volume, it cannot be tilted or rotated in the tank. Therefore, it is necessary to hoist the reactor and then assemble and weld the aeration pipes on top of the bioreactor. When welding the MCBR aeration pipes, the welding sparks can easily fall onto the biofilm in the reactor. The biofilm is made of silk fabric, which is flammable. The biological shelves are arranged closely in the sulfur autotrophic tank, making them extremely prone to fire. Once ignited, the fire will spread rapidly and cause incalculable losses to construction workers and property. Summary of the Invention

[0004] The purpose of this invention is to provide a honeycomb microbial reactor in order to solve the above problems.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A honeycomb-type microbial reactor includes a frame. Multiple biofilm components are installed inside the frame. Each biofilm component includes an upper frame plate and a lower frame plate welded inside the frame. The upper frame plate is located above the lower frame plate. Multiple upper passageways are formed inside the upper frame plate, and upper swing plates are rotatably installed inside each upper passageway. The multiple upper swing plates can swing synchronously. Multiple lower passageways are formed inside the lower frame plate, and multiple lower swing plates are rotatably installed inside each lower passageway. The swing directions of the lower swing plates are opposite to those of the upper swing plates. A bag-shaped membrane assembly is fixedly connected between the upper and lower swing plates, and the bag-shaped membrane assembly has elastic internal support strips inside. The top of the frame is welded with multiple sets of upper pedals, the number of which is the same as the number of biofilm components.

[0006] Furthermore, a nameplate with a QR code is installed on the top periphery of the frame column, and the equipment number and the number of vent holes are also sprayed on the periphery.

[0007] Furthermore, the frame is constructed using channel steel and angle iron as its skeleton.

[0008] Furthermore, the skeletons are all prefabricated components and are connected to each other by bolts.

[0009] Furthermore, a rotating shaft is rotatably mounted on the outer side of both the upper and lower frame plates, and multiple sets of worm gears are provided on the outer side of the rotating shaft. A worm wheel is fixedly mounted on the outer side of both the upper and lower frame plates, and the worm wheel meshes with the worm gear.

[0010] Furthermore, a torsion spring is provided at the rotation center of the rotating shaft, a driven reel is fixedly installed on the outer side of the rotating shaft, a transmission rope is wound on the outer side of the driven reel, and the transmission ropes on the two driven reels in the same group of biofilm components are wound in opposite directions. A winding motor is fixedly installed on the top of the upper pedal, and an active reel is fixedly installed at the output end of the winding motor. The two transmission ropes in the same group of biofilm components are simultaneously wound on one active reel.

[0011] Furthermore, both the upper and lower frame plates are provided with outer protective shells, and the worm gear, worm, rotating shaft and driven reel are all located in the outer protective shells.

[0012] Furthermore, the top of the upper shelf is provided with a ceramic coating.

[0013] The beneficial effects of this invention are as follows: This invention utilizes the synchronous counter-oscillation of the lower and upper swing plates, along with the elastic internal support strips within the bag-shaped membrane assembly, to control the bending state of the bag-shaped membrane assembly. Furthermore, the arrangement of multiple biofilm components allows for the differentiation of the bending degree of the bag-shaped membrane assembly at different locations, enabling it to adapt to environments with varying flow rates. This results in a wide range of applications and excellent treatment effects.

[0014] This invention controls the upper swing plate to swing upward and seal the upper passage, thereby automatically isolating the bag-shaped membrane assembly. This prevents welding slag from igniting the bag-shaped membrane assembly, ensuring high installation safety and eliminating the need for additional flame-retardant materials, making installation convenient.

[0015] This invention uses the repeated swinging of the lower and upper swing plates to repeatedly change the shape of the bag-shaped membrane assembly, thereby greatly improving the subsequent cleaning efficiency of the bag-shaped membrane assembly. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1, as Figures 1-6As shown, a honeycomb microbial reactor includes a frame 1. Multiple biofilm components 2 are installed inside the frame 1. Each biofilm component 2 includes an upper frame plate 21 and a lower frame plate 24 welded inside the frame 1. The upper frame plate 21 is located above the lower frame plate 24. Multiple upper passages 22 are opened inside the upper frame plate 21. Upper swing plates 23 are rotatably installed inside the upper passages 22. The multiple upper swing plates 23 can swing synchronously. Multiple lower passages 25 are opened inside the lower frame plate 24. Multiple lower swing plates 26 are rotatably installed inside the lower passages 25. The multiple lower swing plates 26 can swing synchronously. The swing direction of the lower swing plates 26 is opposite to that of the upper swing plates 23. A bag-shaped membrane assembly 27 is fixedly connected between the upper swing plates 23 and the lower swing plates 26. An elastic inner support strip 271 is provided inside the bag-shaped membrane assembly 27. The elastic inner support strip 271 is made of plastic. Multiple upper pedals 3 are welded to the top of frame 1, and the number of upper pedals 3 is the same as the number of biofilm components 2.

[0020] During installation, the frame 1 can be vertically suspended from the top or horizontally suspended from the middle, allowing the device to be installed in the reaction tank. Current installation methods are shown in the attached diagram. Figure 6 As shown, a fireproof blanket is first laid as the first layer of protection, and then a fireproof board is laid. Since the reactor is large in volume and quantity, manual laying would waste a lot of time. Therefore, after the device is hoisted, the present invention controls the upper swing plate 23 to swing upward to block the upper passage 22. At this time, the upper frame plate 21 plays a protective role, and there is no need to lay additional fireproof materials, which can greatly save installation time. After installation, based on the flow velocity difference between each layer in the reaction tank, the lower swing plate 26 and the upper swing plate 23 on the corresponding biofilm module 2 are controlled to swing synchronously in opposite directions. The distance between the lower swing plate 26 and the upper swing plate 23 changes, and the bending arc of the bag-shaped membrane module 27 changes under the action of its internal elastic inner support strip 271. This can optimize the liquid flow distribution on the membrane surface, control the membrane arc, and thus affect the growth of the biofilm, which can greatly improve the sewage treatment effect. When the biofilm needs to be cleaned in the future, the lower swing plate 26 and the upper swing plate 23 can be controlled to swing up and down repeatedly, so that the bag-shaped membrane module 27 can be changed repeatedly, which can greatly improve the cleaning efficiency. This invention, through the setting of biofilm component 2, not only ensures welding safety but also allows for adjustment of the shape of bag-shaped membrane module 27, enabling it to adapt to wastewater treatment at different flow rates. It has a wide range of applications and can improve biofilm cleaning efficiency. The structure is simple. In addition, existing reactors do not have an operating position on the top, so it is necessary to prepare a footboard to cover each biological shelf. After laying it, the position needs to be fine-tuned and leveled. The footboard needs to be hoisted, which is cumbersome. This invention, through the setting of upper footboard 3, allows for leveling operations to be performed directly on the reactor.

[0021] The honeycomb microbial reactor of this invention increases the concentration of microorganisms by immobilizing them on an inert fiber carrier. The bacterial concentration is 3-5 times higher than that of traditional A / O and activated sludge processes, reaching up to 12 times higher, and the wastewater treatment efficiency is increased by more than 2 times. Based on water quality and treatment requirements, membrane materials are selected and designed to achieve unitized and specialized biological treatment of wastewater by high-concentration microorganisms. The activated sludge in the reactor is not recirculated back to the initial stage. The spatial succession of microbial colonies allows for more comprehensive and thorough removal of organic matter from wastewater. Complex nutrient and redox chains form on the biofilm, enabling simultaneous nitrification, denitrification, and organic matter degradation. The biofilm is immobilized by the inert carrier. The biofilm detachment is minimal, eliminating the need for additional residual activated sludge sedimentation (no secondary sedimentation tank) and recycling systems; the final residual activated sludge production is reduced by 100-300 times compared to activated sludge process technologies; wastewater retention time is short, treatment efficiency is high, and equipment size is small; the spatial distribution of microbial colonies is modular and specialized, exhibiting strong adaptability to environmental factors such as water volume and temperature; the equipment has strong shock resistance, simple management, and a long service life, requiring no major repairs within 10 years; in the event of process unit shutdown or pollution, restart is rapid and recovery time is short; the effluent quality is excellent, with major indicators such as COD, BOD, ammonia nitrogen, total nitrogen, surfactants, and petroleum hydrocarbons meeting the Class IV environmental surface water standards, except for phosphorus.

[0022] Example 2, based on the above examples, further includes a nameplate QR code installed on the outer perimeter of the top of the frame 1 column, and the outer perimeter is also sprayed with the equipment number and the number of vent holes, so as to facilitate the determination of the installation position during installation.

[0023] Example 3, based on the above examples, further includes a frame 1 made of channel steel and angle iron as a skeleton.

[0024] Furthermore, the frames are all prefabricated and connected to each other by bolts.

[0025] The configuration of this embodiment facilitates device assembly. At the same time, by using channel steel and angle iron as the frame, the strength can be guaranteed while the weight of frame 1 can be greatly reduced, making hoisting convenient.

[0026] Example 4, based on the above examples, further includes a rotating shaft 28 rotatably mounted on the outer side of both the upper frame plate 21 and the lower frame plate 24, with multiple sets of worm gears 29 arranged on the outer side of the rotating shaft 28, and a worm wheel 212 fixedly mounted on the outer side of both the upper swing plate 23 and the lower swing plate 26, with the worm wheel 212 meshing with the worm gear 29.

[0027] In this embodiment, the rotating shaft 28 can be driven by a motor. The rotating shaft 28 drives multiple sets of worm gears 29 to rotate simultaneously. The multiple sets of worm gears 29 drive the upper swing plate 23 of the upper frame plate 21 to swing synchronously through the worm wheel 212. Through the unidirectional transmission characteristic of the worm wheel and worm gear, the angle of the upper swing plate 23 can be kept stable, resulting in high adjustment stability and a compact structure.

[0028] Example 5, based on the above examples, further includes a torsion spring 210 at the rotation center of the rotating shaft 28, a driven winding wheel 211 fixedly installed on the outer side of the rotating shaft 28, a transmission rope wound on the outer side of the driven winding wheel 211, and the transmission ropes on the two driven winding wheels 211 in the same group of biofilm components 2 are wound in opposite directions. A winding motor 4 is fixedly installed on the top of the upper pedal 3, and an active winding wheel 5 is fixedly installed at the output end of the winding motor 4. The two transmission ropes in the same group of biofilm components 2 are simultaneously wound on one active winding wheel 5.

[0029] Since the upper swing plate 23 needs to swing in opposite directions synchronously with the lower swing plate 26, the setup in Embodiment 4 requires simultaneous control of two sets of motors, which is difficult to control. Furthermore, the motors are located in the water and require extremely high sealing. Therefore, this embodiment uses a winding motor 4, which is mounted on the upper pedal 3 and will not enter the water. The winding motor 4 drives the active winding wheel 5 to rotate. The active winding wheel 5 simultaneously winds up the two sets of transmission ropes in the same set of biofilm components 2. Since the transmission ropes on the two sets of driven winding wheels 211 in the same set of biofilm components 2 are wound in opposite directions, the driven winding wheels 211 can simultaneously drive the two sets of rotating shafts 28 to rotate in opposite directions synchronously. The rotating shafts 28, through the worm gear 29 and worm wheel 212, cause the upper swing plate 23 and the lower swing plate 26 to swing in opposite directions synchronously, which simplifies control.

[0030] Example 6, based on the above examples, further includes an outer protective shell 6 provided on the outer sides of both the upper frame plate 21 and the lower frame plate 24. The worm gear 212, worm 29, rotating shaft 28 and driven reel 211 are all located in the outer protective shell 6. Through this embodiment, the service life of the worm gear 212, worm 29, rotating shaft 28 and driven reel 211 can be improved.

[0031] Example 7, based on the above examples, further includes a ceramic coating on the top of the upper rack 21. The ceramic coating prevents welding slag from sticking to the top of the upper rack 21, making cleaning convenient.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
