Description

Technical Field

[0001] This utility model relates to the field of water environment treatment technology, and in particular to an EHBR membrane modular three-dimensional layout structure. Background Technology

[0002] In the field of water environment treatment, EHBR technology, as a highly efficient pollutant purification technology, relies on the rational layout and application of the EHBR membrane. The working principle of the EHBR membrane is as follows: when the blower supplies air to the membrane fibers through the aeration pipe, oxygen can permeate from the hollow cavity to the membrane surface, creating an oxygen-rich environment suitable for the attachment and growth of aerobic microorganisms such as heterotrophic bacteria and nitrifying bacteria. As oxygen is gradually consumed during outward diffusion within the biofilm, the outer biofilm becomes dominated by anaerobic microorganisms, forming a biofilm structure completely opposite to that of the microbial carrier in conventional contact oxidation technologies. Pollutants such as ammonia nitrogen and organic matter diffuse from the wastewater side to the inner biofilm, forming a reverse mass transfer between reducing pollutants and oxygen within the biofilm. This improves the substrate utilization efficiency of microorganisms and enables simultaneous nitrification and denitrification, enhancing the removal of ammonia nitrogen and total nitrogen from wastewater, thereby improving pollutant purification capacity.

[0003] The existing EHBR membrane layout uses a traditional flat-lay type, which is a single-layer, full-area arrangement, specifically located in the water layer about 1 meter below the riverbed, such as... Figure 6 As shown, because the membrane is a flexible material, a large number of fixing posts are required, and these posts are generally made of simple plastic pipes. This flat layout has significant drawbacks: firstly, the flat layout uses a smaller number of membranes, thus limiting processing efficiency; secondly, the fixing posts, made of simple plastic pipes, have poor fixing strength and are prone to collapse; and thirdly, the flat layout hinders the removal of silt from the riverbed, making it difficult to perform regular treatment of river silt.

[0004] Therefore, there is an urgent need for a modular three-dimensional layout structure for EHBR membranes to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model discloses a modular three-dimensional layout structure for EHBR membranes. It adopts a modular design combining a rectangular frame and multiple wooden piles. The rectangular frame has a uniform size of 2 meters × 2 meters × 1.5 meters, which facilitates large-scale standardized production and construction, and can effectively shorten the construction cycle. At the same time, the rectangular frame and wooden piles are detachably connected, and the disassembly and installation operations are time-saving and labor-saving, with high efficiency. This allows for the replacement and maintenance of the rectangular frame or wooden piles individually during subsequent use, reducing maintenance costs and difficulties.

[0006] By incorporating a fixed pile mechanism, the structural strength is significantly improved compared to traditional simple plastic pipe fixed piles. Furthermore, the wooden piles are coated with an anti-corrosion paint layer, which, combined with the rust-proof properties of the rectangular frame, enhances the overall structure's corrosion resistance and stability. This effectively prevents collapse and extends the overall service life of the structure.

[0007] By adopting a three-dimensional layout, the membrane body is fixedly hung on a rectangular frame at 20cm intervals. Compared with the traditional flat layout, the installation area of ​​the membrane is increased several times, thereby significantly increasing the contact area between sewage and membrane, and thus effectively improving the pollutant purification efficiency and treatment capacity. In summary, the problems in the background technology are solved.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model discloses an EHBR membrane modular three-dimensional layout structure, including a rectangular frame. The rectangular frame consists of two side frames and four frame tubes. The two side frames are rectangular and hollow inside. The two ends of the four frame tubes are fixedly connected to the two side frames respectively, and the four frame tubes are close to the four inner corners of the side frames respectively. Multiple membrane bodies are fixedly hung on the outside of the four frame tubes.

[0010] The fixed pile mechanism includes four locking seats. The four locking seats are fixedly installed in pairs on the bottom of two side frames, with the two locking seats in the same pair located near the front and rear sides of the side frames. Each locking seat has a rectangular locking groove inside, into which a wooden stake is fitted. The wooden stake has two rectangular limiting grooves inside. The locking seat has two through slots matching the dimensions of the limiting grooves. A mounting frame is fixedly connected to one side of the locking seat. A pull rod is movably mounted through the mounting frame. One end of the pull rod is fixedly connected to an abutment plate. Two limiting blocks are fixedly connected to one side of the abutment plate. The limiting blocks pass through the through slots and engage with the limiting grooves. The side of the abutment plate away from the limiting blocks is elastically connected to the inner side of the mounting frame via multiple springs.

[0011] Furthermore, the side frame and the frame tube are fixedly connected by welding, and both the side frame and the frame tube are made of stainless steel.

[0012] Furthermore, the frame tube is a circular tube, and the distance between adjacent membrane bodies is 20cm.

[0013] Furthermore, multiple sets of limiting rings are fixedly welded to the outside of the frame tube, with two limiting rings in the same set located on opposite sides of the same membrane body.

[0014] Furthermore, the mounting base, mounting bracket, pull rod, and spring are all made of stainless steel. The mounting base is welded to the side frame, and the mounting bracket is welded to the mounting base.

[0015] Furthermore, the bottom of the wooden pile is designed in a pyramid shape, and the outer surface of the wooden pile is coated with an anti-corrosion coating layer, which is an epoxy resin coating.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. This technical solution adopts a modular design combining a rectangular frame and multiple wooden piles. The rectangular frame has a uniform size of 2 meters × 2 meters × 1.5 meters, which facilitates large-scale standardized production and construction, and can effectively shorten the construction cycle. At the same time, the rectangular frame and wooden piles are detachably connected, and the disassembly and installation operations are time-saving and labor-saving, with high efficiency. This allows for the replacement and maintenance of the rectangular frame or wooden piles individually during subsequent use, reducing maintenance costs and difficulty.

[0018] 2. This technical solution, by setting up a fixed pile mechanism, significantly improves the structural strength compared to traditional simple plastic pipe fixed piles. In addition, the wooden pile surface is coated with an anti-corrosion coating layer, which, combined with the rust-proof performance of the rectangular frame, enhances the overall structure's corrosion resistance and stability, thereby effectively preventing collapse and extending the overall service life of the structure.

[0019] 3. This technical solution adopts a three-dimensional layout, with the membrane body fixedly hung on a rectangular frame at 20cm intervals. Compared with the traditional flat layout, the installation area of ​​the membrane is increased several times, thereby greatly increasing the contact area between sewage and membrane, and thus effectively improving the pollutant purification efficiency and treatment capacity.

[0030] Reference Figures 1-5 An EHBR membrane modular three-dimensional layout structure includes a rectangular frame 1, which consists of two side frames 101 and four frame tubes 102. The two side frames 101 are rectangular and hollow inside. The two ends of the four frame tubes 102 are fixedly connected to the two side frames 101 respectively, and the four frame tubes 102 are close to the four inner corners of the side frames 101 respectively. Multiple membrane bodies 2 are fixedly hung on the outside of the four frame tubes 102.

[0031] The fixed pile mechanism includes four clamping seats 3. The four clamping seats 3 are fixedly installed in pairs on the bottom of two side frames 101. The two clamping seats 3 in the same group are close to the front and rear sides of the side frames 101 respectively. The clamping seat 3 has a rectangular clamping groove 4 inside. The clamping groove 4 is matched and clamped with a wooden stake 5. The wooden stake 5 has two rectangular limiting grooves 6 inside. The clamping seat 3 has two through grooves 7 that match the position and size of the limiting grooves 6. The clamping seat 3 is fixedly connected to a mounting frame 8 on one side. The mounting frame 8 is provided with a pull rod 9 in a through-type movement. One end of the pull rod 9 is fixedly connected to an abutment plate 10. Two limiting blocks 11 are fixedly connected to one side of the abutment plate 10. The limiting blocks 11 pass through the through grooves 7 and match and engage with the limiting grooves 6. The side of the abutment plate 10 away from the limiting blocks 11 is elastically connected to the inner side of the mounting frame 8 by multiple springs 12.

[0032] The side frame 101 and the frame tube 102 are fixedly connected by welding, and both the side frame 101 and the frame tube 102 are made of stainless steel. The frame tube 102 is a circular tube, and the distance between adjacent membrane bodies 2 is 20cm. Multiple sets of limiting rings 13 are fixedly welded to the outside of the frame tube 102, and two limiting rings 13 in the same set are located on both sides of the same membrane body 2. The mounting seat 3, the mounting bracket 8, the pull rod 9 and the spring 12 are all made of stainless steel. The mounting seat 3 is welded to the side frame 101, and the mounting bracket 8 is welded to the mounting seat 3. The bottom of the wooden stake 5 is designed in a pyramid shape. The wooden stake 5 is made of pine wood, and the outer surface of the wooden stake 5 is coated with an anti-corrosion coating layer, which is an epoxy resin coating.

[0033] In the specific implementation process, firstly, the two side frames 101 and the four frame tubes 102 are fixedly connected into a whole by welding. Then, multiple membrane bodies 2 are fixedly hung on the four frame tubes 102 at intervals of 20cm, and the limiting rings 13 welded on the frame tubes 102 are used for auxiliary limiting. Next, four fixing pile mechanisms with locking seats 3 are installed at the four corners of the bottom of the rectangular frame 1. By pulling the pull rod 9 outward, the spring 12 is compressed, and the limiting block 11 is retracted into the through groove 7. Then, the bottom of the wooden pile 5 coated with anti-corrosion coating is aligned with the riverbed and driven in. Then, the top of the wooden pile 5 is inserted into the locking groove 4 of the locking seat 3. Finally, the pull rod 9 is released. Under the elastic force of the spring 12, the limiting block 11 passes through the through groove 7 and is locked into the limiting groove 6 of the wooden pile 5, completing the quick locking of the rectangular frame 1 and the wooden pile 5. According to this method, multiple modular EHBR membrane units are arranged longitudinally in a staggered and distributed manner in the river channel to form a three-dimensional layout structure.

[0034] Among them, rectangular frame 1 has a standard size of 2 meters × 2 meters × 1.5 meters;

[0035] The membrane body 2 can be fixed by hooking and connecting it to the frame tube 102. For example, multiple hooks (not shown in the figure) can be fixedly connected to both sides of the membrane body 2. After wrapping the membrane body 2 around the rectangular frame 1, the membrane body 2 can be fixed by hooking it to the frame tube 102. Since there are many ways to fix and hang it, there are many options, so no restrictions or further details are provided here.

[0036] The two ends of the spring 12 are fixedly connected to the abutment plate 10 and the mounting bracket 8 by welding, respectively.

[0037] The fixed connection by welding ensures the overall structural strength and stability of the rectangular frame 1, preventing loosening or disintegration under the impact of water flow; the use of stainless steel gives the frame excellent rust and corrosion resistance, significantly extending its service life in the underwater environment and effectively solving the problem of easy collapse of traditional fixed piles.

[0038] The frame tube 102 is designed as a circular tube, and its smooth surface facilitates the hanging and fixing of the membrane body 2, while avoiding damage to the membrane fibers from sharp edges. The spacing between adjacent membrane bodies 2 is set to 20cm, which not only ensures sufficient membrane area per unit space to improve treatment efficiency, but also provides a smooth channel for water flow, avoiding the impact of excessive crowding between membrane fibers on the contact efficiency between pollutants and biofilm, and ensuring the stability of the purification effect.

[0039] Among them, by welding the limiting ring 13 to the outside of the frame tube 102, the membrane body 2 can be effectively prevented from sliding and translating under the action of water flow, ensuring the regularity of the three-dimensional layout and the constant membrane spacing, thereby ensuring the long-term stable operation of the entire membrane system.

[0040] Among them, key components such as the mounting base 3, mounting frame 8, tie rod 9, and spring 12 in the fixed pile mechanism are all made of stainless steel, ensuring that they have the same corrosion resistance as the main frame. In particular, for moving parts such as tie rod 9 and spring 12, it can prevent jamming due to rust, ensuring the smoothness and reliability of disassembly and assembly operations. At the same time, the mounting base 3 and the side frame 101, and the mounting frame 8 and the mounting base 3 are connected by welding, forming a stable force transmission structure that can reliably transmit the weight of the rectangular frame 1 and the impact force of water flow to the wooden pile 5.

[0041] Among them, the bottom of the wooden pile 5 is designed in a pyramid shape, which makes it easy to drive it into the riverbed during construction, providing a strong initial anchoring force and ensuring the stability of the entire layout structure; the surface of the wooden pile 5 is coated with an epoxy resin anti-corrosion coating layer, forming a dense protective film that effectively isolates the wood from the erosion of moisture and microorganisms, greatly enhancing the corrosion resistance and service life of the wooden pile 5, thus replacing the traditional easily damaged plastic pipes and fundamentally improving the strength and reliability of the fixed piles;

[0042] Multiple modular EHBR membrane units are longitudinally staggered along the water flow direction in the river channel. The horizontal spacing between two adjacent modules is 1.5 meters, the vertical height difference between upper and lower modules is 0.8 meters, and the bottom of all modules is at least 0.5 meters above the riverbed. This ensures that silt removal equipment (such as dredging boats and suction pipes) can move smoothly between modules without any blind spots.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
