Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to an installation process for a MABR module. Background Technology

[0002] Membrane biofilm reactors (MBfR), also known as membrane aerated biofilm reactors (MABR), are essentially a novel biofilm process that can simultaneously perform two functions using membrane materials.

[0003] ① Provide a carrier for biofilms to easily attach and grow;

[0004] ② Deliver gaseous substrates (usually O2) to the biofilm.

[0005] Due to the unique aeration mode and oxygen transfer mechanism of the MABR reactor, the microbial film exhibits a distinct stratified structure, resulting in excellent simultaneous nitrification and denitrification. Its main technical characteristics can be summarized in three points: ① bubble-free aeration, ② heterogeneous mass transfer, and ③ stratified biofilm structure.

[0006] There are currently two types of MABR reactors:

[0007] ① Curtain type, which uses hollow fiber membrane filaments as a carrier for gaseous substrate transport and biofilm attachment;

[0008] ② Plate type: The membrane sleeve made of inner membrane roll is used as a carrier for transporting gaseous substrates and attaching biofilm (plastic supports are set on both sides), and air flows through the inside of the membrane roll.

[0009] Currently, the installation modes of MABR vary depending on the project case, including fixed support installation (including beam-column type, steel frame structure type, etc.) and fixed hoisting installation.

[0010] These installation methods have the following disadvantages:

[0011] 1. The construction time is relatively long, and the tank needs to be emptied before installation, which negates the advantages of MABR technology in rapid installation and installation without interrupting water supply;

[0012] 2. Beams, columns, or steel structures may adversely affect the flow patterns within the biological tank.

[0013] 3. Fixed support installation requires consideration of the maximum wet weight of the membrane module, resulting in higher installation costs;

[0014] 4. Since the beams / columns / steel structure supports are submerged underwater, it is difficult to determine their position during maintenance and reinstallation. Therefore, it is often necessary to add extra hoisting rails or hoisting beams to ensure the accuracy of the installation.

[0015] 5. Hoisting installation requires strength from the cover plate and pool sidewalls; while support installation requires strength from both the pool sidewalls and the pool bottom plate.

[0016] 6. In the single-sided hanging installation mode, in order to ensure the stability of the membrane module installation, a certain amount of space is required at the edge of the pool to facilitate the counterweight support of the fasteners;

[0017] 7. In order to ensure the flow pattern and treatment capacity of the activated sludge process during operation, the length-to-width ratio of the biological tank is subject to certain requirements. If the length and width are not appropriate when the tank is suspended from the side wall, it is easy to cause uneven load on the membrane module or short-circuiting.

[0018] 8. Fixed installation cannot achieve its intended effect.

[0019] In summary, the current installation process for MABR modules has the problem of poor performance. Summary of the Invention

[0020] The main objective of this invention is to provide an installation process for MABR modules to solve the problem of poor performance in the existing installation processes for MABR modules.

[0021] To achieve the above objectives, according to one aspect of the present invention, an installation process for a MABR module is provided. The installation process for the MABR module includes selecting a suspension part, a frame, and a float according to the MABR module; determining the arrangement of the MABR module according to the water area; assembling the frame and float into a pre-assembled unit; sequentially hoisting multiple pre-assembled units to a preset water location and assembling them to form a floating installation body; and immersing the MABR module to a preset depth.

[0022] Furthermore, the steps of selecting the suspension part, frame, and float based on the MABR module include selecting the suspension points of the MABR module; selecting the preset immersion depth and preset tilt / level of the MABR module; selecting the suspension part based on the MABR module; selecting the length of the suspension part based on the distance between the frame suspension point and the suspension point of the MABR module; and selecting the float based on the forces acting on the MABR module, suspension part, and frame.

[0023] Furthermore, the length of the suspension section is equal to the sum of the distance H1 between the frame suspension point and the suspension point of the MABR module, the adjustable length l1, and the safety length l1, so as to adjust the tilt and immersion depth of the MABR module by adjusting the length of the suspension section.

[0024] Furthermore, the sum of the buoyancy of the float and the buoyancy of the MABR module is at least equal to the sum of the weight of the MABR module, the weight of the suspension part, the weight of the frame, the weight of the operator, the weight of the float, and the weight of the accessories.

[0025] Furthermore, in determining the layout of the MABR modules based on the water area, S 水 >n*L*B+S1, S 水 Where is the area of ​​the water body, n is the number of MABR modules, L is the installation length of the MABR module, B is the installation width of the MABR module, and S1 is the clearance area, which is used for installing pipelines and providing maintenance area.

[0026] Furthermore, in the process of assembling the frame and floats into a pre-assembled unit, the frame is installed on top of the floats to cover them, wherein one or more floats are provided.

[0027] Furthermore, the step of sequentially hoisting multiple pre-installed units to a preset water area location and assembling them to form a floating installation includes installing the first pre-installed unit to the preset water area location, installing the second pre-installed unit to the preset water area location and connecting it to the first pre-installed unit, ... installing the Nth pre-installed unit to the preset water area location and connecting it to the (N-1)th preset unit.

[0028] Furthermore, the Nth pre-assembled unit is spliced ​​with the first pre-assembled unit to form a ring-shaped floating installation.

[0029] Furthermore, after the floating installation is completed, the MABR module installation process also includes installing a fixing device, one end of which is connected to the floating installation, and the other end of which is submerged to the bottom of the water or fixed to the shore; installing walkway panels, which are installed on the top surface of the floating installation; and installing guardrails, which are installed on the top surface of the floating installation.

[0030] Furthermore, the step of immersing the MABR module to a preset depth includes connecting the MABR module to one end of the suspension part; hoisting the MABR module and the suspension part to a preset position and moving them into the interior of the water area; and connecting and fixing the suspension point of the floating installation frame to the other end of the suspension part to position the MABR module.

[0031] Furthermore, after the suspension part is connected to the floating installation body, the length of the suspension part is adjusted to adjust the tilt and immersion depth of the MABR module in the water.

[0032] Furthermore, after the step of immersing the MABR module to a preset depth is completed, the MABR module installation process also includes an inspection step.

[0033] Furthermore, prior to the steps of selecting the suspension components, frame, and float based on the MABR module, the MABR module installation process also includes obtaining the MABR module, which can be obtained through procurement or self-manufacturing.

[0034] The installation process of the MABR module using the technical solution of the present invention includes selecting the suspension part, frame and float according to the MABR module, determining the arrangement of the MABR module according to the water area, splicing the frame and float into a pre-assembled unit, hoisting multiple pre-assembled units to a preset water position in sequence and splicing them to form a floating installation body, and immersing the MABR module to a preset depth.

[0035] As can be seen from the above, when installing the MABR module into the preset water area using the installation process of this application, it can be directly installed into the preset position in the water area without interrupting the water supply, and the installation is not limited by the shape of the water area. By splicing together the components at the preset position in the water area to form a floating installation body, the installation position and buoyancy of the MABR module are provided, which increases the stability and accuracy of the MABR module installation. In addition, the structure of this application is simple, and it is convenient to immerse the MABR module into the water area or remove it from the water area. It is flexible in use and easy to operate. Attached Figure Description

[0045] To address the issue of poor performance in the installation process of existing MABR modules, such as... Figures 1 to 3 As shown, this application provides an installation process for a MABR module.

[0046] The installation process for MABR modules includes:

[0047] Based on the MABR module 10, select the suspension part 30, the frame 40 and the float 20;

[0048] The layout of MABR module 10 is determined based on the water area;

[0049] The frame 40 and the float 20 are assembled into a pre-assembled unit;

[0050] Multiple pre-assembled units are sequentially hoisted to the designated water area and then assembled to form a floating installation.

[0051] Immerse the MABR module 10 to the preset depth.

[0052] Specifically, when installing the MABR module 10 into a preset water area using the installation process of this application, it can be directly installed into the preset position in the water area without interrupting the water supply, and the installation is not limited by the shape of the water area. By splicing together a floating installation body at the preset position in the water area, the installation position and buoyancy of the MABR module 10 are provided, which increases the stability and accuracy of the installation of the MABR module 10. In addition, the structure of this application is simple, and it is convenient to immerse the MABR module 10 into the water area or remove it from the water area. It is flexible and easy to use.

[0053] Furthermore, before selecting the suspension component 30, frame 40, and float 20 based on the MABR module 10, the MABR module installation process also includes obtaining the MABR module 10. The MABR module 10 can be obtained through procurement or self-manufacturing. When obtaining the MABR module 10, it is necessary to determine its dry weight, wet weight, and buoyancy. The dry weight, wet weight, and buoyancy of the MABR module 10 can be obtained through self-testing or directly from the nameplate of the MABR module 10.

[0054] It should be noted that the steps of selecting the suspension part 30, frame 40 and float 20 according to the MABR module 10 include selecting the suspension points of the MABR module 10; selecting the preset immersion depth of the MABR module 10; selecting the suspension part 30 according to the MABR module 10; selecting the length of the suspension part 30 according to the distance between the suspension point of the frame 40 and the suspension point of the MABR module 10; and selecting the float 20 according to the forces acting on the MABR module 10, the suspension part 30 and the frame 40.

[0055] In selecting the suspension points for the MABR module 10, closer proximity to the frame 40 is not always better. The suspension points need to be selected based on the stability of the connection between the MABR module 10 and the suspension part 30, i.e., the strength of the MABR module 10 needs to be taken into account. The suspension points for the MABR module 10 are located at the lifting bolt ports, high-strength bolt holes, supporting columns, and supporting beams on the mounting housing of the MABR module 10. The suspension point is a1, and the distance from the suspension point a1 to the top surface of the MABR module 10 is h2.

[0056] In selecting the preset immersion depth and preset tilt / levelness of the MABR module 10, it is necessary to determine the levelness, immersion depth, and water-facing surface of the MABR module 10 based on factors such as the water flow conditions of the water area. The levelness refers to the tilt of the upper plane of the MABR module 10 relative to the water surface, and the water-facing surface refers to the structural surface of the MABR module 10 that interacts with the water flow, ensuring that the MABR module 10 can operate normally within the water area. The immersion depth of the MABR module 10 is h1.

[0057] During the selection of the suspension section 30 according to the MABR module 10, the wet weight m of the MABR membrane assembly is considered. 膜湿 Calculate the membrane module load F 膜负荷 =K1·(m 膜湿 *Gravity acceleration g+Q), where Q is the self-weight of the suspended part (30). K1 is the dynamic load coefficient, generally ranging from 1.1 to 1.3, but can be adjusted appropriately depending on the situation. The tensile strength and breaking strength of commonly used lifting components can be found in the "Common Data Handbook for Lifting and Hoisting," or the required strength of the suspension components can be calculated using conventional material mechanics methods, and the type, form, material, specifications, and mass (m) can be selected. 悬挂 .

[0058] When selecting the suspension component 30, whether it is rigid or flexible, it must meet the strength requirements.

[0059] In selecting the length of the suspension part 30 based on the distance between the suspension point of the frame 40 and the suspension point of the MABR module 10, it is necessary to consider the situation where the MABR module 10 needs to be adjusted in position, such as the tilt angle. Therefore, the length H0 of the suspension part 30 is equal to the sum of the distance H1 between the suspension point of the frame 40 and the suspension point of the MABR module 10, the length l1 of the adjustable part, and the safety length l2, so as to adjust the tilt and immersion depth of the MABR module 10 by adjusting the length of the suspension part 30.

[0060] In obtaining the length of the suspension structure, it is also necessary to consider the safety length l2 required when the suspension part 30 is connected to the suspension point, such as the winding length when it is wrapped around the suspension point.

[0061] In the process of selecting the suspension part 30, the suspension part 30 can be a flexible boom or a rigid boom. The rigid boom is made of galvanized carbon steel or fiberglass-coated carbon steel, while the flexible boom can be a rope or cable structure.

[0062] In selecting the float 20 based on the stress on the MABR module 10, suspension part 30, and frame 40, the float 20 is made of a corrosion-resistant material. For example, the float 20 can be made of fiberglass, aluminum, stainless steel, or other corrosion-resistant materials. The float 20 is not limited to these materials and can also be made of other corrosion-resistant materials. The float 20 is not limited to being made of corrosion-resistant materials; it can also have an anti-corrosion coating on its outer surface to achieve a corrosion-resistant effect. For example, fiberglass coatings, heat-resistant coatings, or other anti-corrosion paints that meet ISO20340-2009 standards can be used inside and outside the float 20 for corrosion protection.

[0063] When considering the buoyancy of float 20, the sum of the buoyancy of float 20 and the buoyancy of MABR module 10 must be at least equal to the sum of the weight of MABR module 10, the weight of suspension part 30, the weight of frame 40, the weight of operator, the weight of float 20 and the weight of accessories. Of course, when selecting float 20, the weight of accessories, such as the weight of railings and walkway 50, must also be considered.

[0064] The float 20 has a draft h4 below the water surface and an adjustment height h3 above the water surface, wherein the draft h4 is equal to the immersion depth h1 of the MABR module 10, and the distance between the float 20 and the suspension point of the frame 40 is b1, and H0 = h1 + h2 + h3 + b1 + l1 + l2.

[0065] Since the float 20 provides buoyancy, multiple floats 20 can be selected simultaneously to provide buoyancy during the selection process.

[0066] Before installing the MABR module 10, the water area needs to be measured to determine the placement and quantity of the MABR module 10. 水 >n*L*B+S1, S 水 Where is the area of ​​the water body, n is the number of MABR modules 10, L is the installation length of the MABR module 10, B is the installation width of the MABR module 10, and S1 is the clearance area, which is used for installing pipelines and providing maintenance area.

[0067] The installation length L of the MABR module 10 is greater than the actual length L1 of the MABR module 10, and the installation width B of the MABR module 10 is greater than the actual width B1 of the MABR module 10. This is because the water flow will change when the MABR module 10 is installed, so the actual installation size is greater than the size of the net space for the MABR module 10 to be installed.

[0068] By setting an obstacle avoidance area S1 for installing pipelines, such as vent pipes and liquid pipes, it is also convenient for operators to enter the water area to inspect and replace the MABR module 10 and pipelines when maintenance is required.

[0069] During the assembly of the frame 40 and the float 20 into a pre-assembled unit, the frame 40 is installed on top of the float 20 to cover the float 20, wherein one or more floats 20 are provided.

[0070] In this process, after selection, the frame 40 and the float 20 are prefabricated into pre-assembled units. During prefabrication, the frame 40 is placed on the top surface of the float 20. The connection between the frame 40 and the float 20 can be a detachable connection method, such as plug-in connection, snap-fit ​​connection, or connection through fasteners, to ensure that the float 20 and the frame 40 are fixed during the installation process. For example, the fasteners can be bolts.

[0071] The step of sequentially hoisting multiple pre-installed units to a preset water area location and assembling them to form a floating installation includes installing the first pre-installed unit to the preset water area location, installing the second pre-installed unit to the preset water area location and connecting it to the first pre-installed unit, ... installing the Nth pre-installed unit to the preset water area location and connecting it to the (N-1)th pre-installed unit.

[0072] After installing the first pre-assembled unit at the designated water area location, the second pre-assembled unit is installed at the same location and connected and secured to the first pre-assembled unit. This process is repeated for the third pre-assembled unit, and finally, the Nth pre-assembled unit is secured. Two adjacent pre-assembled units can be connected and secured using fasteners, such as high-strength bolts. This pre-assembled unit assembly method allows for easy repair if a single pre-assembled unit malfunctions; only that unit needs to be replaced, reducing costs and simplifying operation.

[0073] In this embodiment, the Nth pre-installed unit is spliced ​​with the first pre-installed unit to form a ring-shaped floating mounting body. By forming a ring structure, an installation position is provided for the MABR module 10, that is, the MABR module 10 is installed in the central area of ​​the ring.

[0074] After the floating installation is completed, a rubber sheet or rubber mat can be used as a buffer and anti-collision device on the outermost contact surface of the floating installation to prevent collisions or friction.

[0075] After the floating installation is completed, the MABR module installation process also includes installing a fixing device 70. One end of the fixing device 70 is connected to the floating installation, and the other end of the fixing device 70 is submerged to the bottom of the water or fixed to the shore.

[0076] The fixing device 70 can be either a sunken fixing or a shore-side fixing.

[0077] In the sunken fixing method, the fixing device 70 is composed of a fixing anchor, a steel cable, a spring, and a concrete counterweight. The fixing anchor is sunk to the bottom of the water to achieve the fixing function.

[0078] Furthermore, the connection between the concrete assembly blocks and the fixed anchor bolts has a spring that stores a certain amount of elastic potential energy, so as to have a certain adjustment capability and maintain the fixation of the overall floating device at all times.

[0079] In the shore-side fixing method, the fixing device 70 consists of a combination of fixing bolts, steel cables or fixing ropes, and springs. The fixing bolts are connected to the positioning point on the shore for positioning.

[0080] Furthermore, the connection point between the anchor bolt and the steel cable or fixing rope is equipped with a spring that stores a certain amount of elastic potential energy, so as to have a certain adjustment capability and maintain the fixation of the overall floating device at all times.

[0081] After the floating installation is completed, the installation process of the MABR module also includes installing a walkway plate 50. A movable and detachable walkway plate 50 is installed on the top surface of the floating installation to hide pipelines and other equipment under the walkway plate.

[0082] The choice of walkway slab 50 can be based on the water area; for example, the size of the walkway slab 50 selected for seawater is larger than that for freshwater.

[0083] After the floating installation body is installed, the installation process of the MABR module also includes installing guardrail 60, which is set on the top surface of the floating installation body.

[0084] During the installation of guardrail 60, the guardrail 60 is installed on the outer periphery of the floating installation body to prevent operators or objects on the top surface of the floating installation body from falling into the water.

[0085] Furthermore, the guardrail 60 is equipped according to national standards. If there are many corresponding pipes for the MABR components, reinforced pipe support devices and pipes can be used to serve as a certain guardrail 60 effect, saving investment materials and being green and environmentally friendly.

[0086] The step of immersing the MABR module 10 to a preset depth includes connecting the MABR module 10 to one end of the suspension part 30; hoisting the MABR module 10 and the suspension part 30 to a preset position and moving them into the interior of the water; and connecting and fixing the suspension point of the floating installation frame 40 to the other end of the suspension part 30 to position the MABR module 10.

[0087] As the MABR module 10 enters the preset position and moves into the interior of the water to the preset depth, the suspension part 30 is snapped together with the frame 40 to ensure a stable connection between the suspension part 30 and the frame 40, thereby ensuring that the MABR module 10 remains at the preset depth.

[0088] The tilt, water-facing surface, and preset depth of the MABR module 10 can be adjusted by adjusting the length of the suspension part 30.

[0089] After the step of immersing the MABR module 10 to the preset depth is completed, the MABR module installation process also includes an inspection step. During the inspection, it is necessary to check the tightness of each connecting component, the tilt of the MABR module 10, the water-facing side of the MABR module 10, and the preset depth of the MABR module 10.

[0090] After the inspection steps are completed, the installation process for the MABR module also includes piping installation and instrumentation installation.

[0091] After the piping and instrumentation are installed, a comprehensive inspection is conducted to check whether the MABR module 10 is functioning properly. When the MABR membrane module needs to be lifted out for maintenance, maintenance personnel only need to open the clips at the keel suspension point connection of the frame 40 to lift the membrane module and suspension part 30 out as a whole. The entire installation and construction can be carried out without interrupting the water supply, and the installation method is simple.

[0092] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0093] The installation process of the MABR module using the technical solution of the present invention includes selecting the suspension part 30, frame 40 and float 20 according to the MABR module 10, determining the arrangement of the MABR module 10 according to the water area, splicing the frame 40 and float 20 into a pre-installed unit, hoisting multiple pre-installed units to a preset water position in sequence and splicing them to form a floating installation body, and immersing the MABR module 10 to a preset depth.

[0094] As can be seen from the above, when installing the MABR module 10 into the preset water area using the installation process of this application, it can be directly installed into the preset position in the water area without stopping the water supply, and the installation is not limited by the shape of the water area. By splicing together the components at the preset position in the water area to form a floating installation body, the installation position and buoyancy of the MABR module 10 are provided, which increases the stability and accuracy of the installation of the MABR module 10. In addition, the structure of this application is simple, and it is convenient to immerse the MABR module 10 into the water area or remove it from the water area. It is flexible in use and easy to operate.
