Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an integrated multifunctional MBR membrane module cleaning equipment. Background Technology

[0002] Biochemical treatment is the most widely used and relatively economical mainstream treatment method in the treatment of large-scale domestic sewage and industrial wastewater. However, in actual operation, it has disadvantages such as large fluctuations in effluent quality and high effluent turbidity. Membrane bioreactor (MBR) combines membrane separation technology with the traditional activated sludge process to achieve more efficient solid-liquid separation, significantly improving treatment effect and system stability.

[0003] During wastewater treatment using MBR, pollutants such as activated sludge flocs, organic / inorganic colloids, and microorganisms gradually form a filter cake layer on the membrane fiber surface through physical adsorption, chemical bonding, and biological adhesion. Some small molecule pollutants also permeate the membrane pores, causing blockage. The combined effect of these two factors leads to a decrease in membrane module flux, requiring frequent cleaning. Currently, commonly used cleaning methods include offline hoisting, disassembly of each module, manual rinsing, and chemical soaking. Each MBR membrane module requires a significant amount of manual labor, and manual cleaning can easily damage the surface of the MBR membrane fibers, resulting in additional losses. Some researchers have also studied mechanical cleaning devices for MBR membrane modules. For example, CN211384553U invented an MBR membrane module cleaning device based on a movable ultrasonic plate, which can accurately position and transport the ultrasonic plate without lifting the membrane module, greatly reducing cleaning costs. CN215627053U invented an MBR membrane module cleaning device that improves cleaning efficiency, facilitates the removal of sludge adhering to the surface of the MBR membrane module, and can promptly notify relevant personnel when the aeration pipe becomes blocked, so that appropriate measures can be taken immediately. However, current mechanical cleaning devices are not effective for cleaning densely packed and severely caked membrane modules, and simple water flushing or chemical soaking methods are also difficult to achieve ideal results. Therefore, developing multifunctional, intelligent, low-cost, high-quality, and environmentally friendly cleaning equipment for MBR membrane modules has become an urgent problem to be solved in the MBR membrane industry. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated, multifunctional MBR membrane module cleaning equipment, which solves the problems of complex cleaning procedures, high labor costs, high chemical costs, unstable cleaning quality, and harsh cleaning environment in existing MBR membrane module cleaning. It achieves intelligent, low-cost, high-efficiency, high-quality cleaning of MBR membrane modules without secondary pollution.

[0005] The technical solution of this invention is as follows: An integrated multi-functional MBR membrane module cleaning equipment, comprising: a cleaning water tank unit, a robot moving unit, a pre-rinsing unit for irregularly shaped multi-pipes, an ultrasonic fine cleaning unit, a chemical dosing backwashing unit, a clean water rinsing unit, a micron-level aeration unit, a sludge discharge unit, and a cleaning water recovery unit, wherein... The cleaning water tank unit includes a cleaning water tank body, an ultrasonic plate slide rail fixing bracket connector, a dosing pipe bracket connector, a cleaning pipe bracket connector, a micron aeration pipe bracket connector, a drain pipe, and a sludge discharge pipe. The preferred dimensions are 3000mm*2500mm*3000mm, which is compatible with commonly used MBR membrane modules in China. The preferred material is 316L stainless steel with a wall thickness of not less than 2.5mm. The drain pipe is installed 20cm-25cm from the bottom of the cleaning water tank and is connected to the cleaning water recovery pump through a drain pipe flange quick connector. The sludge discharge pipe is installed 10cm-20cm from the bottom of the cleaning water tank and is connected to the sludge discharge pump through a sludge discharge pipe flange quick connector. The robot moving unit includes a robot base, a robot, and a robotic arm. One end of the robotic arm is connected to the robot, and the other end is connected to the irregularly shaped multi-tube pre-rinsing unit. Through positioning, the irregularly shaped multi-tube pre-rinsing unit is moved between the MBR membranes and inserted into the membranes from top to bottom to a depth of 1500mm-1800mm. The pre-rinsing unit for the irregularly shaped multi-pipe includes a main inlet pipe, a connecting connector, a robot connector, horizontal pipes, vertical pipes, and openings. The flushing water hose is connected to the main inlet pipe via the connecting connector. The flushing water passes through the horizontal and vertical pipes and the openings (1mm-2mm in diameter) to spray and rinse the sludge that has hardened between the MBR membranes. Simultaneously, the robot moving unit, connected to the flushing unit via the robot connector, moves from top to bottom and sprays the MBR membranes. The ultrasonic cleaning unit includes an ultrasonic plate, an ultrasonic plate slide rail, an ultrasonic generator, and an ultrasonic plate slide rail fixing bracket. During installation, firstly, the ultrasonic plate slide rail fixing bracket is installed inside the cleaning water tank using bolts. Secondly, the ultrasonic plate slide rail is installed, with the preferred distance between the upper and lower ultrasonic plate slide rails being 1500mm-2500mm. Then, the ultrasonic plate is installed. Finally, the ultrasonic generator is connected. During use, when the liquid level in the cleaning water tank exceeds the upper surface of the MBR membrane module, the ultrasonic generator is turned on. The preferred ultrasonic frequency is 20-40Hz. The ultrasonic plate moves with the ultrasonic plate slide rail, with the moving speed controlled at 10cm / min-20cm / min. The chemical dosing backwashing unit mainly includes a dosing pipe with a flange for the permeate pipe, a dosing pipe support, a dosing pump, and a dosing tank. When in use, a certain concentration of reagent is prepared, added to the dosing tank, and pumped into the permeate pipe by the dosing pump, and then permeates from the inside of the MBR membrane fibers to the surface of the membrane fibers. The clean water rinsing unit mainly includes a cleaning pipe connector, a cleaning pipe, a cleaning pipe nozzle, and a cleaning pipe bracket. During installation, the cleaning pipe bracket is installed on the side wall of the cleaning water tank, and then the cleaning pipe and cleaning pipe nozzle are installed. Clean water enters the cleaning pipe through the cleaning pipe connector and flows out from the cleaning pipe nozzle, spraying onto the MBR membrane for rinsing. The micron aeration unit includes a main aeration pipe, branch aeration pipes, a micron aeration pipe support, and a micron aeration disc. The micron aeration disc has several small holes with a diameter of 10mm-100mm. The compressed air pressure is 1-3 bar and it is connected to the main aeration pipe. Through the micron aeration disc, emulsified bubbles are formed in the cleaning tank. The sludge discharge unit includes sludge flushing nozzles, a sludge collection trough at the bottom of the cleaning water tank, a sludge discharge pump, a sludge discharge pipe, and a sludge discharge valve. The diameter of the sludge discharge pipe is preferably DN200mm-DN250mm. The sludge flushing nozzles at the bottom of the cleaning water tank are arranged around the cleaning water tank. The pressure of the sludge flushing nozzles is 0.3MPa-0.6MPa. The sludge collection trough at the bottom of the cleaning water tank has a wedge-shaped design. The flushing nozzles at the bottom of the cleaning water tank can flush the sludge-containing wastewater to the sludge collection trough at the bottom of the cleaning water tank, and then discharge it to the outside of the cleaning water tank through the sludge discharge pump. The cleaning water recovery unit includes a drain pipe, a drain pipe valve, a cleaning water recovery pump, and a cleaning water recovery tank. The drain pipe is installed 20cm-25cm away from the bottom of the cleaning water tank, and the drain pipe diameter is preferably DN100cm-DN150cm.

[0006] When the integrated multi-functional MBR membrane module cleaning equipment of the present invention is in operation, the MBR membrane module is disassembled from the membrane tank and hoisted into the integrated multi-functional MBR membrane module cleaning equipment as a whole. The robot moving unit, the irregular multi-pipe pre-rinsing unit, the sludge discharge unit at the bottom of the cleaning water tank, the chemical dosing backwashing unit, the clean water rinsing unit, the ultrasonic fine cleaning unit, the micron aeration unit, and the cleaning water recovery unit are activated in sequence, as follows: First, the robot moving unit and the irregular multi-pipe pre-rinsing unit are activated. The robot drives the irregular multi-pipe pre-rinsing unit to move and rinse between the MBR membranes from top to bottom. The sludge that has hardened between the MBR membranes falls to the bottom of the cleaning water tank with the rinsing water. After rinsing, it enters the next set of MBR membranes for cleaning. Second, the sludge discharge unit at the bottom of the cleaning water tank is activated. In the first unit, the flushing water from the sludge flushing nozzles washes away the concentrated sludge solution, which flows through the sludge collection trough at the bottom of the cleaning water tank and into the sludge discharge pipe, where it is discharged by the sludge discharge pump. Then, the chemical dosing backwashing unit and the clean water flushing unit are activated, flushing the surface of the MBR membrane fibers with clean water while simultaneously introducing chemicals into the interior of the MBR membrane fibers. Once the overall liquid level exceeds the top of the MBR membrane, the clean water flushing unit is stopped. Next, the ultrasonic fine cleaning unit and the micron-level aeration unit are activated, allowing the cleaning agents to fully react with the contaminants on and inside the MBR membrane fibers, deeply removing contaminants. After a period of reaction, the ultrasonic fine cleaning unit and the micron-level aeration unit are stopped. Finally, the cleaning water recovery unit is activated, pumping the cleaning water from the MBR membrane tank back to the cleaning water tank. This cleaning water is then used for the clean water flushing unit of the next set of MBR membrane modules.

[0007] Compared with existing technologies, this invention has significant advantages: First, within the integrated multifunctional MBR membrane module cleaning equipment, the MBR membrane module is cleaned as a whole, without the need to disassemble it into individual membrane sheets for cleaning, greatly reducing the manual labor intensity of membrane cleaning, and the operating environment is closed, ensuring a clean cleaning site; Second, the MBR membrane module undergoes graded, coordinated, and deep cleaning through a pre-rinsing unit with irregularly shaped multi-pipes, an ultrasonic fine cleaning unit, a chemical backwashing unit, and a micron-level aeration unit. This allows for high-quality, one-click cleaning of MBR membrane modules with varying degrees of fouling. The turbulence and mixing from micron-level aeration enhance the migration of chemical cleaning agents to the fouling layer and membrane surface, improving the contact efficiency and reaction rate of the agents. Similarly, the cavitation effect of ultrasound generates strong local shear forces, microfluidics, and shock waves on the membrane surface, promoting the penetration of chemical cleaning agents into the fouling layer. In summary, the synergistic cleaning of chemical agents, ultrasound, and microbubbles not only further removes surface contaminants from the MBR membrane but also cleans contaminants within the pores of the MBR membrane fibers. The flux recovery of the MBR membrane module is superior to conventional manual cleaning. Finally, this integrated, multi-functional MBR membrane module cleaning equipment can clean MBR membrane modules of standard sizes, demonstrating versatility. Furthermore, it allows for the immediate hoisting of MBR membrane modules for cleaning, reducing the risk of MBR membrane caking, improving stable operating flux, and extending the service life and offline cleaning cycle of the MBR membrane.

The irregular multi-pipe pre-rinsing unit 3 is connected to the robot connector 303 through the irregular multi-pipe connected to the end of the robotic arm 203. The irregular multi-pipe main water inlet pipe connector 302 is connected to the irregular multi-pipe main water inlet pipe 301. The rinsing water in the irregular multi-pipe pre-rinsing unit 3 flows out through the irregular multi-pipe opening 306 in the irregular multi-pipe horizontal pipe 304 and the irregular multi-pipe vertical pipe 305.

[0013] When the integrated multi-functional MBR membrane module cleaning equipment is in operation, the MBR membrane module is completely disassembled from the MBR membrane tank and hoisted into the cleaning water tank unit 1. The robot moving unit 2, the irregularly shaped multi-pipe pre-rinsing unit 3, the sludge discharge unit 8 at the bottom of the cleaning water tank, the chemical dosing backwash unit 5, the clean water rinsing unit 6, the ultrasonic fine cleaning unit 4, the micron-level aeration unit 7, and the cleaning water recovery unit 9 are activated sequentially. The specific operation sequence is as follows: First, the robot moving unit 2 and the irregularly shaped multi-pipe pre-rinsing unit 3 are activated. Robot 202 drives the irregularly shaped multi-pipe pre-rinsing unit 3. The flushing water is sprayed through the opening 306 of the irregularly shaped multi-pipe and moves from top to bottom between the MBR membranes to a depth of 1800mm at a speed of 10cm / min. The opening (306) of the irregularly shaped multi-pipe has a diameter of 2mm. The sludge that has hardened between the MBR membranes falls to the bottom of the cleaning water tank unit 1 with the flushing water. After a single set of flushing is completed, it moves to the next set of MBR membranes for cleaning. The spacing of the irregularly shaped multi-pipe pre-flushing unit 3 can be randomly set by the robot 202, which can be spaced 2-8 MBR membranes apart. First, turn on the sludge discharge unit 8 at the bottom of the cleaning water tank unit 1. The flushing water in the sludge flushing nozzle 801 washes away the concentrated sludge liquid, flows through the sludge collection tank 802 at the bottom of the cleaning water tank, and flows into the sludge discharge pipe 106, where it is discharged by the sludge discharge pump 803. Then, turn on the chemical dosing backwash unit 5 and the clean water flushing unit 6. The clean water flushes the surface of the MBR membrane fibers, while the chemicals are backwashed into the MBR membrane fibers by the chemical dosing pump. Once the overall liquid level exceeds the top of the MBR membrane, turn off the clean water flushing unit 6 and the chemical dosing backwash unit 5. Finally, turn on the ultrasonic fine cleaning unit 4 and the micron aeration unit 7. The cleaning agent reacts fully with the contaminants on and inside the MBR membrane fibers, deeply removing contaminants. After 1 hour of reaction, the ultrasonic cleaning unit 4 and the micron aeration unit 7 are stopped. Finally, the cleaning water recovery unit 9 is turned on, and the cleaning water in the MBR membrane tank is pumped out through the cleaning water recovery pump 903 and returned to the cleaning water recovery tank 901. This cleaning water is used for the clean water rinsing unit of the next set of MBR membrane modules. The entire cleaning time is about 3 hours, and only one person is needed to operate the equipment and conduct inspections. After cleaning, the MBR membrane module is hoisted into the MBR membrane tank to produce water.

The remaining operating steps and times are the same as in Example 1.

[0015] Example 3 Taking the automated cleaning of a 40-piece / set MBR membrane module as an example, such as Figure 1-4The integrated multifunctional MBR membrane module cleaning equipment shown in the figure does not activate the ultrasonic fine cleaning unit 4 during operation. The rest of the operation sequence and time are the same as in Example 1.

[0016] Example 4 Taking the automated cleaning of a 40-piece / set MBR membrane module as an example, such as Figure 1-4 The integrated multifunctional MBR membrane module cleaning equipment shown does not activate the chemical dosing backwash unit 5 during operation. The rest of the operating sequence and time are the same as in Example 1.

The rest of the operation sequence and time are the same as in Example 1.

[0018] Application effect comparison

[0019] Therefore, it can be seen that compared with Comparative Example 1, Example 1 of this application saves about 60% of labor, shortens the cleaning time by 50%, and the transmembrane pressure difference after cleaning is significantly lower than that of manual cleaning, and the subsequent operation duration is extended by 2 months. Stopping some functions in this application, such as stopping the robot moving unit 2 and the irregular multi-tube pre-rinsing unit 3 in Example 2, stopping the ultrasonic fine cleaning unit 4 in Example 3, stopping the chemical backwashing unit 5 in Example 4, and stopping the micron aeration unit 7 in Example 5, cannot achieve the technical effect of manual cleaning, let alone the technical effect of this application.
