Description

Technical Field

[0001] This utility model relates to the field of MBR offline sludge flushing tank technology, and in particular to an integrated device for MBR offline cleaning tank. Background Technology

[0002] Membrane bioreactor (MBR) technology is a novel wastewater treatment technology that combines membrane separation technology with biological treatment processes. Membrane fouling is unavoidable during membrane separation. Once the membrane is fouled, it will increase transmembrane resistance, reduce membrane flux, and affect the membrane's performance and lifespan. Therefore, it is often necessary to perform cleaning operations through online or offline sludge flushing tanks in the MBR.

[0003] The MBR membrane offline cleaning process mainly includes the following steps:

[0004] First, stop the suction pump and blower. Close the outlet valve, then disconnect the union or flange interfaces of the water collection pipe and external aeration pipe on the MBR membrane module and remove the MBR membrane module. Rinse the surface of the MBR membrane with tap water to remove sludge. Determine the type of fouling based on the feel of the membrane module: a sticky residue indicates organic fouling, while stiff, rough membrane fibers indicate inorganic fouling. Estimate the amount of chemical cleaning solution based on the number of membrane modules and prepare the chemical cleaning solution according to the type of fouling. Place the MBR membrane module in the chemical soaking tank with the prepared cleaning solution and soak for 6-12 hours. Stir the solution periodically during soaking. After soaking, rinse the MBR membrane module with clean water until the pH is neutral. Lift the neutralized MBR membrane module back into the MBR membrane bioreactor and reconnect the union or flange interfaces of the water collection pipe, internal aeration main pipe, and external aeration pipe. Turn on the blower, increase the air volume, and purge the membrane module for 5-10 minutes. Then adjust the air volume to normal, turn on the suction pump, and switch to normal automatic operation mode.

[0005] Regarding the aforementioned technologies, it has been found that existing MBR offline cleaning processes require rinsing with tap water. However, traditional water pipe rinsing methods are prone to incomplete cleaning and low cleaning efficiency. Furthermore, during the soaking process in the chemical soaking tank, uneven distribution of the chemicals can easily occur, thus affecting the cleaning effect. Utility Model Content

The suspension assembly 10 is installed above the sludge flushing tank 1 and the chemical soaking tank 9 to transfer the MBR membrane from the sludge flushing tank 1 to the chemical soaking tank 9, ensuring a stable transfer to the chemical soaking tank 9 after the MBR membrane has been flushed with sludge. Two sets of pallet frames 2 are symmetrically installed on the upper surface of the sludge flushing tank 1, and the pallet frames 2 are fixedly connected to the sludge flushing tank 1. Equipment supports are fixedly installed in the sludge flushing tank 1. The frame 3 and the outer side of the sludge washing tank 1 are fixedly installed with a drive component 4 that drives the equipment support 3 to flip. The head of the equipment support 3 is fixedly installed with an arc-shaped support plate 5, and the lower end of the equipment support 3 is provided with a holding component 6.

The bottom inner side of the sludge washing tank 1 is also fixedly installed with a washing component 8. Several stirring components 91 are also installed in the chemical soaking tank 9. The stirring components 91 are set to ensure that the chemical solution is stirred regularly to ensure that the chemical solution is in uniform contact with the MBR membrane. By symmetrically installing two sets of pallet frames 2 on the upper surface of the sludge washing tank 1, the equipment bracket 3 can be supported by the two sets of pallet frames 2 during use. After the two ends of the equipment bracket 3 are installed on the pallet frames 2, the angle can be adjusted by flipping it using the drive component 4. At the same time, by fixing an arc-shaped pallet 5 on the upper part of the equipment bracket 3, the design of the arc-shaped pallet 5 facilitates the placement of the membrane to be cleaned and supports the membrane, making it easier to perform the washing process. By setting a horizontally sliding pressing component 6 at the lower end of the equipment bracket 3, when the membrane to be cleaned is placed on the arc-shaped pallet 5, the pressing component 6 can be moved by the electric cylinder 7 to press and fix it, thereby ensuring stable cleaning of the membrane.

The cylindrical rod 31 is rotatably mounted on the pallet frame 2, and the end brackets 32 are fixedly mounted on both ends of the cylindrical rod 31. By designing the equipment bracket 3 with a structure in which the cylindrical rod 31 and the end brackets 32 cooperate, it is possible to suspend the arc-shaped pallet 5 through the end brackets 32 at both ends during use. Connecting shafts 311 are integrally formed at both ends of the cylindrical rod 31. The diameter of the connecting shafts 311 is smaller than the diameter of the cylindrical rod 31. A positioning groove 21 is provided at the head of the pallet frame 2 for the connecting shafts 311 to be rotatably mounted. By integrally forming the connecting shafts 311 at both ends of the cylindrical rod 31, the equipment bracket 3 can be rotatably mounted in the positioning groove 21 during installation, ensuring better tilting and adjustment.

The lower end face of the end bracket 32 ​​is provided with a positioning seat 321 for sliding installation of the horizontal frame 61, and the positioning seat 321 is fixedly connected to the end bracket 32. By fixing the positioning seat 321 to the lower end face of the end bracket 32, it is convenient to slide the horizontal frame 61 through the positioning seat 321 during use.

[0033] Reference Figure 2 As shown, the rinsing assembly 8 includes a water pump 81, a water supply pipe bracket 82, and a diversion nozzle 83. The lower end of the water supply pipe bracket 82 is installed at the output port of the water pump 81, and the diversion nozzle 83 is installed at the head of the water supply pipe bracket 82. The structure of the rinsing assembly 8 is designed to ensure that the water pump 81 can supply water to the diversion nozzle 83 through the water supply pipe bracket 82 during use, and thus the membrane can be rinsed by the diversion nozzle 83.

[0034] In this embodiment, when cleaning is required, the equipment bracket, drive unit, arc-shaped support plate, pressing component, electric cylinder and flushing component are assembled together. The assembled integrated device is a whole. When installation is required, it is placed directly in the sludge flushing tank, and the connecting shafts at both ends of the equipment bracket are inserted into the positioning grooves of the support plate frame. Then, the motor base is fixedly installed on the sludge flushing tank with bolts for normal use.

[0035] When the MBR membrane needs to be rinsed, a single MBR membrane is suspended and placed onto an arc-shaped support plate using a suspension assembly. Then, an electric cylinder is activated to move the holding assembly, which is then held in place by the arc-shaped pressure plates at both ends. Once the membrane is securely held, the water pump can be started for rinsing. During rinsing, the membrane can be rotated using a drive motor to facilitate rinsing different areas. After rinsing, the MBR membrane is lifted using the suspension assembly and placed into a chemical soaking tank for immersion. During immersion, the agitation assembly is continuously used to ensure a better immersion effect for the MBR membrane.
