Against this backdrop, membrane separation technology has emerged and, due to its unique advantages, has gradually become a key technology in the field of wastewater treatment. Membrane separation technology refers to the selective separation of mixtures of molecules of different particle sizes at the molecular level when passing through a semi-permeable membrane.

[0025] See Figures 1-5This application provides a wastewater treatment filtration membrane module device using membrane separation technology, including a support base 2, a filtration membrane module, a pressure base 10, and a locking component disposed within a wastewater treatment tank 1. The support base 2 is fixedly installed on the bottom inner wall of the wastewater treatment tank 1. A drainage chamber 3 is provided inside the support base 2. Multiple evenly distributed slots 4 are provided on the top of the support base 2. Through holes 5 communicating with the drainage chamber 3 are provided on the bottom inner wall of each slot 4. The pressure base 10 is located directly above the support base 2. An inlet chamber 11 is provided inside the pressure base 10. Multiple evenly distributed slots 12 are provided on the bottom of the pressure base 10. Through holes 13 communicating with the inlet chamber 11 are provided on the top inner wall of each slot 12. The filtration membrane module includes multiple filter cylinders 6. The bottom ends of the multiple filter cylinders 6 are slidably installed in corresponding slots 4, and the top ends of the multiple filter cylinders 6 are slidably installed in corresponding slots 12. Microfiltration membranes 7 are fixedly installed in the filter cylinders 6 from top to bottom. The ultrafiltration membrane 8, nanofiltration membrane 9, and reverse osmosis membrane 32, installed within the filter cartridge 6, form a multi-layer filtration system. The microfiltration membrane 7 has a pore size range of 0.1-10 micrometers and is primarily used to filter and remove suspended solids, colloids, and bacteria from wastewater. The ultrafiltration membrane 8 has a pore size range of 0.001-0.1 micrometers and is primarily used to filter and remove larger molecular weight substances such as cells, proteins, and residual organic matter from wastewater. The nanofiltration membrane 9 has a pore size below 0.001 micrometers and is primarily used to filter and remove salt, hardness, and organic matter from wastewater. The reverse osmosis membrane 32 has a pore size range of 0.0001-0.001 micrometers and is primarily used to filter and remove ions, chemicals, and bacteria from wastewater. Through the synergistic effect of these multiple membranes, the system efficiently intercepts pollutants of different particle sizes, including suspended solids, colloids, large organic molecules, and bacteria, significantly improving wastewater treatment quality.

[0026] In this embodiment, the locking assembly is used to lock and fix the filter membrane assembly between the support seat 2 and the pressure seat 10. The locking assembly includes two upper connecting blocks 14, two vertical rods 15, two lower connecting blocks 16, two upper stops 17, two trapezoidal abutments 19, and two springs 20. The two upper connecting blocks 14 are fixedly installed on the outer side wall of the pressure seat 10 and are symmetrically distributed. The two vertical rods 15 are respectively fixedly installed on the bottom of the corresponding upper connecting blocks 14. The two lower connecting blocks 16 are respectively fixedly installed on the outer side wall of the support seat 2 and are symmetrically distributed. The top of the two lower connecting blocks 16 is provided with a through mounting hole. The bottom ends of the two vertical rods 15 slide through the corresponding mounting holes. The two upper stops 17 are respectively fixedly installed on the side of the two vertical rods 15 that is far apart from each other. The two upper stops 17 abut against the top of the corresponding lower connecting blocks 16. The side of the two vertical rods 15 that is far apart from each other is provided with a groove 18. The two trapezoidal abutments 19 are respectively slidably installed in the corresponding groove 18. The two trapezoidal blocks 19 extend to the corresponding grooves 18 on the opposite side. They abut against the bottom of the corresponding lower connecting blocks 16. The thickness of the trapezoidal blocks 19 decreases from top to bottom. Two springs 20 are fixedly installed on the sides of the two trapezoidal blocks 19 that are close to each other. The ends of the two springs 20 that are close to each other are fixedly connected to the inner walls of the sides of the two grooves 18 that are close to each other. By tightly abutting the bottom surface of the trapezoidal blocks 19 and the top surface of the lower connecting blocks 16 with the upper stop 17, the filter membrane assembly can be firmly locked between the support seat and the pressure seat. This structural design is simple and reliable. It can effectively prevent the filter membrane assembly from loosening or shifting due to water flow impact, vibration and other factors during sewage treatment. It can ensure the stability and safety of the device operation. Moreover, when installing and disassembling the filter membrane assembly, only external force needs to be applied to the trapezoidal blocks 19 to overcome the elastic force of the springs 20. The installation and disassembly of the filter membrane assembly can be easily realized. The operation is convenient.

[0027] In this embodiment, a horizontal guide rod 21 is fixedly installed on the side of each of the two trapezoidal blocks 19 that are close to each other. The horizontal guide rod 21 is located above the spring 20. A fixing plate 22 is fixedly installed on the top inner wall of each of the two grooves 18. A guide hole is opened through one side of each of the two fixing plates 22. The ends of the two horizontal guide rods 21 that are close to each other slide through the corresponding guide holes. By utilizing the sliding connection between the horizontal guide rod 21 and the guide hole on the fixing plate 22, the movement direction when pressing the trapezoidal block 19 can be guided to ensure that the trapezoidal block 19 moves smoothly and stably in a horizontal straight line.

[0028] In this embodiment, a damping ring 23 is fixedly installed on the inner wall of slot 1 4. The bottom outer wall of the filter cylinder 6 makes damping sliding contact with the inner ring wall of damping ring 23. A damping ring 24 is fixedly installed on the inner wall of slot 2 12. The top outer wall of the filter cylinder 6 makes damping sliding contact with the inner ring wall of damping ring 24. The design of damping ring 23 and damping ring 24 ensures that the filter cylinder 6 can be flexibly installed and disassembled, while effectively enhancing the sealing of the connection. This prevents sewage from leaking from the gap between the filter cylinder 6 and slot 1 4 and the gap between the filter cylinder 6 and slot 2 12 during the filtration process, ensuring that all sewage is treated by the filter membrane assembly and improving the reliability of the sewage treatment effect. At the same time, damping ring 23 and damping ring 24 can also play a certain positioning and buffering role for the filter cylinder 6, reducing the shaking of the filter cylinder 6 under the impact of water flow and extending the service life of the filter cylinder 6.

[0029] In this embodiment, a guide pipe 25 is fixedly installed on the top of the water inlet chamber 11, and the guide pipe 25 is connected to the water inlet chamber 11. A sewage inlet pipe 26 is fixedly installed on the top of the sewage treatment cabinet 1, and the bottom end of the sewage inlet pipe 26 extends into the guide pipe 25. The sewage inlet pipe 26 is used to transport sewage into the guide pipe 25, so that the sewage enters the water inlet chamber 11 through the guide pipe 25, so as to facilitate subsequent sewage filtration and purification treatment. It also allows the guide pipe 25 to have space to move upward, so as to smoothly push the pressure seat 10 and the guide pipe 25 upward, which facilitates the disassembly and assembly of the filter membrane assembly.

[0030] In this embodiment, a sealing ring 27 is fixedly sleeved on the sewage inlet pipe 26. The outer ring of the sealing ring 27 slides and seals against the inner wall of the guide pipe 25. The design of the sealing ring 27 can seal the gap between the sewage inlet pipe 26 and the guide pipe 25, preventing sewage from flowing out from the gap between the sewage inlet pipe 26 and the guide pipe 25.

[0031] In this embodiment, a drain pipe 28 is fixedly installed on one side of the support 2. One end of the drain pipe 28 extends into the drain cavity 3, and the other end of the drain pipe 28 extends outside the sewage treatment cabinet 1. The drain pipe 28 is designed to discharge the sewage after filtration and purification.

[0032] In this embodiment, an inspection port is provided on the front side of the sewage treatment cabinet 1. A sealing door 29 is fixed to the outer front wall of the sewage treatment cabinet 1 by screws. The sealing door 29 is adapted to the inspection port. The design of the sealing door 29 and the inspection port facilitates the inspection and maintenance of the inside of the sewage treatment cabinet 1.

[0033] In this embodiment, a plurality of evenly distributed fixed columns 30 are fixedly installed at the bottom of the support base 2, and the same stabilizing plate 31 is fixedly installed at the bottom end of the plurality of fixed columns 30. The top of the stabilizing plate 31 is provided with a plurality of evenly distributed clearance holes, and the plurality of filter cylinders 6 slide through the corresponding clearance holes respectively. The design of the plurality of fixed columns 30 and the stabilizing plate 31 further enhances the stability of the filter membrane assembly during use.

[0034] With the above structure, the wastewater treatment filtration membrane module device using membrane separation technology provided in this application allows wastewater to flow into the guide pipe 25 through the wastewater inlet pipe 26, and then into the inlet chamber 11 through the guide pipe 25. The sealing ring 27 ensures the seal between the wastewater inlet pipe 26 and the guide pipe 25, preventing wastewater leakage. The wastewater entering the inlet chamber 11 flows into the corresponding filter cartridge 6 through multiple through holes 13. After entering the filter cartridge 6, the wastewater passes through the microfiltration membrane 7, ultrafiltration membrane 8, nanofiltration membrane 9, and reverse osmosis membrane 32 in sequence. The microfiltration membrane 7 is used to intercept and filter suspended solids, colloids, and other particles in the wastewater. Large particulate pollutants are filtered by ultrafiltration membrane 8 to intercept and filter large molecules such as cells, proteins, and residual organic matter in wastewater; nanofiltration membrane 9 to filter and remove salt, hardness, and organic matter in wastewater; and reverse osmosis membrane 32 to intercept and filter small molecules such as ions, chemicals, and bacteria in wastewater. Through the four-stage membrane process, the wastewater is purified in a deep chain by filtering pollutants of different particle sizes. The purified water after filtration by the four-stage membrane flows into the drainage chamber 3 of the support seat 2 through the through hole 5 at the bottom of the filter cartridge 6, and finally is discharged from the wastewater treatment tank 1 through the drainage pipe 28, completing the entire wastewater filtration and purification process.

[0035] When it is necessary to disassemble the filter membrane assembly, first remove the sealing door 29, then press the two trapezoidal blocks 19 so that the two trapezoidal blocks 19 slide into the corresponding grooves 18 respectively, so that they overcome the elastic force of the spring 20, thereby releasing the contact state between the trapezoidal blocks 19 and the bottom of the lower connecting block 16. Then the pressure seat 10 can be easily moved upward, so that the vertical rod 15 can be pulled out from the mounting hole of the lower connecting block 16. At this time, the pressure seat 10 will also drive the guide tube 25 to move upward. Then, multiple filter cartridges 6 can be pulled out one by one to complete the disassembly of the filter membrane assembly. The operation is simple and quick, and it is convenient for subsequent cleaning, maintenance and replacement.

[0036] When installing the filter membrane assembly, align the bottom ends of multiple filter cartridges 6 with the slots 4 on the top of the support 2 and insert them. At this time, the outer wall of the bottom of the filter cartridge 6 makes damping sliding contact with the inner ring wall of the damping ring 23, which serves to position and seal the filter. Then, press down the pressure seat 10 and insert the top of the filter cartridge 6 into the corresponding slot 12. The outer wall of the top of the filter cartridge 6 makes damping sliding contact with the inner ring wall of the damping ring 24. As the pressure seat 10 descends, the two vertical rods 15 will gradually insert into the mounting holes on the corresponding lower connecting blocks 16. During this process, the trapezoidal... When the abutment 19 is squeezed, it will overcome the elastic force of the spring 20 and automatically slide into the groove 18. When the upper stop block 17 abuts against the top of the lower connecting block 16, the trapezoidal abutment 19 will also descend to the bottom of the lower connecting block 16. Under the elastic force of the spring 20, it will automatically push the trapezoidal abutment 19 out of the groove 18 for automatic reset. The trapezoidal abutment 19 and the bottom of the lower connecting block 16 will be tightly abutted, thus completing the secure locking of the filter membrane assembly between the support seat 2 and the pressure seat 10, realizing the simple and quick installation and fixing operation of the filter membrane assembly.
