[0022] The upper pressure structure includes a mounting top plate 2 mounted on the top of the mounting outer frame 1, and a plurality of fixed through-slots 6 are provided on the mounting top plate 2, each fixed through-slot 6 corresponding to a group of fixed plates 3, and a connecting plate 9 is fixedly connected to the outside of each fixed through-slot 6, and an adjusting plate 10 is fixedly connected to the top of the plurality of connecting plates 9. The inner side of each fixed through-slot 6 is slidably connected to an upper pressing plate 7, and the top of each upper pressing plate 7 is rotatably connected to an adjusting screw 11, each adjusting screw 11 is arranged through the adjusting plate 10, and each adjusting screw 11 is threadedly connected to the adjusting plate 10. When the adjusting screw 11 rotates, it moves up and down under the action of the thread, thereby driving the upper pressing plate 7 to move together, and adjusting the position of the upper pressing plate 7 so that the upper pressing plate 7 is pressed on the upper end of the MBR membrane, thereby completing the fixation of the MBR membrane and the sealing of the device;

[0023] A sliding groove 13 is provided on the side wall of each fixed plate 3, and each mounting plate 4 is slidably connected to the inner wall of the sliding groove 13. A connecting spring 14 is fixedly connected to the side wall of each mounting plate 4, and one end of each connecting spring 14 away from the mounting plate 4 is fixedly connected to the inner side wall of the corresponding sliding groove 13. Each mounting plate 4 is extended to the outside of the fixed plate 3, and a mounting groove 5 is provided on the side wall of each mounting plate 4 located on the outer part of the fixed plate 3. When the mounting plate 4 is moved to both sides, the connecting spring 14 contracts and the MBR membrane is set to the mounting groove 5 on the mounting plate 4. The outer frame of the MBR membrane is attached to the inner wall of the mounting groove 5. Under the action of the elastic force of the connecting spring 14, the mounting plates 4 on both sides fix the MBR membrane.

[0024] Each upper pressing plate 7 is provided with an adjustment groove inside, and an extension plate 8 is slidably connected to the inside of each adjustment groove, and the extension plates 8 are arranged on the left and right sides of the adjustment groove. Each extension plate 8 extends to the outside of the corresponding upper pressing plate 7, and the shape of the extension plate 8 corresponds to the installation groove 5. When the extension plate 8 moves outward, the extension plate 8 moves to the position corresponding to the installation plate 4, so that the extension plate 8 can block the gap between the installation groove 5 and the MBR membrane to prevent sewage from flowing out.

[0025] The bottom end of the mounting top plate 2 is fixedly connected with a fixing block, and the top end of the mounting outer frame 1 is provided with a fixing slot. The mounting outer frame 1 and the mounting top plate 2 are connected together through the fixing block and the fixing slot, making the disassembly between the mounting top plate 2 and the mounting outer frame 1 easier;

[0026] The top of each adjusting screw 11 is fixedly connected to a rotating disk 12, and the outside of each rotating disk 12 is wrapped with a rubber protective layer. Rotating the rotating disk 12 rotates the adjusting screw 11, and the rubber protective layer facilitates the rotation of the rotating disk 12; the shape of each fixed plate 3 and the mounting plate 4 corresponds to the mounting outer frame 1, preventing sewage from flowing out from the gaps in the mounting outer frame 1 and the mounting plate 4.

[0027] When the adjusting screw 11 is rotated, the adjusting screw 11 will move up and down when it rotates, thereby driving the upper pressure plate 7 to move together, and adjusting the position of the upper pressure plate 7 so that the upper pressure plate 7 is pressed against the upper end of the MBR membrane. Then, the extension plate 8 is moved outward, and the extension plate 8 is moved to the position corresponding to the installation plate 4, so that the extension plate 8 can block the gap between the installation groove 5 and the MBR membrane, preventing sewage from flowing out, thereby completing the fixation of the MBR membrane and the sealing of the device.
