[0034] Among them, the membrane assembly 5 includes a substrate 501 and a PTFE hydrophilic membrane 502 arranged on the left and right sides of the substrate 501.

The other end of the pull rod 505 passes through the right end of the fixed frame 503 and is rotatably connected to a connecting seat 507. The end of the connecting seat 507 away from the pull rod 505 is fixedly connected to a pressure block 508. The pressure block 508 abuts against the surface of the PTFE hydrophilic membrane 502 for fixing the PTFE hydrophilic membrane 502.

The bubbles generated by aeration can help remove dirt and biofilm on the membrane surface, reduce membrane pollution and blockage, and extend the service life of the membrane.

[0049] Working principle: Before use, connect the air source to the aeration main pipe 11 through the first connector 13, connect the water collection pipe 18 to the water collection device through the second connector 19, then pull the handle 506 outward to make the pressure block 508 compress the first damping spring 509 and move it in the direction of the handle 506.

At this time, under the action of the elastic force of the first damping spring 509, the pressing block 508 will press on the PTFE hydrophilic membrane 502 to fix it. Then press the pull block 9 to compress the second damping spring 8, thereby driving the second block 10 to move in the direction of the pull block 9. Then insert the sliding block 4 into the guide rail 3. When the second block 10 is aligned with the second slot 6, release the pull block 9. At this time, under the action of the second damping spring 8, the second block 10 will be stuck in the second slot 6 to fix the membrane assembly 5. After all the membrane assemblies 5 are installed on the membrane rack 1, the second connecting piece 5020 of one membrane assembly 5 is pulled close to the first connecting piece 5018 of another membrane assembly 5, and then the second connecting piece 5020 is rotated to connect the second connecting piece 5020 and the first connecting piece 5018 together.
