Due to the large area of ​​the filter membrane, the sewage is partially evaporated and discharged through the filter membranes distributed on both sides of the main body 10, while the inner cavity between the two filter membranes is left with high-concentration sewage. The cycle is repeated for many times, thereby making the sewage concentration higher and higher, and more and more water vapor is discharged along the filter membrane. The whole filtering process has a large filtering area, a fast filtering speed, and a high processing efficiency. At the same time, it is easy to disassemble and install, and has a high maintenance efficiency.

[0034] Specifically, in the actual application process, a nanofiber membrane is arranged on the filter membrane to improve the filtering effect.

In actual use, since the operation of the pump tends to pull the filter membrane, long-term operation can easily cause the filter membrane to slightly deviate, affecting the filtering effect. By providing the compression strips 40, the problem of deviation is solved, ensuring long-term filtration. Specifically, the plurality of compression strips 40 are provided in parallel.

[0036] Preferably, the raised platform 123 is annular, and the recessed groove 124 matches the raised platform 123. The sewage filter sheet also includes a frame-type mounting structure 20, and the main body 10 is also provided with a frame-type mounting groove 16, the frame-type mounting groove 16 is distributed outside the middle through hole 11, the frame-type mounting structure 20 is fixedly mounted on the frame-type mounting groove 16, and the filter membrane is fixed on the frame-type mounting structure 20. The main body 10 is rectangular, and the suction end 12 is annular. The number of the suction end 12 and the suction end 13 is the same, and the number of the suction end 12 is two. The extension direction of the cylindrical through hole 122 is the same as the extension direction of the raised platform 123. A plurality of side mounting holes 14 are provided on the side of the main body 10.
