However, the unique water treatment process determines that the MBR membrane group needs to be replaced frequently, and basically the MBR membrane group needs to be replaced after the equipment runs for one or two years. The traditional installation and disassembly method is more troublesome, and the fixing problem after installation is also more complicated, especially the installation and disassembly after rusting of the equipment in the later period will waste a lot of cost and time. Therefore, it is necessary to design a structure to solve the coupling problem of the MBR membrane group. SUMMARY

[0013] Further, a limiting ring is arranged at the upper end of the vertical screw rod, the limiting ring is located on the inner side of the pressing plate, and the limiting ring is arranged on the vertical screw rod through a pin. The limiting ring serves to limit the vertical screw rod and the pressing plate.

[0014] Further, the pressing plate is concave, which facilitates the taking out of the MBR membrane group.
