the upper crossbeam 9 is connected with a locking ring 13 for fixing the upper connecting body 6, the locking ring 13 comprises a movable ring 14 and a fixing ring 15 fixedly connected with the upper crossbeam 9, one end of the movable ring 14 is rotatably connected with one end of the fixing ring 15, the other end of the movable ring 14 is connected with the other end of the fixing ring 15 through a bolt and a nut, the upper connecting body 6 is connected with a pagoda joint 16 communicated with the inner cavity of the membrane body 4, the pagoda joint 16 is connected with a drainage device 17, and the drainage device 17 is communicated with the collecting pipe 2.

Specifically, the outer wall of the lower connecting body 5 is provided with a first groove 18, and the elastic clamping piece 11 is clamped on the outer wall of the first groove 18. When the elastic clip 11 is clamped in the first groove 18, the upper end of the elastic clip 11 abuts against the top wall of the first groove 18, so that the lower connecting body 5 and the elastic clip 11 are prevented from sliding downwards.

Specifically, the outer wall of the upper connecting body 6 is provided with a second groove 19, and the locking ring 13 is sleeved in the second groove 19. When the locking ring 13 is sleeved in the second groove 19, the top of the locking ring 13 abuts against the top wall of the second groove 19, so that the upper connecting body 6 and the locking ring 13 are prevented from sliding downwards relatively.

Specifically, drainage device 17 is including connecting plate 20 and connecting pipe 21, and connecting plate 20 can dismantle with outer frame 8 and be connected, and connecting plate 20 is connected with the connecting block 22 that is used for installing connecting pipe 21, and connecting pipe 21 one end is connected with pagoda joint 16, and the other end and the collecting pipe 2 of connecting pipe 21 are connected.

Through the arrangement, the installation and disassembly work of the MBR membrane group 3 and the bracket assembly 7 is simplified. Moreover, the mode that the lower extreme of MBR membrane group 3 is connected through elasticity clamping piece 11 with lower beam 10 has still avoided among the prior art bolt and nut long-term bubble in sewage, leads to bolt and nut to produce the corrosion, makes the difficult problem of dismantling of bolt.

When a new MBR membrane group 3 is replaced, the upper connecting body 6 is clamped into the fixed ring 15, the movable ring 14 is rotated, and the movable ring 14 and the fixed ring 15 are connected by bolts, so that the fixed ring 15 and the movable ring 14 are connected into a whole. And then the lower connecting body 5 is clamped into the elastic clamping pieces 11, so that the connection between the MBR membrane group 3 and the bracket assembly 7 is completed. And then the drainage device 17 is connected with the MBR membrane group 3, so that the MBR membrane group 3 is disassembled.
