MBR membrane positioning assembly

The utility model discloses an MBR (Membrane Biological Reactor) membrane positioning component which comprises an MBR membrane, a support rod and a fastener, a plurality of flexible positioning teeth are uniformly arranged on one side of the support rod facing the MBR membrane, the MBR membrane is clamped among the flexible positioning teeth, a through hole is vertically formed in the middle of each flexible positioning tooth, and the fastener is fixedly connected with the support rod. The fastener comprises a connecting plate and a rigid inserting strip arranged at the lower end of the connecting plate, the connecting plate is fixed to the supporting rod, and the rigid inserting strip is inserted into the through hole. The MBR membrane fixing device has the beneficial effects that rigid connection is avoided through the flexible positioning teeth, the through holes are correspondingly formed in the flexible positioning teeth and used for being matched with the rigid insertion strips, and the flexible positi
