Fixing assembly for MBR membrane

The utility model provides a fixing component for an MBR (membrane bioreactor) membrane, which comprises a sawtooth-shaped pressing strip body and a pinch plate for fixing the sawtooth-shaped pressingstrip body, the pinch plate is a 304 stainless steel plate body, and the section of the pinch plate is chair-shaped. According to the utility model, the cross section of the pinch plate is changed into a chair shape, and a stainless steel strip does not need to be welded on the edge of the pinch plate to prevent the sawtooth-shaped depression bar body from slipping, so that deformation of the pinch plate during welding and deformation during later use are avoided, a sawtooth-shaped depression bar body membrane element can be better fixed, and the stability of the membrane element is improved. 本实用新型提供了一种MBR膜用固定组件，包括锯齿形压条本体和固定锯齿形压条本体的扣板，所述扣板为304不锈钢板体且扣板的截面为椅子状。本实用新型中将扣板的截面变成椅子状，不用在扣板边再焊接不锈钢条来阻止锯齿形压条本体滑脱，避免了扣板在焊接时产生的变形以及后期使用中的变形，能更好的固定锯齿形压条本体机膜元件，增加了膜元件的稳定性。
