Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of MBR membrane module structure, comprise some filtering membrane silks 1 that evenly are spaced on the fixed support, the top of filtering membrane silk 1 connects upper putamina 2, the bottom of filtering membrane silk 1 is provided with lower shell 3, filtering membrane silk 1, upper putamina 2 and lower shell 3 are arranged in the filter screen pocket 4, and the bottom of filter screen pocket 4 and lower shell 3 link together, and form water stream channel 5 between the outer wall of adjacent two filter screen pockets 4.
MBR membrane module structure of the present utility model, the open top of described filter screen pocket 4.
