In this embodiment, the flat ceramic membrane element is firmly and quickly fixed in the rectangular cylindrical structure formed by the left fixing member, the front connecting member, the right fixing member and the rear connecting member, and its movement in the up and down, left and right, front and back directions is restricted; when the flat ceramic membrane element needs to be replaced, the corresponding operation can be carried out after removing the left blocking member; at the same time, the right blocking member can also provide certain auxiliary support to the right supporting part, thereby improving the stability of the structure.

[0069] The flat ceramic membrane filtration unit 100 also includes a water collecting pipe assembly 180, which is located on the upper part of one side of the left fixing member 120 and / or the right fixing member 130; if water outlet interfaces 114 are provided at both ends of the length direction of the flat ceramic membrane element 110, two sets of water collecting pipe assemblies 180 are provided, or one of the two water outlet interfaces 114 is blocked with a plug, and one set of water collecting pipe assemblies 180 is used; if a water outlet interface 114 is provided at one end of the length direction of the flat ceramic membrane element 110, one set of water collecting pipe assemblies 180 is used.

Figure 8 Schematic diagram of the structure of the membrane tower in Example 2, wherein only one set of water collecting pipe components is shown for the flat ceramic membrane filtration unit. Figure 8As shown in the figure, four flat ceramic membrane filter units 100 are stacked and combined. Due to the restrictions of the left limiter 125 and the right limiter 135, as well as the two water pipe fixings 181, the flat ceramic membrane filter unit 100 is not easy to move horizontally during the installation process. At the same time, in the adjacent flat ceramic membrane filter units 100, the bottom wall of the box of the upper left fixing 120 and the top wall of the box of the corresponding lower left fixing 120 are connected by bolts, and the bottom wall of the box of the upper right fixing 130 and the top wall of the box of the corresponding lower right fixing 130 are connected by bolts, which can further improve the reliability of the membrane tower structure.
