At least two separating ribs 12 are positioned in the flow guide space and intersect with the inner wall surface of the ceramic membrane shell 11 to correspondingly separate the flow guide space into flow guide channels 15 arranged in parallel. The flat ceramic membrane 10 further includes at least one first water outlet 13 and at least one second water outlet 14 penetrating the ceramic membrane housing 11 and distributed at intervals, each first water outlet 13 is at least communicated with two or more adjacent flow guide channels 15 to form a first flow guide area, each second water outlet 14 is at least communicated with two or more adjacent flow guide channels 15 to form a second flow guide area, and the first flow guide area and the adjacent second flow guide area are partially overlapped and/or arranged at intervals.

The ceramic membrane shell 11 forms a hollow thin-walled structural member, and the partition ribs 12 intersect with the wall surface of the flow guide space and provide a supporting force for the ceramic membrane shell 11 to stabilize the structural shape and size of the flat ceramic membrane 10. Alternatively, the ceramic membrane housing 11 and the separation ribs 12 are integrally formed and processed by a ceramic sintering process, and accordingly, the ceramic membrane housing 11 and the separation ribs 12 are made of the same or similar materials. Optionally, the separation ribs 12 are distributed in parallel in the diversion space, and correspondingly, the diversion channels 15 formed by separation of the separation ribs 12 are parallel to each other. Alternatively, the spacing of the separation ribs 12 is the same, and accordingly, the cross-sectional width dimension of the flow guide channel 15 is the same.

The ceramic membrane shell 11 has one or more first outlet holes 13 and second outlet holes 14 on its surface, and each of the first outlet holes 13 and the second outlet holes 14 can communicate with one or more flow guide channels 15. For example, a first outlet hole 13 penetrates the ceramic membrane housing 11 and cuts off one or more partition ribs 12 located at the position, so that the flow guide channels 15 partitioned by the partition ribs 12 are all communicated with the first outlet hole 13 to form a first flow guide area. Alternatively, the first outlet hole 13 may cut off the two separating ribs 12 at the same time, so that three flow guide channels 15 separated by the two separating ribs 12 are communicated to the first outlet hole 13, and the liquid in the three flow guide channels 15 may be discharged through the first outlet hole 13. Similarly, a second outlet hole 14 penetrates through the ceramic membrane housing 11 and cuts off one or more than one separating ribs 12 located at the position, so that the flow guide channels 15 separated by the separating ribs 12 are all communicated with the second outlet hole 14 to form a second flow guide area.

Meanwhile, the flow guide channels 15 at the edges of the first flow guide area and the adjacent second flow guide area are overlapped, liquid in the first flow guide area can flow out through the second flow guide area, the liquid flows unsmoothly after the first water outlet hole 13 or the second water outlet hole 14 is blocked, and the flow guide effect is good.

The ceramic membrane housing 11 has a plate-like structure similar to a rectangular parallelepiped, and the first side wall 1111 and the second side wall 1112 form a rectangular edge surrounding the flat plate wall 112. The first side wall 1111 is located in the longitudinal direction of the ceramic membrane housing 11, and the partition ribs 12 are parallel to the first side wall 1111 so that the flow guide channels 15 extend along the longitudinal direction of the ceramic membrane housing 11. Alternatively, the plate wall 112, the first side wall 1111 and the partition rib 12 are formed by an extrusion molding process, and the second side wall 1112 is closed at the rectangular opening. Accordingly, the partition ribs 12 intersect with the second side wall 1112 to form the corresponding flow guide channels 15, and the processing is convenient. After the ceramic membrane shell 11 is integrally formed into a closed structure, the ceramic membrane shell is processed into the flat ceramic membrane 10 by sintering and other processes, and the processing efficiency is high.

The ribs 16 serve to increase the structural stability of the ceramic membrane housing 11 and are located close to the inner side walls of the ceramic membrane housing 11. Alternatively, the ribs 16 are distributed on both sides of the transverse center axis of the ceramic membrane housing 11, i.e. the ribs 16 are located near the edge region of the ceramic membrane housing 11. The reinforcing ribs 16 may be formed in the same shape and size as the partition ribs 12, or in different shapes and sizes.
