[0016] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0017] The present utility model discloses a bundled hollow fiber ceramic membrane, which includes a housing, two flow guiding covers, a plurality of filter elements 1 and two sealing ends 2. The two flow guiding covers are embedded and fixed at both ends of the housing along the length direction, as Figure 1 shown. The two sealing ends 2 are fixedly connected to both ends of the filter element 1 along the length direction. The filter element 1 and the sealing ends 2 are located inside the housing. The filter element 1 and the sealing ends 2 are located between the two flow guiding covers. The filter element 1 is in a polygonal column shape, preferably a 16-sided shape.

[0018] As Figure 2 shown, the sealing end 2 includes a raw water area 21 and a product water area 22. The product water area 22 is located at the outer edge of the sealing end 2 along the circumferential direction. The product water area 22 is surrounded by the raw water area 21. Both ends of the filter element 1 along the length direction are fixedly connected to the product water area 22. The filter element 1 is uniformly distributed in the product water area 22 in a bundled structure.

[0019] As Figure 3 shown, each filter element 1 is provided with a plurality of raw water channels 11 running through along the length direction. The raw water channels 11 are uniformly distributed inside the filter element 1. The raw water area 21 is provided with a plurality of through holes 23. The through holes 23 are arranged corresponding to the raw water channels 11. Each filter element 1 is provided with 18 - 20 raw water channels 11 running through along the length direction.
