Abstract

The present invention discloses a ceramic membrane assembly, including a membrane shell tube, a membrane element assembly arranged inside the membrane shell tube, two flanges fixed at both ends of the membrane shell tube, a sealing disk arranged outside the flange, and a pressure plate for fixing the sealing disk on the flange. A filtrate outlet is provided on the side wall of the membrane shell tube, the membrane element assembly is composed of a plurality of membrane elements, and a through flow channel assembly is provided inside the membrane element along the axial direction. All membrane elements are arranged in a honeycomb shape, a plurality of first through holes are provided on the sealing disk, and the two ends of the membrane element pass through the two flanges and extend into the first through hole respectively. The outer wall surface of the membrane element is sealed with the inner wall of the first through hole, and a plurality of second through holes corresponding to the positions of the first through holes are provided on the pressure plate. The present invention also discloses a ceramic membrane system including the above-mentioned ceramic membrane assembly. The ceramic membrane assembly of the present invention has a small volume, a large packing density, a compact structure, and a low cost, and is suitable for the low-cost sewage treatment field and the filtration separation field.
