[0002] Existing tubular ceramic membranes have certain limitations during use, such as low filtration efficiency, limited anti-pollution ability, and difficulty in cleaning. Compared with organic membranes, traditional ceramic membranes have the problem of low loading density of membrane elements per unit volume, which directly affects the filtration area and filtration efficiency. Therefore, in order to improve the filtration performance and service life of ceramic membranes, it is urgent to develop a new type of ceramic membrane structure to improve its specific surface area and loading density.
