Such a structural arrangement allows water to enter the outer wall of each ceramic membrane element 6, effectively increasing the contact area between the ceramic membrane element 6 and the water, and between the water outlet positioning seal 5 and the shell 1 A first sealing ring 7 is provided in the middle, so that the housing 1 is divided into two cavities. The sewage flows below the water outlet positioning seal 5, is filtered by the ceramic membrane element 6, and then flows to the top of the water outlet positioning seal 5, and is finally discharged from the water outlet 3. The outer side of each ceramic membrane element 6 is connected to the water inlet 2, and one end of each ceramic membrane element 6 is sealed with the blind end positioning seal 4. The other end of each ceramic membrane element 6 passes through the water outlet positioning seal 5 and is connected to the water outlet 3, and each ceramic membrane element 6 is sealed with the water outlet positioning seal 5, so that the sewage has only one circulation channel, the ceramic membrane element 6. When in use, the sewage enters the housing 1 below the water outlet positioning seal 5 from the water inlet 2, and then enters its interior after being filtered by the ceramic membrane element 6, and finally flows to the top of the water outlet positioning seal 5, and is finally discharged from the water outlet 3, realizing the purification of the sewage.

[0038] The ceramic membrane water purifier of the present invention adopts a filter assembly composed of multiple ceramic membrane elements 6, which can effectively increase the filter area, process a large amount of water, improve the filtration accuracy, will not generate secondary wastewater, is easy to clean, and is not easy to be blocked by dirt. At the same time, it does not require frequent replacement of filter elements, does not require additional energy consumption, and has a longer service life. It is particularly suitable for deep purification treatment of drinking water in urban and rural households.
