Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc. Various fields are increasingly entering the daily life of ordinary people, and ceramic membrane is an inorganic separation membrane with separation function made of ceramic material as a medium, which is essentially a porous membrane with high open porosity. Ceramics have various structural forms such as tube type and plate type. Therefore, the ceramic membrane is introduced into the sewage treatment system and a silicon carbide ceramic membrane water purification device is proposed.

There are some problems in today's silicon carbide ceramic membrane water purification devices. Most of the existing silicon carbide ceramic membrane water purification devices have smooth inner edges of the water body channels, so that the contact area between the water body and the membrane body is small, so that the water can be purified. The effect is poor, and at the same time, the sewage contains a large amount of large particulate matter, which is easy to cause damage to the inner edge of the water channel. In view of this, we propose a single-branch silicon carbide ceramic membrane water purification device.
