[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Sewage needs to go through layers of processes during treatment. The most commonly used sewage treatment methods are generally physical treatment, chemical treatment, and biological treatment, so that sewage treatment can meet discharge standards. In the sewage treatment process, hollow fiber ceramic membrane components can filter and treat tiny particles inside the sewage through reverse osmosis, so that the sewage can be treated in depth. Therefore, a sewage treatment equipment with a hollow fiber ceramic membrane component is needed;

A water outlet is provided at the top of the membrane shell, a water inlet is provided at the bottom, and a water outlet is provided on the top side. The ceramic membrane assembly is cylindrical and has a gap with the membrane shell. The ceramic membrane assembly includes two arc-shaped core bodies bonded to each other, and the arc-shaped core bodies include a first core body, a second core body... and an Nth core body arranged parallel to each other, N is an integer not less than 1, one side of the first core body is an arc-shaped surface, and the other side is a plane, and the left and right sides of the remaining core bodies are both planes, and the upper and lower sides are both arc-shaped surfaces. The first core body, the second core body... and the Nth core body are bonded in sequence near the end to form an arc-shaped core body, and there is a gap between any two adjacent core bodies, and the gap near the bonding point is filled with a sealing body, and a sealing body is filled between the side of the ceramic membrane assembly near the top and the membrane shell.

The spiral grooves 4501 are distributed in a strip-shaped spiral shape on the inner wall of the filter cartridge 41. The strip width of the spiral grooves 4501 is equal to the distance from the arc surface of the arc core 4701 to the inner wall of the filter cartridge 41, and the end of the spiral groove 4501 extends to the inner wall of the volute water outlet cover 4502.

[0039] It can be understood that the water outlet chamber 4603 and the strip drainage groove 4604 can discharge the clean water seeping out of the arc core 4701 into the spiral groove 4501 between the filter cartridge 41 and the arc core 4701, and the clean water can flow downward in a spiral manner in the spiral groove 4501. Since the shape of the spiral groove 4501 will increase the circulation speed of the clean water, the water outlet speed of the water outlet chamber 4603 and the strip drainage groove 4604 will also increase when the clean water circulates quickly. When the clean water flows into the end of the spiral groove 4501, it will enter the interior of the volute water outlet cover 4502. The clean water entering the volute water outlet cover 4502 can be discharged through the annular clean water outlet 44 quickly.

When the arc core 4701 is inserted between the partition 4601, the edge of the arc core 4701 will be inserted into the partition 4601 and the protective strip 4 605, the protection strip 4605 can effectively protect the most vulnerable position of the arc core 4701. When the arc core 4701 filters sewage, clean water will penetrate outward. When the clean water penetrates into the water outlet chamber 4603, the water outlet chamber 4603 can transport the clean water to between the arc core 4701 and the filter cartridge 41 through the strip drainage groove 4604.
