Therefore, sewage treatment equipment is needed to filter it to form reclaimed water before it can be discharged or utilized normally. Reverse osmosis membrane is a commonly used filtration component in sewage treatment equipment and is the core component of reverse osmosis technology. The principle is that under the action of a pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semipermeable membrane, so these substances and water are separated. This can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water.

[0003] The existing reverse osmosis membrane is mainly composed of a long tube with a through hole, a reverse osmosis membrane body, an outer shell and a sealing cover. In order to improve the filtering effect, a plurality of reverse osmosis membrane bodies (after winding) are usually placed in the outer shell. The sealing cover can be used to squeeze the reverse osmosis membrane body, so that the fixed installation of multiple reverse osmosis membrane bodies can be achieved. However, when one or more reverse osmosis membrane bodies are missing, the sealing cover cannot be squeezed on the reverse osmosis membrane body, and the reverse osmosis membrane body is easy to shake in the outer shell, affecting the normal filtration of wastewater.
