| titleOfInvention | Preparation method of multilayer reverse osmosis composite membrane |
| abstract | The invention belongs to the technical field of water treatment, and particularly relates to a preparation method of a multilayer reverse osmosis composite membrane, which comprises a shell, a water inlet pipe and a water outlet pipe; the shell is designed in an I shape; a pressurizing cavity is formed in the shell; one end of the shell is provided with a first groove; a second groove is formed in one end, far away from the first groove, of the shell; the first groove and the second groove are both in T-shaped design; the side walls of the first groove and the second groove are both in threaded design; the water inlet pipe is connected with the shell through the first groove; the invention makes the pressurizing plate rotate by using the impact effect of water flow to apply pressure to the water flow, thereby accelerating the water flow permeation efficiency, and simultaneously, the rotation of the rotating shaft makes the ultraviolet rays scattered by the ultraviolet lamp uniformly diffuse outwards, thereby effectively improving the purification effect of the photocatalyst material in the permeation bag on the permeation bag, and simultaneously, by arranging the protective layer, the separation layer is prevented from being directly impacted by the water flow, and the durability of the purification performance is effectively enhanced. |
