Abstract

The invention discloses a corrugation membrane, a spiral membrane component thereof and a filtering method, and belongs to the technical field of tap water deep purification or sewage disposal. A non-woven fabric supporting layer of the corrugation membrane is connected with the face of the corrugation membrane. A corrugation radius is arranged on the side face of the corrugation membrane. The lower portion of the corrugation membrane is connected with a water through channel fabric. The lower portion of the water through channel fabric is connected with a flat sheet membrane. Wave troughs of corrugations at the upper portion of the corrugation membrane are water inlet channels. Corrugation holes formed by the water through channel fabric, the flat sheet membrane structure and the corrugation membrane are water through channels. The water through channel fabric is connected with a glue line position. The glue line position wraps the membrane and then is connected with a water through central collecting pipe, the glue sealing position wraps the water through central collecting pipe, and the water through channel fabric, the flat sheet membrane, the water inlet channels and the corrugation membrane wrap the glue sealing position. By adopting the corrugation membrane, the surface of the membrane is machined into corrugations, the area of the corrugation membrane is 1.2-1.5 times that of an ordinary flat sheet membrane, and the filling area of a device can be increased at least by 15-20% under the same space.

Description

technical field [0001] The invention relates to a corrugated membrane, a roll-type membrane element and a filtering method thereof, and belongs to the technical field of deep purification of tap water or sewage treatment. Background technique [0002] Flat membrane: a membrane that is flat or paper-shaped. Note: Flat sheet membranes usually have a support layer (such as non-woven fabric) and are used to prepare plate-and-frame, pleated, and spiral-wound membrane elements. [0003] Corrugated membrane: The flat membrane is made into a corrugated shape, but retains the original retention capacity. [0004] Microfiltration membrane: a separation membrane with an average pore size ≥ 0.01 μm. [0005] Ultrafiltration membrane: It consists of a very thin skin layer for separation and a thicker sponge-like or finger-like pore layer for support, and cuts membranes with a molecular weight of several hundred to several million. NOTE: The thickness of the epidermal layer is usually ...
