Problems solved by technology

[0005] Existing flat membranes usually require frame support, the frame structure is relatively thick, and the packing density of the assembly is small, resulting in a large footprint, and a large amount of aeration is required for high energy consumption during operation
[0006] The filling density of the existing hollow fiber membrane is significantly higher than that of the flat membrane, but it is easy to be entangled by hair during operation, the roots are seriously accumulated, and broken wires are prone to occur, and offline cleaning is required after long-term operation, which consumes a lot of manpower and material resources

Abstract

The invention discloses a corrugated film. A support structure is arranged in the corrugated film. The corrugated film has the advantages that through the support structure in the corrugated film, compressive property of the corrugated film is improved greatly, and the applicable working pressure of the corrugated film is increased. The invention further provides a manufacture method of the corrugated film. The manufacture method includes preparing a composite film, performing hot extrusion on the prepared composite film to form corrugation, and performing press fit on the composite film and the support structure to acquire the corrugated film. A brand-new corrugated-film manufacture method is provided besides coating-based film formation methods, and can be applied to corrugated films which cannot be easily dissolved by solvents and cannot be processed by coating methods. The manufacture method has the advantages that the manufacture method is simpler than the prior art, chemical rawmaterial preparation steps, coating steps and coagulation bath are omitted, water is saved, environmental protection is achieved, and pollutants are avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a corrugated membrane and a manufacturing method thereof. Background technique [0002] Membrane Bioreactor Membrance Bioreactor, MBR is a biochemical reaction system that integrates membrane separation technology and biodegradation of bioreactors. [0003] Membrane separation technology is a commonly used physical treatment technology in the field of sewage treatment. [0004] There are two main structural forms of membranes usually selected for MBR: hollow fiber membranes and flat membranes. [0005] The existing flat membrane usually needs frame support, the frame structure is thick, and the packing density of the group device is low, which leads to a large floor area, and requires a large amount of aeration and high energy consumption during operation. [0006] The filling density of the existing hollow fiber membrane is significantly higher than that of the flat m...
