Abstract

The invention belongs to the technical field of filter membranes, and particularly relates to a column type hollow fiber filter membrane. The column type hollow fiber filter membrane is characterizedby comprising a membrane shell, packaging glue and membrane filaments, wherein the membrane shell comprises a water production port, a water collection pipe, a membrane filament parting strip and a membrane filament packaging groove. Compared with the prior art, the column type hollow fiber filter membrane has the advantages that the production efficiency is high, a packaging mode is simple, a membrane product forms an integral structure in the packaging process, strength is high, and the membrane filaments are uniformly distributed.

Description

technical field [0001] The invention belongs to the technical field of filter membranes, and in particular relates to an arrayed hollow fiber filter membrane and a preparation method thereof. Background technique [0002] From 2010 to 2018, the average annual growth rate of my country's membrane production value exceeded 20%. Membrane bioreactor sewage treatment technology is an advanced sewage treatment technology that is currently being promoted in my country. The hollow fiber filter membrane is the core component of the membrane bioreactor system. [0003] The structural form of the hollow fiber filter membrane module mainly includes the following types. For example, Japan's Mitsubishi Rayon Co., Ltd. discloses a hollow fiber membrane module in CN105536544. The hollow fiber membrane module is composed of a membrane shell for upper and lower water collection and a membrane wire in the middle, and is characterized by not being limited by the use, Furthermore, the compres...
