Problems solved by technology

[0006] According to the records of products sold on the market and related literature, the existing hollow fiber filter membranes have low aeration efficiency for scrubbing the membrane filaments, the overall strength of the membrane shell is low, and the joints of the membrane shell are prone to water leakage. And it is difficult to detect the leak point and other problems

Abstract

The invention belongs to the technical field of filtration membranes, in particular to a laminar flow hollow fiber filtration membrane. The laminar flow hollow fiber filtration membrane includes a membrane shell, glue and membrane filaments, the membrane shell includes a membrane filament packaging tank, a water collecting pipe and a water outlet, the membrane filaments are packaged in the membrane filament packaging tank by the packaging glue, and the membrane filaments The encapsulation tank is bonded together with the water collecting pipe through the adhesive glue of the membrane shell, the water collecting pipe is connected with the water production port, and an air guide port is arranged in the middle of the water collecting pipe. Compared with the prior art, the laminar flow hollow fiber filter membrane of the present invention has high structural strength, good aeration and scrubbing effect, high design flux, and is more resistant to pollution.

Description

technical field [0001] The invention belongs to the technical field of filter membranes, in particular to a laminar flow hollow fiber filter membrane. 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 mainly includes the following types. For example, Mitsubishi Rayon Co., Ltd. of Japan discloses a hollow fiber membrane in CN105536544. The hollow fiber membrane is composed of a membrane shell for water collection up and down and a membrane wire in the middle, and is characterized in that it is not limited by the purpose of use, Furthermore, the compressive strength of the hollow fiber membrane can be...
