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
[0007] Chinese patent CN204342505U discloses a MBR membrane assembly, which can effectively remove solid pollutants represented by hair fibers. The membrane assembly disclosed in this patent is also one of the current conventional membrane assembly structures. This structure has air washing efficiency Relatively low, easy to hide mud in the middle of the diaphragm, and unstable operation

Abstract

The invention belongs to the technical field of a filtering membrane, and particularly relates to a laminar flow type hollow fiber filtering membrane group device. The laminar flow type hollow fiber filtering membrane group device comprises a laminar flow type hollow fiber filtering diaphragm, a membrane group device support frame and an aeration pipe, wherein the laminar flow type hollow fiber filtering diaphragm is fixed in the membrane group device support frame; the aeration pipe is positioned at the bottom of the membrane group device support frame. The laminar flow type hollow fiber filtering membrane group device has the advantages that the gas washing efficiency is higher; the operation is more stable.

Description

technical field [0001] The invention belongs to the technical field of filter membranes, and in particular relates to a laminar flow hollow fiber membrane module. 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 mem...
