Abstract

The invention relates to a membrane filtration system, which enables the separation membrane to reciprocate, thereby effectively removing foreign matter attached to the separation membrane while saving energy usage. The invention provides a membrane filtration system, and the membrane filtration system includes: a treatment tank; a membrane support The frame is configured in the above-mentioned treatment tank; the separation membrane module is installed on the above-mentioned membrane support frame; the reciprocating device is connected with the above-mentioned membrane support frame to make the above-mentioned membrane support frame reciprocate; The lower end floats the sludge accumulated in the treatment tank; and the control part adjusts and controls the reciprocating distance or the number of vibrations of the separation membrane module.

Description

technical field [0001] The present invention relates to a membrane filtration system, and more specifically, to a membrane filtration system capable of efficiently removing foreign matter adhering to a separation membrane while saving energy usage by reciprocating the separation membrane. Background technique [0002] Generally speaking, separation membrane technology is one of the separation technologies that utilize the material selective permeation properties of polymer materials. Unlike distillation technology, the membrane separation process has no phase change, so energy can be saved, and the process is simple. Therefore, the device It takes up little space. Separation membranes are developed around reverse osmosis membranes, and ultrafiltration membranes (ultrafiltration), microfiltration membranes (microfiltration), and nanofiltration membranes (nanofiltration) are widely used. [0003] Membrane bioreactors (MBR, Membrane Bio Reactors), one of membrane filtration sy...
