Abstract

The invention belongs to the technical field of flat sheet membrane washing, and specifically relates to a flat sheet membrane online washing device and a washing method thereof. The flat sheet membrane online washing device comprises a feeding tube and a dosing tube which are connected, wherein an atomizing spray head is arranged at the outlet of the feeding tube; the exterior of the dosing tubeis sleeved with a washing sleeve through a bearing; a pore passage is arranged on the dosing tube; a hole is formed in the washing sleeve; and the pore opening direction is the same with the tangential direction of the tube wall of the washing sleeve. The flat sheet membrane online washing device disclosed by the invention is good in washing effect, convenient to use and low in operating cost, andhas wide market prospects.

Description

technical field [0001] The invention belongs to the technical field of flat film cleaning, and particularly relates to an on-line flat film cleaning device and a cleaning method thereof. Background technique [0002] Membrane bioreactor (MBR) is a kind of advanced sewage treatment technology that has gradually emerged in recent years. Because of its short process flow, good treatment effect, small footprint and high microbial concentration, it is developing rapidly in practical engineering. stage. Of course, while MBR has many advantages, it also has certain disadvantages: ① the membrane fouling is relatively fast; ② the investment cost is high. In particular, the problem of membrane fouling has become an urgent problem that limits its rapid popularization. [0003] Membrane fouling refers to the adsorption and deposition of particles, colloidal particles or solute macromolecules in the water and the membrane during the filtration process, which are caused by physicochemic...
