[0002] Membrane bioreactors (MBRs) are a new wastewater treatment technology that combines membrane technology with biological treatment processes. The membrane's efficient retention allows microorganisms with long generation times to be continuously retained within the reactor, achieving advanced wastewater treatment. In recent years, this technology has been widely used in wastewater reuse, with the resulting reclaimed water typically used for green space irrigation and landscape water replenishment.

[0003] The internal structure design of the existing membrane bioreactor is unreasonable. When used for a long time, a lot of impurities will accumulate inside the membrane, and it needs to be replaced. The tiny particles in the sewage, such as colloids or solute macromolecules, will undergo mechanical action or physical and chemical reaction with the membrane, causing them to be adsorbed and deposited on the membrane surface or in its pores, causing the membrane pore size to become smaller and even blocked, and ultimately causing irreversible changes in membrane separation and permeation flow characteristics, which accelerates the rate of membrane fouling.
