This invention relates to the field of wastewater treatment technology, and in particular to a wastewater purification and reuse device based on a membrane bioreactor. Addressing the limited removal efficiency of pollutants adhering to membrane elements in existing technologies, this invention provides a wastewater purification and reuse device based on a membrane bioreactor. The device includes a treatment tank containing a membrane bioreactor assembly. The assembly includes an assembly frame with multiple membrane elements mounted on it. Scrapers that cooperate with the membrane elements are located on both sides of a horizontal plate. A cleaning assembly also includes a vertically movable frame. When the frame moves downwards, the horizontal plate moves downwards, and the scrapers clean the outer surface of the membrane elements downwards. A movable scraper is located on a support, and a collection box is located on one side of the support. When the scraper moves to one side, the collection box opens. By directly scraping away impurities adhering to the outer surface of the membrane elements, suspended solids, colloidal particles, microbial flocs, and other pollutants on the membrane surface can be removed quickly and effectively.
