Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of sewage filtration and separation, and more particularly relates to a sewage filtration device based on a hollow fiber ultrafiltration membrane filter core. BACKGROUND

[0002] The hollow fiber ultrafiltration membrane filter core is a kind of filter material taking hollow fiber ultrafiltration membrane as the core, which can intercept suspended solids, colloids, macromolecular organic matter, microorganisms and other pollutants in sewage under certain pressure by using the pore size screening effect of the membrane, so as to realize the purification and separation of sewage. At present, the sewage purified by the hollow fiber ultrafiltration membrane filter core contains large particles of suspended impurities. Since the traditional hollow fiber ultrafiltration membrane filter core purification equipment does not have the interception capacity of large particles of suspended impurities, the suspended impurities are easy to be stuck in the membrane pores to form blockage, resulting in a sharp drop in the filtration flux of the filter core, so that the filter core needs to be cleaned or replaced frequently, thereby increasing the operation cost of the sewage purification equipment.
