<p>A hollow fiber membrane module combined with air diffusers comprises: a) a hollow fiber membrane (15); b) a lower structure including an air or oxygen inlet (7-a), air diffusers (1-a, 1-b) each formed with air or oxygen discharge holes (2) and hitched in a U-shape with hollow fiber membrane (15) in a U-shape, lower connectors (4-a, 4-b) each connecting a strut and the air diffusers, and legs (6); c) an upper hollow fiber membrane distribution structure (9) for dispersedly arranging distal ends of bundles of the hollow fiber membranes; d) a head (12) for sealing the upper hollow fiber to membrane distribution structure (9) and the hollow fiber membrane (15), and equipped with a filtered water outlet (13); and e) struts (8-a, 8-b) for connecting the upper hollow fiber membrane distribution structure (9) and the lower structure. The hollow fiber membrane combined with air diffusers is provided such that, when installed in a biological treating reactor, air or oxygen bubbles generated from air or oxygen discharge holes at the air diffusers of the hollow fiber membrane module directly clean the hollow fiber membrane (15) to prevent occurrence of impurities, thereby enabling to maintain a good permeation efficiency for a long period of time.</p> |
