A HOLLOW FIBER MEMBRANE MODULE, A MEMBRANE BIOLOGICAL REACTOR AND A WATER-PROCESSING EQUIPMENT USE OF IT

摘要

A hollow fiber membrane module includes a hollow fiber membrane bundle (5) consisted of a plurality of hollow fiber membrane filaments (3), end part(s) (6, 1) at one end or both ends of the hollow fiber membrane bundle (5), an air inlet pipe (9) and a produced water pipe (8). An air distributing device (11) having air distributing holes (13) is disposed at an end surface of at least one of the end parts. The air distributing device (11) is communicated with the air inlet pipe (9). The air distributing holes (13) are opened towards roots of the hollow fiber membrane filaments (3). The phrase "end part(s) at one end or both ends of the hollow fiber membrane bundle (5)" means that one end of the hollow fiber membrane bundle (5) has the end part or both ends of the hollow fiber membrane bundle (5) have the end parts.
