    摘要： A hollow-fiber filtering module includes a casing having an open end and an inlet for introducing water to be treated thereinto. A bundle of hollow fibers is mounted within the casing, each of the hollow fibers having an open end. A fastening member sealingly joins the open ends of the hollow fibers to the open end of the casing in sealing relation thereto, the open ends of the hollow fibers opening to the exterior of the casing. Part of the hollow fibers are made of a microporous membrane having a portion of a hydrophobic nature, and the other hollow fibers are hydrophilic microporous membranes. Gas introduced into the filtering module can easily permeate the hydrophobic portions of the hollow fibers and is discharged through the bores of the hollow fibers from their open ends together with the filtered water. There is also disclosed a water purification device employing such a hollow-fiber filtering module.

    摘要翻译： 中空纤维过滤模块包括具有开口端的壳体和用于引入待处理水的入口。 一束中空纤维安装在壳体内，每个中空纤维都具有开口端。 紧固构件将中空纤维的开口端密封地连接到壳体的开口端，与其密封关系，中空纤维的开口端通向壳体的外部。 中空纤维的一部分由具有疏水性部分的微孔膜制成，其它中空纤维是亲水性微孔膜。 引入过滤模块的气体可以容易地渗透中空纤维的疏水部分，并通过中空纤维的孔从其开口端与过滤的水一起排出。 还公开了一种采用这种中空纤维过滤模块的水净化装置。
