超滤膜的分类
Classification of ultrafiltration membranes
超滤膜按结构型式分为板框式（板式）、中空纤维式、纳米膜表超滤膜、管式、卷式等多种结构。其中，中空纤维超滤膜是超滤技术中最为成熟与先进的一种形式。中空纤维外径0.4-2.0mm，内径0.3-1.4mm，中空纤维管壁上布满微孔，孔径以能截留物质的分子量表达，截留分子量可达几千至几十万。原水在中空纤维外侧或内腔加压流动，分别构成外压式与内压式中空超滤膜。超滤是动态过滤过程，被截留物质可随浓缩液排除不致堵塞膜表面，可长期连续运行。
Ultrafiltration membranes can be divided into plate-frame type (plate type), hollow fiber type, nanometer membrane surface ultrafiltration membrane, tube type, roll type and other structures. Among them, hollow fiber ultrafiltration membrane is the most mature and advanced form of ultrafiltration technology. The outer diameter of hollow fiber is 0.4-2.0 mm and the inner diameter is 0.3-1.4 mm. The wall of hollow fiber is covered with micropores. The pore size is expressed by the molecular weight of the material that can be intercepted. The intercepted molecular weight can reach tens of thousands to hundreds of thousands. Raw water flows under pressure outside the hollow fiber or inside the cavity to form a hollow ultrafiltration membrane with external pressure and an internal pressure respectively. Ultrafiltration is a dynamic filtration process, the intercepted substances can be removed with the concentrated solution without blocking the membrane surface, and can run continuously for a long time.
