摘　　要：强调了研究内压中空超滤膜丝纯水通量分布特性对于研究超滤工艺的意义,给出了单端给水方式与双端给水方式内压膜丝沿程通量的变化规律,分析了单端与双端给水内压膜丝沿程通量的压力特性及温度特性,比较了长膜丝与短膜丝沿程通量特性的差异,明确了内压中空超滤膜丝双端给水方式所具有的多项技术优势,为中空超滤膜组件及膜系统的运行分析提供参考。The significance of studying the pure water flux distribution characteristics of the internal pressure-type ultra-filtration membrane fiber to the study of ultra-filtration technology is emphasized. The change law of the internal pressure membrane fiber along-path pure water flux in forms of single-ended water supply and double-ended water supply is given,and the pressure and temperature characteristics of them analyzed. The differences of the characterstics of long membrane fiber and short membrane fiber along-path flux are compared. Various technical advantages of the internal pressure type hollow ultra-filtration membrane fiber in form of double-ended water supply are made clear. A reference has been provided for the running analysis on hollow ultra-filtration membrane modules and membrane systems.
