摘　　要：膜通量是超滤膜技术的关键设计参数,设计中选取合理的膜通量直接影响工程造价和系统稳定性,影响超滤膜通量的几个关键因素有水源特性、膜材质、膜系统类型、季节和水温、运行方式、预处理工艺等。本文统计了国内部分应用超滤膜技术的给水厂工艺、超滤膜系统类型、膜通量等情况,并分析了应用情况和膜通量取值合理性。在此基础上,详细介绍了某给水厂超滤膜技术设计的应用情况,旨在为类似超滤给水厂的设计提供参考。Membrane flux is a key design parameter for ultrafiltration membrane technology,and a reasonable membrane flux selection in design directly affects engineering cost and system stability.Several key factors affect the flux of ultrafiltration,including water source characteristics,membrane materials,types of membrane systems,seasons,water temperature,operation mode,and pretreatment,etc.This paper summarized the application of ultrafiltration membrame technology process,types of membrane systerm,and membrane flux in some domestic water supply plants,and analyzed their application situations and the rationality of the value of membrane flux.On this basis,a detailed introduction was given to the application of ultrafiltration membrane technology design in a certain water supply plant,aiming to provide reference for the design of similar ultrafiltration water supply plants.
