在查阅了大量的国内外文献资料基础上 ,主要介绍了超滤技术及预处理应用于饮用水净化的研究。尽管超滤是一种去除病原微生物 (病原菌、病毒和病原原生动物 )有效的消毒工艺 ,但因它的截留分子量比较高 ,去除天然有机物相对无效。试验证明 ,适当的预处理可使超滤膜不仅能去除天然水中大量颗粒状物质 ,同时也可去除溶解性有机物及THMFP On the basis of consulting a large amount of domestic and foreign documents and materials, this paper mainly introduces the application of ultrafiltration technology and pretreatment in drinking water purification. Although ultrafiltration is an effective disinfection process for the removal of pathogenic microorganisms (pathogens, viruses and pathogenic protozoa), it is relatively ineffective to remove native organics due to its high molecular weight cut-off. Experiments show that proper pretreatment can make ultrafiltration membrane not only can remove a large number of particulate matter in natural water, but also remove dissolved organic matter and THMFP
