//胡红梅1, 董秉直1, 宋亚丽1, 杨瑜芳2, 常 春2(1.同济大学环境科学与工程学院,上海200092;2.东丽纤维研究所中国有限公司,上海200241) : 采用高锰酸钾预氧化—混凝—微滤工艺对黄浦江微污染源水进行处理,考察了处理效果。结果表明,该工艺的出水浊度0.1NTU,对铁的去除率97%,对CODMn、UV254、TOC均有较好的去除效果,出水水质可达到《生活饮用水水质卫生规范》的要求。MnO2及其中间产物被膜截留是造成膜污染的主要因素,采用草酸和次氯酸钠进行膜清洗可使膜通量完全恢复。 : 微污染源水; 高锰酸钾; 预氧化; 混凝; 微滤:TU991 :C :1000-4602(2007)05-0097-04ApplicationofCombinedProcessofPotassiumPermanganatePreoxi-dation,CoagulationandMicrofiltrationforTreatmentofSourceWaterfromHuangpuRiverHUHong-mei1, DONGBing-zhi1, SONGYa-li1, YANGYu-fang2, CHANGChun2(1.SchoolofEnvironmentalScienceandEngineering,TongjiUniversity,Shanghai200092,China;2.TorayFibersTextilesResearchLaboratoriesChinaCo.Ltd.,Shanghai200241,China) Abstract: Thecombinedprocessofpotassiumpermanganatepreoxidation,coagulationandmicro-filtrationwasusedfortreatmentofmicropollutedsourcewaterfromHuangpuRiver,andthetreatmenteffectwasinvestigated.TheresultsdemonstratethatthiscombinedprocesscaneffectivelyremoveCODMn,UV254andTOCrespectively,witheffluentturbidityoflessthan0.1NTUandironremovaleffi-ciencyofmorethan97%.ThetreatedwaterqualitycanmeettherequirementsofSanitaryStandardforDrinkingWaterQuality.ThemembraneinterceptionofMnO2anditsintermediateisthemainreasoncau-singthemembranefouling.Oxalicacidandhypochloritesodiumcleaningcanrestorethemembranefluxentirely.
