世博会直饮水水质推荐标准及配套工艺试验研究

技术总结世博会直饮水水质推荐标准及配套工艺试验研究李伟英1,�郭金涛2,�许京晶2,�陆�辉2,�张�东3(1.同济大学长江水环境教育部重点实验室,上海200092;2.同济大学污染控制与资源化研究国家重点实验室,上海200092;3.上海市自来水市北有限公司,上海200086)��摘�要:�结合国际权威性的饮用水水质标准和我国现行的�生活饮用水卫生标准�(GB5749�2006),提出了上海世博会直饮水水质推荐标准,为确保2010年上海世博会的饮用水安全及进一步完善我国饮用水水质标准提供参考。同时针对世博会直饮水水质要求,采用颗粒活性炭/超滤/紫外消毒组合工艺对模拟的世博园区自来水进行深度处理。结果表明,该工艺出水的浊度、CODMn、UV254和细菌总数分别为0.155NTU、0.35mg/L、0.009cm-1和零,出水水质达到了GB5749�2006和�饮用净水水质标准�(CJ94�2005)的要求,同时也满足世博会直饮水水质推荐标准的要求。由此可知,采用颗粒活性炭/超滤/紫外消毒深度处理工艺制备直饮水是可行的。��关键词:�上海世博会;�直饮水;�超滤;�颗粒活性炭;�紫外消毒中图分类号:TU991��文献标识码:C��文章编号:1000-4602(2010)19-0045-05��基金项目:苏州市重点科技支撑项目(ZS0801);�上海市科委世博科技专项(07DZ05804);�国家水体污染控制与治理科技重大专项(2008ZX07421-006)InvestigationonRecommendedStandardsandSupportProcessforExpoDirectDrinkingWaterQualityLIWe-iying1,�GUOJin-tao2,�XUJing-jing2,�LUHui2,�ZHANGDong3(1.KeyLaboratoryofYangtzeRiverWaterEnvironment,TongjiUniversity,Shanghai200092,China;2.StateKeyLaboratoryofPollutionControlandResourcesReuse,TongjiUniversity,Shanghai200092,China;3.ShanghaiWaterworksShibeiCo.Ltd.,Shanghai200086,China)��Abstract:�BasedonboththeworldwideauthoritativedrinkingwaterqualitystandardsandtheStandardsforDrinkingWaterQuality(GB5749-2006),therecommendedstandardfordirectdrinkingwaterqualityof2010ShanghaiWorldExpowasproposedtoensurethesecurityoftheExpodrinkingwaterandprovideareferencefortheimprovementofdrinkingwaterqualitystandardinChina.AccordingtotherequirementofExpodirectdrinkingwaterquality,thecombinedprocessofgranularactivatedcarbon,u-ltrafiltrationandUVdisinfectionwasusedtotreatthesimulateddrinkingwaterforShanghaiWorldExpoPark.Theresultsshowthattheeffluentturbidity,CODMn,UV254andtotalbacterialcountare0.155NTU,0.35mg/L,0.009cm-1and0cfu/mLrespectively,whichmeetsGB5749-2006,theWaterQualityStandardforFineDrinkingWater(CJ94-2005)andtherecommendedstandardfordirectdrink-ingwaterqualityof2010ShanghaiWorldExpo.Itisconcludedthatitisfeasibletousethecombinedprocessofgranularactivatedcarbon,ultrafiltrationandUVdisinfectiontoproducedirectdrinkingwater.�45�第26卷�第19期201
