摘　　要：针对饮用水源污染和水质安全风险及藻类、臭味、氨氮、砷等有毒有害物质去除的技术难题,“十一五”“十二五”期间,“水专项”研发了水源调控、水质净化、管网输配和水质监测、预警应急、安全管理等关键技术,构建了以臭氧-活性炭、膜分离等为核心的饮用水安全保障多级屏障工艺,实现了关键装备与材料的国产化,形成了“从源头到龙头”全流程饮用水安全保障技术体系,并在太湖流域、南水北调受水区进行了规模化示范应用,累计示范与推广应用的供水规模超过1 000万m^3 d,直接受益人口达8 000万人以上,技术支撑全国城市供水水质达标率由2009年的58.2%提高到目前的96.0%以上,也为全国城乡供水规划、城镇供水水质督察和供水应急救援基地建设等提供了体系性的技术支撑。In response to problems of water source contamination, water quality security risk, and the difficult removal of poisonous and pernicious substances such as algae, odor, ammonia nitrogen and arsenic, the National Major Science and Technology Program for Water Pollution Control and Treatment in the 11 th and 12 th five-year plan periods developed significant technologies covering water regulation, water quality purification, water distribution system and its monitoring and evaluation, advance warning and emergency treatment, and drinking water security control. On this basis, the drinking water insurance multi-barrier process with ozone-GAC and membrane separation as core technologies has been established, and domestic-produced critical equipment and materials realized. Moreover, the drinking water insurance technology system from water source to tap has been established and applied in Taihu Lake Basin and South-to-North Water Diversion Project benefited regions in large scales, leading to an accumulative water supply scale of over 10 million m^3 d and a benefited population of over 80 million, and providing technical support for improvement of the qualified rate of urban water supply quality from 58.2% in 2009 to 96.0% presently. In the meanwhile, the achievements have provided systematic technical support for national urban-rural water supply planning, urban water supply quality supervision and the construction of water supply emergency rescue bases.
