汶川地震灾区城市供水的水质风险和应急处理技术与工艺

Water quality risk and emergent treatment of municipal water supply after the Wenchuan Earthquake

对汶川大地震后震区饮用水水源存在的次生污染风险进行分析,其中微生物浓度升高是首要风险,同时还存在大量使用消杀剂引起的杀虫剂污染和水源臭味增强的风险。针对这些风险,开展了一系列应急处理技术的验证性试验,提出了保障性应急处理工艺、强化吸附应急处理工艺和强化氧化应急处理工艺三种方案,以应对可能出现的震后次生水源污染,确保城市饮用水水质安全。

Secondary pollution risks in water source for municipal water supply in the earthquake regions after the Wenchuan Earthquake were analyzed. Predominated risk was microorganism increasing in source water. Pesticides, which were used in great amount in disposal of earthquake remains, and test and odor were other risks. Some verification tests of emergent water supply treatment were made and three processes for waterworks were suggested against possible water source pollution after earthquake, including the protective process, enhanced process by adsorption and enhanced process by oxidation.
