【摘要】 [目的]对上海市生活饮用水管网水质进行监测分析,推进饮用水卫生监督信息化,保障城市饮用水卫生安全。[方法]应用上海市生活饮用水卫生监督预警控制平台,收集2009年5月至2012年12月上海市生活饮用水管网水监测数据并进行统计分析。[结果]2009年5月至2012年12月,平台共连续收集117个管网的水质监测数据5095条,水质合格率为82.7%,各年度合格率分别为72.1%、83.3%、85.5%和85.9%,差异有统计学意义(χ2=87.038,P<0.01)。按照供水水源、供水单位级别等划分的7个不同地区的管网水质差异有统计学意义(χ2=638.014,P<0.01)。共有1087项次指标超标。不同地区的管网水水样中,除总大肠菌群和色度外,消毒剂余量、菌落总数、浑浊度、铁、锰和耗氧量合格率差异均有统计学意义。[结论]上海市生活饮用水管网水水质总体情况良好,信息化建设有利于保障城市饮用水的安全。更多还原

【Abstract】 [Objective]To monitor the drinking water quality and promote informatization of drinking water health inspection,so as to safeguard drinking water quality in Shanghai.[Methods]Data of drinking water quality monitoring the municipal supply networks were collected and statistically analyzed by the Shanghai Drinking Water Health Inspection and Warning Control Platform.[Results]From May 2009 to Dec 2012,5095 entries of drinking water quality data in 117 municipal supply networks were collected.The total qualified rate was 82.7%.The qualified rates were 72.1%,83.3%,85.5% and 85.9% for each selected year respectively with significant difference(χ2=87.038,P<0.01).According to different water sources and grades of water supply plants,the whole city was divided into seven districts,and the difference in drinking water quality among the seven districts was significant(χ2=638.014,P<0.01).A total of 1087 indices were not qualified.The differences in the qualified rates of disinfectant residual,total bacterial count,turbidity,iron,manganese,and chemical oxygen demand among 7 districts were significant,except total coliform group and color.[Conclusion]Drinking water quality in distribution networks in Shanghai is good in general,and informatization construction will safeguard urban drinking water quality.更多还原
