摘要:
末梢水与其水源水的数据“倒挂”现象是影响居民饮水健康的安全隐患。基于末梢水数据“倒挂”现象在新闻报道、政府信息公开及相关调查研究中的表现形式,分析了引起末梢水数据“倒挂”的原因主要包括:监测采样、分析偏差,物理因素和化学、生物反应以及综合因素造成的污染等。提出,在饮用水水源方面,加强规范化管理,保持水源水水质合格并长期稳定;在水处理阶段,选择适宜且安全高效的水处理方式;在水管输送阶段,选择健康的管道材质并合理规划设计、维护输水管网体系;在饮用水使用阶段,加强用水宣传,让居民养成良好的健康用水习惯。从而逐渐消除末梢水数据“倒挂”现象,保障居民的饮水安全。

Abstract:
The phenomenon of the data inversion between the tap water and its source water is a hidden danger that affects the drinking water safety of residents. Based on the description of the data inversion phenomenon in news reports, government information disclosure and related investigation and research, the causes of the data inversion were analyzed, which mainly include the deviations come from the sampling and analysis of the monitoring, and pollution caused by physical factors, chemical and biological reactions and the comprehensive factors. In terms of source water, we should strengthen standardized management to keep the water quality qualified and stable for a long time. In the stage of water treatment, appropriate, safe and efficient water treatment methods should be selected. In the stage of drinking water transportation, harmless pipe material, reasonable design and maintenance of the water pipe network system are necessary; In the drinking water use stage, the publicity of water usage should be strengthened, so as to help the residents develop a good habit. Thus, the phenomenon of the data inversion will be gradually eliminated to ensure the safety of drinking water for residents.
Key words:  Tap water  Source water  Data inversion  Drinking water safety
