摘要
目的了解温岭市生活饮用水的水质状况,为生活饮用水的质量管理提供科学依据。方法2017年—2020年在温岭市内采集生活饮用水样品693份,按照《生活饮用水标准检验方法》(GB/T 5750—2006)检测水质31项指标,依据《生活饮用水卫生标准》(GB 5749—2006)进行评判。结果水样总合格率为92.64%;4年间合格率差异有统计学意义,用水质量逐渐提升;共13项检测指标检出不合格项;不同季度水质合格率之间与各类水质合格率之间均无明显差异;县市级、镇级水厂水的合格率间差异有统计学意义。结论温岭市生活饮用水的整体合格率虽较高,但仍有进一步完善空间,特别是农村镇级水厂的不合格指标,仍需加强针对性资源的投入,完善生活饮用水的生产及输送管理。
Objective To understand the quality of drinking water in Wenling City and provide scientific basis for the quality management of drinking water.Methods From 2017 to 2020,693 samples of drinking water were collected in Wenling City.According to GB/T 5750—2006 Standard Test Method for Drinking Water,31 indicators of water quality were detected and assessed according to GB 5749—2006 Hygienic Standard for Drinking Water.The total qualified rate of water sample was 92.64%.Analysis of the pass rate during the four years showed that the difference was statistically significant,and the water quality was gradually improved.There were a total of 13 unqualified items,but no significant difference between the qualified rate of water quality in different seasons and different water samples was observed.There was statistical significance on the difference on the qualified rate of water between county and town water plants.Conclusion Although the overall qualified rate of drinking water in Wenling City is high,there is still room for further improvement.Especially for the unqualified index of rural township water plants,it is still necessary to strengthen the investment of targeted resources and improve the production and transportation management of drinking water.
