目的了解获嘉县2013-2015年生活饮用水水质卫生监测及其发展变化趋势,探讨其生活饮用水卫生状况及其影响因素,保障居民用水安全。方法按照《生活饮用水标准》(GB/T5750-2006)进行水样采集与检测,按照《生活饮用水卫生标准》(GB5749-2006)对检测结果进行评价。结果 2013-2015年共检测水样167份,不同年份合格率比较,差异具有统计学意义(χ~2=79.887,P<0.05),影响2013-2015年水样不合格的指标主要有浑浊度、菌落总数等检测指标;其中2014、2015年菌落总数合格率最低,2013-2015年比较差异具有统计学意义;而色度、氟化物指标三年合格率比较,差异无统计学意义。结论获嘉县生活饮用水的卫生状况仍不容乐观,菌落总数是影响近两年获嘉县饮用水的主要卫生问题,应加强对生活饮用水的管理,提高水质合格率,确保民众用水安全。
Objective To understand the hygienic monitoring of drinking water quality in Xinjia County from 2013 to 2015 and the trend of its development and changes, discuss the hygienic condition of drinking water and its influencing factors in order to ensure the safety of residents’ water use. Methods According to “drinking water standard” (GB / T5750-2006) for water sampling and testing, according to “drinking water health standards” (GB5749-2006) on the test results were evaluated. Results A total of 167 water samples were tested during 2013-2015. The passing rates in different years were statistically different (χ ~ 2 = 79.887, P <0.05). The indicators that affected the unqualified water samples in 2013-2015 were mainly turbidity , The total number of colonies and other indicators of detection; of which the total number of colony in 2014,2015 the lowest pass rate, 2013-2015 was statistically significant difference; and chroma, fluoride indicators three-year pass rate, the difference was not statistically significant. Conclusion The sanitary status of drinking water in Xijia County is still not optimistic. The total number of colonies is the major health problem that affects the drinking water in Xijia County in the past two years. Management of drinking water should be strengthened to improve the qualified rate of water quality and ensure the safety of public drinking water.
