摘要
目的 了解2020—2022年凉山州喜德县生活饮用水水质卫生现状,为喜德县科学合理的饮用水水质监测和饮用水管理提供依据。方法 收集2020—2022年喜德县城区和13个乡镇326份水样,按照《生活饮用水水质检测标准检验方法》(GB/T 5750-2006)开展水质常规指标监测,依据《生活饮用水卫生标准》(GB 5749-2006)进行评价。采用卡方检验比较组间率的差异,以P<0.05为差异有统计学意义。结果 2020—2022年喜德县326份水样中合格水样为48份,总合格率为14.72%;喜德县供水单位以小型供水站为主;总大肠菌群合格率低(14.72%);丰水期水质合格率低于枯水期(χ^(2)=6.254,P=0.012)。结论 喜德县生活饮用水合格率低,主要原因为微生物超标。应加强饮用水消毒管理,完善管理机制,确保群众身体健康。
Objective To understand the status quo of drinking water quality and sanitation in Xide County of Liangshan Prefecture from 2020 to 2022,and to provide a basis for developing scientific and reasonable monitoring and management of drinking water quality in Xide County.Methods From 2020 to 2022,about 326 water samples were collected from urban areas of Xide County and 13 townships,and the routine indexes of water quality were monitored according to“Standard Test Method for Drinking Water Quality”GB/T 5750-2006,and the evaluation was carried out according to“Sanitary Standard for Drinking Water”GB 5749-2006.Chi-square test was used to compare the differences between the rates,and the difference P<0.05 was considered statistically significant.Results From 2020 to 2022,48 of the 326 water samples in Xide County were qualified,with a total qualified rate of 14.72%.Water supply units in Xide County were mainly small water supply stations.The qualified rate of total coliform was low(14.72%).The qualified rate of drinking water in high water season was lower than that in low water season(χ^(2)=6.254,P=0.012).Conclusions The qualified rate of drinking water in Xide County is low,and the main reason is excessive microorganisms.The management of drinking water disinfection should be strengthened,and the management mechanism should be improved,in order to ensure the health of the masses.
