【摘要】：目的了解云南省农村中小学校饮用水现状,为制定学校饮用水安全措施提供科学依据。方法 2016年对云南省558所农村中小学校进行供水工程相关情况调查及水质检测。结果所调查的学校供水工程水源类型以地面水为主,占64.3%;工程消毒的仅有47.1%;枯水期水质合格率为53.1%,丰水期水质合格率为47.1%,差异有统计学意义(χ2=3.903,P0.05)。影响水质的主要指标为微生物、浑浊度和肉眼可见物;枯水期菌落总数、总大肠菌群、浑浊度和肉眼可见物,合格率分别为93.5%,61.8%,88.0%和92.8%;丰水期菌落总数、总大肠菌群、浑浊度和肉眼可见物合格率分别为86.9%,58.8%,82.8%,89.8%。结论云南省农村中小学校饮用水卫生状况不容乐观,应引起重视。可通过改善供水设施,提高消毒效果,加强相关知识宣传等措施,保证师生饮水安全。
[Abstract]:Objective to understand the present situation of drinking water in rural primary and secondary schools in Yunnan province and to provide scientific basis for making safety measures for drinking water in schools. Methods in 2016, 558 primary and middle schools in rural areas in Yunnan Province were investigated on water supply engineering and water quality. Results the main types of water sources in school water supply project were surface water (64.3%), and only 47.1% of them were disinfected. The qualified rate of water quality was 53.1 in dry season and 47.1 in abundant water, the difference was statistically significant (蠂 2 / 3.903 P 0.05). The main indexes affecting water quality were microorganism, turbidity and visible matter of naked eye, total colony, total coliform, turbidity and visible matter of naked eye in the dry season, the qualified rates were 93.5%, 88.0% and 92.8%, respectively. The qualified rates of total colony count, total coliform group, turbidity and visible matter in the naked eye were 86.9% and 58.8%, 82.8% and 89.8%, respectively. Conclusion the hygienic situation of drinking water in rural primary and secondary schools in Yunnan Province is not optimistic and should be paid more attention to. The safety of drinking water for teachers and students can be ensured by improving the water supply facilities, improving the disinfection effect and strengthening the propaganda of relevant knowledge.
