【摘要】：目的了解云南省農(nóng)村中小學(xué)校飲用水現(xiàn)狀,為制定學(xué)校飲用水安全措施提供科學(xué)依據(jù)。方法 2016年對云南省558所農(nóng)村中小學(xué)校進(jìn)行供水工程相關(guān)情況調(diào)查及水質(zhì)檢測。結(jié)果所調(diào)查的學(xué)校供水工程水源類型以地面水為主,占64.3%;工程消毒的僅有47.1%;枯水期水質(zhì)合格率為53.1%,豐水期水質(zhì)合格率為47.1%,差異有統(tǒng)計(jì)學(xué)意義(χ2=3.903,P0.05)。影響水質(zhì)的主要指標(biāo)為微生物、渾濁度和肉眼可見物;枯水期菌落總數(shù)、總大腸菌群、渾濁度和肉眼可見物,合格率分別為93.5%,61.8%,88.0%和92.8%;豐水期菌落總數(shù)、總大腸菌群、渾濁度和肉眼可見物合格率分別為86.9%,58.8%,82.8%,89.8%。結(jié)論云南省農(nóng)村中小學(xué)校飲用水衛(wèi)生狀況不容樂觀,應(yīng)引起重視。可通過改善供水設(shè)施,提高消毒效果,加強(qiáng)相關(guān)知識(shí)宣傳等措施,保證師生飲水安全。
[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.
