【摘要】：目的掌握羅平縣農(nóng)村飲用水安全工程水質(zhì)衛(wèi)生狀況,為預(yù)防控制水性疾病和飲用水公共衛(wèi)生事件提供可靠依據(jù)。方法根據(jù)《云南省農(nóng)村飲用水水質(zhì)衛(wèi)生監(jiān)測技術(shù)方案》的要求,按照《生活飲用水衛(wèi)生標(biāo)準(zhǔn)檢驗方法》(GB/T5750-2006)進(jìn)行水樣采集和檢測,《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》(GB5749-2006)進(jìn)行結(jié)果評價。結(jié)果2011-2014年共檢測供水點80個,各年檢測20個供水點,檢測水樣320份,合格水樣37份,合格率僅為11.6%。不合格項目主要為微生物指標(biāo),合格率枯水期為12.5%,豐水期為10.6%;合格率比較差異無統(tǒng)計學(xué)意義(χ~2=0.275,P0.05)。水源類型有地面水和地下水,其中地面水276份,地下水44份,微生物指標(biāo)地面水合格率為3.3%,地下水合格率為63.6%,地下水合格率明顯高于地面水(χ~2=50.833,P0.005);感官性狀指標(biāo)地面水合格率為77.5%,地下水合格率為100.0%,差異具有統(tǒng)計學(xué)意義(χ~2=12.250,P0.005)。一般化學(xué)指標(biāo)地面水合格率為92.8%,地下水合格率為100.0%,差異無統(tǒng)計學(xué)意義(χ~2=3.401,P0.05)。結(jié)論羅平縣農(nóng)村飲用水微生物污染是主要的衛(wèi)生問題。目前建設(shè)的農(nóng)村安全飲水工程,只是改變了供水方式,供水未處理現(xiàn)象普遍存在,應(yīng)引起有關(guān)部門的高度重視,建議加強對農(nóng)村集中式供水的管理和監(jiān)督。
[Abstract]:Objective to understand the water quality hygiene status of rural drinking water safety project in Luoping County, and to provide reliable basis for prevention and control of water-borne diseases and drinking water public health events. Methods according to the requirements of Yunnan Rural drinking Water Sanitation Monitoring Technical Scheme, water samples were collected and detected according to the Sanitary Inspection method for drinking Water (GB/T5750-2006). The results were evaluated by the Sanitation Standard for drinking Water (GB5749-2006). Results from 2011 to 2014, 80 water supply points were detected, 20 water supply points were detected in each year, 320 water samples were tested, 37 qualified water samples were qualified, and the qualified rate was only 11.6%. The unqualified items were mainly microbial indexes, the qualified rate was 12.5% in low water period and 10.6% in abundant water period, and there was no significant difference in qualified rate (蠂 ~ 2 / 0.275, P0.05). The qualified rate of surface water and groundwater is 3.3% and 63.6%, respectively. The qualified rate of groundwater is obviously higher than that of surface water (蠂 ~ 2 ~ 50.833, 蠂 ~ 2 ~ 50.833, P < 0.05), the qualified rate of ground water is 3.3%, and the qualified rate of groundwater is 63.6% (蠂 ~ 2 ~ 2 ~ 50.833). P0.005); The qualified rate of surface water and groundwater were 77.5% and 100.0% respectively. The difference was statistically significant (蠂 ~ 2, 12.250, P0.005). The qualified rate of surface water and groundwater were 92.8% and 100.0%, respectively. There was no significant difference (蠂 ~ 2 / 3.401, P0.05). Conclusion microbial contamination of rural drinking water in Luoping County is a major health problem. At present, the safe drinking water project in rural areas has only changed the way of water supply, and the phenomenon of unhandled water supply is widespread, which should be attached great importance to by the relevant departments, and it is suggested that the management and supervision of centralized water supply in rural areas should be strengthened.
