目的了解宜昌市点军区农村饮用水卫生现状,发现问题,整改重点安全隐患,确保农村居民用水安全。方法 2011-2013年,分别于枯水期和丰水期对点军区10个农村集中式供水点的出厂水和末梢水进行监测。监测按照《生活饮用水标准检验方法》(GB/T 5750-2006)[1]进行,结果评价按照《生活饮用水卫生标准》(GB/T 5749-2006)[2]进行。结果 2011-2013年共监测农村饮用水120份,水质合格28份,合格率为23.33%;不同年份间水质合格率比较差异无统计学意义(χ2=3.94,P>0.05);其中枯水期、丰水期合格率分别为23.33%和23.33%(χ2=0.60,P>0.05)。合格率较低的主要是总大肠菌群、菌落总数和硝酸盐氮。结论点军区农村饮用水水质污染较重,需加强农村生活饮用水水源的保护和管理,同时加强农村饮用水水质日常卫生监督检测,确保百姓饮用水安全。
Objective To understand the status quo of rural drinking water hygiene in Yichang Military Region, discover the problems, rectify the key safety problems and ensure the safety of rural residents. Methods From 2011 to 2013, the factory water and the peripheral water in 10 rural centralized water supply points in the PLA military area were monitored during the dry and wet periods respectively. The monitoring was conducted in accordance with the Standard Test Method for Domestic Drinking Water (GB / T 5750-2006) [1], and the results were evaluated in accordance with the Standard for Drinking Water Quality (GB / T 5749-2006) [2]. Results A total of 120 drinking water samples were collected from rural areas during 2011-2013, with 28 samples qualified and 23.33% qualified. There was no significant difference in passing rates between different years (χ2 = 3.94, P> 0.05) The qualified rate of water phase was 23.33% and 23.33% respectively (χ2 = 0.60, P> 0.05). The low pass rate is mainly the total coliforms, the total number of colonies and nitrate nitrogen. Conclusion The military drinking water quality in the military region is relatively heavy. The protection and management of drinking water sources in rural areas should be strengthened. At the same time, daily sanitary supervision and testing of drinking water quality in rural areas should be strengthened to ensure people’s drinking water safety.
