摘要:目的 了解和掌握农村安全饮水工程水质卫生状况及其变化趋势,为改善农村饮水安全工程的水质卫生状况和预防介水传染病提供科学依据。方法 按照《全国农村饮水安全工程水质监测技术方案》实施,数据经“中国疾病预防控制信息管理系统”上报,数据审核后导出,用EXCEL表格建立数据库,统计分析运用SPSS16.0统计软件包处理。结果 2008—2013年共监测10 648个工程,工程日供水≤ 200 m3的工程占84.82%;饮水完全处理的工程占9.42%,占比呈逐年上升趋势(?2= 84.04,P<0.01)。共监测42 592份水样,合格8 828份,合格率为20.73%,呈逐年上升趋势(?2=5.87,P<0.05)。出厂水合格率高于末梢水(?2=7.43,P<0.01);枯水期合格率高于丰水期(?2=691.60,P<0.01);以地面水为水源的水样合格率高于以地下水为水源的水样合格率(?2=17.31,P<0.01);完全处理的水样合格率高于其他供水方式水样合格率(?2=3382.78,P<0.01);使用液氯消毒的水样合格率高于使用其他消毒剂处理的水样(?2=4126.54,P<0.01);水样合格率随工程日供水能力增加而上升(?2=2194.72,P<0.01)。单项指标合格率低于90%的指标有:总大肠菌群、肉眼可见物、菌落总数、浑浊度四个指标。结论 云南农村安全饮水工程以日供水规模较小的工程为主,供水方式逐年改善,但完全处理的工程占比仍较低。水质合格率呈逐年上升趋势,但仍低于全国平均水平,微生物和一般感官性状不合格是水质合格率较低的主要原因。

Abstract: Objective In order to understand the sanitary situation and variation on the quality of rural drinking water and to provide scientific data for improving the water quality and preventing water-borne diseases. Methods The basic situation of water supplies in rural drinking water safety projects was investigated and water samples were collected according to the National Sanitary Surveillance Scheme for Rural Drinking Water Projects. All input data were verified by the National Disease Control Information System, and were downloaded and analyzed with SPSS 16.0.  Results  A total of 10648 water safety projects were surveyed in 2008?2013. The daily water supply capacity in 84.82% of projects was equal or less than 200 m3,and completed treatment facilities were provided only in 9.42% of projects, and which was increased year by year( ?2=84.04,P<0.01). Eighteen indexes were detected for 42592 water samples, the quality of only 8828 (20.73%) water samples reached the standard for drinking water in China, but the qualified rate increased year by year (?2=5.87, P<0.05). The qualified rate of treated water was higher than tap water (?2=7.43,P<0.01), the qualified rate in dry period was higher than that in wet period (?2=691.60, P<0.01); the qualified rate of water original from surface water as water source was higher than the water original from underground water as water source (?2=17.31, P<0.01), the qualified rate of completely treated water was higher than the water treated by other ways (?2=3382.78,P<0.01), the qualified rate of water disinfected by liquefied chlorine was higher than other disinfectants (?2=4126.54,P<0.01), the qualified rate of water was improved with the increase of daily water supply capacity (?2=2194.72,P<0.01). The items for the qualified rate lower than 90% were total coli forms, visible substances, total bacteria counts and turbidity in 18 examined indexes. Conclusions The daily water supply capacity of most projects in this study was in a small-scale, the ways of water treatment were improved year by year, however, the proportion of completed treatment was still very low. The qualified rate of water increased year by year, mainly due to the lower qualified rate on microbial indexes and general sensory characteristics.
