摘要:目的 了解四川省阿坝州农村饮水安全工程水质卫生状况,为制定卫生政策提供科学依据。方法 2009—2011年在枯水期和丰水期,分别对阿坝州7个县63个已建成农村集中式饮用水安全工程点采集的出厂水及末梢水进行水质监测检验分析。结果 3年共监测检验水样252份,总体合格率为34.92%,2009、2010、2011年水样合格率分别为26.67%、58.33%和28.03%(χ2 = 19.52,P < 0.01)。枯水期与丰水期水质合格率分别为57.94%、11.90%(χ2 = 58.20,P < 0.01)。水质检测指标中,主要以总大肠菌群、耐热大肠菌群、肉眼可见物、菌落总数超标为主。调查的63座农村饮用水安全工程中,水源类型以地表溪水为主占82.53%,水处理以沉淀过滤为主占96.83%。结论  阿坝州农村集中式供水水质合格率较低,微生物污染是重要原因,工程水处理设施不完善,水质未经消毒处理;应加快农村生活饮用水安全工程建设和水处理工艺的完善,加强对农村饮用水卫生的监督监测和水质消毒,保障农村饮用水卫生安全。

Abstract: Objective To find out the quality and hygienic status of water in the Rural Drinking Water Safety Project in Aba Prefecture, and provide scientific basis for the government to formulate health policy. Method The quality of treated water and peripheral water collected from 63 monitoring points in seven counties of Aba Prefecture in dry season and wet period in 2009–2011 was inspected. Result  A total of 252 water samples were monitored and inspected in these three years.  The total pass rate was 34.92%; the pass rates in the years 2009, 2010 and 2011 were 26.67%, 58.33% and 28.03%, respectively (χ2 = 19.52, P < 0.01), and those in the dry season and wet period were 57.94% and 11.90%, respectively (χ2 = 58.20, P < 0.01). Among the water quality indexes detected, the total coli forms, heat-resistant coli forms, visible matters, the total number of colonies exceeded the standard limits. The water sources of 63 monitoring sites were mainly surface water from streams (82.53%), and the water was treated mainly by precipitation and filtration (96.83%). Conclusion The qualified rate of rural centralized water supply in Aba Prefecture was low; microbial contamination was one of the most important reasons, and the imperfect water engineering and treatment facilities and no disinfection measures were also problems. Accelerating the Rural Drinking Safety Projects, improving the construction and water treatment technology, strengthening hygienic supervision and monitoring and water disinfection to protect rural drinking water safety are necessary.
