目的了解广元市城区饮用水水源卫生现状,发现问题并提出建议,更好的保证饮用水卫生安全。方法对广元市城区5个水厂的水源地进行现场调查,查阅分析西湾水厂水源水质监测报告。结果调查广元市城区5个以嘉陵江为水源水的水厂,60%的水源地划分明确,按照距离由近及远依次为一级、二级和准水源保护区,明确设立了标志牌,标明地域范围及其禁止进行的活动,并有专人进行定时和不定时巡查,密切监测水源安全状况。80%的水源地周围存在采砂活动,且堆砂较多;另外,80%的水源与高速公路、铁路相互交叉、伴行,时刻面临交通事故特别是危化品的威胁。结论广元市城区居民生活饮用水水源卫生状况总体上安全,水质良好,但也存在小规模供水水厂水源保护较差,水源保护区划定不规范,无备用水源等问题。
Objective To understand the sanitary status of drinking water sources in urban areas of Guangyuan City, find out the problems and make recommendations to better ensure the hygiene and safety of drinking water. Methods A field investigation was conducted on the water sources of five waterworks in Guangyuan City, and the water quality monitoring report of SaiWan Waterworks was consulted. Results Five waterworks with Jialing River as source water were surveyed in Guangyuan City. 60% of the water sources were well-defined. According to the distance, the first, second and quasi-water source protection areas were set up with signs Geographical scope and activities prohibited by them, and conduct regular and irregular inspections by hand to closely monitor the safety of water sources. There are sand mining activities around 80% of the water sources and more sand is piled up. In addition, 80% of the water sources cross the expressways and railways and accompany each other. They are always threatened by traffic accidents, especially dangerous chemicals. Conclusions The health status of drinking water sources for urban residents in Guangyuan City is generally safe and the water quality is good. However, there are also some problems such as poor protection of water sources in small-scale water supply plants, non-standardization of water source protection zones, and lack of backup water.
