目的了解钦南区农村饮水安全工程水质卫生状况,为选择安全水源及水处理方式,预防控制饮水性疾病的发生提供科学依据。方法按照《广西农村饮用水卫生监测技术方案》进行实施。结果监测65个农村集中式供水点,检测260份水样,枯水期合格率为49.23%,丰水期合格率为33.08%。细菌总数枯水丰水期合格率分别为89.23%和74.62%;总大肠菌群枯水丰水期合格率分别为96.92%和52.31%;耐热大肠菌群枯水丰水期合格率分别为96.92%和54.62%,枯水丰水期水质监测中以上指标合格率比较,差异有统计学意义(P<0.01)。结论钦南区农村饮水安全工程水质合格率低。影响水质的主要因素是微生物指标超标,有关部门应加强监管。
Objective To understand the status of water quality and hygiene of rural drinking water safety project in Qinnan District and provide scientific basis for selecting safe water sources and water treatment methods and preventing and controlling waterborne diseases. Methods According to “Guangxi rural drinking water health monitoring technology program” to implement. Results 65 rural centralized water supply points were monitored and 260 water samples were tested. The passing rate in dry season was 49.23% and that in wet season was 33.08%. The total passing rate of bacteria in dry season was 89.23% and 74.62%, respectively. The passing rates of total coliform bacteria in dry and wet periods were 96.92% and 52.31% respectively. The passing rates of heat-resistant coliform bacteria in dry and wet periods were 96.92% and 54.62%, respectively. There was a significant difference in the passing rate of the above indexes in the water quality monitoring during dry seasons (P <0.01). Conclusion Qinan District, rural drinking water safety project qualified rate is low. The main factor that affects water quality is that the indicators of microorganisms exceed the standard, and relevant departments should strengthen supervision and control.
