目的通过对榆中县农村饮用水卫生现状的调查,为改进水质提供科学依据。方法在榆中县选择13个乡镇进行水源类型、供水方式等调查;每个乡镇选择3~4个采样点进行水样的采集和检测。结果 13个乡镇农村居民有56.82%以地表水为水源,43.18%以地下水为水源;从供水方式上看,有70.45%饮用集中式供水,29.55%饮用分散式供水。共检测水样44件,合格21件,合格率为47.73%。微生物指标特别是菌落总数合格率较低是影响水质的主要因素。结论微生物污染是榆中县农村饮水的主要卫生问题。
Objective To investigate the status quo of rural drinking water health in Yuzhong County and provide a scientific basis for improving water quality. Methods In Yuzhong County, 13 villages and towns were selected for the investigation of water source type and water supply method. Each township selected 3 ~ 4 sampling points for water sample collection and testing. Results 56.82% of rural residents in 13 townships used surface water as their source of water and 43.18% of them used groundwater as their source of water. From the point of view of water supply, 70.45% concentrated drinking water and 29.55% decentralized water were used for drinking water supply. A total of 44 water samples were tested, qualified 21, with a pass rate of 47.73%. Microbial indicators, especially the total number of colonies lower pass rate is the main factor affecting water quality. Conclusion Microbial contamination is the main health problem of rural drinking water in Yuzhong County.
