目的了解肥城市农村生活饮用水卫生情况,为保障农村集中式供水水质的安全提供依据。方法于2013年1—12月对肥城市山区14个乡(镇)的28个农村集中式供水点分别在丰水期与枯水期进行动态的水质监测和一般的卫生学调查。结果 28个采样点共采集水样56份,按《生活饮用水标准检验方法》分别进行了14个项目的检验,被检测水样14项指标全合格的有29份,合格率为51.79%。丰水期与枯水期大肠菌群和细菌总数合格率分别为35.70%、35.70%、71.40%、67.90%,两期比较差异均有统计学意义(P<0.05)。结论农村饮用水微生物污染是农村生活饮用水不合格的主要原因。
Objective To understand the sanitary conditions of drinking water in rural areas in Feicheng City and provide the basis for ensuring the safety of centralized water supply in rural areas. Methods From January to December 2013, 28 rural centralized water supply points in 14 townships (towns) of Feicheng City were monitored for dynamic water quality and general hygiene in wet season and dry season, respectively. Results A total of 56 water samples were collected at 28 sampling points. 14 items were tested according to “Standard Test Method for Domestic Drinking Water”. 29 of the 14 items tested were all qualified, with a pass rate of 51.79%. The pass rates of coliform bacteria and bacteria in wet and dry periods were 35.70%, 35.70%, 71.40% and 67.90% respectively, with significant difference between the two phases (P <0.05). Conclusion Microbial contamination of rural drinking water is the main reason for the unqualified drinking water in rural areas.
