目的了解宜昌市农村集中式供水卫生状况,为政府及相关部门决策提供科学依据。方法收集2015年宜昌地区农村集中式供水枯水期和丰水期出厂水、末梢水监测资料进行分析。结果在监测的546份水样中,合格水样315份,合格率为57.7%;地表水源与地下水源水样合格率的差异有统计学意义(χ~2=6.40,P<0.05),出厂水与末梢水合格率的差异无统计学意义(χ~2=1.77,P<0.05),枯水期与丰水期合格率的差异有统计学意义(χ~2=44.60,P<0.01)。结论宜昌市农村饮用水卫生状况不佳,应强化消毒效果,杀灭水中微生物,能有效提高农村饮用水水质合格率。
Objective To understand the centralized sanitation of rural water supply in Yichang City and provide a scientific basis for the government and relevant departments to make policy decisions. Methods The water supply and peripheral water monitoring data of rural centralized water supply in Yichang in 2015 and dry season were collected for analysis. Results Among the 546 water samples monitored, 315 were qualified and the pass rate was 57.7%. There was a significant difference in the passing rate of surface water samples and groundwater samples (χ ~ 2 = 6.40, P <0.05) There was no significant difference in the qualified rate of water between the water and the terminal water (χ ~ 2 = 1.77, P <0.05), and there was a significant difference in pass rate between the dry and wet periods (χ ~ 2 = 44.60, P <0.01). Conclusion Poor health status of rural drinking water in Yichang City should strengthen the disinfection effect and kill microorganisms in water, which can effectively improve the passing rate of rural drinking water.
