目的了解青铜峡市农村生活饮用水卫生质量和状况,为农村生活饮用水监管和科学改水提供依据。方法应用青铜峡市生活饮用水卫生监督预警控制平台,收集2010-2014年农村生活饮用水管网水监测数据并进行统计分析。结果共检测水样342份,合格205项次,合格率59.94%,不同年份合格率差异无统计学意义(χ~2=8.839,P>0.05);浑浊度、铁、锰、硫酸盐、氟化物等主要指标超标(χ~2=175.963,P<0.05);丰水期和枯水期的合格率无统计学意义(χ~2=3.040,P>0.05);集中供水和分散供水的合格率差异有统计学意义(χ~2=5.510,P<0.05)。结论农村生活饮用水水质总合格率较低,应引起高度重视,加强农村生活饮用水卫生管理和监测工作,提高全民用水卫生意识。
Objective To understand the hygienic quality and status of rural drinking water in Qingtongxia City and provide the basis for the regulation of drinking water in rural areas and the scientific improvement of water quality. Methods Qingtongxia City drinking water health monitoring and early warning control platform, collected from 2010 to 2014 rural drinking water network water monitoring data and statistical analysis. Results A total of 342 water samples were tested, with 205 qualified passes and a pass rate of 59.94%. There was no significant difference in pass rates between different years (χ ~ 2 = 8.839, P> 0.05); turbidity, iron, manganese, (Χ ~ 2 = 175.963, P <0.05). There was no significant difference between the wet season and the dry season (χ ~ 2 = 3.040, P> 0.05). The difference of qualified rates between centralized water supply and decentralized water supply There was statistical significance (χ ~ 2 = 5.510, P <0.05). Conclusion The overall qualified rate of drinking water quality in rural areas is relatively low, which should be given high priority. Health management and monitoring of drinking water in rural areas should be strengthened to raise the public awareness of water use.
