摘要
目的了解2015-2018年襄阳市二次供水水质卫生现状,为政府相关部门改善二次供水卫生质量提供科学依据。方法收集并分析2015-2018年襄阳市二次供水监测数据。结果2015-2018年共采集二次供水水样165份,样本总合格率为77.6%;经卡方检验,不同年度间水样合格率呈整体下降趋势(χ趋势^2=7.706,P=0.006);市区合格率(82.1%)大于县区合格率(45.0%),差异有统计学意义(P<0.05);消毒剂指标合格率最低(91.5%),其次为微生物指标合格率(95.7%),不同指标合格率差异有统计学意义(P<0.05)。结论襄阳市二次供水卫生现况不容乐观,应着力提高消毒剂指标合格率,降低二次供水被微生物污染的可能性,加强对县区二次供水的监督检查力度。
Objective To understand the sanitary status of drinking water of secondary supply in Xiangyang City from 2015 to 2018,and to provide scientific basis for relevant government departments to improve the sanitary quality of secondary water supply.Methods The monitoring data of secondary water supply in Mianyang city was collected and analyzed from 2015 to 2018.Results Total of 165 samples of secondary water supply were collected from 2015 to 2018,with a total qualified rate of 77.6%.Chi-square test showed that the qualified rate of water samples decreased in different years(χtrend^2=7.706,P=0.006);the qualified rate of urban area(82.1%)was higher than that of county area(45.0%).The lowest rate was 91.49%for disinfectant indicator,then it was followed by the qualified rate of microbial indicators(95.74%).Conclusion The sanitation problem of secondary water supply in Xiangyang city is not optimistic.We should focus on improving the qualified rate of disinfectant indicators,reducing the possibility of secondary water supply being polluted by microorganisms and strengthening the supervision and inspection of secondary water supply in counties.
