2016年荆门市某管理区洪涝灾害期间集中供水水质应急监测结果分析

Analysis of the results of water quality emergency monitoring in a district of Jingmen during floods

目的通过对荆门市某管理区洪涝灾害期间集中供水水质监测,了解该管理区洪涝灾害期间集中式供水水质现状,为洪涝灾害期间集中式供水应急处置提供科学依据,保障洪涝灾害期间居民饮水安全。方法依据GB 5749—2006对2016年辖区内农村安全饮水工程水质监测结果进行分析和评价。结果洪涝灾害期间共采集水质样品22份,其中合格5份,总合格率为9.44%。经统计学分析各次监测水样,总体合格率比较差异有统计学意义(χ~2=6.83,P<0.05),说明水质经应急处理后逐渐变好。结论洪涝灾害期间受灾地区各水厂水质监测结果合格率较低,很难达到卫生学意义上的"安全饮水",建议政府部门加强对自来水厂的监管,加大健康教育宣传力度,保障受灾地区居民的饮水安全。

Results A total of 22 water samples were collected and detected,and 5 samples were all qualified with the qualified rate of 9. 44%. The each batch of monitored sample was conducted for statistical analysis,with the difference of total qualified rate statistically significant（ χ~2= 6. 83,P 〈0. 05）,indicating that the water quality after emergency treatment was improved. Conclusion The qualified rates of drinking water from each water plant was low during the flood. It was difficult to meet the criteria of safe drinking water in the sense of hygiene drinking.
