摘要
目的 分析江苏盐城区域生活饮用水微生物检测结果.方法 选取2021年1月—2023年12月盐城市盐都区疾病预防控制中心的953份饮用水样本为研究对象,严格根据相关要求,完成所有饮用水样本的微生物检测工作,并统计检测不合格情况.结果 953份饮用水样本中,微生物检测不合格率为9.50%.不同年度不合格率比较,差异无统计学意义(P均>0.05).相较枯水期,丰水期水质不合格率(7.33%)更高,差异有统计学意义(χ2=9.590,P<0.05).相比出厂水与末梢水,二次供水检测不合格率更高,差异有统计学意义(P均<0.05).结论 盐城市盐都区域生活饮用水微生物检测不合格率比较低,丰水期水质和二次供水水质略差,需加强水质管理,严格消毒处理,保证生活饮用水质量.
Abstract
Objective To analyze the microbial detection results of drinking water in Yancheng of Jiangsu province.Methods A total of 953 drinking water samples from Yancheng Yandu District Center for Disease Control and Preven-tion from January 2021 to December 2023 were selected as the study objects.In strict accordance with the relevant re-quirements,the microbial testing of all drinking water samples were completed,and unqualified testing were counted.Results In 953 samples of drinking water,the unqualified rate of microbial detection was 9.50%.There was no signifi-cant difference in the unqualified rate among different years(all P>0.05).Compared with dry season,the unqualified rate of water quality in wet season was higher(7.33%),and the difference was statistically significant(χ2=9.590,P<0.05).Compared with factory water and peripheral water,the unqualified rate of secondary water supply detection was higher,and the differences were statistically significant(both P<0.05).Conclusion The microbial detection unquali-fied rate of drinking water in Yandu of Yancheng City is relatively low,the water quality and secondary water supply water quality are slightly poor,water quality management should be strengthened,strict disinfection treatment should be implemented to ensure the quality of drinking water.
