摘要
目的分析某区域生活饮用水微生物检测结果。方法针对某区域2022年送检的77份水样(其中60份农饮水、17份城饮水)以及2023年送检的88份水样(其中74份农饮水、14份城饮水)进行研究,根据《生活饮用水标准检验方法》对以上水样进行菌落总数、总大肠菌群、耐热大肠菌群的检测,比较相关差异。结果(1)2022年、2023年微生物指标合格率为73.94%;2022年水样77份,检测出细菌总数、总大肠菌群、耐热大肠菌群、三项综合合格率分别是62.34%,58.44%,58.44%,58.44%;2023年水样88份,细菌总数、总大肠菌群、耐热大肠菌群、三项综合合格率分别是87.50%,87.50%,88.63%,87.50%。(2)2022年、2023年农饮水总合格率为56.67%、60.81%。2022年、2023年城饮水总合格率为94.12%、92.86%;2022年、2023年农饮水、城饮水合计细菌总数、总大肠菌群、耐热大肠菌群、三项合计合格率比较,差异有统计学意义(P﹤0.05)。结论根据抽样检查的结果,城饮水的合格率仍然未达到100%,农饮水的合格率比城饮水的更低,存在严重的水污染问题,相关部门在今后应加强水质监管,积极完善消毒工作。
Objective To analyze the microbial detection results of drinking water in a certain area.Methods 77 water samples submitted for inspection in 2022(including 60 for agricultural drinking water and 17 for urban drinking water)and 88 water samples submitted for inspection in 2023(including 74 for agricultural drinking water and 14 for urban drinking water)were studied.The total number of bacterial colonies,total coliforms and thermostable coliforms were detected according to the Standard Inspection Method for Drinking water.Compare the relevant differences.Results(1)The qualified rate of microbial indexes in 2022 and 2023 was 73.94%;In 2022,77 water samples were collected,and the total number of bacteria,total coliform,heat-resistant coliform and three comprehensive passrates were 62.34%,58.44%,58.44%,58.44%,respectively.The total number of bacteria,total coliform,thermostable coliform and the comprehensive pass rates of 88 water samples in 2023 were 87.50%,87.50%,88.63%and 87.50%,respectively.The total qualified rate of agricultural drinking water in 2022 and 2023 is 56.67%and 60.81%.The total qualified rate of urban drinking water in 2022 and 2023 is 94.12%and 92.86%;In 2022 and 2023,the total number of bacteria,total coliform,heat-resistant coliform and three total pass rates of agricultural drinking water and urban drinking water were compared,and the difference was statistically significant(P<0.05).Conclusion According to the results of sampling inspection,the qualified rate of urban drinking water is still not 100%,the qualified rateof rural drinking water is lower than that of urban drinking water,there are serious water pollution problems,relevant departments should strengthen the supervision of water quality in the future,and actively improve the disinfection work.
