摘要
为分析罗定市农村地区生活饮用水的微生物状况,本文采集了2018—2019年罗定市农村地区生活饮用水样品,按生活饮用水标准检验方法对其进行检验和评价。结果显示,在采集的268份水样中,微生物综合指标合格率为78.4%(210/268),其中出厂水、末梢水合格率分别为85.3%(81/95)和77.1%(128/166),井水和管网水合格率为0.0%(0/1)和16.7%(1/6),差异有统计学意义(P<0.05)。年份之间、月份之间综合指标合格率差异无统计学意义(P>0.05)。由此可知,罗定市农村地区生活饮用水存在一定程度的微生物污染,应针对污染严重的供水单位及其设施进行整治,以确保农村地区生活饮用水的安全。
In order to analyze the microbial status of drinking water in rural areas of Luoding city and provide evidence for the supervision of drinking water safety in rural areas.In this paper,samples of drinking water in rural areas of Luoding city from 2018 to 2019 were collected,tested and evaluated according to the standard of drinking water testing methods.The result showed that during the total of 268 water samples collected,the qualified rate of comprehensive microbiological indicators was 78.4%(210/268).Among them,the qualified rates of factory water and peripheral water were 85.3%(81/95)and 77.1%(128/166).The qualified rate of water in the pipe network was 0.0%(0/1)and 16.7%(1/6),and the difference was statistically significant(P<0.05).There was no significant difference in the passing rate of comprehensive indicators between the years and between months(P>0.05).It can be seen that there is a certain degree of microbial contamination of drinking water in rural areas of Luoding city,and water supply units and facilities with severe pollution should be rectified to ensure the safety of drinking water in rural areas.
