摘要
文章旨在了解北京市大兴区生活饮用水微生物污染状况,为提高生活饮用水标准和科学管理提供参考.文章对2019-2023年大兴区生活饮用水监测点进行水样采集和微生物指标检测,并对检测结果的卫生安全性进行评价.此次共检测2019-2023年大兴区饮用水样2 254份,合格2120份,合格率达94.06％.结果显示,不同年度水样合格率差异有统计学意义(P＜0.001);不同来源水样合格率差异有统计学意义(P＜0.001);不同水期水样合格率差异有统计学意义(P＜0.001).研究表明,大兴区城区市政供水卫生状况较好,但农村地区的饮用水水质仍有待提高.
Abstract
The paper aims to understand the microbial contamination status of drinking water in Bejing Daxing District,and provide references for improving the standards and scientific management of drinking water.water samples are collected and microbial indicators are tested at the drinking water monitoring points in Daxing District from 2019 to 2023.A total of 2 254 drinking water samples in Daxing District are tested,of which 2120 are qualified,with a qualification rate of 94.06％.There is a statistically significant difference in the qualification rate of water samples from different years(P＜0.001).There is a statistically significant difference in the qualification rate of water samples from different sources(P＜0.001).There is a statistically significant difference in the qualified rate of water samples from different water periods(P＜0.001).The results show that the sanitation status of municipal water supply in the urban area of Daxing District is relatively good,but the drinking water quality in rural areas still needs to be improved.
