摘　　要：目的:分析讨论某地区2021—2023年农村生活饮用水中微生物指标的检测结果,评估水质安全状况,并提出改进对策。方法:在该地区设置水质监测点,每年丰水期和枯水期各采集一次水样,共检测394份水样。检测指标包括细菌总数、总大肠菌群以及大肠埃希菌,依据《生活饮用水卫生标准》(GB 5749—2006)进行评价。结果:该地区农村生活饮用水2021—2023年不合格率呈现出逐年下降的趋势,总不合格率为18.02%。不同水期(丰水期和枯水期)的微生物指标不合格率也呈现出逐年下降的趋势。结论:该地区农村生活饮用水的水质安全状况有一定程度改善,但仍需要针对水质加强监测和管理,为农村居民的饮水提供安全保障。Objective:To analyze and discuss the detection results of microbial indicators in rural drinking water from 2021 to 2023 in a certain area,evaluate the water quality safety status,and propose improvement measures.Method:Water quality monitoring points were set up in this area.Water samples were collected once a year in wet season and dry season,and a total of 394 water samples were detected.The total number of bacteria,total coliform and Escherichia coli were evaluated according to the GB 5749—2006.Result:The unqualified rate of rural drinking water in this area from 2021 to 2023 showed a decreasing trend year by year,and the total unqualified rate was 18.02%.The unqualified rate of microbial indexes in different water periods(wet period and dry period)also showed a decreasing trend year by year.Conclusion:The water quality safety of rural drinking water in this area has been improved to a certain extent,but it is still necessary to strengthen monitoring and management of water quality to provide safety guarantee for rural residents.
