摘　　要：分析甘肃省农村饮用水水质监测数据和供水工程信息,为农村饮用水卫生安全保障提供依据。基于甘肃省2018—2023年农村集中式供水工程水质监测数据,运用水质指数评价法比较水质差异,采用卡方检验比较各年度间供水工程状况。结果表明:甘肃省农村集中供水工程的自动化监控系统和净化消毒设施配备比例、水质综合指标达标率都有所提高,各年度间差异均有统计学意义(P<0.05)。在单项监测指标中,2018—2023年微生物指标中总大肠菌群总达标率由68.66%提升到了90.95%,感官性状指标中浑浊度合格率由92.26%提升到了98.65%。2018—2023年甘肃省农村饮用水供水状况有所改善,供水水质呈上升趋势,应继续推进供水工程规模化、标准化建设,保障饮用水卫生安全。Objective To analyze the monitoring data of rural drinking water quality and water supply project information in Gansu Province,and to provide a basis for the guarantee of rural drinking water health security.Methods Based on the water quality monitoring data of rural centralized water supply project in Gansu Province from 2018 to 2023,the water quality index evaluation method was used to compare the differences in water quality,and the chi-square test was used to compare the status of water supply projects in each year.Results The results showed that the automatic monitoring system,the proportion of purification and disinfection facilities,and the comprehensive index of water quality in rural centralized water supply project in Gansu Province were improved,and the differences between each year were statistically significant(P<0.05).In the single monitoring index,the total standard rate of total coliforms in microbial index increased from 68.66% to 90.95% from 2018 to 2023,and the turbidity qualified rate in sensory index increased from 92.26% to 98.65%.Conclusion The rural drinking water supply situation in Gansu from 2018 to 2023 was improved,and the water quality was on the rise.It is necessary to continue to promote the scale and standardization construction of water supply project to ensure the health safety of drinking water.
