目的 分析蚌埠市2019—2022年农村饮用水卫生状况，为改善农村饮用水卫生状况提供科学依据。方法 收集蚌埠市2019—2022年农村生活饮用水监测数据，应用水质综合指数（WQI）评价农村饮用水水质。结果 共检测农村水样1 259份，WQI的中位数为0.63（0.52，0.76），水质优良率为94.36%，呈逐年上升趋势（ {\chi }_{趋势 }^2=27.515，P<0.001）。枯水期水质优良率高于丰水期（χ²=9.287，P=0.020）；大型供水工程（日供水≥1 000 m³）水质优良率高于小型供水工程（日供水<1 000 m³）（χ²=20.075，P<0.001）；按要求使用消毒设备水质优良率高于未按要求使用（χ²=29.639，P<0.001）。影响水质卫生状况的主要指标为氟化物、耗氧量、菌落总数等。结论 蚌埠市2019—2022年农村生活饮用水水质良好，水质状况主要受水期类型、供水工程规模、消毒设备是否按要求使用的影响。

Objective To analyze the rural drinking water sanitation status in Bengbu from 2019 to 2022, and to provide scientific basis for improving the rural drinking water sanitation status. Methods The monitoring data of rural drinking water in Bengbu from 2019 to 2022 were collected, and the water quality index (WQI) was used to evaluate the quality of rural drinking water. Results A total of 1 259 rural water samples were tested, the median (P₂₅, P₇₅) of WQI was 0.63 (0.52, 0.76). The excellent water quality rate was 94.36%, showed an upward trend year by year (χ {}_{trend }^2=27.515, P<0.001). The excellent water quality rate during the dry season was higher than that during the wet season (χ²=9.287, P=0.020). The excellent water quality rate of large-scale water supply projects (daily water supply≥1 000 m³) was higher than that of small-scale water supply projects (daily water supply<1 000 m³) (χ²=20.075, P<0.001). The excellent water quality rate of using disinfection equipment as required was higher than that of not using disinfection equipment as required (χ²=29.639, P<0.001). The main influencing indicators of water quality and sanitation status were fluoride, oxygen consumption, and total bacterial count. Conclusion The rural drinking water quality in Bengbu from 2019 to 2022 is good. The water quality is mainly affected by the type of water period, the scale of the water supply project, and whether the disinfection equipment was used as required.
