摘　　要：目的 分析2022年安徽省农村生活饮用水水质监测结果,为提升全省农村饮用水水质提供依据。方法 依据GB/T 5750—2006《生活饮用水标准检验方法》对2022年全省1 236个乡镇3 180个农村生活饮用水监测点的水样进行采集、保存和检测,以GB/T 5749—2006《生活饮用水卫生标准》为参考依据进行综合评价。使用SPSS 19.0统计软件对水质达标率进行统计分析。结果 2022年共采集农村饮用水水样6 918份,水质达标率为97.19%,枯水期水质达标率为97.27%,丰水期水质达标率为97.11%。以地表水为水源的水质达标率整体高于以地下水为水源的水质(χ2=39.515,P<0.001),水库水质达标率(99.27%)最高(χ2=56.464,P<0.001);供水规模在10 000 t/d以上的供水单位水质达标率(99.13%)最高(χ2=35.990,P<0.001)。微生物指标、消毒剂指标和氟化物指标达标率较低。结论 2022年安徽省农村生活饮用水水质状况整体良好,微生物指标、消毒剂指标和氟化物指标达标率有待进一步提高。Objective To analyze the monitoring results of rural drinking water quality in Anhui Province in 2022,and pro-vide a basis for strengthening the quality of rural drinking water in the province.Methods Water samples of 3180 town-ship-monitoring-sites in 1236 villages and towns were collected,stored and tested according to GB/T 5750-2006 Standard Test Method for Drinking Water,and results were evaluated by GB/T 5749-2006 Standard for Drinking Water Hygiene in 2022.SPSS 19.0 statistical software were used to analyze the data statistically.Results A total of 6918 samples of rural drinking water were collected in 2022,the water qualification rate was 97.19%,which was 97.27%in dry season and 97.11%in wet season,respectively.The water qualification rate of surface water was higher than that of underground water(x^(2)=39.515,P<0.001),reservoir water qualification rate was 99.27%,which was the highest of all water sources(x2-56.464,P<0.001).The water qualification rate with more than 10000 tons per day supply scale reached 99.13%,which was higher than that other scale water supply units(x^(2)=35.990,P<0.001).The qualification rate of microbial index,dis-infectant and fluoride were lower than that of other monitoring indicators.Conclusion In 2022,the quality of rural drinking water in Anhui Province was in good condition as a whole,and the compliance rate of microbial indicators,disinfectant indi-cators and fluoride indicators needs to be further improved.
