摘　　要：目的了解辽宁省农村生活饮用水微生物污染现状,为提高微生物达标率及有效控制介水传染病提供依据。方法 2014—2019年,设置覆盖农村乡镇90%以上的监测点,于枯水期和丰水期分别采集出厂水和末梢水,检测样本微生物指标、统计水源类型和消毒情况。结果 2014—2019年辽宁省农村生活饮用水达标率为79.88%。不同年份达标率比较,差异有统计学意义(P<0.05);枯水期达标率(84.96%)大于丰水期(74.79%),差异有统计学意义(P<0.05);出厂水达标率(81.55%)高于末梢水(78.51%),差异有统计学意义(P<0.05);各水源类型水样达标率差异有统计学意义(P<0.05),水源为深井水时达标率最高为87.51%;消毒水样达标率(95.21%)高于未消毒水样(77.61%),差异有统计学意义(P<0.05)。结论 2014—2019年辽宁省农村生活饮用水仍存在微生物污染情况,应规范水质消毒处理。Objective To understand the current status of microbiological contamination in drinking water in rural areas of Liaoning Province,provide a basis for improving the standard-reaching rate of microorganisms and effectively controlling waterborne infectious diseases. Methods The monitoring points covering more than 90% of rural towns and villages were set up from 2014-2019,and the factory water and peripheral water during the dry and wet periods were collected respectively,to test the microbial indicators of the samples,and count the types of water sources and disinfection conditions. Results The standard-reaching rate of drinking water in rural areas of Liaoning Province from 2014-2019 was 79.88%,and there was statistically significant difference in annual standard-reaching rate(P<0.05). The standard-reaching rate in dry season(84.96%) was higher than that in dry season(74.79%),and the difference was statistically significant(P<0.05). The standard-reaching rate of factory water(81.55%) was higher than that of peripheral water(78.51%),and the difference was statistically significant(P<0.05). There was a statistically significant difference in the standart-reaching rate of water samples with different water source types,and the standard-reaching rate was the highest(87.51%) when the water source was deep well water. The standard-reaching rate of sterilized water samples(95.21%) was higher than that of unsterilized water samples(77.61%),and the difference was statistically significant(P<0.05). Conclusion There is still microbial contamination in drinking water in rural areas of Liaoning Province from 2014-2019,and water quality disinfection should be standardized.
