摘　　要：目的了解2012—2018年通辽市农村饮用水微生物污染状况,为改善水质提供科学依据。方法按GB/T 5750—2006《生活饮用水标准检测方法》进行检测,按GB 5749—2006《生活饮用水卫生标准》进行水质评价。结果 2012—2018年共检测通辽市7个区县农村饮用水水样3 790份,微生物指标总体达标率为70.158%,而且随年份达标率总体呈上升趋势(χ^(2)趋势=210.382,P<0.01)。绘制统计地图发现,通辽市奈曼旗饮用水微生物污染较为严重,其他区县微生物指标达标率均良好。经过处理的饮用水微生物指标达标率为92.806%,高于未处理的(69.248%),差异有统计学意义(χ^(2)=69.399,P<0.01)。结论通辽地区农村饮用水仍存在微生物污染问题,而且个别旗县污染还很严重,应加强对重点污染旗县水源地管理和增加生活饮用水的净化消毒处理,保障居民饮用水安全。Objective To understand the situation of microbial pollution of drinking water in rural areas of Tongliao City from 2012-2018,provide scientific basis for improving water quality. Methods Test was conducted according to GB/T 5750-2006 Standard Examination Methods for Drinking Water,and result was evaluated according to GB 5749-2006 Standards for Drinking Water Quality. Results From 2012-2018,a total of 3 790 water samples from seven counties/districts in Tongliao City were tested,the overall compliance rate of microbiological indexes was 70.158%,and the compliance rate increased with years (χ^(2)trend= 210.382,P<0.01). The statistical map indicated that the microbial pollution of drinking water in Naiman Banner of Tongliao City was more serious,and the compliance rates of microbial indexes in other districts and counties were good. The compliance rate of microbiological indexes in treated water(92.806%) was higher than that in untreated water(69.248%),and the difference was statistically significant(χ^(2)=69.399,P<0.01). Conclusion Microbial pollution still exists in rural drinking water in Tongliao,and some areas have serious pollution. It is necessary to strengthen the management of water sources of key polluted area and increase the purification and disinfection of drinking water,to ensure the safety of drinking water for residents.
