目的了解和掌握内蒙古赤峰市阿鲁科尔沁旗地区农村生活饮用水卫生现状,为政府有关部门决策提供科学依据。方法对2009～2011年在全区范围内开展调查,根据各县区不同的供水方式(集中式、分散式),不同饮用水源,人口所占比例共设置141个监测点,每年的枯水期(3～5月)和丰水期(7～9月)对监测点地下水质进行采样分析,检测指标为水质感官指标、一般化学指标、毒理学指标和细菌学指标,设计统一调查表对农村供水类型、取水方式和水源类型及其覆盖人口进行调查。结果农村饮用水水源类型以地下水为主,占92.5%,集中式供水覆盖人口占30.8%;2009～2011年抽测合格率82.5%。其中,微生物指标合格率82.5%,感官性状和一般化学及毒理学指标合格率100%(297/297)。不合格指标:总大肠菌群、细菌总数、粪大肠菌群。农村生活饮用水中总大肠菌群合格率水平在38.89%～56.67%之间。结论阿鲁科尔沁旗地区农村生活饮用水水质受动物粪便和生活污水污染严重,加强对饮用水水源卫生防护和水质消毒是关键措施。
Objective To understand and grasp the sanitary status of rural drinking water in Aruk’erqin Banner area, Chifeng City, Inner Mongolia, and provide a scientific basis for the decision-making of relevant government departments. Methods A total of 141 monitoring sites were set up according to the different water supply modes (centralized and decentralized) in different counties and districts, and the proportions of different sources of drinking water and population from 2009 to 2011. The annual dry season ( March to May) and wet season (July to September), the sampling and analysis of the groundwater quality at the monitoring sites were carried out. The detection indexes were water quality sensory indexes, general chemical indexes, toxicological indexes and bacteriological indexes. Type, type of water intake and type of water sources and their coverage of population survey. Results The types of drinking water in rural areas were mainly groundwater, accounting for 92.5% of the total. The population covered by the centralized water supply was 30.8%. The sampling pass rate in 2009-2011 was 82.5%. Among them, the qualified rate of microbial indicators 82.5%, sensory traits and general chemical and toxicological indicators pass rate of 100% (297/297). Failure indicators: the total coliform bacteria, the total number of bacteria, fecal coliform. The prevalence of total coliform bacteria in rural drinking water ranged from 38.89% to 56.67%. Conclusion The water quality of drinking and drinking water in rural areas of Aruk’erqin Banner is seriously polluted by animal manure and domestic sewage, and it is the key measure to strengthen the sanitation protection and water quality disinfection of drinking water sources.
