目的了解武平县农村山泉水和井水水质卫生状况,为农村饮用水安全工程改水规划提供依据。方法收集2007—2011年17个乡镇村民送检水样1 622份,按2006年《生活饮用水标准检验方法》、《生活饮用水卫生标准》检测、评价。结果共检测20项指标,其中色度、浑浊度、臭和味、肉眼可见物、pH值、锰、铁、氟化物、硝酸盐氮、氨氮、亚硝酸盐氮(“三氮”)、微生物指标(菌落总数、总大肠菌群、耐热大肠菌群)12项超标,其余项目100.0%合格。“三氮”、微生物指标合格率山泉水均比井水高。结论井水水质受环境污染较严重。农村饮用水安全工程改水进度须加快、范围要加大。
Objective To understand the sanitary quality of mountain spring water and well water in Wuping County and provide basis for water diversion planning in rural drinking water safety project. Methods A total of 1 622 water samples collected from 17 townships and towns in 2007-2011 were collected and tested according to 2006 “Standard Test Method for Domestic Drinking Water” and “Sanitary Standard for Drinking Water”. Results Totally 20 indexes were tested, including color, turbidity, odor and taste, macroscopic, pH value, manganese, iron, fluoride, nitrate nitrogen, ammonia nitrogen and nitrite nitrogen , Microbial indicators (total number of colonies, total coliforms, heat-resistant coliform) 12 exceeded, the remaining 100.0% qualified. “Three nitrogen ”, microbial indicators pass rate spring water are higher than well water. Conclusion Well water quality is seriously polluted by the environment. Rural drinking water safety project to speed up the progress of water, the scope should be increased.
