饮用水中氟浓度超标是导致地方性氟中毒疾病的主要因素。北京市通州区城镇及农村生活用水主要以地下水为主。通过水质资料综合分析,施工探采结合井及水质专项调查,开展了地下水中氟分布规律的研究,找到了氟在地下水中空间的分布规律,并简单分析了氟浓度超标的原因,为通州区今后水井的施工工艺选择提供了技术及理论支持,并为研究治理地下水中氟浓度超标的措施提供依据。
Excessive levels of fluoride in drinking water are the major contributors to endemic fluorosis. Tongzhou District, Beijing urban and rural areas mainly in groundwater-based water. Based on the comprehensive analysis of water quality data, exploration and mining combined with well and water quality survey, the study of fluorine distribution in groundwater was carried out and the distribution of fluorine in groundwater was found. The reasons for exceeding the fluorine concentration were briefly analyzed. In the future, the selection of construction technology of the well provides technical and theoretical support, and provides the basis for the study of measures to control excessive fluorine concentration in groundwater.
