摘要:

北京市大兴区供水以地下水为主,研究该区高氟地下水的分布规律及其成因,对指导区域地下水的开发利用和保障居民饮水安全是必要的。在野外调查和以往研究成果的基础上,测试了北京大兴区地下水氟离子浓度。结果表明,高氟水分布区地层岩性以粘性土为主;浅层高氟水主要分布在大兴区的南部及东南部,超标区面积为258.57 km2;深层高氟水主要分布在中部,超标区面积为20.91 km2。建议对浅层高氟地下水加大止水深度,统一并严格设计饮用水井结构;对深层氟超标水,避免饮用或采取降氟措施后再饮用。

Abstract:

Water supply in Daxing district of Beijing mainly comes from groundwater, and it is necessary to discuss the distribution law and genesis of high fluorine groundwater for guiding groundwater development and ensuring drinking water safety. Based on field survey and previous research, concentrations of fluoride ion of groundwater from Daxing district of Beijing are measured. The results show that high fluorine water is distributed mainly in cohesive soil, that high fluorine water of shallow layer with 258.57 km2 exceeding fluorine national standard is distributed mainly in south and eastsouth of Daxing district, and that high fluorine water is distributed mainly in central section with 20.91 km2 exceeding fluorine national standard. Two suggestions are given in this paper as the following: (1) the stopdepth of shallow highfluoride water should be increased, and the structure of drinking water wells should be strictly integrated and designed; (2) the deep highfluoride water should avoid  being drunk or should be drunk after decreasing fluoride content.
