大同盆地高氟地下水水化学特征及其成因OA北大核心CSCDCSTPCD
Hydrochemistry and Occurrence of High Fluoride Groundwater in Datong Basin
为查明控制大同盆地高氟地下水形成的主要地球化学过程,对大同盆地地下水高氟区31个水样进行了水化学特征及因子分析研究.结果表明,研究区浅层和深层地下水中均检测出氟,且氟含量高,最大ρ(F)达10.37 mg/L.该区高氟地下水以Na-HCO3型水为主,具有典型的富Na特征.PHREEQC饱和指数计算结果表明,地下水中萤石为不饱和状态,地下水中ρ(F)主要受到萤石溶解影响.因子分析研究表明,水一岩相互作用、碳酸盐矿物溶解沉淀及Na- Ca离子交换作用…查看全部>>
To identify the main geochemical processes controlling the fluoride enrichment in groundwater at Datong Basin, total of thirty-one samples were collected for hydrochemical and factor analysis study. High fluoride concentration was detected in both shallow and deep groundwater. In shallow groundwater, the fluoride concentration ranges from 0. 01 to 10. 37 mg/L, while deep groundwater has lower fluoride concentration, ranging from 0. 01 to 3. 14 mg/L. High flu…查看全部>>
