| 摘 要： | 为分析白城市浅层地下水氟含量的分布特征和富集机理,采用Piper三线图、Kringing插值、Pearson分析、氯碱指数、Gibbs图等方法讨论了研究区F-分布规律和富集机理。结果表明,长石类矿物的溶解为F-富集提供了碱性环境。研究区F-浓度由外部向内部增大,其对应的主要水化学类型由HCO3-Ca·Na型过渡至HCO3-Na型。地下水化学成分的形成作用成为制约地下水氟富集的重要因素。方解石的沉淀和石膏的溶解影响着萤石的溶解与沉淀,蒸发浓缩作用和离子交换作用为最终高氟地下水中阳离子是Na+提供了依据。

| Abstract: | In order to analyze the distribution characteristics and enrichment mechanism of fluorine content in the shallow groundwater of Baicheng City,the F-distribution and enrichment mechanism in the study area are discussed by means of Piper trigraph,Kringing interpolation,Pearson analysis and Chlor-alkali index Gibbs.The results show that the dissolution of feldspar minerals provides an alkaline environment for F-enrichment.The concentration of F-in the study area increased from the outside to the inside,and the corresponding main hydrochemical types were transferred from HCO3-Ca·Na type to HCO3-Na type.The formation of groundwater chemical composition is an important factor restricting fluorine enrichment in groundwater.The precipitation of calcite and the dissolution of gypsum affect the dissolution and precipitation of fluorite.Evaporation and concentration and ion exchange provide the basis for Na+in the final high fluoride groundwater. |
