摘要
以淮北平原浅层地下水中的氟离子为研究对象,在分析地形地貌、水文地质条件、地下水化学成分(总硬度、矿化度、氟离子等)、水化学类型特征等基础上,运用统计方法分析了氟离子浓度与pH值、K++Na+浓度、Ca2+浓度、ρ(K++Na+)/ρ(Ca2+)比值、Mg2+浓度之间的关系。结果表明氟离子浓度随地下水pH值的增大而增大,与ρ(K++Na+)/ρ(Ca2+)比值之间存在着正相关关系,但是与K++Na+浓度、Ca2+浓度、Mg2+浓度之间并无明显的相关性。最后讨论了氟离子的影响因素,提出合理利用地下水的建议。
After analyzing the topography and geomorphology, the hydrogeological conditions, the chemical components （total hardness, salinity, and fluorine ion）, and the hydro-chemical characteristics of the shallow groundwater in the Huaibei Plain, this study analyzed the F^- content variation with pH, the total content of K^＋ and Na^＋ , the Ca^2＋ content, the （K^＋ ＋ Na^＋ ）/Ca^2＋ ratio, and the Mg^2＋ content using statistical methods. It was found that that the F^- content increases along with the pH value and is linearly related to the （K^＋ ＋ Na^＋ ）/Ca^2＋ ratio, but no apparent correlation has been found between the F^- content and the total K^＋ and Na^＋ content, the Ca^2＋ content, or the Mg^2＋ content. This paper also discusses the factors affecting F^- and gives suggestions for reasonable utilization of groundwater resources.
