单县地下水中氟的分布及饮水安全

Fluorine Distribution in Groundwater and Drinking Water Safety in Shanxian

通过实地调查和水样采集分析,研究山东省单县地下水中氟的分布及高氟水的成因,分析研究区饮水安全现状。结果表明：研究区内大部分地区氟含量超标,氟含量为1.1-3.5 mg·L^-1;影响氟在该区含水层中迁移转化的因素主要包括水文地质条件、气候及径流条件和地下水化学因素等。针对该区实际情况,提出合理化改水降氟建议。

In China,drinking-water type fluorosis is distributed widely. Based on field investigation and water sample collection,fluorine distribution in groundwater and influencing factors,as well as drinking water situation in Shanxian of Shandong Province are studied. The results show that high fluoride water is widely distributed in this area. In most of regions fluorine content is beyond the allowable limit and fluorine concentration of groundwater in Shanxian ranges from 1. 1 mg/L to 3. 5 mg/L. Fluorine migrate and transform in the aquifer are affected by hydro-geological conditions,climate conditions,and runoff and groundwater chemical factors. In this article countermeasures for water improvement are put forward considering the actual situation of the studied area.
