摘要
本文论述了江苏丰沛铜地区Ⅲ承压含氟地下水形成的地质、水文地质条件及水化学环境,阐明了Ⅲ承压水含氟量与水文地质要素和水化学组份之间的关系,指出了Ⅲ承压水在本区地氟病改水防治中的意义。
The groundwater in Fengxian,Peixian and Tongshan counties can be divided into pore water in loose rocks,Karst-fissure water in carbonatites and fissure water in clastic or mag- matic rocks according to its formation,and buried conditions.The Ⅲ confined water belongs to pore water in loose rocks and its fluorine content is closely related to the factors such as paleolandform,paleogeography,thickness and water amount in aquifers.The water-bearing beds,exceed 20 metres in thickness is mainly distributed in the regions of paleocauce with good run-off condition,rich water amount,wide feed range.Therefore,the fluorine ions in groundwater can easily move and reach a low content.
