吉林省通榆、乾安县承压地下水氟污染的原因及其防治对策

The cause of Tongyu-Qianan, Jilin province confined groundwater fluorine pollution and control countermeasure

本文针对吉林省通榆、乾安县潜水高氟地区下部第四系承压地下水氟含量升高 ,引起氟地方病重新抬头的环境水文地质问题 ,分析了氟升高的原因 ,主要是在开发第四系承压地下水的过程中含水层顶板的大规模破坏 ,使高氟潜水下窜 ,污染了深层承压水所致。对防治对策进行了探讨。提示人们在水资源开发过程中应保护开采层的地球化学环境 。

Because of the lower part of Quaternary confined groundwater fluorine content increases in the Tongyu, Qianan, Jilin province, phreatic high fluorine area, which the endemic fluorosis resumes. The cause is that the roof of confined water was damaged on a large scale when exploiting the Quaternary confined groundwater, resulting in downseepage and polluting deep phreatic water of phreatic water with high fluorine. In this paper, the cause of confined groundwater fluorine pollution and its prevention and control countermeasure are discussed. We need to take precautionary measures to protect geochemical environment of the exploitiation strata when developing the water resources, and we should draw a lesson from the part disastrous effects resulted from the destructive nature.
