杭州市北郊潜水含水层水土系统氟的污染研究

Fluorine contamination study of the aquifer water-soil system in northern suburb, Hangzhow City

本文通过对杭州市北郊潜水含水层水、土体系氟的吸附—解吸、迁移转化、水化学稳定场及氟的污染源研究,得出了含水系统氟主要以溶解态、吸附态和结合态三种形态存在,它们在水、土系统中的相互转化,主要通过吸附—解吸等化学平衡作用,以及水、土系统中氟的污染源主要来自气源氟等重要结论。

This paper makes a study of the adsorption-deadsorption, migration transformation, stabilizing field of water-chemistry and contamination origin of fluorine of the aquifer water-soil system in northern suburb of Hangzhou City. It concludes that fluorine in this water-bearing system exists chiefly in three forms dissoluable, adsobable and combining. It also confirms that their mutual transformation in the water-soil system is chiefly actuated by the chemical balance of adsorptiondeadsorption, and that the fluorine contamination origin in this system mainly comes from the gaseous fluorine etc.
