郑州市浅层地下水中Hg(Ⅱ)、As(Ⅲ)的污染机理研究

Study on Pollution Mechanism of Hg(II), As(m) of Shallow Groundwater in Zhengzhou City

本文在研究郑州市地质、环境水文地质条件基础上.根据Hg(Ⅱ)、As(Ⅲ)在浅层地下水中时、空分布特征的现状评价结果,以及室内实验、数学模型的运算,论证了造成郑州市浅层地下水中Hg(Ⅱ)、As(Ⅲ)污染的主要原因,并提出防治措施。

Major causes for forming Hg(Ⅱ), As(Ⅲ) pollutions in shallow ground water of Zhengzhou city and prevention measures are verified based on the study of geological and environmental hydrogeological conditions of the said city, together with the evaluation results of present situation of time and spatial distribution of Hg(Ⅱ), As(Ⅲ) in shallow ground water as well as the calculations of laboratory experiment and mathematical model.
