皖北某市地下水水质变化特征分析

Analysis of the variation features of the groundwater quality in a city in northern Anhui

地下水是重要的自然资源,其水量、水质密切关系到人类生活和经济建设。为树立和践行“绿水青山就是金山银山”的理念,坚持节约资源和保护环境的基本国策,使城市更快更好地发展,本文通过对2018—2020年皖北某市的地下水水质数据进行分析,得出该市深层地下水水质好于浅层。地下水污染问题中,以无机污染问题最为突出,其中锰、氟、铁三类无机物指标超标严重;有机污染较轻。本文对该市地下水水质特征变化及污染情况进行了概括和分析,其研究成果为当地科学开发利用地下水资源提供参考依据。

As an important natural resource, groundwater is closely related to human life and economic construction in terms of its quantity and quality. In order to establish and practice the concept of "Clear water and green mountains are gold and silver mountains", adhere to the basic state policy of resource conservation and environmental protection, and make a city develop in a faster and better way, this paper analyzes the groundwater quality data of a city in northern Anhui from 2018 to 2020, and concludes that the deep groundwater quality of the city is better than the shallow one. Among the groundwater contamination problems, inorganic contamination is the most prominent, with the indicators of manganese, fluorine and iron exceeding the norms seriously, while the organic contamination is slight. Analysis of the variation features of the groundwater quality and contamination in this city provides a basis for scientific development and utilization of groundwater resources in the local area.
