西宁地区地下水硬度升高原因和机理探讨

Discussion on the cause and mechanism of the hardness increasing of Xining groundwater

本文就西宁地区地下水硬度增长情况,分别从其增长的主要物质来源和机理分析两方面予以讨论。笔者认为地下水硬度不断增长是过量开采地下水促使工业与生活的三废排放物同作为原生地质环境的碳酸盐、硫酸盐岩层和土壤发生化学反应的结果。并提出了防止地下水硬度增长的主要措施。

This paper discusses the hardness increasing of Xining groundwater. The main points of discussion ovre the material source and mechanism analysis of this increasing.The author considers that this gradual increasing of hardness is the result of the chemical reactions between the carbonate and sulphate rocks and soils with the three kinds of industrial and civil wastes. The rocks and soils being original geological environment, while the reactions are resulted from the over--extraction of groundwater. Finally, the author suggests measures to prevent this incrcasing of hardness.
