| 摘 要： | 总硬度是北京市浅层地下水水质超标最显著的影响因素,在地下水水质评价中占有重要地位。本文在多年来地下水水质监测资料的基础上,选取代表性监测井点进行分析,结果表明总硬度呈逐渐增高趋势。通过对总硬度变化的机理进行分析,总硬度升高的根本原因在于地下水的不合理开发利用及保护,是钙镁离子浓度、pH值、Cl-、溶解性总固体、总碱度等因素综合作用的结果。

| Abstract: | As the most obvious factor leading to poor groundwater quality,total hardness is important in groundwater evaluation.Based on the monitoring data of groundwater quality,the representative wells were chosen to analyze the tendency of total hardness.The results show that there is an increasing tendency of the total hardness.According to the analysis of fundamental mechanism,a conclusion is drawn that the increase of total hardness is attributed to the unreasonable development and protection and th... |
