摘要
以湖北省武汉市长江新城起步区为研究区,针对不同含水层的主要离子含量、地下水化学类型、地下水质量等特征进行分析,总结研究区地下水环境特征,并对地下水污染影响因素进行综合分析。结果表明研究区地下水环境整体一般,阳离子以Ca^2+为主,阴离子以HCO-3为主,水化学类型以HCO 3-Ca·Mg型为主。地下水质量总体为Ⅳ类,局部达Ⅲ类,受赋存地层的原生环境和人类活动双重影响,区内近长江沿岸的孔隙承压水Fe、Mn含量超标,部分农业种植区地下水氨氮超标,部分工业场区地下水总硬度、硝酸盐超标。
Taking the Yangtze River New Town as the research area,the main ion content,chemical types and quality of groundwater were analyzed chemical type and groundwater quality were analyzed,the characteristics of groundwater environment in the study area were summarized,and the influencing factors of groundwater pollution were comprehensively analyzed.The results show that: the groundwater environment in the study area is general as a whole,the cations are mainly Ca2+,the anions are mainly HCO-3,and the hydrochemical type is mainly HCO3-Ca·Mg type.The groundwater quality is class Ⅳ in general and class Ⅲ in some parts.Due to the double influence of natural background and human activities,the content of Fe and Mn in the Quaternary confined water near the Yangtze River in the area exceeded the standard,the ammonia nitrogen and oxygen consumption of groundwater exceeded standard in some agricultural plantation areas,and the total hardness and the dissolved total solids exceeded in some industrial areas.
