通过收集宿南矿区水文地质资料,采集矿井水样品进行测试,进一步对研究区矿井水水化学特征、阳离子交替吸附作用以及灌溉适宜性进行分析评价。结果显示,宿南矿区矿井水呈弱碱性,矿化度高,水化学类型主要为HCO3-Na型,地下水存在正向离子...通过收集宿南矿区水文地质资料,采集矿井水样品进行测试,进一步对研究区矿井水水化学特征、阳离子交替吸附作用以及灌溉适宜性进行分析评价。结果显示,宿南矿区矿井水呈弱碱性,矿化度高,水化学类型主要为HCO3-Na型,地下水存在正向离子交换且研究区矿井水不能直接用于农业灌溉,需要进行化学处理。By collecting hydrogeological data from the southern mining area of Suzhou and collecting mine water samples for testing, the chemical characteristics, cation exchange adsorption, and irrigation suitability of the mine water in the study area were further analyzed and evaluated. The results show that the mine water in the Sunan mining area is weakly alkaline with high mineralization, and the hydrochemical type is mainly HCO3-Na type. The groundwater has positive ion exchange, and the mine water in the study area cannot be directly used for agricultural irrigation and needs chemical treatment.展开更多
