沈阳地区2017年地下水水化学类型评价与分析
|
摘要
随着地下水利用的增加,地下水类型成为影响使用方式和效率的重要指标。通过对2017年沈阳地区地下水进行水化学类型的评价,得到沈阳地区水化学类型以CⅢCa型为主,各县区分布略有不同,说明沈阳地区地下水为河流沉积平原的孔隙水,以碳酸盐岩为主。通过对酸碱度、总硬度、溶解性总固体和硝酸盐氮的数据进行分析,说明沈阳地区地下水阴阳离子平衡,硬度较大,口感一般并有一定污染情况。
With increasing of groundwater utilization, the types of groundwater has become an important indicator affecting the way of use and efficiency. Through the evaluation of hydrochemical types of groundwater in Shenyang in 2017, the type of water chemistry in Shenyang is mainly CⅢCa type. The distribution of each county is slightly different, indicating that the groundwater in Shenyang is a pore water of river sedimentary plains, with carbonates. The main rock. By analyzing the pH value, total hardness, total dissolved solids, and nitrate nitrogen, it is shown that groundwater has a balance of cations and cations in Shenyang, with high hardness, general taste, and is certain pollution.
