集雨型水窖不同深度水质差异研究

Study on Water Quality Difference in Different Depths of Rainwater Collecting Cellar

黄土高原作为我国重要的能源基地,水资源因煤炭开采、水土流失遭到严重破坏。山西柳林县位于黄土高原纵深腹地,将作为本文研究基点。本文从柳林县王家山村选取集雨砖砌水窖,用水泵抽取泥土地表对应水窖不同深度的窖水。用多参数水质分析仪测量水质指标pH、TDS、EC、ORP,参照国家饮用水标准作了水质比较,探索居民饮用的窖水是否符合用水标准。结果表明,水窖中不同深度的水质不同,水质指标均正常且符合国家饮用水标准。本研究为政府部门从事非常规水资源的开发和利用提供理论指导。

As an important energy base in China,the water resources in the Loess Plateau have been seriously damaged by coal mining and soil erosion.Liulin County,Shanxi Province is located in the deep hinterland of the Loess Plateau,which will be the research base of this paper.In this paper,the rainwater collecting brick cellar was selected from Wangjiashan Village,Liulin County,and the cellar water with different depths corresponding to the cellar on the soil surface was pumped by water pump.The water quality indexes such as pH,TDS,EC and ORP were measured by a multi-parameter water quality analyzer,and the water quality was compared with the national drinking water standard,so as to explore whether the cellar water consumed by residents met the water standard.The results show that the water quality in different depths of water cellar is different,and the water quality indexes are normal and meet the national drinking water standards.This study provides theoretical guidance for government departments to engage in the development and utilization of unconventional water resources.
