摘要
大庆市齐家水源地井口现场和实验室测定的地下水水质参数与其真实情况存在差异 .运用水文地球化学手段模拟了地下水从含水层被抽出至地表的过程中由于所承受压力降低不可避免地导致CO2 ,H2 S等气体的逸出 ,从而影响 pH ,Eh的测定结果 .最后指出了地下水采样测试技术的发展方向 .
The groundwater quality parameters determined both at the well head and in the laboratory of Qijia water supply base, Daqing city, differ from what happens in the real situation. Hydrogeochemical method is used to simulate the changes of pH and Eh values due to the inevitable degassing of CO 2 and H 2S resulting from the pressure drop in the course of the groundwater pumping from the water_bearing bed to the earth surface. The trends in the groundwater sampling are proposed in the final part of the paper.
