| Modeling of Hydrogeochemical Environment in the Qijia Water Resource Base Area, Daqing |
| CO 2 and H 2S escape in large quantities during the pumping of groundwater in the Qijia water resource base area of Daqing, and hence E h and pH values measured near the well fail to reflect the real environment of groundwater. This paper presents a method for restoring hydrogeochemical environment by means of chemical and thermodynamic modeling. Environmental indices (pH,E h,CO 2 and H 2S) are qualified. pH values are lower than 6.56,E h values are between -121 mV and -145 mV,CO 2 values are higher than 300 mg/L, H 2S(aq) values are higher than 64 μg/L, and HS- values are higher than 17 μg/L. So water in the Qijia water resource base area of Daqing is weakly acid and weakly reductive with high CO 2 and certain amounts of H 2S. The method also provides guidance for disposal of underground Fe. |
