| 摘 要： | 目的]探讨地质封存CO_2泄露对地表水中非金属类物质指标的影响,为相关研究提供理论依据。方法]通过控制二氧化碳泄露时间、泄露速率、泄漏时的温度等条件,分析其对地表水中pH值、溶解氧(DO)、HCO-3和化学需氧量(COD)等指标的影响。结果]一定时间内,二氧化碳泄露对pH值和DO的影响最大,对HCO-3和COD的影响较小;泄露速率的增大将提高pH,DO,HCO-3的反应速率,即加快pH值和DO的下降,加快了HCO-3的升高;而温度的升高对COD的影响最大。结论]建议将地质封存CO_2的监测指标选取为地表水中的pH值、DO和HCO-3,因为此三者的变化明显。

| Abstract: | Objective] Studying the effect of CO2 leakage during geological storage on non-metallic surface water in order to provide a theoretical basis for the related research. Methods] By changing the leakage time, leakage rate, and the temperature of carbon dioxide, we studied the impacts on pH value, DO, HCO3- and COD of surface water. Results] The leakage of CO2 affected pH and DO value greatly, whereas its effects on HCO3- and COD were relatively small. Increasing of leakage rate could accelerate the reaction rate of pH, DO and HCO3-, thereby pH and DO declined faster, and HCO3- increased more quickly. However, temperature rising had the greatest impact on COD content. Conclusion] It suggests that pH, DO and HCO3-, as their sensitive reaction to CO2, could be used as the surface water monitoring indicators for CO2 geological storage. |
