本研究旨在探讨利用电阻率层析成像技术(ERT)提高喷气后空气饱和度和溶解氧浓度的有效区域。进行了两次土槽试验。一种是向饱和自来水的新鲜土壤模型中注入空气，这是另一种试验的对照。另一种是向饱和了细菌溶液的石油污染土壤模型中注入空气。将空气直接注入各模型1小时后，测量土壤中空气饱和度和溶解氧的变化。喷雾后的空气饱和度与溶氧浓度有关。综上所述，ERT估算的空气饱和度分布是估算喷气后溶解氧浓度提高的有效区域的有效信息。
This study aimed to investigate the effective area where the air saturation and the dissolved oxygen concentration after air sparging can be enhanced using electrical resistivity tomography (ERT). Two soil tank tests were conducted. One was that air was injected to fresh soil model saturated with tap water, and this was control for the other test. The other was that air was injected to oil-contaminated soil model saturated with bacterial solution. Air was directly injected into each model for an hour, then the change of the air saturation and dissolved oxygen in the soil after that was measured. The air saturation after air sparging was related to the dissolved oxygen concentration. In conclusion, the air saturation distribution evaluated by ERT was an effective information to estimate the effective area where the dissolved oxygen concentration is enhanced after air sparging.
