摘要：

Air sparging can remediate contaminated soil using biodegradation and volatilization effect. This paper investigates the direct visualization of injected air and the resistivity monitoring for air sparging. Behavior of air flow in a simulated soil composed of plexiglas particles was observed, photographed and videotaped. We found the particle size and compaction affect the air flow. Air flows up as channels whose shape can be described as a parabola in fine particles. We applied resistivity tomography to monitor the air flow during air sparging in laboratory. We found the resistivity change resulted from the change in saturation by the injected air.
