Vigorous physical effects including micro-jet and micro-streaming can be induced in heterogeneous systems by acoustic cavitation. This can be useful for the removal of pollutants from contaminated soil particles. In this study, the diesel removal efficiencies in ultrasonic, mechanical, and combined soil washing processes have been compared considering the electrical energy consumptions for these processes. The combined process showed synergistic effects for both removal efficiency and effective volume also has the advantage of a short operation time compared to the sequential processes. Thus the ultrasonic soil washing process with mechanical mixing is considered a promising technology for industrial use.
在多相体系中，声空化可产生强大的物理效应，包括微射流和微流动。这对于去除污染土壤颗粒中的污染物非常有用。在本研究中，考虑到这些过程的电能消耗，比较了超声、机械和联合土壤洗涤过程中去除柴油的效率。与顺序过程相比，联合过程在去除效率和有效体积方面均表现出协同效应，并且具有操作时间短的优点。因此，带机械搅拌的超声土壤洗涤过程被认为是一种有前途的工业技术。
