| 摘要 |
<p>The present invention relates to a method of removing deposited pollutant oil using air, and more particularly to a method of removing pollutant oil, which comprises injecting compressed air when oil has been deposited at the bottom of the sea, and injecting compressed air while supplying water when oil has been deposited on water-free sand, rock or soil, thereby degassing the oil while floating the remaining degassed oil on the water surface. More specifically, the method: introducing an air jet at the bottom below the water surface; injecting compressed air from the air jet, thereby raising water and sand or soil together with the compressed water, discharging gas by the kinetic energy of air bubbles caused by the compressed air flow to degas oil, and floating the degassed oil on the water surface; and removing the floated oil.</p> |
