摘要

PROBLEM TO BE SOLVED: To provide an oil decomposing device and method which enable the efficient decomposition and removal of oil in a short time by neither generating hazardous substances nor requiring regeneration treatment and auxiliary fuel, and a purification method for oil-contaminated groundwater using the oil decomposing method.;SOLUTION: The oil decomposing device comprises an oil treatment means capable of treating oil, and an ozone supply means capable of supplying ozone to the oil treatment means. In the oil decomposing method, oil permeates through the oil treatment means to which the ozone has been supplied. The purification method for oil-contaminated groundwater uses the above oil decomposing method.;COPYRIGHT: (C)2008,JPO&INPIT
