PURPOSE : An ultrasound oxidation hybrid soil purification system and a method are provided to reduce the amount of usage of an oxidant as an ultrasound to reduce the secondary pollution caused by the usage of chemicals and reduce the amount of sludge treatment by letting the fine earth and sand rising separate by bubble.CONSTITUTION : An ultrasound oxidation hybrid soil purification system comprises a selecting apparatus(110); an ultrasound oxidation washing tub(120); an after selecting apparatus(130); and a floating device(140). The selecting apparatus distributes the soil into droplet sizes from the excavated and polluted soil. The ultrasound oxidation washing tub washes the distributed soil crop using the ultrasound and oxidant. The after selecting apparatus distributes the washed soil into droplet sizes. The floating apparatus separates the fine earth and sand from the soil flowed from the after selecting apparatus with bubble.COPYRIGHT KIPO 2013
