Title:
PARTICLE SIZE SELECTIVE REMEDIATION SYSTEM AND METHOD FOR HEAVY METALS-CONTAMINATED SOIL BY DRY-DISINTEGRATION AND SEPARATION
Document Type and Number:
WIPO Patent Application WO/2013/141619
Kind Code:
A1
Abstract:
The present invention relates to a system and method of remediating heavy metal-contaminated soil using dry disintegration in a particle size-selective manner. The system for remediating contaminated soil comprises: a pretreatment unit for pretreating the contaminated soil to control the water content and the size of the soil; a disintegration unit for disintegrating the pretreated soil into individual particles; a particle separation unit for separating the disintegrated particles a standard particle size; a heavy metal removal unit for peeling off the surface of the separated soil particles larger than the standard particle size using a surface friction force and an impact force to remove heavy metals in dry condition; and a separation and collection unit for separating and collecting the peeled-off surface from the soil particles.
