摘要
The present invention relates to a soil cleaning method and apparatus for restoring the selection process of the polluted soil.; The present invention method is a wet selection, primary cleaning, second washing stage and contaminated soil remediation process consisting of dehydration by the high-pressure water spray, starting from the first step of dry sorting drive the contaminated soil and; The contaminated cleaning fluid is generated in the wet screening step of the first, second washing stage collection was precipitated first made of a cohesive, secondary precipitation, neutralization and re-supply the sludge screen and the washing cycle consisting of the steps of, to implement this for apparatus, it consists of a dry sorting machines, high-pressure water spray selector, a drum-shaped first washing tank, screw feed type second washing tank, a centrifugal dehydrator, a primary settling tank, flocculation tank, the secondary sedimentation tank, neutralization tank and a filter press or the like.; Soil cleaning method of the present invention is rotated, as opposed to the body and made of a cleaning fluid radially sprayed and the cleaning efficiency can be improved by first washing tank cleaning fluid sprayer of stirring the wash liquid, effective classification of the particulate soil by the agitator in the second washing tank this cleaning and recovery efficiency of the contaminated soil is expected to be significantly improved because.
