PARTICLE SIZE SELECTIVE REMEDIATION SYSTEM AND METHOD FOR HEAVY METALS-CONTAMINATED SOILS BY DRY-DISINTEGRATION AND SEPARATION

摘要

PURPOSE: A particle size-selective purification system of heavy metal polluted soil and a purification method using the same are provided to simplify operational processes by classifying polluted soil and purifying the classified polluted soil. CONSTITUTION: A particle size-selective purification system of heavy metal polluted soil is composed of a pre-treating unit(110), a disintegration unit(120), a classifying unit(130), a dry heavy metal eliminating unit(140), and a separation and collecting unit(150). The disintegration unit disintegrates soil into particles under a dry state. The classifying unit classifies the soil by particle sizes. The dry heavy metal eliminating unit strips the surface of the soil to eliminate heavy metals. The separation and collecting unit collects the stripped surface of the soil.
