REMEDIATION METHOD FOR HEAVY METAL CONTAMINATED SOIL

摘要

PURPOSE: A method for restoring soil contaminated with heavy metal is provided to improve the efficiency of a magnetic force-based separating process by implementing a soil aggregate dispersing process before the magnetic force-based separating process. CONSTITUTION: Soil contaminated with heavy metal is collected(10). Soil aggregates of the soil are dispersed into a plurality of separated soil particles by introducing the soil into a dispersing solution to release the cohesion of the soil(20). Suspension with the soil particles and the dispersing solution passes through magnetic field to separate the soil particles based on magnetic force(40). The soil particles are classified using a sieve by the sizes of the particles between the dispersing process and the magnetic force-based separating process(30).
