TREATING METHOD FOR WASTE

摘要

PROBLEM TO BE SOLVED: To provide a treating method which enhances the recovering efficiency of heavy metals by suppressing the elution of the heavy metals while maintaining a high desalting effect in washing treatment of wastes such as dust. SOLUTION: The treating method for desalting the wastes containing chlorine and heavy metals by flushing the wastes, in which the wastes are flushed by maintaining the pH of the aqueous slurry (aqueous suspension) of the wastes at a range of 8.5 to 13 to desalt the wastes by suppressing the elution of the heavy metals.
