Title:
METHOD AND APPARATUS FOR DETOXIFYING DIOXIN POLLUTED PARTICLE
Document Type and Number:
Japanese Patent JP2008272539
Kind Code:
A
Abstract:
To provide a method and apparatus capable of always efficiently detoxifying pollutant of soil or the like polluted with dioxin up to a sufficient level.
Particles polluted with dioxin are classified by a method including the mutual rubbing of the particles or the contact with a moving fluid (S1-S3). A particulate sample collected at the same place is trially classified in advance to measure the concentration of dioxin at every particle size and, on the basis of the measuring result, a set particle size is determined. The particles with the set particle size or below in the classified particles are chemically treated to detoxify dioxin (S5-S8) and the particles exceeding the set particle size are not chemically treated (S4).
