Abstract
A reductive heating treatment test using pilot scale equipment was carried out to develop an on-site decontamination process for POPs in polluted soil at lower temperatures. The pilot-scale test confirmed the reduction of BHCs from 2,354 μg/kg to 0.31 μg/kg for contaminated soil, namely removal rate of 99.99% at 550℃ for one hour under an oxygen deficient atmosphere. The content of Dioxins in treated water and gas from the reductive heating equipment also met the Japanese regulations.
