Title:
METHOD FOR PURIFYING DIOXIN-CONTAMINATED SOIL
Document Type and Number:
WIPO Patent Application WO/2021/049745
Kind Code:
A1
Abstract:
The present invention provides a method for purifying dioxin-contaminated soil, comprising the steps of: (a) collecting dioxin-contaminated soil; (b) adding, to the collected soil, Novosphingobium pentaromativorans US6-1, which is a microorganism, and microorganism nutrients, and mixing same; (c) sealing the soil mixed with the microorganism; (d) maintaining the sealed condition for 1-12 months; (e) unsealing the soil which has been sealed for the period, further adding Novosphingobium pentaromativorans US6-1, which is a microorganism, and microorganism nutrients, and mixing same; and (f) periodically turning over the soil for 1-20 weeks in an environment in which oxygen is supplied and the relative humidity is maintained at 20-40%.
