METHOD FOR PURIFYING CONTAMINATED SOIL OR GROUNDWATER

摘要

PROBLEM TO BE SOLVED: To provide a purification method that is a soil or groundwater purification method for purifying soil or groundwater contaminated with organochlorine compounds and can achieve both cost reduction and efficiency improvement. ! SOLUTION: In a soil or groundwater purification method for purifying soil or groundwater contaminated with organochlorine compounds, the soil or groundwater contaminated with organochlorine compounds is purified by providing a heating process where soil is heated to 50-70°C, the organochlorine compounds are decomposed to low boiling point organochlorine compounds having the number of chlorine atoms smaller than that of the organochlorine compounds by cometabolism of microorganisms existing in the soil, and the low boiling point organochlorine compounds are vaporized. !
