<p>PROBLEM TO BE SOLVED: To provide a method for purifying a pollutant-containing medium that can increase the soil treatment amount per hour by performing removal and microbial decomposition in parallel to reduce a treatment time of polluted soil, and can make a decomposition treatment apparatus compact while reducing the whole treatment time.SOLUTION: A method for purifying a pollutant-containing medium includes: a step A of preparing a nutrient source for microorganisms and an eluent for pollutants and injecting them into the ground, which is a polluted medium, from a cleaning liquid preparation tank 1 through an injection well 2; a step B of eluting and recovering pollutants from the medium to a pollutant recovery device 5 by a pump 4 through a recovery well 3; and a step C of decomposing the pollutants by microorganisms. The process B and C are performed in parallel.</p> |
