<p><P>PROBLEM TO BE SOLVED: To provide a method for decontaminating polluted soil by which polluted soil, or the like, can be decontaminated by making the most of a microorganism as it is without cultivation while utilizing a decontamination function of the microorganism, the polluted soil can be decontaminated at its original position without making it into a slurry shape, or the like, since a catalyst can be activated by work of a catalyst activating auxiliary agent, further decontamination spacing of the polluted soil can be secured by digging the polluted soil, for example, the polluted soil can be decontaminated on-site and in a gentle temperature condition, moreover treating time is shortened and environmental burden can be mitigated. <P>SOLUTION: Decontamination method for soil, or the like having a process for blending the soil, or the like, containing organic pollutants with compost and a process for making the soil into an anaerobic condition in a water condition, a decontamination method for soil, or the like, in which soil, or the like, containing dioxins is blended with a reducing agent and is made into the water condition, a decontamination method for soil, or the like, in which acetic acid is added to the soil, or the like, containing the organic pollutants to make slurry and then hydrogen peroxide is added thereto, a decontamination method for the polluted soil in which a catalyst activating auxiliary agent and hydrogen peroxide are added to the soil polluted with dioxins, and a decontamination method for the polluted soil in which one kind or two or more kinds of periodic metal compounds are added to the soil polluted with dioxins, and are mixed by agitation, the catalyst activating auxiliary agent and then hydrogen peroxide are further added thereto, are provided. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
