摘要： PROBLEM TO BE SOLVED: To provide a measuring method for precisely grasping lowering in the concentration of a contaminant. SOLUTION: In the measuring method for the concentration of the contaminant, soil treated with a microorganism is used as a sample 1 as shown in Fig. (a), and the sample is put inside a container 3. As shown in Fig. (b), acid water or alkaline water is put into the container 3, and a mixed solution 5 is prepared together with the sample 1. The opening of the container 3 is plugged up by using a stopper body 6, the container 3 is shaken in this state as shown in Fig. (c), and the mixed solution 5 inside the container is stirred. After it has been set left standing for a prescribed time, the concentration of trichlorethylene 7, volatilized and diffused to an air space inside the container 3 as shown in Fig. (d), is analyzed by using a portable type gas chromatograph.

摘要： PROBLEM TO BE SOLVED: To efficiently clean a contaminated substance without imparting an influence to the environment and carrying out a after-treatment such as pH adjustment for preventing it even in the contaminated soil having high viscosity. SOLUTION: In the method for cleaning contaminated soil by a microorganism, the contaminated soil containing clay or silt as a main component and trichloroethylene as a contaminant is digged and is temporarily placed on a ground (Step 101). Subsequently, a pearlite 2 being one of an inorganic soil improving material, i.e., an oil improving material and a decomposing bacterium 3 for decomposing trichloroethylene are added to the contaminated soil (Step 102). Nextly, gap water contained in the clay or the silt is absorbed to the pearlite 2 by stirring/mixing the contaminated soil (Step 103). Subsequently, a ventilation work for feeding air into the contaminated soil 1 to decompose trichloroethylene by the microorganism (Step 104). COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a means of cleaning contaminants such as VOC and oil contained in contaminated soil without making a heavy metal elute even in a small-scale plant which can be installed in an excavation site or the vicinity.
SOLUTION: In order to clean the contaminated soil using the method of cleaning the contaminated soil according to the embodiments of the present invention, first quick lime is added to the contaminated soil with contaminants mixed in to form primary treatment soil (Step 101). Next, the primary treatment soil is thrown in a rotary kiln and heated in an airtight state to form secondary treatment soil (Step 102). In the heating process, the contaminants volatilize and the oxidation reaction is carried out within the range of temperatures which can be controlled. Further, the secondary treatment soil after the heat-treatment is discharged from the rotary kiln, and a hardening material such as quick lime is added as needed, and thereafter, it is recycled as general soil(Step 3).
