| titleOfInvention | Decomposition method of chlorethylene in soil and groundwater |
| abstract | PROBLEM TO BE SOLVED: To use a low-priced iron reductant for soil and groundwater contaminated with chlorethylene, and soil and / or groundwater in which chlorethylene is by-produced by decomposition of organic chlorine compounds such as trichloroethylene in the soil and groundwater Provide a method of decomposing chloroethylene in a short period of time and decomposing chloroethylene in a short period of time and purifying soil and groundwater. SOLUTION: A copper-containing iron powder is dispersed in a soil contaminated with chloroethylene and having a water content of 5% by mass or more and / or in groundwater contaminated with chloroethylene to lay an iron powder dispersion layer, and the above-mentioned iron A decomposition treatment method of chloroethylene which decomposes the chloroethylene in the powder dispersion layer. A method of decomposing and treating chloroethylene in soil and / or groundwater using iron powder containing 0.1 to 20% by mass of copper. A decomposition treatment method of chloroethylene, in which 0.1 to 10% by mass of the copper-containing iron powder is dispersed in the soil and / or underground water. [Selected figure] Figure 13 |
