WALL FOR PREVENTING DIFFUSION OF VOLATILE ORGANIC COMPOUND, METHOD FOR CONSTRUCTING WALL, AND METHOD FOR PURIFYING VOLATILE ORGANIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To purify volatile organic compounds polluting ground water and soil.

SOLUTION: In a method for purifying the volatile organic compounds, the polluted region 3 in the ground 2 polluted with the volatile organic compounds is agitated/mixed with active carbon powder 32. Nutrition sources for soil bacteria decomposing the organic compounds are adsorbed in advance on the active carbon powder 32. In order to agitate/mix the polluted region 3 with the active carbon powder 32, for example, a DJM method can be used. The region 3 polluted with the organic compounds and the active carbon powder 32 are agitated/mixed by an agitation blade 4, and the organic compounds contained in the region 3 are adsorbed on the active carbon powder 32. It is assumed that the region 3 in the ground 2 is located to be equal to or above the level of the ground water or to be equal or below the level of the ground water.
