IN SITU DECONTAMINATION SYSTEM OF CONTAMINATED GROUND WATER

摘要

PROBLEM TO BE SOLVED: To provide a in situ decontamination system of contaminated ground water that is capable of effecting the uniform and rapid decontamination, and economically and effectively conducting the decontamination of the contaminated substance in situ by promoting the circulation of the ground water, the vaporization and diffusion of the contaminated substance and the activation of microorganic decomposition notwithstanding the situation of foundation by means of the decontamination equipment using the pumping water circulation method in combination with the sparging method of simple installations.

SOLUTION: The in situ decontamination system 1 of the contaminated ground water is provided with a sparging well 10 for forcing air A and liquid W into soil and a pumping well 40 for pumping the contaminated ground water. The system forces the air A into the soil from the sparging well 10 and simultaneously forces the liquid W into the soil, and pumps the contaminated ground water from the pumping well.
