PURIFICATION METHOD OF CONTAMINATION OF SOIL AND GROUND WATER

摘要

PROBLEM TO BE SOLVED: To provide a method for purifying contamination of soil and ground water at an early stage while suitably controlling an amount of pumping by surrounding the perimeter, installing a pumping well at the proximity of the contaminated portion and conducting the purification of the contaminated substance using activated carbon after pumping the ground water, and which is capable of controlling the inflow rate of ground water from the outside of an impermeable wall.

SOLUTION: The purification method of contamination of soil and ground water is able to conduct the treatment of the contaminated substance in the area surrounded by a plank 2 without leaking or dispersing it to the outside of the plank 2. The method comprises installing the plank 2 constructed by surrounding the soil and sandy soil layer 12 of the contaminated part 1 and a partly opened mouth plank 15 to the plank 2, providing a control apparatus 6 to control the inflow rate of the ground water of the sandy soil layer 12 and installing the pumping well 5 to pump the ground water of the sandy soil layer 12 at the part surrounded by the plank 2.
