Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a soil treatment equipment which promotes the vaporization and suction of a recovery well not by separately providing the equipment with a compressor like heretofore but circulating the air cleaned through an active carbon adsorption treating device to a vent well and discharging the same into the soil. SOLUTION: The contaminants in the soil are sucked while the vaporization of the recovery well 1 is promoted by connecting a vent pipe 11 to the vent well 10 consisting of a perforated pipe 9 embedded near the recovery well 1, installing a vacuum pump as a suction machine 6 thereto, connecting an air exit 6b of the vacuum pump 6 and the vent pipe 11 of the vent well by a pipeline 12 and discharging the air cleaned by passing of the air in the soil sucked from the recovery well 1 by the vacuum pump 6 through the active carbon adsorption treating device 5 into the soil from the vent well 10.
