The present invention provides an efficient simultaneous purification means for contaminated soil and groundwater. In purifying contaminated soil and groundwater, a soil gas is sucked from a well by a blower, and the air containing the sucked soil gas is liquid-separated as required, and then a gaseous pollutant detoxification treatment tank. At the same time as the above treatment, the contaminated groundwater is pumped from the well and the pumped groundwater is aerated with the clean air discharged from the pollutant detoxification treatment tank. The pollutant inside is vaporized and the vaporized pollutant is supplied to the pollutant detoxification treatment tank to detoxify the pollutant. [Selection] Figure 2 |
