Abstract: Using project pilot data, the effects of environmental temperature, soil moisture content, and extraction negative pressure on gas-phase extraction efficiency are analyzed. The research results indicate that the maximum impact radius of the sandy soil area is about 6 m; the environmental temperature, soil moisture content, and extraction negative pressure all have a significant impact on the gas-phase extraction efficiency.
Keywords: gas-phase extraction technology; influence radius; environmental temperature; soil moisture content; extraction negative pressure
