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

土壤污染是指某些元素超標導(dǎo)致土壤效力下降,影響農(nóng)作物生產(chǎn)和人民群眾的正常生活[1],污染土壤修復(fù)已成為亟待解決的問題。(剩余3527字)
