退役炼油厂粉砂质土壤气相抽提的影响半径及因素研究

Study on the Influence Radius and Factors of Gas-Phase Extraction of Silty Soil in Retired Refineries

利用项目中试数据,分析环境温度、土壤含水率和抽提负压对气相抽提效果的影响。研究结果表明,粉砂质土壤区域最大影响半径约为6 m;环境温度、土壤含水率和抽提负压对气相抽提效果均有明显影响。

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.
