空气震裂与双相真空抽吸联动修复技术应用

Ganged Repair Technology Application of Pneumatic Fracturing and Dual-phase Vacuum Suction

文章介绍了空气震裂与双相真空抽吸联动原位修复技术的原理,并将该技术应用于土壤和地下水污染现场修复试验。试验数据表明:空气震裂技术有利于提高污染物质的传输性,与双相真空抽吸技术联动运行可有效提高现场自由相污染物的去除率。空气震裂与双相真空抽吸联动运行系统修复的场地试验结果表明:在12d内自由相污染物的平均去除率为86.68%。

This article introduces the theory of pneumatic fracturing and dual-phase vacuum in-situ remediation technology and applies it to remediation test on polluted soil and underground water site.Experimental data shows that pneumatic fracturing technology contributes to improving the transportability of pollutants and effectively raises removal rates of on-site free-phase contaminants when ganged with dual-phase vacuum technology. The field experiment results of ganged pneumatic fracturing and dual-phase vacuum system remediation show that the average removal rate of free-phase contaminants in 12dis 86.68%.
