摘要
根据多环芳烃(PAHs)污染土壤修复技术的现状及研究进展,总结了各种修复技术的优缺点及应用范围,并列举了水力压裂技术应用于低渗有机物污染场地修复的工程案例。通过人为构建裂缝网络,有效提升土壤渗透性,可以较好地解决化学药剂在低渗场地中的传质扩散难题。
According to the current situation and research progress of polycyclic aromatic hydrocarbons(PAHs)contaminated soil remediation technology,the merits and demerits and application scope of various remediation technologies were summarized,and the engineering cases of hydraulic fracturing technology applied to the remediation of low permeability organic contaminated sites were listed.The soil permeability is effectively improved by artificially constructing a fracture network,so as to better solve the problem of mass transfer and diffusion of chemical agents in low permeability sites.
