摘要: 电动-电动-可渗透反应墙(EKR-PRB)耦合技术,结合了电动修复(electrokinetic remediation,EKR)和渗透反应墙(permeable reactive barrier,PRB)两者的优点,是近年来新兴的一类原位污染场地修复技术,在污染场地土壤和地下水修复中有着良好的应用前景。针对该技术的修复原理、影响因素、应用优势和存在的问题进行了综述和探讨,并就未来进一步提高EKR-PRB修复效率和降低应用成本的相关研究提出了展望。可渗透反应墙(EKR-PRB)耦合技术,结合了电动修复(electrokinetic remediation,EKR)和渗透反应墙(permeable reactive barrier,PRB)两者的优点,是近年来新兴的一类原位污染场地修复技术,在污染场地土壤和地下水修复中有着良好的应用前景。针对该技术的修复原理、影响因素、应用优势和存在的问题进行了综述和探讨,并就未来进一步提高EKR-PRB修复效率和降低应用成本的相关研究提出了展望。Abstract: EKR-PRB coupling technique combines electrokinetic remediation ( EKR) and permeable reactive barrier ( PRB) technology． As a novel in-situ remediation technology for contaminated site， it has a good application prospect in the soil and groundwater remediation． The mechanisms，influence factors，application advantages and the existing problems of EKR-PRB coupling technique were summarized，and further suggestions were given out on potential improvement of higher remediation efficiency and lower practice cost in contaminated site．
