通过一种可变换阵列式电极的电动-可渗透反应墙（EK-PRB）装置，以沸石+粉煤灰组合为PRB材料，研究了电压梯度和土壤含水率在EK-PRB修复Pb（II）污染土壤的过程中对于去除效果的影响。试验过程中，修复周期定为5 d，设置了不同的电压梯度（1.5，2.0，2.5 V/cm）和含水率（25%，30%，35%），进行了9组正交试验。结果表明，提高电压梯度、增大含水率对于Pb（II）去除效果均具有增强作用，由此得出了以沸石+粉煤灰作为PRB材料时，EK-PRB修复Pb（II）污染土壤的含水率和电压梯度最佳组合，即在电压梯度和含水率分别为2.5 V/cm和35%时，Pb（II）的修复效果最好，去除率最高达到了80.7%。证明了沸石和粉煤灰作为组合材料时，EK-PRB联合修复技术在处理Pb（II）污染高岭土时的可行性，可以为EK-PRB在PRB材料的改性和创新上的发展提供支持和依据。“,”By virtue of a device of electrokinetic (EK) with permeable reactive barrier (PRB) with swithchable array electrodes, the influences of voltage gradient and water content on the removing effects were studied when using a kind of soil heavy metal repairing device to remediate Pb(II)-contaminated kaolin, and using the combination of zeolite and fly ash as filling material. The repair period was set as 5 d. Different voltage gradients (1.5, 2.0, 2.5 V/cm) and water content (25%, 30%, 35%) were set and 9 orthogonal tests were conducted. The results show that both enhancing the voltage gradient and increasing water content have enhancement effect on removing Pb(II). It is concluded that when zeolite + fly ash is used as the PRB material, the optimal combination of water content and voltage gradient, in the EK-PRB remediation of Pb (II) contaminated soil is 2.5 V/cm and 35%. The removal rate reaches 80.7%. The feasibility of EK-PRB combined repair technology in the treatment of Pb(II) contaminated kaolin was proved when zeolite and fly ash were used as a composite material. The results provide the support and basis for the development of EK-PRB in the modification and innovation of PRB materials.
