摘要
近年来,土壤复合污染问题日益凸显并引起了人们的广泛关注。生物淋滤技术已在去除土壤、污泥等介质中重金属污染方面得到了较多应用,并取得了良好效果。电动修复技术与生物淋滤技术联用不仅具备各自优势,还能一定程度上互补劣势,降低电动修复能耗的同时缩短生物淋滤时间。该文综述了生物炭等功能材料用于改良生物淋滤和电动修复引起的土壤酸化问题的研究进展,为修复后土壤的资源化利用提供基础资料。
Co-contamination of soil has aroused a wide attention.As an environmental friendly and cost-effectivelyheavy metal remediation technology,bioleaching has been widely used in the extraction of heavy metals in contami-nated soil and sediment.The combination of electrokinetic technology and bioleaching in the remediation of co-con-taminated soil has complementary advantages.In addition,the bioleaching progress has been accelerated with lesspower consumption.For further utilization,biochar has been used to ameliorate the soil acidification problem causedby remediation.
