摘　　要：基于我国土壤氯代烃污染现状及应用生物炭材料修复的局限性,针对生物炭性能受官能团、吸附位点数量限制和实际场地修复应用的长效性较差等问题,系统综述了生物炭不同改性方法及其对生物炭性能的改进,分析了生物炭基改性材料作为载体固定化降解微生物菌剂的特性,并深入阐述酸碱改性、金属改性生物炭及生物炭基材料固定化微生物去除氯代烃的机理与效能,以期为生物炭作为土壤氯代烃污染修复材料提供新思路。This research is carried out by the current status of soil chlorinated hydrocarbon pollution in China and the limitations of applying biochar for soil remediation.In light of the practical problems that the properties of biochar are limited by functional groups,the number of adsorption sites and the long-term efficacy in the practical remediation application is poor,this paper systematically reviews the different modification methods and how these methods enhance properties of biochar.The characteristics of biochar-based materials immobilized microorganisms have been analyzed.Furthermore,in order to provide new thoughts for biochar as a remediation material into soil chlorinated hydrocarbons contamination,a detailed investigation into the mechanism and efficiency of acid-alkali modified biochar,metals modified biochar and biochar-based materials immobilized microorganisms on the removal of chlorinated hydrocarbons has been provided.
