多环芳烃污染土壤修复技术研究进展

Research Progress on Remediation Technology of PAHs Contaminated Soil

随着我国工业化和经济发展水平不断提高,土壤中多环芳烃污染日益严重。针对多环芳烃污染土壤的治理与修复,首先介绍了目前多环芳烃污染土壤的3种修复模式,其次对多环芳烃污染土壤各种修复技术原理、研究进展及优缺点进行了梳理和分析,最后提出了在选择修复技术时需综合考虑多环芳烃浓度、场地水文地质条件、修复工期、修复目标、未来土地规划及利用类型等多种要素,以期为我国多环芳烃污染土壤修复提供借鉴,实现良好的经济效益与社会效益。

With the continuous improvement of industrialization and economic development in our country,the pollution of PAHs in soil is becoming increasingly serious.In view of the treatment and remediation of PAHs contaminated soil,this paper first introduced three current remediation modes of PAHs contaminated soil at present,and then sorted out and analyzed the principles,research progress,advantages and disadvantages of various remediation technologies.Finally,it was suggested that the concentration of PAHs,site hydrogeological conditions,restoration period,restoration target,future land planning and utilization types should be comprehensively considered in the selection of remediation technology,so as to provide references for the remediation of PAHs contaminated soil in China to achieve good economic and social benefits.
