多环芳烃污染土壤修复技术研究进展OA

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.
