46 6 restoration technical route was determined economically. It provided expe-
riences and technical reference for similar projects in China. The pollution degree of the contaminated soil in the plot was divided
by the pollution index method. Chemical oxidation technology had a good remediation effect on moderately and mildly PAHs con-
taminated soil. However, it was uncertainty in achieving the remediation target for severely polluted soil. For contaminated site
having PAHs with different degrees, the combination of chemical oxidation technology and cement kiln collaborative treatment
technology was more economical.
Key words
:contaminated soil; PAHs; oxidation; restoring
