Workable technologies available for treating PAHs contaminated soils are discussed in this paper. Soil washing can partly solve the problem and soil incineration can efficiency burn out PAHs, but both of the two methods may result in secondary pollution. Lots of efforts have been devoted to biological treatment of PAHs contaminated soil. This is because biological treatment has no by-product and can eliminate the contaminants without any side effect. It has been concluded that the problem of PAHs contaminated soil is far from having been completely solved. However, biological treatment has brought us some hope for solution of the problem.
