多环芳烃污染土壤的可行处理技术

Workable Technologies for Treating PAH-Contaminated Soil

本文讨论了处理多环芳烃(PAHs)污染土壤的可行技术。土壤冲洗可解决部分问题;土壤焚烧可高效地去除PAHs,但是通常这种方法会导致二次污染;含PAHs土壤的生物处理得到了广泛的关注,因为生物处理没有副产品,可以在没有副作用的情况下消除污染物。PAHs的土壤污染问题远没有解决,然而,生物处理已经给我们提供了解决问题的希望。

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 bum 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.
