多环芳烃(PAHs)是一类重毒污染物,其污染土壤对人类的健康造成了严重危害,所以对污染土壤进行修复势在必行.首先讨论了处理多环芳烃(PAHs)污染土壤的多种可行技术；然后详细介绍了回转窑高温热解析在北京某焦化厂多环芳烃污染土壤修复中的应用及效果,研究发现回转窑高温热解析技术不仅能有效去除污染土中的有机污染物,而且还能抑制二噁英等剧毒物的产生.%Polycyclic aromatic hydrocarbons (PAHs) is a kind of heavy virus pollutants. Soil polluted with PAHs has serious harm to humanity's health, therefore it is imperative to repair this kind of soil. Workable technologies available for treating PAHs contaminated soils are discussed in the first part, then the rotary kiln high temperature thermal decomposition( HTTD) technology using in treating PAHs contaminated soils is discussed in details. The results show that HTTD can not only remove PAHs pollutants from soil but also do not reduce dioxin.
