摘　　要：用常规的堆肥法和在堆肥中接入降解菌(包括自行培养、筛选的混合菌和引入的白腐真菌)的方法处理受多环芳烃污染的土壤,找出了最适合的堆制条件,研究了4～6环的多环芳烃在堆制不同阶段的降解规律。结果表明,堆制法对几种难降解的多环芳烃都有不同程度的降解作用,在堆肥中接入降解菌后降解效果明显提高,其中白腐真菌的降解效果最好。The polluted soil by polycyclic aromatic hydrocarbons(PAHs)was treated with normal composting and inoculating the degrading microorganisms into the compost.A suit- able condition for composting was obtained searched,the degradation of 4～6 cyclic PAHs in some steps of composting was monitored o The result indicated that all of the PAHs had de- grated to some extent in the soil composting system,and white rot fungi was the most effi- cient for degrading PAHs.
