摘　　要：通过室内模拟,研究了采用不同激活剂激活石油污染土壤中的土著微生物对石油烃污染土壤的修复效果.结果表明,激活剂为硫酸铵浓度:40.99 g/kg,KH2PO4浓度:4.73 g/kg时,土著微生物对土壤中石油烃经30 d的修复,降解率达86.27%,激活后土壤中降解石油烃的微生物量由初始的4.78×105cell/g增加到5.71×106 cell/g.The remediation efficiency of petroleum hydrocarbons contaminated soil by stimulating indigenous reagents was investigated by indoor simulation. The results indicate that the optimal stimulating reagents were （NH4）2SO4 40.99 g/kg and KH2PO4 4. 713 g/kg, by which the biodegradation efficiency of petroleum hydrocarbons reached 86.27% after a 30d-remediation. Meanwhile,the indigenous microbes increase from original 4.78×10^5cell/g to 5.71 × 10^6cell/g after stimulation.
