摘　　要：为了探究生物修复技术对油污土壤的处理效果,研究采用生物刺激和生物强化修复技术研究在修复过程中石油烃组分含量、表面张力、微生物数量、酶活性指标的变化。结果表明:生物刺激在降解饱和烃、降低土壤中溶液表面张力、增加微生物数量、提高土壤酶活性方面优于生物强化,而生物强化则对于石油烃中难降解的芳香烃有很好的降解效果,两者各有优势。In order to explore the effect of bio-remedying petroleum-contaminated soil,the biological stimulation and biological enhancement technologies were employed to study the changes of petroleum hydrocarbon component,surface tension,the quantity of microorganism,and enzyme activity index in the remediation process. The results showed that biological stimulation was better than biological enhancement in the degradation of saturated hydrocarbon,the reduction of the surface tension,increasing the quantity of microorganism,and the improving enzyme activity;while biological enhancement degraded refractory aromatic hydrocarbon better than biological stimulation,each of them had its own advantages.
