We have compared the influence of petroleum degradation efficiency which natives microorganism and inoculating the mud of greasy in factory have reached through single factor experiment (petroleum density is 1%) as well as inoculating the mud of greasy and different petroleum density (petroleum density is 1% andti5%); through orthogonality test, choosing nutrition material, water content, electron receiver and surface activator as controlling factors, we have reached the best ecological condition of biological degradation; finally in the process of petroleum bioremediation under the best ecological condition, discussed the degradation condition of alkyl hydrocarbon and aromatic hydrocarbon.
通过单因素试验比较了土著微生物和接种石化厂内含油污泥后的土壤（石油浓度均为1％）以及在接种含油污泥后不同石油浓度（1％和5％）对石油降解效率的影响；通过正交试验，以营养物质、含水量、电子受体和表面活性剂为因素得出了最佳的生物降解生态条件；最后在最佳生态条件下对石油修复过程中的烷烃和芳香烃的降解情况进行了探讨。
