【摘要】 概述了石油生物降解速率的主要影响因素：烃类的组成与状态、烃类降解微生物、温度与ｐＨ值、Ｏ２和营养。介绍了土壤和地下水石油污染的两种生物治理方法：菌种法和营养物法，认为该法具有安全、经济、高效、无二次污染、不需大型设备、操作简单等优点，但也具有一定的局限性。更多还原

【Abstract】 The factors determining rates of petroleum biodegradation includes the composition and physical state of petroleum hydrocarbons,the microbial community,etmperature and pH value,O 2,nutrition and so on.There are two methods of microbial degradation adding nutritents and seeding microorgnisms.The biological technique is safe,economical,efficient and sanitary,but limited in a certain sense.更多还原
