Abstract
A large amount of petroleum hydrocarbon pollutants will be produced during the oilfield exploitation process. If traditional treatment methods of physical or chemical methods are used, problems such as incomplete treatment and secondary pollution will occur. In order to achieve better treatment effects, the microbial degradation method is currently used to treat petroleum hydrocarbon pollutants. Studying the mechanism of microbial degradation of petroleum hydrocarbon pollutants is conducive to exploring the path of petroleum pollution remediation technology and improving the efficiency of pollution control. In this review, the degradation mechanism of alkanes, alkenes and aromatics is discussed in detail, and the research directions of microbial pollution control are analyzed and discussed.
