Study on Microbial Remediation of Petroleum Contaminated Soil

Petroleum contaminated soil is an urgent problem to be solved in the protection of soil ecological environment. How to effectively remediate contaminated soil has become a research hotspot. Microbial remediation technology is a kind of economical, efficient and ecological green cleaning technology to deal with petroleum contaminated soil. Under this background, the influencing factors of microbial remediation of petroleum contaminated soil were analyzed. In the process of composting remediation of petroleum contaminated soil, measures such as adding petroleum degrading bacteria, oxidant, nutrient substance and surfactant were introduced to enhance the remediation effect of petroleum contaminated soil. Finally, the development directions of microbial remediation technology of petroleum contaminated soil were discussed for providing a reference for further research.
