Abstract:Based on traditional methods for remediation of petroleum-contaminated soils, the methods, principles, current research status, and applications of combined bioremediation with multiple technologies for remediation of petroleum-contaminated soils were reviewed. How to better combine bioremediation with multi-technology to improve remediation efficiency and remediation products were proposed, which has guiding significance for adopting the multi-technology combined remediation strategy with bioremediation as the core in oilfield pollution control and ecological environment restoration, aiming to provide a basis for improving the remediation effect of oil-contaminated soil.
