| Abstract: |
| Take the typical aged oil contaminated soil as the research object, by analyzing the basic physical and chemical properties of the sample, the basic composition and properties of crude oil and solid phase in oil contaminated soil, a kind of hierarchical combined treatment processing technology is targeted developed. Through detailed process experiments, the optimal process parameters of the combined treatment process are determined. Under optimum technological conditions, the oil content of three layers (dry base) can be reduced to 0.89%, 0.62% and 0.45%, which meets the requirement of environmental protection requirements of oil fields for oil contaminated soil, and provides a good idea for the design of oil contaminated soil treatment process at home and abroad. |
