Oil-soiled soils are mainly produced in the process of oil extraction, transportation, and refining. Oil will hinder the absorption of nutrients and moisture by plant roots and affect the permeability of soils, and toxic and harmful substances such as polycyclic aromatic hydrocarbons will be gradually enriched in plant bodies. , endanger human health. Therefore, the search for oil-soil treatment technology is an inevitable requirement for the secondary use of resources and sustainable development of the ecological environment. In response to petroleum-contaminated soils, the Key Laboratory of Low-Carbon Conversion Science and Engineering, Shanghai Institute of Advanced Study, Chinese Academy of Sciences developed a new and fast oil-soil treatment technology. The selective heating of the oil heating process through directed energy supply significantly reduces the traditional thermal desorption temperature and achieves efficient and rapid oil product removal from oil-soiled soils under mild conditions. The oil recovery rate exceeds 95% and lighter steam is achieved. High-efficiency separation of diesel and heavy residue fractions, and the fraction of diesel oil recovered in the recovered oil reaches 60%. The soil after low-temperature heat treatment can maintain the original nutrient composition and texture characteristics, and the soil organic carbon content is about 6%. Plant pot experiment shows that the soil can meet its normal growth needs. This technology is suitable for the treatment of oily soils with various concentrations and involatiles. At the same time when oil products are recovered, the harmlessness of oil-polluted soils and crop rehabilitation are realized, providing a new solution to the repair of oil-soiled soil and the recovery and utilization of oil products. . The relevant research results have already been applied for national invention patents (a method and device for rapid microwave repair and oil recovery of petroleum contaminated soils, application number 201610044637.X).
