1) Petroleum composition is often very complex, and this complexity is often interwoven with the complexity of structural components of contaminated soil, resulting in the complexity of pollution characteristics and consequences. A kind of

2) Because of the continuity of the soil surface, oil often fills almost all the voids in the soil with a certain area and a certain depth, blocking the vast majority of soil pores.

3) Due to the viscosity of oil, the oil in the soil will be scattered soil particles, glue together, change the original structural characteristics of the soil, is not conducive to the growth and reproduction of soil microorganisms, is not conducive to the growth of soil roots in the soil and the absorption and transportation of soil organic matter, which aggravates the soil pollution.

There are four kinds of surfactants: physical methods, chemical methods, bioremediation methods and comprehensive remediation methods. A kind of

1. Physical methods mainly include cleaning method of contaminated soil, soil leaching method, heating decomposition absorption method and soil vapor phase suction method. A kind of

1) Soil cleaning: the remediation effect is good. A kind of

Process flow: excavation of contaminated soil, cleaning of contaminated soil
