Abstract

The invention discloses a restoration method for petroleum hydrocarbon polluted soil. The restoration method comprises the following steps: inspecting and determining a range of petroleum hydrocarbonpolluted soil; analyzing pollution characteristics of the petroleum hydrocarbon polluted soil, and performing the plant-microorganism joint effect restoration for the petroleum hydrocarbon polluted soil according to the pollution characteristic analysis result. The restoration method for petroleum hydrocarbon polluted soil provided by the invention is characterized in that the petroleum hydrocarbon pollutants can be permanently degraded by utilizing the joint degradation effect of the microorganisms and plants, the secondary migration of the petroleum hydrocarbon pollutants along with the soilcan be prevented and controlled, the form morphological transformation of the pollutants and the secondary pollution of the pollutants for the peripheral environment can be controlled, the pollutionrestoration cost can be reduced, the pollution restoration effect and restoration efficiency can be improved, the process is simple, and the material is universal.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to a method for remediating petroleum hydrocarbon-contaminated soil. Background technique [0002] Soil is one of the important components of the ecological environment and one of the material basis and main resources for human survival. my country is a big agricultural country, and soil is a particularly important natural resource for our country. But in recent years, due to the rapid development of the petroleum industry, in the process of petroleum production, storage and transportation, refining and processing, due to accidents or abnormal operation and maintenance, there will be spillage or discharge of petroleum hydrocarbon substances, resulting in increasingly serious pollution. [0003] After petroleum pollutants enter the soil, due to their special physical and chemical properties, difficulty in removal and long residual time, they will cause a serie...
