As the population is rapidly increased and the industry is rapidly developed, solid wastes are continuously stacked and dumped on the surface of soil, harmful waste water continuously permeates into the soil, and harmful gas and floating dust in the atmosphere continuously fall into the soil along with rainwater, so that the soil pollution is caused. Soil pollutants can be broadly classified into two broad categories, inorganic pollutants and organic pollutants. The inorganic pollutants mainly comprise acid, alkali, heavy metal, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, and the like. The organic pollutants mainly comprise organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3, 4-benzopyrene, harmful microorganisms brought by municipal sewage, sludge and animal manure, and the like. When the soil contains excessive harmful substances and exceeds the self-cleaning capacity of the soil, the composition, the structure and the function of the soil are changed, the microbial activity is inhibited, and the harmful substances or decomposition products thereof are gradually accumulated in the soil and are indirectly absorbed by the human body through the soil → plants → the human body, so that the degree of harming the health of the human body is reached. Soil remediation is a technical measure to restore normal function to contaminated soil. In the soil remediation industry, the existing soil remediation technologies can be more than one hundred, the common technologies can be more than ten, and the existing soil remediation technologies can be roughly divided into three methods, namely physical methods, chemical methods and biological methods.
