Description

technical field

[0001] The invention relates to a device for purifying and treating pollutants, in particular to a two-dimensional non-uniform electric field experimental device for electrically repairing polluted soil, belonging to the fields of environmental protection and pollution prevention and control. Background technique

[0002] With the continuation of my country's industrialization process and the large-dose, large-scale, and long-term use of pesticides in agricultural production, relatively serious soil pollution has accumulated, for example, in heavily polluted enterprises or industrial-intensive areas, industrial and mining areas and surrounding areas Areas with heavy soil pollution and high-risk areas have emerged in regional, urban and suburban areas. At the same time, the types of soil pollution are also showing a trend of diversification and complexity. For example, in many areas, new and old pollutants coexist, and inorganic-organic compound pollution is se...
