Background
The economic development is fast since the innovation, the material civilization and the mental civilization are continuously enriched, the living standard of people is obviously improved, and the comprehensive national force is greatly enhanced. However, with the development of large-scale industrialization, urbanization and agricultural intensification in a short period, the environmental pollution problem in China is increasingly prominent, the pollution events of atmosphere, water, soil and noise frequently occur, the environmental disasters are reported, and the environmental pollution becomes a bottleneck problem restricting the economic development of China.
The soil is a material foundation for sustainable development of the economy and the society. At present, the soil environment condition of China is not optimistic overall, and according to the survey bulletin of national soil pollution conditions (4 months and 17 days 2014), the total exceeding rate of the national soil is 16.1%, wherein the proportion of slightly, moderately and severely polluted points is 11.2%, 2.3%, 1.5% and 1.1% respectively. The quality of the soil environment of the cultivated land is great, the exceeding rate of the soil point position is 19.4 percent, wherein the proportion of the slight, moderate and severe polluted point positions is respectively 13.7 percent, 2.8 percent, 1.8 percent and 1.1 percent, and the main pollutants are cadmium, nickel, copper, arsenic, mercury, lead, dichlorodiphenyl trichloroethane and polycyclic aromatic hydrocarbon. Chemical pollutants enter water and soil in various ways and cause direct or potential harm to human health and ecological environment, wherein the environmental pollution is the most serious by heavy metal ions (chromium, cadmium, copper, mercury, nickel, zinc and the like) generated in the industrial production processes of mining and metallurgy, mechanical manufacturing, chemical industry, electronics, instruments and the like. Heavy metal ions have high toxicity, are not degraded in the environment, are not easy to convert, not only pollute soil, surface water and underground water, but also cause harm to human health through a food chain along with accumulation of organisms.
At present, methods for treating soil heavy metal ion pollutants mainly comprise an ion exchange method, a complex method, an incineration method, a soil replacement method, an electrodynamics method, an adsorption method and the like. The electric soil remediation method has the advantages of low cost, wide application, high speed, less secondary pollution and the like, is suitable for low-permeability soil, can remove heavy metals such as copper, zinc, lead, cadmium, nickel, arsenic, mercury, manganese and the like in the soil, and can also remove organic matters such as phenol, p-nitrophenol, hexachlorobutadiene and the like. The electric soil remediation method has technical bottlenecks of acid zone migration, soil pH control, polarization and the like in the application process, wherein the polarization problem is particularly prominent. The polarization phenomenon is mainly caused by that cations and anions are distributed and concentrated near the electrodes under the driving of an electric field. The effective utilization rate of the electric field is low, and the practical application of the electric field is influenced. The deposition of a large amount of heavy metal ions at the cathode is difficult to operate stably and continuously for a long time, and the efficiency is low. In order to overcome this phenomenon, researchers have proposed polarity exchange technology, approaching anode technology and buffer solution injection technology, and though improvements are made, no breakthrough progress is made.
