Description
Technical Field
The invention belongs to the technical field of ecological restoration, and particularly relates to a soil ecological restoration device.
Background
With the development of the petroleum industry, the pollution of volatile organic compounds (VOCs and) and semi-volatile organic compounds (SVOCs) such as gasoline and diesel oil in the soil environment is increasing. They are mainly caused by oil spillage accidents, such as breakage of oil pipelines, leakage from storage tanks, and leakage problems from underground oil storage tanks. In addition, with the development of chemical industry, the pollution of various VOCs such as benzene, toluene, carbon tetrachloride and the like to soil is also increasing, such as random dumping of chemical wastes and chemical agents, leakage of chemical plants, accidents in chemical transportation and the like. These contaminants can create a number of environmental problems: the physical and chemical properties of the soil are affected; threatens the water quality safety of the underground water source; air pollution; the risk of explosion due to accumulation of hydrocarbon gases in the basement of buildings; leaking hydrocarbon compounds accelerates the aging of utility grid facilities in contact therewith, and the like. At present, the off-site treatment of VOCs and SVOCs polluted soil is to dig out the polluted soil and then carry out subsequent treatment, and the used methods comprise landfill, incineration, hydraulic flushing and biological treatment. However, these methods have their own disadvantages: landfill is simple to treat, but expensive, and may face secondary treatment; although the incineration treatment effect is good, the treatment equipment is complex and expensive, and secondary pollution can be generated; the waste of hydraulic flushing is serious, the treatment effect is not ideal, and flushing water needs to be treated; the biological treatment period is long, the treatment effect is not ideal, and secondary pollution can be generated. Zhang Mi et al published "numerical simulation of method for removing volatile contaminants by air extraction" in the soil contaminated by volatile contaminants "in" rock and soil mechanics "volume 25, 4 months 2004, P544 to 545, wherein a part of the contaminants exist in a gaseous state and the rest exist in pores of soil in a liquid, dissolved or adsorbed state, under normal conditions, the contaminants at different phases are in a dynamic equilibrium state, and when a vacuum well is disposed in the soil and removed by air extraction with an air extraction pump, a vacuum is formed in the vacuum well and surrounding soil to generate a pressure gradient, soil gas containing gaseous contaminants is driven to flow in the direction of the vacuum well for air extraction, and the air flow is processed and discharged to the atmosphere after being extracted to the ground. However, this is only an established mathematical model, and therefore, the development of an economical and effective technology for the off-site treatment of the VOCs and SVOCs contaminated soil becomes a problem to be solved urgently. After searching, no relevant published patent is found.
In order to solve the problems, the Chinese patent 'volatile and semi-volatile organic compound polluted soil field treatment process and device' (patent number: 200410056888.7) discloses a volatile and semi-volatile organic compound polluted soil field treatment process and device, which accelerates the volatilization of pollutants by heating the soil and has the advantages of simple structure and the like; however, the device of the patent has the following defects: (1) the soil needs to be heated, so that the treatment cost is increased; (2) volatile and semi-volatile organic compounds are only adsorbed by activated carbon and are difficult to reach the emission standard of atmosphere; (3) the process has simple structure and poor adaptability, is only used for treating the soil polluted by volatile and semi-volatile organic compounds, and cannot relate to the effective treatment of other polluted soil.
