The prosthetic device of the contaminated soil of the utility model embodiment is applied to using the treatment pollution of sulfate activating technology
Soil, under the activation of the conditions such as heat, light, transition metal, the high activity over cure acid group free radical SO that persulfate can be produced4-
(E=+2.6V), its oxidability is close to hydroxyl radical free radical OH (E=+2.8V) such that it is able to which fast degradation is largely organic
Pollutant.Persulfate can be in stable existence in underground environment for several weeks, and its stability is much larger than O3And H2O2.Additionally, mistake
Influenceed small by pH during sodium sulphate activation degradable organic pollutant, be conducive to being applied to the natural buffered system of weakly acidic pH, relative to
Fenton oxidation method, reduces the acid pollution to soil.It should be noted that the reparation of the contaminated soil of the utility model embodiment
Device is not limited to above-mentioned sulfate activating technology.
Below in conjunction with the accompanying drawings and sulfate activating technology enters to the prosthetic device of the contaminated soil of the utility model embodiment
Row further explanation.When using the present apparatus, it is injected into injector well 6 by by persulfate solution (catalyst), is gone forward side by side
In entering contaminated soil 11, while by high-pressure hot air by air-heater 3 (by structures such as air compressor, firing equipment and air blowers
Into) be transported in injector well 6, persulfate is activated in the presence of high-pressure hot air and produces high activity over cure acid group freedom
Base SO4- (E=+2.6V), its oxidability higher can be by the fast prompt drop of low volatility, persistent organic pollutants in soil
It is volatile small molecule to solve, and sustainable oxidation, it is to avoid soil local excessive is aoxidized.Additionally, high-pressure hot air makes organic contamination
Thing saturated vapour pressure is raised, and is more beneficial for volatilization of the dissolved organic matter in soil；The soil moisture is with high-pressure hot air simultaneously
Injection and raise, the volatile organic matter for contributing to and adsorbing is desorbed in soil.Further, with the extraction well 7
Under the extracting effect of the vavuum pump 4 in the gas extraction device of connection, negative pressure, injector well 6 and extracting are produced in contaminated soil 11
