Dye.And due to the fluctuation of the leaching of rainwater and level of ground water, it can also cause the cross contamination of soil and groundwater.In general,
There is typical pollutant in soil and groundwater：Inorganic matter and organic pollution, including NO3 -、NH4 +, heavy metal Pb, Cr, As
Deng, benzene homologues, petroleum hydrocarbon, Polychlorinated biphenyls, pesticide etc..These pollutants often have high toxicity high carcinogenic, it is therefore necessary to logical
It crosses rational technological means and repairs these contaminated soil and groundwaters.
Soil and groudwater remediation technology mainly has showering and in-situ immobilization at present.Showering is i.e. by contaminated soil
It digs out, transport, repair.This repair mode not only heavy workload, can also cause the secondary pollution of air, it is also possible to because of microorganism
The stench product for acting on and generating impacts nearby residents.Compared with showering technology, in-situ immobilization has protection dirty
Contaminate treatment of the earth, the advantages such as recovery project amount is small, rehabilitation cost is low.In-situ immobilization includes biology in situ reparation, phytoremediation, change
Learn reparation etc..These technologies are generally required in suitable biological agent or chemical agent in-situ injection to soil and groundwater,
So that biology or medicament are sufficiently mixed with the soil body and underground water, to achieve the purpose that reparation.
Traditional injection technique is carried out by the way of injection rod pushing, not only inefficiency, but also is difficult to penetrate sand
The hardpans such as gravel layer, vibrations are strong.There is the improved method for carrying out in-situ injection using hydraulic system later, improves and set
Standby stability and working efficiency.
But required medicament is often the collective effect of two or more medicaments in based technique for in-situ remediation, such as original positionization
Common Fenton reagent in oxidation is learned, consisting of main body medicament H2O2And activator.Fenton reagent injects existing construction technology
It is to be injected in soil and groundwater by injector well after mixing medicament.But the speed that main body medicament is reacted with activator
Very fast, if reinjected after mixing in advance, before being contacted with pollutant, oxidisability has been had a greatly reduced quality, and cannot have been generated well
The hydroxyl radical free radical OH of effect, the effect for repairing pollutant also will be far below being expected.
Therefore, it is necessary to design a kind of injection device in situ, two or more medicaments can be mixed in underground, to reduce medicine
Reacting to each other between agent so that medicament maintains best pharmacological property when being contacted with pollution body, reaches best repair effect.
