The EF-Feox reactor consists of electrodes, a stirring motor, a chemical reagent inlet, a waste water/sediment inlet, a reflux sample inlet and an outlet. The contaminated soil/sediment remediation device is simple in operation and low in cost and has fine remediation effect to contaminated soil/sediment and wide applicable prospect.
Description
Technical field
The present invention relates to a kind of contaminated soil and deposit and get prosthetic device, specifically, is a kind of a kind of contaminated soil-deposit prosthetic device based on EF-Feox technology.
Background technology
Soil pollution has become a ubiquitous problem in the whole world, and has seriously restricted the sustainable development of human society.Soil pollution has not only caused direct economic loss, and causes food quality to descend, and harm humans is healthy, and soil pollution simultaneously also can cause some other secondary ecological environment problem.Present contaminated soil recovery technique mainly contains the following aspects: several big type of physics reparation, chemistry reparation and biological restoration etc.These restorative procedures all exist remediation efficiency not high, cause secondary pollution problems easily, and therefore developing the contaminated soil prosthetic device that a kind of rehabilitation cost is low, simple to operate, repairing effect is good is one of technological difficulties of current contaminated soil reparation.
EF-Feox (anode Fenton) technology is administered the technology that has much potentiality to soil pollution and has been received domestic and international researcher's extensive concern as a kind of, and its basic principle is in soil-liquid phase systems, to insert electrode, passes to direct current.Redox reaction takes place in effect such as electric field, electrochemistry down in the pollutant in the soil, and migration, is enriched in electrode district, thereby reaches the purpose of removal pollutant.
The present invention is directed to the problem that exists in the prior art, is basic principle with the EF-Feox technology, has designed a kind of contaminated soil-deposit prosthetic device.
