Embodiment Construction

[0023] The core component of the polluted soil-sediment remediation device of the present invention is the EF-Feox reactor. The EF-Feox reactor includes a reagent inlet 1, an electrode 2, a stirring motor 3, a wastewater-sediment inlet 4, a reflux inlet 5 and an outlet 6. When the device starts to operate, the polluted soil and waste water are added to the EF-Feox reactor from the waste water-sediment inlet 4, and the treatment agent is added from the agent inlet 1 at the same time, then the power supply and the stirring motor 3 are turned on to start processing, and the outlet 6 is opened after a period of time , A part of the treated soil is discharged, and the other part is returned to the EF-Feox reactor through the reflux inlet 5.

Abstract

The invention discloses a contaminated soil / sediment remediation device, which utilizes an EF-Feox as the technical base and utilizes an EF-Feox reactor as a core component. 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 [0001] The invention relates to a device for remediating polluted soil and deposits, in particular to a device for remediating contaminated soil and deposits based on the EF-Feox process. Background technique [0002] Soil pollution has become a common problem all over the world and seriously restricts the sustainable development of human society. Soil pollution not only causes direct economic losses, but also leads to the decline of food quality and endangers human health. At the same time, soil pollution can also cause some other secondary ecological environmental problems. The current remediation technologies for contaminated soil mainly include the following aspects: physical remediation, chemical remediation, and biological remediation. These remediation methods all have problems such as low remediation efficiency and easy to cause secondary pollution. Therefore, developing a contaminated soil remediation device with low remediation cost, simple operat...
