Soil pollution is serious, pollution type is various, show as the old and new's pollutant and deposit, Inorganic whisker pollution situation, make soil
Reparation becomes one of environmental problem urgently to be resolved hurrily.
Conventional soil remediation method includes soil ablution, biological treatment, electro reclamation etc. at present.Electronic soil
Repairing method has the advantages that low cost, application are wide, speed is fast, secondary pollution is few, it is adaptable to hypotonicity soil, can remove soil
The heavy metals such as copper, zinc, lead, cadmium, nickel, arsenic, mercury, manganese in earth, it is also possible to which removing phenol, p- nitrophenols, hexachlorobutadiene etc. has
Machine thing.There is the technical bottlenecks such as acid band migration, the control of P in soil H, polarization in application process in electronic soil remediation method, its
Middle polarization problem is especially prominent.Polarization phenomena are distributed under electric field driven mainly due to cation and anion and excessively concentrate on
Cause near electrode.In order to overcome this phenomenon, researcher to propose polarity switching technology, approach anode technology and inject slow
Rush solution technique, although improve to some extent but still achieving no breakthrough property progress.
The present invention proposes that using a kind of composite electric soil restoring device and method that magnetic field is combined with electric field emphasis goes
Except the heavy metal contaminants such as Cu2+, Pb2+, Fe3+ in soil.Compared with traditional electronic soil remediation method, prosthetic device is added
Electromagnetic field generating coil, changes the mobile route of anion, cation using long-range navigation magnetic force, reduces anion, cation
Concentration degree.Meanwhile, by exchanging electric field and magnetic direction respectively, H+ ions and OH-ion can be neutralized, it is to avoid soil acid
Change.The enforcement of the present invention has to environmental protection to promoting the development of electronic soil restoring technology with important theory value
Important actual application value.

Earth repairs pond, and positive and negative electrode is arranged on repairs pond length direction both sides, and coil is used to produce along pond four sides uniform winding is repaired
Even magnetic field.
By the improvement of said structure, negative ions are caused mobile route to be sent out by electric field force and long-range navigation magnetic force force action
Fringe region that is raw to change, being no longer gathered in surrounding them and be generally evenly distributed on reparation pond width, contributes to reduction
Polarization phenomena, are easy to subsequently focus on pollutant.
Wherein, positive-negative electrode plate used adopts graphite material, is powered by dc source, voltage 220V ~ 230V, changes direct current
Electric both positive and negative polarity is capable of achieving the conversion of direction of an electric field.
Wherein, electromagnetic field generating coil is using the copper coil of bag paint, diameter 0.5mm ~ 1mm, the number of turn 50 ~ 200, the concrete number of turn
Can require to adjust according to magnetic field intensity, magnetic field intensity 16mT ~ 50mT.
Wherein, graphite electrode plate is fastened by phenolic resin bracket clamp, and above-below direction can adjust.
Wherein, electromagnetic field generating coil is changed direct current both positive and negative polarity and is capable of achieving magnetic by powered by direct current, voltage 220V ~ 230V
The conversion of field direction.
In common electric soil restoring device, due to the electrophoresis behavior of negative ions, electrode surface is made to cover pollutant
And impurity, the operating efficiency and service life of electrode are seriously reduced, and electrode are no longer deposited in by above-mentioned improvement negative ions
Surface and be generally evenly distributed in reparation pond both sides elongated zones, improve efficiency and life-span.
