Description
Technical field
The present invention relates to environmental pollution many technical tie-ups processing technology field, particularly relate to one and utilize AC field auxiliary southeast scape
The method of it remediating heavy metal soil.
Background technology
At present, soil pollution repair method main rationalization repairing method and biological restoration；Such as, traditional soil replacement method, change
Learn drip washing and biological restoration etc..Owing to having that cost is high, easily causing secondary pollution or destroy the defects such as Soil structure, these methods
It is difficult to the reparation of large area heavy-metal contaminated soil.
Phytoremediation, although environmental protection, but the rhizosphere to hyperaccumulative plant that most of heavy metal is difficult to orient moves,
Described, it is difficult to be continuously kept remediation efficiency.Single electromotion repairing technique method, although have remediation efficiency high, convenient post-treatment
Etc. advantage, but, owing to the method is restricted by the factor such as cost and operation, so the application prospect of its reality can be affected.
Electric repairing technique helps speed up the absorption of plant heavy metal element with combining of phytoremediation technology and is transported to plant
Thing overground part, thus realize the raising of remediation efficiency.DC electric field-plant combined repairing method, based on both sides electrode potential
Difference and produce voltage, by applying DC voltage in contaminated soil both sides, thus form electric-force gradient, make the weight in soil
Metal changes, and moves to electrode two ends under electric field action by the way of electromigration, EOF or electrophoresis, in this process
In, plant heavy metal absorbs, thus reaches the purpose of repairing polluted soil.
Application publication number is that the application for a patent for invention document of CN102125927A discloses and a kind of repaired by heavy-metal contaminated soil
Method, has the electrode of a pair insertion soil in the device that the method uses, its insertion depth takes 0.5 meter；To place in-between the electrodes
Plant root apply short interval time change electropolar direct current weak electric field excitation；Described short interval time is 3～5 hours；Institute
Stating direct current weak electric field is 0.1～1mA/cm2；And implement according to the following steps: (1) cultivation rehabilitation plant；(2) contaminated soil is measured
Middle heavy metal concentration, determines heavy metal pollution of soil region；(3) mark need repair soil region, construct reparation band with every
From band；(4) electrode and electrode control system are disposed；(5) plantation rehabilitation plant；(6) electric field is applied；(7) step (6) is repeated；
Until the heavy metal concentration in soil is down to claimed range；(8) isolation strip changes into repairing band, and former reparation band changes isolation strip into；Weight
Multiple step (5)～(7).The method applies feeble field switch polarity in root system of plant region, promotes heavy metal in soil pollutant
Desorbing and migration, promote that plant is to the absorption of pollutant and accumulation.
But, due to the displacement of charged particle, the two poles of the earth meta-acid or meta-alkali can be caused, be unfavorable for plant growing, so,
Processing procedure needs change polarity of electrode.And AC field-plant combined repairing method is unlikely to two because have employed alternating current
Pole meta-acid or the situation of meta-alkali, the beneficially growth of plant ground.
Application publication number is that the application for a patent for invention document of CN103406347A discloses one and can be used for heavy metal in Enriching soil
And organic method, the method forms electric field by building electrokinetic enrichment system in soil, is made by EOF, electromigration
With by the heavy metal accumulation in soil in a certain region, then carry out separating, purifying；Described electrokinetic enrichment system is straight by controllable
Stream power supply, anode chamber, cathode chamber, soil, electrode, cation exchange membrane composition；Anode chamber and anode, cathode chamber and negative electrode
Being positioned at the both sides of faradaic reaction system, soil is positioned at the centre of two electrodes, arranges cation exchange membrane between cathode chamber and soil,
Controllable DC source jointed anode and negative electrode；Electrolyte also need to be prepared at electric field two ends；Described electrolyte be water, acid solution,
One in chemical complexing agent EDTA solution, solution concentration is 0.01～1.0mol/L；Described method is by chemical complexing agent EDTA
Join cathode chamber, as the cathodic control liquid of faradaic reaction.
But, existing electronic-phytoremediation device is mostly confined to laboratory and uses, and again by making expensive, material
The impact of factors such as special (common laboratory all use graphite electrode), is carried out this Technique Popularizing to land for growing field crops, field so more difficult
Experiment.
Therefore, probe into the most simple and feasible a kind of AC field-plant restoration method, thus improve hyperaccumulative plant and administering weight
Effect in terms of technology contaminated soil, becomes hot issue urgently to be resolved hurrily.
