Ring.For Pollution In Soil, a variety of recovery techniques such as biology, physics and chemistry are have now been developed, and in practical application
In, peripheral doses are influenced by factors such as soil heterogeneity, permeability, and chemical remediation can produce the accessory substance of toxicity bigger.Mesh
It is preceding have the advantages that can in-situ immobilization, the microorganism remediation technology of non-secondary pollution become research hotspot, microorganism is to organic
The self-purification speed of pollutant limits its practical application slowly.
Bacteria bed technique is a kind of well foster wastewater treatment of the various purification process such as synthetic filter, absorption and biological agent
Technique, integrates biological oxidation and retention suspended solid, has certain degradation capability to organic pollution.Bioelectrochemistry system
System is a kind of new bio reactive mode for collecting biological oxidation and highly being coupled with electrochemical reaction, utilizes biology and electrochemistry
Synergistic effect oxygenolysis organic pollution, have and promote electron transfer rate, so that the features such as improving biodegradable level.
Research finds that bioelectrochemistry technology can deeply repair oil by improving the removal rate of total petroleum hydrocarbon in oil-polluted soils
Pollute salt affected soil.Research shows that external source electric energy can improve microbial activity and microbial diversity is had an impact, so that
Positive effect is played maintaining the stability of pollutant removal.
Hydrophobic porous biology anode electrode can improve the adhesion amount of microorganism on the electrode, the soil in improving to solution
The oxygenolysis of soil organic pollutant is promoted while earth Adsorption of Organic amount, there is solubilising and complexing, chelating
The mobility of pollutant in soil can be increased with the surfactant for reducing the effects such as interfacial surface tension, will can be adsorbed in soil
Soil organic pollutant in earth parses leaching into aqueous solution, becomes a kind of common soil restoring technology.
Solar energy is a kind of regenerative resource for cleaning, being easy to get, and electrical energy drive bioelectrochemical is produced using photovoltaic
System can not only improve the remediation efficiency of contaminated soil, and greatly reduce the removal cost of soil pollutant.
The content of the invention
The purpose that the present invention wants is to provide a kind of solar photovoltaic driving using solar energy photovoltaic system as electrical drive power
