Description
Technical field
The utility model is related to the chemical leaching system that a kind of farmland pollution is administered, and belongs to chemical leaching systems technology neck
Domain.
Background technology
The improvement that farmland pollution is administered substantially has following several method：
Electro reclamation belongs to in-situ remediation method, and processing cost is low, remediation efficiency is high, convenient post-treatment, it is not necessary to soil
The middle material for adding hostile environment, will not cause secondary pollution.But still suffering from some problems at present needs improvement：For example voltage draws
Play soil body heating and cause efficiency change, the technology is not high for the selectivity of pollutant, causes after the electrolysis of anode and cathode electrolyte
The change of soil pH value, treatment cost may be raised with the consumption of equipment in Practical Project.
Heat treatment restorative procedure is commonly used to repair mercury, the soil of selenium contamination.Microwave heating technique firing rate is exceedingly fast,
The thermal efficiency is high, applied widely, and can selectively heat, and separates and recovers some useful components.But skill is repaired in heat treatment
Art needs to consume substantial amounts of energy, easily causes the destruction of the soil organism and constitution water, also there is volatile mercury vapour and enters
Enter the problem of air causes atmosphere pollution.
Passivating technique needs the factors such as the property of the pollution level and soil of consideration heavy metal-polluted soil in itself to select again rationally
Passivation medicament, and calculate passivation medicament consumption.Wide variety of passivation medicament is generally industrial by-products in engineering,
Therefore the cost of passivating technique is relatively low, but passivating technique does not remove heavy metal at all from soil, it is therefore desirable to carry out long-term
Monitoring to prevent heavy metal from activating again.
Plant extraction recovery technique is small to agricultural land soil secondary pollution, but repairing efficiency is long, and large area plantation can be serious
The economic benefit of local farmers is influenceed, extensive use of the plant extraction recovery technique in heavy metal pollution farmland is govern.
Engineering measure method is initially used in countries such as Britain, Holland, the U.S., has reached the mesh of reduction hazard of contaminant
, it is a kind of effective administering method.But this method need to expend substantial amounts of manpower, financial resources and material resources, cost is higher, and not
Heavy metal can be fundamentally removed, there are land occupation, seepage and secondary pollution problems, therefore is not a kind of preferably improvement
The method of heavy metal pollution of soil.
Chemical leaching repairing method：Also have in industry and heavy metals in farmland pollution control carried out using chemical leaching technology,
But conventional chemical leaching, more by the way of wet method pulping, is configured to slurries by contaminated soil in elution pond, uses agitating paddle
It is sufficiently mixed uniformly, then carries out mud-water separation and remove heavy metal contaminants, this method energy consumption is big, destroy big to soil texture,
After the completion of elution, wastewater treatment pressure is big.
