Description
Technical field
The present invention relates to the present invention relates to soil protection technical fields, and in particular to a kind of contaminated soil elution repairing and treating
System.
Background technique
Soil leaching refers to and injects or penetrate into flushing liquor in the soil, it is made to flow through the soil layer that need to be administered, parses in soil
Pollutant, then to the flushing liquor containing pollutant carry out processing and reuse process.Leacheate can be water, chemical solvent or
Other fluids that pollutant may be eluted from soil.The absorption-of the changeable soil of the injection of leacheate and pollutant is de-
Attached characteristic, oxidation-reduction potential, interfacial tension, pH value and distribution, dissolution, precipitated form etc., to increase the molten of pollutant
Xie Du makes it form lotion with solution or chemically react, pollutant in soil is promoted to remove.The soil texture, pollution species
Type and occurrence status have a major impact the effect of Soil leaching.Soil douching technique can be used for radioactive substance, organic matter, again
The processing or pre-treatment of metal or other inorganic matter contaminated soils, the pollutant in gravel, sand, fine sand and similar soil more hold
Easily it is leached out, and the then more difficult elution of the pollutant in clay.Soil is rinsed there are many way of realization, including in-situ immobilization and
Showering.
The mechanism of soil fixing metal can be divided into two major classes: first is that being adsorbed on the surface of soil constitution with ionic state；Second is that
Form the precipitating of metallic compound.Its principle of Soil leaching is acted on the heavy metal in reagent and solid phase of soil, is formed molten
The heavy metal ion or metal complex of solution property, then rush pollutant to outside root layer with clear water, recycle containing certain coordination
The compound shower soil of body, is allowed to form more stable complex compound with heavy metal ion;Or with the solution with anion, such as
Carbonate, phosphate rinse soil, and heavy metal is made to form compound precipitation.The key problem in technology of this method is to find one kind to mention
The heavy metal of various forms is taken, and does not destroy the leacheate of soil texture.Currently, the leacheate for washed off soil is more, packet
Include organic or inorganic acid, alkali, salt and chelating agent.Blaylock etc. examines citric acid, malic acid, acetic acid, EDTA, DTPA to print
Spend the effect that leaf mustard absorbs Cd and Pb.Wu Longhua research discovery EDTA can obviously reduce soil to the absorptivity of copper, absorptivity with
Desorption efficiency and the logarithm of the EDTA amount of addition are in significant negatively correlated.Soil leaching, which is eluted or accumulated with column, elutes more practical and warp
Ji suitable for the soil remediation of the small pollution weight of area, but also easily causes secondary pollution, leads to the leaching loss of certain nutrients and sinks
It forms sediment, destroys soil microaggregate structure, while being easy to cause underground water pollution.
Current Soil leaching device mode is simply extensive, and leacheate is directly sprayed to the mode of Soil leaching, these are repaired
Multiple liquid or water profound can not enter inside soil, therefore the efficiency eluted is lower, and repairing effect is poor, water resource waste
Seriously, secondary pollution is caused without processing after pollutant in leacheate absorption soil.
