Abstract
The invention relates to a leaching liquid for repairing soil polluted by organic matters. The leaching liquid comprises main components as follows: bronyl acetate, diazole ketone, 1,4-dimethyl-piperazine, asiaticoside, 2-pyridinemethanol, ammonium citrate, [R-(R*,R*)]-butanal-2,3,4-trihydroxy, fatty alcohol-polyoxyethylene ether, polyoxypropylene diol, 4-aminoisoquinoline, polybasic carboxylic acid salt, sodium polyacrylate, sodium chlorite and tridecyl polyoxyethylene ether. The leaching liquid can repair the soil polluted by the organic matters, can also effectively remove heavy metal pollutants in the soil, and greatly reduces the soil repair cost.
Description
Technical field
The present invention relates to soil remediation field, be specially a kind of leacheate of repairing organic polluted soil.
Background technology
Along with the develop rapidly of city industrialization, urban soil and underground water industry and agricultural pollution serious gradually, Soil structure and ecotope are seriously damaged, quality of groundwater worsens, this not only causes agriculture production to be affected, more bring grave danger to the mankind and ecotope, therefore soil remediation is a current vital task urgently to be resolved hurrily.According to 2014 " national Soil Pollution Investigation publication " display, China's soil is generally polluted, and some areas soil pollution is serious, primarily to pollute for heavy metal contamination, is secondly Organic pollutants.And the pollution in soil is not often single a kind of pollutent, but multiple contaminates the compound pollution of depositing, the region that especially industrial development is comparatively general, heavy metal and Organic pollutants are all extensively present among soil.Therefore need badly propose a kind of can the techniques and methods of the compound pollution of rehabilitating soil.
The reparation of contaminated soil has multiple method, mainly comprises the methods such as peripheral doses, chemical redemption and biological restoration.And Soil leaching technology is as one of the important technical of chemical repair method, both can be used for restoration of soil polluted by heavy metal, and can be used for again repairing organic polluted soil, and received much concern especially.Soil leaching technology typically refers to by promoting that the liquid of pollutant dissolution/migration in edatope or other fluids carry out drip washing contaminated soil, makes absorption or be fixed on pollutent desorption on soil particle to dissolve and the technology removed.And the selection of leacheate is the key factor that contaminated soil drip washing is repaired.
At present, leacheate mainly can be divided into acids leacheate, artificial sequestrant leacheate, artificial surfactant and bio-surfactant leacheate etc.Usual acids leacheate comprises mineral acid and organic acid, and they can promote the dissolving wash-out of heavy metal in soil, and thus the drip washing reparation of heavy metal contaminated soil has good effect.But because acids leacheate can cause soil acidification, change the physico-chemical property of soil, make a large amount of Soil Nutrient Leaching, and spoiled soil microaggregate structure, and not good to the repairing effect of organic material contaminated soil.Artificial sequestrant is as EDTA, DTPA and NTA etc., due to stable complex compound can be formed with many metal ion species, make it from soil particle surface desorption/dissolving, therefore artificial sequestrant leacheate is widely used in drip washing repairing research and the practice of heavy-metal contaminated soil.But artificial sequestrant does not have keying action to organic pollutant, therefore can not repairing organic polluted soil.In recent years, artificial surfactant and bio-surfactant leacheate are widely used in the repairing research of organic material contaminated soil.The ultimate principle of tensio-active agent drip washing repairing organic polluted soil is strengthening solubilising by tensio-active agent and mobilization, strengthens organic contaminants in soil in the solubleness of aqueous phase and mobility, to reach the object of soil remediation.Research shows that artificial surfactant and bio-surfactant leacheate have good elute effect to Persistent organic pollutants such as PAHs and PCBs.For the drip washing reparation of heavy-metal contaminated soil, artificial surfactant does not have good effect, though and bio-surfactant has repairing effect, be subject to the restriction of some conditions such as soil pH value, organic content, and limited efficiency.
Therefore, a kind of novel leacheate organism and heavy-metal contaminated soil being had to better drip washing effect is sought, by significant to the repairing and treating of contaminated soil.
