The invention discloses a method for restoring lead polluted soil with amino trimethylene phosphonic acid (ATMP), which has the advantages of higher biodegradability and higher rinsing efficiency. The method comprises the following steps: accurately weighing 1.00g of lead polluted soil sample, adding a 10-70% ATMP solution in a solid-to-liquid ratio of 1:25, oscillating at room temperature, standing, centrifugating and filtering to complete the rinsing process, wherein the oscillation time is 12 hours, the standing time is 12 hours, the centrifugating speed is 4000 r/min, and the centrifugating time is 20 minutes. The lead concentration of the polluted soil is 1000-4020 mg.kg<-1>. By using the ATMP for reinforced restoration of the lead polluted soil, the method has the characteristics of high restoration efficiency, high operability, low environmental risk and the like.
Description
Technical field
The present invention relates to lead-contaminated soil drip washing recovery technique field, specifically a kind of method of utilizing ATMP remediating lead-contaminated soil.
Background technology
Plumbous solubility in soil is little, and the holdup time is long, is a kind of nondegradable environmental contaminants, after the accumulation of table soil, not only affects output and the quality of crops, and affects human health by food chain.Plumbous body injury is to multisystem, many organs, plumbous as central nervous system poisonous substance, even more serious to children's health and intelligent harm.In recent years, be accompanied by mining, urbanization process, communications and transportation, Wastewater Irrigation in Farmland, agricultural sludge etc., make a large amount of lead elements enter soil system, ecological environment and human health in serious threat, and Lead Pollution in Soil is administered with reparation extremely urgent.
Drip washing technology is a kind of effective ways of repairing polluted soil.In general, chemical leaching technology refers to by promoting pollutant in soil environment to dissolve or the solvent of migration, by hydraulic head, promote cleaning fluid, be injected in contaminated soil layer, and then the liquid that includes pollutant is extracted from soil layer, carry out the technology of separated and sewage disposal.Eluent for Soil leaching mainly comprises inorganic eluent, artificial chelating agent, surfactant, natural organic acids etc. at present.EDTA etc. have stronger activation capacity and selective preferably to Pb, but along with going deep into of studying, find that the heavy metal chelate of these chelating agents activation can, to depth of soils diafiltration, cause secondary pollution.
ATMP (ATMP) is a kind of organic phospho acid, organic phospho acid is the compound that has one or more phosphonyl groups in molecule, because organic phospho acid compounds can generate stable chelate with contents of many kinds of heavy metal ion within the scope of wider pH, and toxicity is little, synthetic method is simple, and raw material is easy to get, cheap, the organic phosphine acids chelating agent generating is easy to be biodegradable, and has in succession obtained the attention of various countries.But ATMP is just applied to the industries such as water treatment at present, lack the correlative study of repairing at Soil leaching.
Summary of the invention
The object of the present invention is to provide a kind of effective and low method of utilizing ATMP remediating lead-contaminated soil of environmental risk.
In order to realize foregoing invention object, the technical solution used in the present invention is as follows:
Containing using ATMP on the soil of pollutant lead, the strong chelation drip washing remediating lead-contaminated soil by it with heavy metal lead, thereby the object that pollutant in soil lead is removed in realization.It is characterized in that: accurately take 1.00 g lead contamination soil samples, according to solid-to-liquid ratio 1:25, adding concentration is 1 ~ 70% ATMP solution.Standing 12 h after 12 h that vibrate under room temperature, centrifugal 20 min of 4000 r/min, filter, and measure the content of heavy metal lead in supernatant.Contaminated soil lead concentration is 1000 ~ 4020 mgkg
-1.
Advantage of the present invention is: the ATMP that experimental results show that is repeatedly a kind of more satisfactory eluent that lead-contaminated soil is repaired that can be used for, and compared with prior art, it has stronger biological degradability, and elution efficiency is higher.The present invention adopts the measure of ATMP strengthening remediating lead-contaminated soil, and its method has the features such as remediation efficiency is high, workable, environmental risk is low.
The specific embodiment
embodiment 1.
Accurately take the artificial lead contamination soil sample of 1.00 g, heavy metal-polluted soil lead concentration is 1000 mgkg
-1, according to solid-to-liquid ratio 1:25, adding concentration is 1,5,10,15,20,25,30% ATMP solution.Standing 12 h after 12 h that vibrate under room temperature, centrifugal 20 min of 4000 r/min, filter, and measure the content of heavy metal lead in supernatant, each reprocessing 3 times.
The impact of table 1 ATMP on heavy metal lead clearance.
| Eluent concentration (%) | CK | 1 | 5 | 10 | 15 | 20 | 25 | 30 |
| Clearance (%) | 10 | 22 | 38 | 65 | 73 | 88 | 85 | 86 |
Result shows, adopts vibration drip washing mode, utilizes ATMP to repair artificial lead-contaminated soil, and heavy metal Pb clearance maximum reaches 88%.
embodiment 2.
Accurately take the artificial lead contamination soil sample of 1.00 g, heavy metal-polluted soil lead concentration is 2000 mgkg
-1, according to solid-to-liquid ratio 1:25, adding concentration is 5,10,15,20,30,40,50% ATMP solution.Standing 12 h after 12 h that vibrate under room temperature, centrifugal 20 min of 4000 r/min, filter, and measure the content of heavy metal lead in supernatant, each reprocessing 3 times.
The impact of table 2 ATMP on heavy metal lead clearance.
| Eluent concentration (%) | CK | 5 | 10 | 15 | 20 | 30 | 40 | 50 |
| Clearance (%) | 9 | 17 | 35 | 41 | 63 | 76 | 83 | 80 |
Result shows, adopts vibration drip washing mode, utilizes ATMP to repair artificial lead-contaminated soil, and heavy metal Pb clearance maximum reaches 83%.
embodiment 3.
Utilize 2007 and adopt in the lead-contaminated soil of Shenyang Smeltery Factory and do vibration drip washing experiment, lead concentration is 4020 mg kg
-1.Accurately take 1.00 g and pollute soil samples, according to solid-to-liquid ratio 1:25, adding concentration is 10,20,30,40,50,60,70% ATMP solution.Standing 12 h after 12 h that vibrate under room temperature, centrifugal 20 min of 4000 r/min, filter, and measure the content of heavy metal lead in supernatant, each reprocessing 3 times.
