Abstract
The invention discloses a high-lead-content soil restoration agent. The invention is characterized in that the restoration agent is composed of powder and a solution. The powder is composed of the following components in parts by weight: 60-80 parts of cement, 20-30 parts of quicklime and 2-10 parts of clay. The solution is composed of a solute and water in a weight ratio of 1 to 2; and the solute is composed of the following components in parts by weight: 40-50 parts of phosphorus-base compound and 2-10 parts of sodium dimethyldithiocarbamate. The restoration agent can be used for restoring high-lead-content soil, can convert Pb ions into ore-type compounds, and can well keep the stability of the Pb ions. By using the principle that the ion mineralization stabilizer can be quickly subjected to mineralization reaction with Pb ions, the treatment reaction time and maintenance time are greatly shortened, the polluted soil treatment capacity in unit time is enhanced, and the occupied land area is smaller, thereby greatly lowering the cost investment and enhancing the land utilization ratio. Therefore, the high-lead-content soil restoration agent is suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of soil remediation medicament, specifically refer to a kind of high leaded soil remediation medicament。
Background technology
At present, people are when the soil that heavy metal exceeds standard is administered, and the following three kinds of renovation agents of main employing are repaired, i.e. ion mineralising stabilizer, heavy metal ion agent for capturing and heavy metal ion chelating agent。The main component of above-mentioned three kinds of renovation agents is clayed soil and adds Sodium Dimethyldithiocarbamate, phosphorio compound and Cabase compound etc., its Principles is all react by compound and heavy metal ion, generate a kind of be not readily dissolved in water, acid salt or alkaloids, and then make heavy metal ion no longer become free state, thus preventing heavy metal ion from water or soil environment are carried out secondary pollution, it is finally reached the effect that heavy metal ion is stable。
But, the reparation medicament being specifically designed for high leaded soil and every total lead content of 1 kilogram of soil more than 15000 milligrams not yet occurs at present, therefore needs a kind of high leaded soil remediation medicament of exploitation badly。
Summary of the invention
It is an object of the invention to provide a kind of high leaded soil remediation medicament, be specifically designed for high leaded soil and repair。
The present invention is achieved through the following technical solutions:
A kind of high leaded soil remediation medicament, comprises the following steps:
A kind of high leaded soil remediation medicament, this reparation medicament is made up of powder and liquor；Described powder is the cement of 60～80 by weight portion, and the quick lime of 20～30 and the clay of 2～10 form；Described liquor is made up of by weight the ratio for 1:2 with water solute, and described solute is made up of the Sodium Dimethyldithiocarbamate of the phosphorio compound that weight portion is 40～50 and 2～10。
Further, described powder is the cement of 65～75 by weight portion, and the quick lime of 22～28 and the clay of 10～12 form。
Further, described powder is the cement of 70 by weight portion, and the quick lime of 25 and the clay of 11 form。
Meanwhile, described solute is made up of the Sodium Dimethyldithiocarbamate of the phosphorio compound that weight portion is 42～48 and 3～8。
Further, described solute is made up of the Sodium Dimethyldithiocarbamate of the phosphorio compound that weight portion is 45 and 5。
In order to realize the present invention better, the matching range of the weight of described powder and the volume of liquor is: during the Pb concentration≤50000ppm of the every 1Kg contaminated soil of 15000ppm <, powder value is 6～8Kg, and liquor value is 4～6L。
More excellent, the matching range of the weight of described powder and the volume of liquor is:
During the Pb concentration≤40000ppm of the every 1Kg contaminated soil of 20000ppm <, powder value is 6.5～7.5Kg, and liquor value is 4.5～5.5L。
Matching range in order to ensure effect, the weight of described powder and the volume of liquor is:
During the Pb concentration≤40000ppm of the every 1Kg contaminated soil of 30000ppm <, powder value is 7～7.5Kg, and liquor value is 5～5.5L。
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) the reparation medicament of the present invention can be repaired for high leaded soil, Pb ion can be converted to Ore type compound, such that it is able to well maintain the stability of Pb ion, utilize the principle that ion mineralising stable pharmaceutical can quickly occur mineralising to react with Pb ion, the reaction processed and curing time being all greatly shortened, improves the treating capacity of unit interval internal contamination soil, the land area taken needed for it is less, greatly reduce the input of fund, improve the utilization rate in soil。
(2) composition of reagent combination of repairing of the present invention own does not have the chemical substance of heavy metal or other danger, have higher safety, ensure that the normal growth of grown on soil crop after treatment is unaffected, further increase the utilization rate of soil。
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this。
Embodiment 1
A kind of high leaded soil remediation medicament, this reparation medicament is made up of powder and liquor；Wherein, described powder is the cement of 60 by weight portion, and the quick lime of 30 and the clay of 8 form。Described liquor is made up of by weight the ratio for 1:2 with water solute, and wherein, described solute is made up of the Sodium Dimethyldithiocarbamate of the phosphorio compound that weight portion is 40 and 10。The matching range of the weight of described powder and the volume of liquor is: during the Pb concentration≤20000ppm of the every 1Kg contaminated soil of 15000ppm <, powder value is 6～6.5Kg, and liquor value is 4～4.5L；During the Pb concentration≤30000ppm of the every 1Kg contaminated soil of 20000ppm <, powder value is 6.5～7Kg, and liquor value is 4.5～5L；During the Pb concentration≤40000ppm of the every 1Kg contaminated soil of 30000ppm <, powder value is 7～7.5Kg, and liquor value is 5～5.5L；During the Pb concentration≤50000ppm of the every 1Kg contaminated soil of 40000ppm <, powder value is 7.5～8Kg, and liquor value is 5.5～6L。
