| titleOfInvention | Soil oxidation-solidification stabilization remediation agent and using method thereof |
| abstract | The invention discloses a soil oxidation-solidification stabilization restoring agent and a using method thereof. According to the invention, through the molecular oxygen activation process in the zero-valent iron and disilicate system, the organic matters in the polluted soil are oxidized and removed, the interference of the organic matters on the soil solidification and stabilization process is reduced, and meanwhile, the mobility of the heavy metal polluted soil is greatly reduced through oxidation on the reductive substances such as arsenite radicals, selenite radicals and sulfide ions which may exist in the heavy metal polluted soil. Then, calcium oxide/calcium hydroxide is added, and the heavy metal ions (copper, lead, cadmium, mercury and the like) are stabilized and immobilized through iron minerals formed by residual zero-valent iron, calcium silicate compounds and the like. The remediation agent can be used for carrying out oxidation-solidification stabilization on heavy metal contaminated soil or organic matter and heavy metal combined contaminated soil with different pollution degrees, and products after solidification stabilization can be backfilled or used for other purposes. |
