| titleOfInvention | Heavy metal solidification stabilizing agent and preparation method and application thereof |
| abstract | The invention discloses a heavy metal solidification and stabilization agent, a preparation method thereof and application thereof in repairing soil polluted by compound heavy metals. The heavy metal solidification and stabilization medicament comprises the following raw materials: and (2) component A: the component A comprises the following raw materials by taking the total mass of the component A as 100 percent: 27% -35% of Portland cement, 12% -18% of fly ash, 25% -35% of activated blast furnace slag obtained by ball milling of blast furnace slag and desulfurized gypsum according to the mass ratio of 2-8: 1, 2% -10% of ferrous sulfate and 10% -16% of modified biomass carbon; and (B) component: the mass ratio of the phytic acid to the ferrous sulfate in the component A is 1: 2-6; and (3) component C: polypropylene fiber, which accounts for 0-6% of the Portland cement in the component A by mass; and (3) component D: zeolite accounts for 2 to 15 percent of the modified biomass charcoal in the component A by mass; and (3) component E: the mass ratio of the sand to the total mass of the components A to D is 1: 2-4. And uniformly mixing all the raw materials in a closed stirring and turning device according to the proportion to obtain the heavy metal solidification stabilizing agent. |
