| titleOfInvention | Curing agent for composite heavy metal polluted soil and preparation and application methods thereof |
| abstract | The invention discloses a curing agent for composite heavy metal polluted soil and a preparation and application method thereof, wherein the curing agent comprises the following materials in percentage by mass: 40-65% of steel slag powder; light-burned magnesia 5-25%; 20-45% of phosphate activated bone meal. The invention has the advantages that: firstly, the curing agent can obviously reduce the heavy metal migration and toxic leaching amount in heavy metal polluted soil, is particularly used for an acid polluted site with high heavy metal content and more pollutant types, can be used as an environment-friendly material for resource utilization after polluted soil is repaired, and obviously reduces the environmental risk in secondary development and utilization of the polluted site; meanwhile, the curing agent has the advantages of easily available raw materials, low cost, simple preparation, convenient use and stable effect, and can be popularized and applied to curing stabilization repair of composite polluted sites on a large scale. |
