Arsenic-containing neutralization slag solidifying and stabilizing agent and method for solidifying and stabilizing arsenic-containing neutralization slag by using same
The invention relates to an arsenic-containing neutralization slag solidifying and stabilizing agent and a method for solidifying and stabilizing arsenic-containing neutralization slag by using the same, belonging to the technical field of hazardous waste treatment and disposition. The arsenic-containing neutralization slag solidifying and stabilizing agent is composed of a stabilizing agent A and a solidifying agent B, wherein the stabilizing agent A is composed of lime and ferrous sulfate, and the solidifying agent B is composed of cement and fly ash. The arsenic-containing neutralization slag solidifying and stabilizing agent is composed of the following components in percentage by weight: 40-60% of cement, 15-35% of fly ash, 5-10% of lime and 6-15% of ferrous sulfate. The arsenic-containing neutralization slag solidifying and stabilizing agent has favorable solidifying effect for the heavy metal arsenic in the neutralization slag, and the arsenic leaching rate after solidification can satisfy related requirements in GB5085.3-2007. All the raw materials are conventional raw materials and reagents which are cheap and accessible, so the agent cost is lower, thereby greatly lowering the disposition cost of the arsenic-containing neutralization slag.
