| titleOfInvention | Harmless treatment method for arsenic-iron slag |
| abstract | The invention discloses a method for harmlessly treating arsenic-iron slag, which comprises the following steps: and uniformly mixing the arsenic-iron slag, the cement and the ammonium polyvinyl alcohol phosphate, adding water, stirring, injecting into a mold for molding, and then maintaining and demolding. According to the invention, the ammonium polyvinyl alcohol phosphate and the cement are preferably used as the curing agent, and the synergistic effect of the ammonium polyvinyl alcohol phosphate and the cement is realized, so that the obtained arsenic slag cured body has higher stability and lower compatibilization ratio. The product after the curing treatment is detected by a toxicity leaching experiment (TCLP), and the result shows that the toxicity leaching concentration of harmful elements such as arsenic in the leaching solution is far lower than the limit value specified in 'hazardous waste identification standard leaching toxicity identification GB 5085.3-2007', and the product can be stockpiled and buried. |
