| titleOfInvention | A kind of treatment method based on Friedel salt stabilization/solidification of arsenic sulfide slag |
| abstract | The invention discloses a treatment method based on Friedel salt stabilization/solidification of arsenic sulfide slag. The waste incineration fly ash, aluminate cement and arsenic sulfide slag are mixed uniformly to obtain a mixture, an alkali activator is added to the mixture, and the mixture is uniformly stirred and then cured. An arsenic-containing solidified body was obtained. The present invention utilizes waste incineration fly ash as the main matrix, and replaces traditional cement with active aluminum-rich aluminate cement as the component regulator, so that a large amount of Friedel salt is formed in the solidified matrix to stabilize/solidify the arsenic sulfide slag, The leaching toxicity of arsenic in the solidified body is greatly reduced to below 5mg/L, and the compressive strength is above 10MPa. |
