| titleOfInvention | Composite gelling agent for arsenic-containing waste residue detoxification and preparation method and application thereof |
| abstract | The invention discloses a composite gelling agent for detoxifying arsenic-containing waste residues, and a preparation method and application thereof. The composite gelling agent is prepared from leaching slag rich in elements such as silicon, iron, calcium, aluminum, manganese and the like through alkaline hydrothermal, roasting and ball milling processes, can provide alkaline metal ions combined with arsenic, provide groups coordinated and adsorbed with the arsenic, and can generate ferrosilicon aluminate hydrate with high strength and low permeability to provide microcosmic wrapping so as to reduce the mobility of the arsenic and further achieve the aim of gelling and detoxifying the arsenic-containing waste slag. The composite gelling agent disclosed by the invention is wide in raw material preparation, simple in process, low in cost and short in period, has a stable treatment effect and a small volume ratio compared with the traditional cement curing, is easy to industrially apply, and can be safely buried and disposed, and all indexes of arsenic-containing waste residues after treatment can stably meet the limit requirements specified in hazardous waste landfill pollution control standards (GB 18598-2019). |
