| titleOfInvention | Smelting wastewater deep thallium removal trapping agent and preparation method thereof |
| abstract | The invention provides a preparation method of a smelting wastewater deep thallium removal trapping agent, and relates to the technical field of smelting wastewater treatment. The invention takes palm leaves as main raw materials, the palm leaves are pretreated to be prepared into palm leaf activated carbon, H is introduced into the palm leaf activated carbon 2 And S, performing plasma treatment, and preparing the agent A and the agent B of the deep thallium removal trapping agent with a stabilizer, a complexing agent, a flocculating agent and the like, so that various heavy metals are separately precipitated and removed, the recovery treatment difficulty of solid wastes is reduced, the secondary pollution of the solid wastes to the environment is reduced, and the deep thallium removal trapping agent is suitable for the treatment and recovery of various smelting wastewater associated with thallium elements. The method has the advantages of low cost, simple and convenient operation, easy recovery and treatment of solid waste, strong trapping capability of thallium ions and other heavy metal ions, and wide application in treatment of thallium element associated various mineral smelting wastewater. |
