Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment, in particular to a colloidal palladium waste liquid recovery and reuse device. Background Art

[0002] Colloidal palladium waste liquid is a wastewater liquid containing palladium, which is usually caused by solvents and catalysts containing palladium compounds used in industrial production or laboratory chemical reactions. These wastewaters will contain high concentrations of palladium ions. If they are discharged directly into the environment without treatment, they will cause pollution and harm to the environment. Therefore, when treating colloidal palladium waste liquid, it is necessary to recycle the palladium metal in the waste liquid. At present, it is generally necessary to add an appropriate amount of chemical substances such as sodium hydroxide and sodium chloride to the waste liquid to react and generate solid precipitates, so as to achieve the purpose of recycling. However, the current recovery device cannot provide better reaction conditions, resulting in low recovery efficiency, and it is inconvenient to remove the palladium metal precipitate produced by the reaction. Therefore, we propose a colloidal palladium waste liquid recovery and reuse device to solve the above problems. Utility Model Content
