    Abstract: The present disclosure discloses recycling treatment equipment for recycling heavy metals from complexed heavy metal wastewater, and belongs to the technical field of wastewater treatment. The recycling treatment equipment includes a wastewater separation and concentration component, an oxidization and decomplexing component, an electrolytic recovery component, and an intelligent detection component. Wastewater containing complexed heavy metals is divided into fresh water and concentrated water by performing microfiltration, nanofiltration, and reverse osmosis purification pretreatment, and the fresh water is then recycled in a targeted manner, so that the equipment has energy conservation and discharge reduction effects, can decomplex and recycle heavy metals in the concentrated water, and also synchronously purifies the fresh water. The whole process has the advantages of simple operation, zero sludge, and low treatment cost, so that the equipment is suitable for being greatly promoted.
