| titleOfInvention | A kind of plating waste residue recoverying and utilizing method |
| abstract | The present invention relates to a kind of plating waste residue recoverying and utilizing method, its main technological steps is: first electroplating sludge waste residue is carried out Oxidation Leaching, is namely diluted with water to solution and carries out aqueous phase leaching, then by Oxidation Leaching aaerosol solution isolated by filtration, obtains filter mud and filtrate; Reclaim after filter mud reduction is stable and make fertilizer or building materials raw material, filtrate sends into Waste Water Treatment, controls different condition (pH value), carry out fractional precipitation, the compound precipitates obtaining each heavy metal species reclaims respectively, poor metal, then as micro-centralized recovery.After wastewater treatment, recycling, for dilute solution or washing, view, environmental sanitation.It is last that available YHD is stabilizing agent specially used, and to carry out reduction to the residual heavy metal in filter mud and filtrate stable as required, make its no longer with water generation oxidation.The present invention can realize global optimization target and the effect of the cleaner production recycling economy of " zero-emission, pollution-free, complete utilization, increase benefit " of electroplating industry enterprise waste residue. |
