| titleOfInvention | Recycling and zero-discharge treatment system and process for binary high-salt complex system nickel hydrometallurgy wastewater |
| abstract | The invention discloses a resource and zero discharge treatment system and method for binary high-salt complex system nickel hydrometallurgy wastewater, which comprises the steps of firstly removing organic matters by electrocatalytic oxidation and activated carbon adsorption, then adjusting the pH value of the wastewater to enable carbonate to be completely converted into sulfate, enriching and recycling heavy metals mainly containing nickel through ion exchange after precise filtration to obtain a sodium sulfate aqueous solution with organic matters and heavy metals removed, finally recycling anhydrous sodium sulfate in brine through spray drying, and simultaneously condensing and recycling dried water vapor for a production system. The invention not only effectively solves the treatment problem of the complex system nickel hydrometallurgy wastewater containing heavy metal, high-concentration compound salt and a small amount of macromolecular organic matters, but also realizes the recycling of the heavy metal nickel and the salt in the wastewater, and simultaneously, the condensed water can be reused in a production system, thereby really realizing the comprehensive utilization and zero discharge of the resources in the wastewater. |
