The invention discloses an intelligent regeneration and reuse process manufacturing method for a waste electrolyte in the technical field of regeneration and reuse equipment. The method comprises thefollowing steps of S1, removing copper from the waste electrolyte; S2, extracting metal salt; S3, purifying the waste electrolyte; S4, callback of the waste electrolyte; S5, separating the waste electrolyte. The waste electrolyte intelligent regeneration and reuse process is reasonable in structural design, an ultrafiltration membrane system is adopted to intercept macromolecular organic matter ina high-concentration sulfuric acid solution, the problem that a diffusion dialysis anion membrane is blocked is solved, therefore it is guaranteed that the diffusion dialysis anion membrane can workcontinuously, and therefore, the acid in the waste electrolyte is reused.
Description
technical field [0001] The invention relates to the technical field of regeneration and reuse equipment, in particular to an intelligent regeneration and reuse process manufacturing method of waste electrolyte. Background technique [0002] In the production process of the electrolytic copper industry, as time goes by, the impurity ions in the electrolytic bath, such as: nickel, zinc, arsenic, antimony and bismuth, will become higher and higher, which will directly affect the electrolytic copper. Normal production, therefore, electrolytic copper production enterprises will produce a large amount of waste acid containing metal ions. At present, there are two main methods for the treatment of waste electrolyte: entrust a qualified third party to process, and the treatment cost is about 4,500 yuan / ton. The treatment cost is very expensive, which is unacceptable to most enterprises; the acid-base neutralization method needs to consume a large amount of caustic soda, and will gen...
