Problems solved by technology
[0002] The production of electrolytic copper will produce a large amount of waste electrolyte in the production process. The electrolyte mainly contains sulfuric acid, various metal ions and a small amount of organic matter. The existing technology has made nickel, iron, aluminum, etc. The metal has been recovered and the waste liquid has been reduced at the same time, but the amount of waste liquid produced every day is still quite huge. At present, the method of acid-base neutralization is mainly used in the market, which will generate a large amount of solid waste and the cost of environmental protection treatment in the later stage is very high

The invention provides a diffusion dialysis membrane separation system suitable for recycling an electrolytic copper waste liquid. The system comprises a waste liquid acidity regulating device and a membrane separation device, wherein the waste liquid acidity regulating device comprises a regulating tank for regulating the acid concentration of the electrolytic copper waste liquid to be not more than 500 g / L; the membrane separation device comprises a basic structural unit; the basic structure unit is divided by an anionic membrane to form a dialysis chamber and a diffusion chamber; and the membrane separation device adopts countercurrent operation, a waste acid liquid and a receiving liquid are respectively introduced into two sides of the anion homogeneous membrane, and a regenerated acid liquid is separated by utilizing the diffusion dialysis principle. A unique and advanced diffusion dialysis membrane separation technology is adopted for treating the electrolyte waste liquid obtained after recovery of nickel, iron, aluminum and other metals through evaporation and filtration treatments, and the electrolyte waste liquid can be regenerated to a copper electrolysis tank for cycleuse, so the enterprise cost is greatly saved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of electrolytic copper, in particular to a diffusion dialysis membrane separation system suitable for regeneration and reuse of electrolytic copper waste liquid. Background technique [0002] The production of electrolytic copper will produce a large amount of waste electrolyte in the production process. The electrolyte mainly contains sulfuric acid, various metal ions and a small amount of organic matter. The existing technology has made nickel, iron, aluminum, etc. The metal has been recovered and the waste liquid has been reduced at the same time, but the amount of waste liquid produced every day is still quite huge. At present, the method of acid-base neutralization is mainly used in the market, which will generate a large amount of solid waste and the cost of environmental protection treatment in the later stage is very high . [0003] On the other hand, my country's environmental management department is streng...
