Abstract

Battery wastewater presents dual characteristics: significant treatment difficulty and high value in metal ion recovery due to the high concentration of heavy metal ions and strong acidity. The salt separation treatment scheme of acid-resistant separation membranes, nanofiltration membranes, and reverse osmosis (RO) membranes were employed. Based on the changes in salt content at different treatment stages, different types of RO membranes were selected accordingly. Combined with multi-effect evaporation technology, salt concentration and refinement were achieved, ultimately realizing the goals of salt recovery and zero wastewater discharge. The verifies the feasibility of the technical route and the reliability of membrane technology products were also demonstrated.

Key words： battery wastewater high-acid and high-salt wastewater membrane separation technology salt separation zero emission
