本文叙述了用渗析法回收锌电解废液中硫酸的工艺过程。本工艺采用离子交换膜,用单体渗析器测定了膜在两种不同电解液中的使用寿命。考察了Zn~(2+)、Mg~(2+)、及Cl~-在渗析过程中的行为。在试验室扩大试验中考察了影响渗析过程的主要因素,最后为工业生产推荐了两种可行的工艺流程。 This paper describes the use of dialysis recovery of zinc electrolysis waste sulfuric acid process. The process uses an ion exchange membrane, with a single dialysis separator membrane in two different electrolyte life. The behavior of Zn ~ (2 +), Mg ~ (2+) and Cl ~ - during dialysis was investigated. The main factors affecting the dialysis process were investigated in the laboratory expansion test. Finally, two feasible process flows were recommended for industrial production.
