Abstract

Inorganic waste sulfuric acid containing heavy metal ions is difficult to treat and has low recycling efficiency, resulting in great harm to the water, soil, and human living environments. In this paper, research of membrane separation technology to recover sulfuric acid is reviewed and analyzed, and its development direction prospected. The analysis shows that membrane contamination restricts the application of membrane distillation. Diffusion dialysis has the advantages of low energy consumption and high purity of sulfuric acid recovery, but the recovery speed is slow and time-consuming. Electrodialysis has the advantages of high sulfuric acid recovery and short process, but it has some problems such as high energy consumption and H⁺ leakage. The combined process of vacuum film distillation and mechanical steam recompression can greatly improve the utilization rate of latent heat. The coupling process, in which electrodialysis or diffusion dialysis and membrane distillation are performed after the waste sulfuric acid has been pretreated with ceramic membrane, is an important way to effectively solve the existing problems. According to the characteristics of impurities in inorganic waste sulfuric acid, it is an important direction for efficient and comprehensive utilization to produce corresponding sulfate products.

膜分离法回收无机废硫酸的研究进展

含重金属离子的无机废硫酸难以处理，回收效率低，对水、土壤和人类生存环境危害很大。本文对膜分离技术回收硫酸的研究进行了综述和分析，并对其发展方向进行了展望。分析表明，膜污染制约了膜蒸馏的应用。扩散透析具有能耗低、回收硫酸纯度高的优点，但回收速度慢，耗时长。电渗析具有硫酸回收率高、工艺流程短等优点，但存在能耗高、H+泄漏等问题。真空膜蒸馏与机械蒸汽再压缩相结合的工艺可以大大提高潜热的利用率。废硫酸经陶瓷膜预处理后进行电渗析或扩散渗析与膜蒸馏的耦合工艺是有效解决存在问题的重要途径。根据无机废硫酸中杂质的特点，生产相应的硫酸盐产品是高效综合利用的重要方向。
