摘要
不锈钢酸洗过程中会产生废液,其产量大,酸性强,难处理。介绍了酸洗废液的产生、组成、危害及酸回收技术(扩散渗析、电渗析、膜蒸馏、蒸酸法、热解法)和金属回收技术(沉淀、离子交换、溶剂萃取、结晶)的原理及研究现状,指出了现有方法的工业化应用限制因素,以期为酸洗废液的综合治理提供参考。
A large amount of spent pickling liquors produced in stainless steel pickling process is strong acidity and unwieldiness.The generation, composition, hazard and operating principles and research status of acid recovery technologies(diffusion dialysis, electrodialysis, membrane distillation, evaporation of acid, pyrolysis) and metal recovery technologies(precipitation, ion exchange, solvent extraction, crystallization) are introduced.The limiting factors of industrial application of existing methods are pointed out to provide a reference for comprehensive treatment of spent pickling liquors.
