一、前言 对特钢酸洗废液国内外较成熟用于生产的处理方法有蒸发法,萃取法美国用多层电渗析在硫酸、盐酸酸洗液中回收游离酸。 我们采用隔膜电解法处理硝、氟酸酸洗废液工艺在1982年7月由上海市冶金局组织并通过了技术鉴定,代表们一致认为该工艺是可行的,设备简单,操作、维修方便,占地小,是回收和处理酸洗废液的一种新的
I. Introduction Precipitation of special steel pickling waste at home and abroad for the production of more mature methods of evaporation, extraction method using multi-layer electrodialysis in the United States sulfuric acid, hydrochloric acid pickling solution in the recovery of free acid. We use the diaphragm electrolytic treatment of nitrate, acid pickling waste water technology in July 1982 organized by the Shanghai Metallurgical Bureau and passed the technical appraisal, the delegates agreed that the process is feasible, simple equipment, easy operation and maintenance, Small footprint, is a new recycling and processing pickling waste
