摘　　要：化成箔行业电极箔腐蚀工艺产生的酸性废水,含有大量的游离酸,通常采用石灰中和的方式处理,处理成本高且不能回收酸性废水中的有用成分,还会产生大量的废水和废渣,造成二次污染。本文采用扩散渗析法综合处理化成箔行业酸性废水,回收废酸液中的硫酸和磷酸,实现资源的再利用,降低企业运行成本和环保压力。The acidic waste water produced in the foil corrosion process contains a large amount of acids,usually treated with lime neutralization.The treatment cost is high and the useful ingredients therein are not recovered with quite a large amount of waste water and waste solid produced.This paper treated the acidic waste effluent in foil forming industry by diffusion dialysis,and sulfuric acid and phosphoric acid therein were recovered.
