摘　　要：采用扩散渗析法处理化纤工业酸性废水,对原水及模拟水进行对比实验,结果表明,在废酸液与回收液流速为15～20mL/min时,酸回收率、COD与硫酸纳去除率可以达到70%～80%,且酸性废水经浓缩处理后,酸回收效果较好。The acid wastewater was treated by diffusion dialysis in chemical plant.The result showed that when the flow rate of acid wastewater and recovered liquid was 15～20 (mL/min),the acid recovery,COD removal and sodium sulfate removal all reached 70%～80%.The acid recovery effect was better after wastewater was concentrated.
