摘要
介绍了离子交换工艺,离子交换树脂的交换原理,论述了 NaSCN 与 COD 的相关性,提出了污水回收装置进料流量及再生剂(NaOH)流量的设定值,为操作程序的时间更改提供了依据,使之提高了 NaSCN 的回收率,降低了腈纶的 NaSCN单耗。
Describe the mechanism of ion exchange process and ion exchange resin. Discuss the correlation between NaSCN and COD.Establish the setting value for the feed flow rate and regenerant(NaOH)of wastewater recovery unit. Provide the basis for time change of operating procedure.So as,to increase the recovery rate of NaSCN and reduce the unit consumpting of NaSCN for acrylon.
