色纤碱减量废水中对苯二甲酸的回收精制研究
Recovery and Refining of TA from Colored Alkali Reduction Wastewater
【摘要】 文章研究了酸析法从带色碱减量废水中回收对苯二甲酸(TA)过程,并且通过废水预处理进行TA的简单精制。结果表明,这种处理方法不但能大幅度降低碱减量废水的COD值,而且可以获得高纯度对苯二甲酸。另外,文章还对回收得到的对苯二甲酸的用途进行了简单分析。
【Abstract】 Separation process of terephthalic acid(TA)from colored alkali reduction wastewater by acidation was studied and TA was simply refined through pretreatment.Results showed that the method could not only decrease COD in wastewater greatly,but also obtain TA of high purity.Application of recovered TA was analyzed as well.
