癸二酸生产中甲酚废水治理方法的进展

对用蓖麻的生产癸二酸过程中产生的甲酚废水的各种处理方法进行了评述。在这些处理方法中，ＱＨ－１型络合萃取剂萃取法的处理效果最佳，废水经处理后酚浓度可达到国家排放标准。该法的投资较少，且回收的甲酚钠可回用于生产。经济上较合理，是一种比较理想的处理方法。

Progress in Treatment Processes of Cresol-Containing Wastewater from Sebacic Acid Production

The treatment processes of acidic wastewater containing cresol from the produc tion of sebacic acid from castor oil are reviewed in this paper. Among the treatment processes,the solvent extraction process with QH-1complex extractant is the most cost effective one.The treated wastewater can meet the national discharge standard,and the recovered sodium formate can be re-used to production.
