摘要
甲基异丁基甲酮(MIBK)是高浓煤化工含酚废水处理中萃取脱酚优选萃取剂。总结了与溶剂萃取脱酚紧密相连的甲基异丁基甲酮-酚/有机酸-水液液相平衡研究现状。也对围绕甲基异丁基甲酮萃取脱酚为核心的酚氨回收流程变革过程进行回顾,同时对酚氨回收设计及MIBK相关的萃取运行及研究提出思路,为极大稳定后续生化处理的操作提供方便。
The methyl isobutyl ketone(MIBK)is the best extractant for extraction and dephenolization of phenolic wastewater from high concentration coal chemical industry.he research status of liquid-liquid equilibrium of methyl isobutyl ketone phenol/organic acid,which is closely related to solvent extraction dephenolization,was summarized.The innovation process of phenol ammonia recovery process centering on the extraction and dephenolization of methyl isobutyl ketone was reviewed.The ideas of phenol ammonia recovery design and MIBK extraction operation and research were put forward,which provided convenience for the operation of subsequent biochemical treatment.
