摘　　要：对乙烯废碱液综合治理过程中油类物质(包括悬浮物)的去除、剩余碱的综合处置及硫化物的处理等几个方面的研究进展进行了综述,指出乙烯废碱液的再生回用是其治理的发展趋势,针对乙烯废碱液的脱硫、脱碳再生技术存在的问题提出了解决方案。The research progress in several technologies for the comprehensive treatment of spent caustic of ethylene cracking, including the removal of oil, the treatment of left alkali and sulfide, is summarized. The development trend of the treatment of the spent caustic of ethylene cracking is presented that the spent caustic can be regenerated and the regenerated caustic can be circulated for alkali wash. Meanwhile, the countermeasures are put forward to solve the problems with the technologies for the regeneration of spent caustic of ethylene cracking in desulfm＇ization and decarbenization.
