摘　　要：近年来随着炼厂所加工原油的劣质化和成品油的提质升级,炼油过程中会使用NaOH对馏分进行精制,产生炼油碱渣。其中含有NaOH、Na_2S、NaHS、硫醇钠、环烷酸钠、酚钠等,属于高浓度、难降解、有毒的有机废水,是炼油过程中产生的主要污染物之一,直接排放会对环境造成严重污染。本文中总结了国内外炼油碱渣的处理方法,包括化学氧化法、生物氧化法、络合萃取法等,并指出了这些技术的优缺点和应用现状。Recently,with the upgrading of the refinery processing of crude oil and oil products of poor quality upgrade,refining process uses NaOH to purify fraction,and produces spent caustic. Spent caustic contains NaOH,Na_2S,NaHS,sodium thiol,sodium naphthenic acid,phenol sodium and so on,which belongs to high concentration,refractory toxic organic wastewater.Spent caustic is one of the main pollutants generated in the refining process,will cause serious environmental pollution if discharged directly. This article summarized the treatment of domestic and foreign refining spent caustic,including chemical oxidation,biological oxidation,complexation extraction method,and pointed out the advantages,disadvantages and application of these technologies.
