摘　　要：通过典型炼厂主要工艺废水中的来源、污染物组成和排放量的统计分析,并结合国内炼油企业的实际运行,讨论了国内炼油企业如何围绕酸性水、电脱盐废水和碱渣废水这三类废水开展工艺废水的分质处理和循环利用的工作,并指出进入21世纪以来,我国的炼油行业在炼油生产工艺的升级改造和清洁生产取得了明显成果,提升了污染源头控制能力,显著降低了各炼厂碱渣废水处理装置和污水处理场的运行负荷,极大地减轻了炼厂废水污染治理的工作压力。Process wastewater generated by a refinery typically can be segregated into three categories:sour waster,desalter effluent and spent caustic according to the sources,specification and flowrate of the wastewater streams.The paper describes various wastewater separate treatment processes,recycling and reuse practices with respect to the three categories of refinery process wastewater.Since the beginning of the 21st century,it also points out that there are significant achievements in Chinese refining enterprises due to upgrade of crude oil refining processes and clean production of Chinese refineries,where the operating load of alkali slag wastewater treatment plant and sewage treatment plant of each refinery has been significantly reduced,and the working pressure of wastewater treatment of refinery has been greatly reduced.
