摘　　要：针对石油工业含油废水需达标外排或工业回用等需求,如何优选处理技术及促进相关技术方法的进步,叙述了石油工业含油废水处理技术,包括浮选与凝结技术、生物处理技术、膜分离技术、高级氧化工艺技术和组合工艺等的现状及研究进展。认为应深入研究含油废水的降解机理,并探寻适宜催化剂的反应机理;通过组合多种处理工艺或开发新工艺,克服单一处理工艺的局限性,如离心-电絮凝/光催化-活性炭吸附-膜分离的组合工艺;提高处理工艺的环保性。其中生物处理法、膜分离法、光催化降解法和超临界水氧化技术能避免二次污染,处理效果好,具有较为突出的发展潜力。In view of the needs of oily wastewater in the petroleum industry for discharge or industrial reuse, how to optimize the treatment technology and promote the progress of related technical methods, the treatment technology of oily wastewater from the petroleum industry was described. It mainly includes the current status and research progress of flotation and coagulation, biological treatment, membrane separation, advanced oxidation and combined technology. It is believed that the degradation mechanism of oily wastewater should be studied, and the reaction mechanism of suitable catalyst should be explored. The limitations of a single treatment process should be overcome by combining multiple treatment processes or developing new processes, such as the combined process of centrifugation-electric flocculation/photocatalysis-activated carbon adsorption-membrane separation. The environmental protection of processing processes should be enhanced. Among them, biological treatment, membrane separation,photocatalytic degradation method and supercritical water oxidation technology can avoid secondary pollution and exhibit excellent treatment effect,which has relatively outstanding development potential.
