摘　　要：含油污水中的石油烃类化合物是一种稳定的有毒物质,采用传统的物理和化学方法难以彻底清除。通过对微生物降解石油烃的机理和影响因素分析,得出了能够处理高乳化度含油污水的生物处理方法。推荐并介绍了2种活性污泥法与生物膜法组合的处理工艺技术和关键设备的工作原理,并通过应用实例验证了2种组合工艺的处理效果。最后展望了适用于含油污水处理的复合生物反应器的意义和前景。The petroleum hydrocarbons contained in the oily sewage is a stable toxic substance, which can not be completely removed by using traditional physical and chemical methods. Through analysis on the mechanism and influential factors of microbial degradation of petroleum hydrocarbons, the biological treatment processes for treating highly emulsified oily sewage are put forward. Two kinds of activated sludge and biofilm combined treatment processes are proposed, and the key equipment is introduced. Case studies have been presented to illustrate the treatment effects of the two kinds of combined treatment processes. The outlook of significance and prospects of the hybrid biological reactor for oily sewage treatment is also presented.
