一、前言炼厂含油污水的水质随加工原油的性质、加工工艺的不同和企业管理水平而有很大的差异,这种差异就带来了采用同一处理工艺(隔油、浮选、曝气)而产生出不同的处理效果。甚至同一炼厂由于水质的变化,处理后水质也时好时坏波动较大。为了更有效地利用现有处理设施,充分发挥它们的效能,达到稳定运行,就必须深入了解油在水中乳化状况及找出影响乳化稳定性的主要因素,在生产过程及管理 I. Preface The refinery oily wastewater quality varies greatly with the nature of the crude oil being processed, the processing technology and the level of enterprise management. Such differences result in the use of the same treatment process (oil separation, flotation, aeration ) And produce a different treatment effect. Even the same refinery due to changes in water quality, water quality after treatment is also good times and volatility. In order to make more efficient use of the existing treatment facilities, give full play to their effectiveness, to achieve stable operation, it is necessary to understand the oil emulsion in water conditions and identify the main factors affecting the stability of emulsification in the production process and management
