摘　　要：国内部分炼化企业应用曝气生物滤池(BAF)作为炼油污水深度处理工艺的主体技术,但在实际运行中处理效果存在一定差异。通过统计、比较各炼化企业污水深度处理的相关情况,分析了深度处理工艺中预处理的作用及对BAF的影响、设备运行情况及选型、后处理单元系统配置与回用方向之间的关系及工艺选择等。经比较,认为若回用于循环水,建议系统配置为"溶气气浮机/高密度沉淀池+BAF+过滤+消毒",若回用于除盐水,建议系统配置为"溶气气浮机/高密度沉淀池+臭氧+BAF+过滤+UF-RO+消毒"。Currently, some refinery enterprises in China apply BAF as the main technology of sewage advanced treatment system. However, in actual operation, there are some differences in treatment effect. Through the statistics and comparison on the relevant advanced sewage treatments taken by refinery enterprises. The paper briefly analyzes the function of the preprocessing in the advanced treatment and its influence on BAF, the operation of the equipment, the model selection, the relation between the post-processing system configuration and the recycling direction as well as the technological selection.
