摘　　要：为了满足GB 31570—2015《石油炼制工业污染物排放标准》的要求,需对污水处理系统进行改造,在现有流程后增设深度处理单元,实现总氮的达标排放。本试验采用了高效生物膜脱氮工艺对炼油污水处理场的出水处理开展实验,以期为后期污水处理系统提标改造工程提供关键设计参数。In order to meet the requirements of ＂Emission standard of pollutants for petroleum refining industry GB 31570-- 2015＂, the wastewater treatment system needs to be reconstructed, deep treatment units should be set up in the present pro- cess to meet the emission standard of total nitrogen. In this experiment, high efficiency of biofilm nitrogen removal process is applied to treat the effluent from oil refinery sewage treatment works, to provide key design parameters for the later improve- ment and reconstruction of wastewater treatment system.
