In this paper, the biodegradation of organic compounds in refinery wastewater was studied. Different microbial communities suitable for the treatment of refinery wastewater were selected to degrade the pretreated wastewater. The results showed that the degradation efficiency of COD and ammonia nitrogen was 59.4% and 56.7% respectively; the degradation efficiency of COD and ammonia nitrogen was 50.2% and 60.6% respectively. It can be used as the dominant bacteria for further domestication and cultivation of petrochemical wastewater biological treatment.
