The invention discloses acinetobacter sp. and a preparation method of an acinetobacter sp. agent. According to the technical scheme, the provided acinetobacter sp. Y[3] is collected in the China Center for Type Culture Collection (CCTCC) on September 25, 2013, has a collection number of CCTCC NO:M2013445 and is heterotrophic nitrification bacteria; the acinetobacter sp. agent is prepared by inoculating the acinetobacter sp. Y[3] into a nitrification culture medium and fermenting for enlargement culture. The preparation method of the agent is simple and easy for large-scale production. The acinetobacter sp. can smoothly have a nitrification reaction in higher-concentration phenol-containing industrial wastewater and have simultaneous nitrification and denitrification reactions by taking phenol as a carbon source to convert ammonia nitrogen and organic nitrogen into nitrogen gas without nitrite nitrogen accumulation, achieves simultaneous efficient degradation of ammonia nitrogen and phenol in the wastewater, and has a good application prospect in the biological denitrification process of the phenol-containing industrial wastewater. |
