| 摘 要： | 从运行稳定的SBR反应池好氧末端的活性污泥中分离筛选出1株高效聚磷菌LB4,结合生理生化特征分析和16S rDNA分子生物学技术,鉴定该聚磷菌为鲍曼不动杆菌(Acinetobacter baumannii);以EBPR工艺过程为载体,模拟将来可能采用的含可利用碳源的工业废水作为进水,探讨了不同营养条件下菌株LB4的除磷行为,初步分析了其代谢机理,研究表明:菌株LB4除磷的最佳温度为30℃、最适pH值为7.0,微量元素的有无对该菌株的除磷效能影响不大,提高生物除磷系统除磷效率的关键是提高厌氧释磷量.

| Abstract: | A strain LB4,with a high capability of accumulating phosphate,was isolated from activated sludge of sequencing batch reactor. The strain was identified as Acinetobacter baumannii in terms of its morphological and physiological features by 16S rDNA sequence analysis. The phosphate-accumulating effects of strain LB4 were studied with industrial wastewater under different nutritional conditions according to the enhanced biological phosphorus removal process,and the metabolic mechanism of strain LB4 was also an... |
