【摘要】 针对低温污水氨氮去除困难的问题，对耐低温菌Acinetobacter albensis X1的氨氮去除特性进行研究。菌株X1的氨氮代谢途径以同化作用为主，占比85.96%，同时少量氮通过异养硝化-好氧反硝化过程转化为气态氮。低温条件下菌株X1可以利用多种有机酸盐为碳源，在m(COD)/m(N)≥2.5时具有较好的NH4+-N去除性能。更多还原

【Abstract】 To solve the problem of difficult ammonium removal from low temperature wastewater, the ammonium removal characteristics of the cold-adapted bacterium Acinetobacter albensis X1 were investigated. The main ammonium metabolic pathway of strain X1 was assimilation, accounting for 85.96%. At the same time a small amount of nitrogen is converted to gaseous nitrogen by heterotrophic nitrification-aerobic denitrification processes. The strain X1 can use a variety of organic acid salts as carbon source at low temperature, and had good NH4+-N removal performance when the m(COD)/m(N) ≥2.5.更多还原
