| 摘 要： | 本论文对好氧反硝化菌株FR2，FX5，FW4在好氧条件下的反硝化特性进行了研究。结果表明：反硝化主要发生在菌体的对数生长期，且反硝化过程中NO2^--N有少量的积累。
对不同温度、pH、碳源对好氧反硝化作用的影响进行了研究，结果表明：该三株菌在好氧条件下均具有良好的反硝化效果；温度为25℃～30℃的中性和微碱性条件反硝化效果较好；以乙酸钠为碳源的反硝化效果最好，NO3^-N的去除率最高。以葡萄糖为碳源的反硝化效果最差，NO3^-N的去除率最低。

| Abstract: | The nitrogen pollution and caused eutrophication are concerned as one of main environmental problems all the world,and denitrogenation in water is becoming key and hot point of water pollution.The biological denitrogenation is referred to optimal disposal method.The features of anti-nitration of FR1,FX5 and FX4 under the aerobic condition are studied. |
