  • 摘要: 以新型固定化硝化菌活性填料为研究对象,以游离态硝化菌为参照,分别考察了各个环境因素对固定化硝化菌硝化活性的影响,确定了最佳操作点为温度30 ℃,pH 8.0~9.0,DO 4.0 mg/L。与游离态硝化菌相比较,硝化菌固定化后并没有改变其对温度的敏感程度;固定化硝化菌可在偏碱性环境下保持较高的硝化活性;DO对固定化硝化菌的硝化活性有较大影响,需要较高的DO值来保持较高的硝化速率。为考察固定化硝化菌活性填料连续处理氨氮废水的效果,采用最佳操作点进行了连续运行实验,实验共进行60 d。结果表明,新型固定化硝化菌活性填料抗冲击负荷能力强,硝化性能高效稳定,实验条件下最高硝化速率可达到86.45 mg/(L·h)。
    Abstract: With novel immobilization of nitrobacterium as the object of study, the effects of different factors on the nitrification activities of immobilized nitrobacteria were compared to that of free nitrobacteria. The ideal operational factors were observed to be temperature of 30 ℃, pH from 8.0 to 9.0, and DO of 4.0 mg/L. There was no difference in the sensitivity of the immobilized nitrobacterium to temperature change when compared to that of free nitrobacterium. In addition, immobilized nitrobacteria could sustain their higher nitrification activities even under mild alkali conditions. Furthermore, DO had a significant effect on nitrification activities of immobilized nitrobacterium, and high DO values were required to maintain a high rate of nitrification for the immobilized nitrobacterium. In our study, to test the impact of immobilized nitrobacterium as an active filler on ammonia-nitrogen wastewater, the immobilized bacteria were observed under optimal operational conditions for continuous 60 days of treatment. The results show that the novel immobilized nitrobacterium had a strong impulsion load resistance and stable and efficient nitrification activity; the highest rate of nitrification activity observed was 86.45 mg/(L·h).
