| 摘 要： | 温度与A2/O工艺处理功能密切相关,研究温度变化对系统脱氮效果产生的影响。试验结果表明:温度介于14.5℃～25℃范围内,COD去除率由70%上升至81.4%,温度介于25℃～34.3℃范围内,COD去除率最高达到85%以上,可保证COD稳定和高效的去除效果;最佳脱氮温度范围约为25℃～30℃之间,TN去除率约70%,硝化率达95%,过高或过低的温度条件对脱氮功能均有抑制作用。

| Abstract: | The temperature and functions of A~2/O process were closely related. Influence of temperature variation on nitrogen removal was studied. Results showed that COD removal rate would rise from 70% to 81.4% when temperature changed from 14.5℃ to 25℃ while COD removal rate was up to 85% when temperature changed from 25℃ to 34.3℃ ,. with removal rate stable and efficient. Under the temperature range of 25～30℃ which was the best for denitrification, the removal rate of TN was about 70% and nitrification could reach to 95%. Too high or too low temperature could inhibit function of nitrogen removal. |
