| 摘 要： | SBR是序批式活性污泥法的简称, SBR系统行运行模式不同,脱氮除磷效果会发生变化。SBR系统氨氮硝化过程在好氧阶段进行,脱氮过程主要在缺氧阶段进行。除少数细菌能进行自养反硝化,大部分反硝化细菌进行反硝化都是进行异养反硝化。经研究发现SBR运行过程中TN浓度和COD浓度具有相关性,COD和TN浓度之间存在三阶函数关系,本实验反硝化速率为1.2mg/L。

| Abstract: | SBR is the abbreviation of sequencing batch reactor, SBR system runs in different modes, and the effect of nitrogen and phosphorus removal will change. Nitrogen nitrification in the SBR system was carried out in aerobic stage, and the nitrogen removal process was performed during the anoxic phase. In addition to a small number of bacteria can carry out aerobic denitrification, denitrification of most of the denitrification bacteria are carried out heterotrophic denitrification. The study found that the denitrification process in the concentrations of TN and COD is correlated, between the concentrations of COD and TN are function of third order relation. , and the denitrification rate was 1.2mg/L. |
