| 摘 要： | 目的研究碳源浓度变化对同步反硝化聚磷的影响。方法采用厌氧/缺氧/好氧方式运行的SBR反应器。结果相对于不同C/P与C/N值,分别得到相关释/聚磷和反硝化速率;在C/P值大于23,C/N值大于5的条件下,SBR系统对磷、氮及碳的去除率在90%以上,其中通过反硝化聚磷去除磷的比重高达60%~70%。结论在进一步提高C/P,C/N值条件下,碳源浓度的变化对释磷、聚磷速率的影响不显著,但对反硝化速率的影响相对明显。

| Abstract: | Aim To make a study on research to examine the influent COD concentration effects on biological denitrifying dephosphatation.Methods Denitrifying phosphorus removal was verified in a laboratory anaerobic/anoxic/ aerobic sequencing batch reactor(SBR).Results The rate of phosphorus release/uptake and the rate of denitrification were got respectively under different C/P ratio and C/N ratio condition;the experimental results showed that SBR have presented nitrogen,phosphorus,and carbon removal efficiencies were more than 90%,and the range of simultaneous denitrifying dephosphatation is more than 60%~70%.Conclusion Under the condition of C/P>23 and C/N>5,the rate of phosphorus release/uptake have no significant change responsible for increase of C/P ratio and C/N ratio,but rate of denitrification has noticeable change about it. |
