| 摘 要： | 采用两级SBR工艺(TSSBR)处理COD与氮浓度较高的工业废水,SBR1去除有机物,SBR2主要进行硝化反硝化。TSSBR与传统SBR工艺相比,COD降解速率和硝化反应速率明显提高,COD去除率由84%提高到93%,2种工艺的反硝化速率没有明显差别。在原水COD浓度较高的情况下,TSSBR可有效克服高COD浓度对硝化反应的抑制,硝化反应速率是传统SBR的2倍。对于COD和氮浓度较高的工业废水,TSSBR明显优于传统SBR,是一种理想的处理工艺。

| Abstract: | Industrial wastewater with high strength COD and nitrogen was treated in TSSBR system.Most of organic substrate was removed in SBR1 and nitrogen removal occurred in SBR2 via nitrification-denitrification.As compared to SBR,COD degradation rate and nitrification rate in TSSBR were increased obviously.COD removal efficiency was increased from 84% to 93% as compared to SBR,but denitrification rate of two processes was almost same.TSSBR avoided the inhibition of the high organic loading to nitrification and nitrification rate was two times of that in SBR under the high influent COD.For the treatment of industrial wastewater with high strength COD and nitrogen concentration,TSSBR is better than SBR. |
