摘要
通过试验研究反硝化聚磷菌在厌氧-缺氧和厌氧-好氧2个不同SBR反应系统中达到了同步脱氮除磷的效果.这一结果说明A2SBR反应系统中的聚磷菌能够利用硝酸根代替氧作为最终电子受体.聚磷菌在A/OSBR中的聚磷速率是30-70 mg P/gMLVSS.h,在A2SBR中是15-32 mg P/gMLVSS.h.
In this study, denitrifying phosphate-accumulating bacteria achieved complete phosphate removal effect in two different systems： an anaerobic-anoxic sequencing batch reactor and an anaerobic-aerobic sequencing batch reactor. This result showed that phosphate-accumulating bacteria in the A2 SBR could use nitrate as terminal electron acceptor instead of oxygen. Phosphate-accumulating bacteria accumulates phosphate with a rate between 30 and 70 mg P/gMLVSS h in the A/O SBR and between 15 and 32 mg P/gMLVSS h in the A^2 SBR.
