【摘要】 通过改变生物除磷脱氮工艺 SBR(A/ O/ A/ O)的运行参数 ,对其缺氧段进行研究 ,发现 :进入缺氧段的聚磷菌体内的 PHB是否充足 ,是缺氧吸磷现象是否明显的关键。在 SBR的缺氧段也存在反硝化吸磷现象 ,此反应装置的活性污泥中含有大量的可利用 NO3- 作为电子受体 ,进行缺氧反硝化吸磷的反硝化聚磷菌 (DPB)更多还原

【Abstract】 The paper studied the anoxic phase of the sequencing batch reactor (A/O/A/O) in different operations.The experimental results showed:The key for the phenomenon of denitrifying dephosphatationis was that there was enough stored PHB when polyP organisms enters anoxic phase.The phenomenon of denitrifying dephosphatation in anoxic phase of SBR(A/O/A/O) showed:In the sequencing batch reactor,there were a lot of denitrifying phosphorus removing bacteria(DPB),which can use nitrate as an electron acceptor to denitrify phosphate uptake in anoxic phase.更多还原
