Abstract

Abstract:

A series of experiments using denitrifying phosphorus accumulating sludge cultivated in A/A SBR process have been carried out. The effects of SRT on denitrifying dephosphorization and COD removing results are studied. Through comparing the changes in different SRT sludge properties, the causes of different dephosphorization results militated are analyzed, and the relevance of SRT to sludge concentration and dephosphorization mechanism are discussed. The results show that the stably running denitrifying dephosphorization system in condition that it has no sludge discharge can work continuously for 36 days.

Key words: denitrifying dephosphorization, sludge retention time(SRT), poly-β-hydroxybutyrate(PHB), poly-P

摘要：

利用厌氧/缺氧SBR驯化成功的反硝化聚磷污泥进行试验, 研究了泥龄对反硝化除磷及COD去除效果的影响, 通过比较不同SRT污泥性质的变化, 分析产生不同除磷效果的原因, 探讨SRT与污泥浓度、除磷机制的关联性。结果表明:稳定运行的反硝化除磷系统在不排泥情况下, 最多可连续运行36 d。
