| 摘 要： | 在2个序批式反应器中,研究了废水中常见的两种挥发性脂肪酸乙酸、丙酸对于AEI强化生物除磷的影响。结果表明,短期的驯化中,R1的除磷效果优于R2,两者去除率为75.5%和61.8%。随着驯化的进行,R2的除磷效果提升。48～96 d,R1和R2的去除率为76.95%和92.1%。两者除磷效率的高低与微生物体内聚磷水平密切相关。静置期,R1和R2有明显释磷现象。

| Abstract: | To investigate acetate and propionate as carbon sources for phosphorus removal in the Aerobic/Extended-Idle regime（AEI）.After a period of sludge acclimation（20 d）,R1 showed a higher P removal efficiency than R1.The average efficiency of phosphorus removal in R1 and R2 were 75.5%and 61.8%respectively.However,after long-term acclimation（48 d） R1 P removal efficiency was improved.The average efficiency of phosphorus removal in R1 and R2 were 76.95%and 92.1%respectively.The P in the wastewater was converted to poly-P in this research,the more poly-P accumulating the P removal efficiency higher.In the idle phase,though obvious phosphorus release was observed in both R1 and R2. |
