| 摘 要： | 为系统考察厌氧水力停留时间（AHRT）对生物除磷效果的影响，本文以实际生活污水作为进水，在实验室连续流厌氧／好氧（A／O）除磷系统稳定运行的基础上，统计了不同AHRT下系统除磷效果及胞内贮存物的变化。设计批式实验，考察了AHRT较长情况下生物增强除磷代谢过程，针对实验过程中出现的厌氧聚羟基链烷酸酯（PHAs）分解和厌氧糖原合成现象，提出聚磷不足情况下聚磷菌代谢的假想模式。最后根据实验结果指出A／O除磷工艺AHRT的确定应以PHAs的合成量最大作为控制目标。

| Abstract: | Anaerobic HRT(AHRT) is a key factor of anaerobic-aerobic(A/O) unit for phosphorus(P) removal.In most cases,AHRT is determined empirically by designers.In this paper,the statistics of P removal,and changes of polyhydroxyalkanoates(PHAs) and glycogen content in P accumulating organisms(PAOs) under different AHRT were carried out on the basis of stable operation of lab continuous flow A/O P removal system to investigate the enhanced biological P removal metabolic process by a batch test.Anaerobic decomposition of PHAs and replenishment of glycogen were found during the test.To explain the above phenomenon,a new metabolic mode of PAOs was proposed. |
