【摘要】 以实际生活污水为进水,在实验室对连续流A/O除磷系统进行了聚磷菌的驯化与培养,当系统对磷的去除率稳定在95%以上时利用烧杯批式试验考察了合成污水与实际污水中聚磷菌的厌氧代谢过程,并基于生物除磷的Murnleitner代谢模型,根据试验数据推求了表征聚磷菌厌氧代谢特性的化学计量参数及反应速率。结果表明,合成污水与实际污水中聚磷菌厌氧代谢过程生成的聚β羟基链烷酸的成分及反应速率存在显著差异,研究结果对采用活性污泥数学模型准确模拟实际污水中的生物除磷过程具有一定的参考价值。更多还原

【Abstract】 Domestication and cultivation of PAOs were carried out in the lab of the phosphorus removal anaerobic/aerobic(A/O) unit using living sewage as influent.When the removal rate of phosphorus steadies at above 95%,batch tests were carried out to investigate different anaerobic metabolic characteristics of PAOs in synthetical and real sewage.Moreover,based on the Murnleitner metabolic model,stoichiometric parameters and reaction rate involved in anaerobic process were determined and compared.Results showed that the component of PHA and reaction velocity are evidently different in the process of anaerobic metabolism when the influent is real sewage and synthetic sewage.The results can be useful for the activated sludge mathematical model to accurately simulate phosphorus removal process with real sewage.更多还原
