摘要
采用厌氧-好氧SBR反应器(A/OSBR)处理含磷废水,研究不同温度条件下磷的转化过程及去除机理。结果表明,温度对总磷(TP)和总有机碳(TOC)的去除影响并不明显。TP的去除率均达到95%以上。这主要是由于反硝化除磷过程的发生。反应器中污泥胞内聚合物主要以PHB的形式存在,PHV和PH2MV含量相对较低。而温度对PHB在好氧阶段的消耗的影响并不明显。
The A/O SBR was used to treat the wastewater containing phosphorus, and the phosphorus transformation and removal mechanisms at different temperature were investigated. The results showed that the influences of temperature on TP and TOC removal efficiencies were insignificant, and TP removal efficiency reached above 95 % due to the occurrence of denitrifying phosphorus removal process. PHB was the dominant intracellular polymers in the reactor and the contents of PHV and PH2 MV were relatively low. The consumption of PHB at the aerobic stage in the reactor was not affected significantly by temperature.
