摘要(Abstract)：

采用厌氧颗粒污泥和实验室模拟产气,系统研究了超高效厌氧生物反应器的床层膨胀行为。以床层膨胀率、最大污泥量和最大泥水接触时间作为膨胀行为表征参数,分别建立了固定态、流化态和输送态行为模型,模型计算值与试验值吻合较好。固定态时,ul≤0.45mm·s-1,床层膨胀率为0,最大污泥量为4867mL(床层有效体积为7850mL),最大泥水接触时间逐渐逼近860s(HRT最大值为2222s);流化态时,0.45mm·s-16.88mm·s-1,颗粒污泥洗出床层。反应器高效稳定运行时,床层处于流化态,其床层膨胀率、最大污泥量和最大泥水接触时间分别逼近160%、1860mL和104s。

关键词(KeyWords)： 厌氧反应器;膨胀行为;流化态;固定态;输送态
