| 摘 要： | 为考察填料式厌氧折流板反应器（CABR）处理分散式生活污水抗短期有机负荷冲击的稳定性,从宏观运行性能、中间产物累积以及微观微生物活性3个层次来研究不同温度下短期有机负荷冲击对CABR运行性能影响。结果表明：宏观运行性能指标TCOD沿程变化曲线在28℃时受到有机负荷冲击仍呈现＂L＂型,容积负荷去除率也由基准条件下0.27kg/（m3.d）提高至0.73 kg/（m3.d）,但随温度的下降,沿程曲线逐渐接近＂／＂型,容积负荷去除率的增加幅度也逐渐变小。中间产物积累指标中VFA/碱度比值小于0.11～0.14时,TCOD去除率可达80%以上;SMP/SCOD比值沿水流方向呈上升趋势表明CABR抗负荷冲击性能较佳。而微观微生物酶活性受基质浓度提高的促进效应和温度下降的抑制效应相互作用表现各异。总体而言,在高温（28℃）条件下,分散式生活污水的有机负荷冲击不会对CABR出水造成显著影响,但在中温（18℃）和低温（10℃）条件下,CABR抗有机负荷冲击的稳定性随温度的下降而下降。
