摘要：

厌氧膜生物反应器（AnMBR）将膜与厌氧生物处理技术相结合，能够有效降解有机物并兼顾能量回收，成为一种新兴污水处理技术。然而由于AnMBR低温下生物降解效率不高，造成膜污染加剧，从而限制了其推广应用。本文对比研究了低温下（10°C）添加纤维束填料与否的两个平行的分置式厌氧膜生物反应器(AnMBR)在不同水力停留时间（HRT）下的COD去除效果、产气能力以及膜污染行为。结果表明：投加填料的B-AnMBR在不同的HRT下均能保持高效而稳定的COD去除率，产气量提升43%，而且甲烷含量增长26%~42%。由于COD去除效果好，B-AnMBR中膜污染显著缓解，在HRT = 12 h或8 h下运行时间延长近一倍。

Anaerobic membrane bioreactor (AnMBR) combines membrane with anaerobic biological treatment technology, which can effectively degrade organic matter and take into account energy recovery. It has become a new sewage treatment technology. However, due to the low biodegradation efficiency of AnMBR at low temperature, the membrane fouling is aggravated, which limits its application. In this paper, the COD removal efficiency, gas production capacity and membrane fouling behavior of two parallel split anaerobic membrane bioreactors (AnMBR) with or without fiber bundle filler at low temperature（10 °C）were compared and studied under different hydraulic retention times (HRT). The results show that B-AnMBR with filler can maintain efficient and stable COD removal rate under different HRT, gas production increases 43%, and methane content increases 26%~42%. Due to the good COD removal effect, the membrane pollution in B-AnMBR is significantly alleviated, and the running time is nearly doubled at HRT=12h or 8h. The research results will provide a reference for the effect of AnMBR filler and the selection of suitable HRT and other operating conditions under the actual low temperature operation.
