The feasibility of treating low-strength wastewater with an up-flow anaerobic sludge blanket (UASB) reactor, using a poly(vinyl alcohol)-gel carrier, at various temperatures and hydraulic retention times (HRTs) was examined. The temperature was decreased from 35°C to 25°C and then to 15°C. The HRT was reduced from 2.0 h to 0.22 h. The COD removal rate reached 28 kg-COD m(-3)d(-1) at 35°C, 16 kg-COD m(-3)d(-1) at 25°C, and 6 kg-COD m(-3)d(-1) at 15°C. The COD removal rate was reduced by half for each temperature reduction of 10°C.
采用聚（醇）-凝胶载体，在不同温度和水力停留时间（HRT）条件下，用上流式厌氧污泥床（UASB）反应器处理低浓度废水的可行性进行了研究。温度从 35°C 降低到 25°C，然后降低到 15°C。水力停留时间从 2.0 h 降低到 0.22 h。在 35°C 时，COD 去除率达到 28 kg-COD m(-3)d(-1)，在 25°C 时为 16 kg-COD m(-3)d(-1)，在 15°C 时为 6 kg-COD m(-3)d(-1)。每次降低 10°C，COD 去除率降低一半。
