研究了上流式厌氧污泥床(UASB)反应器在不同温度和水力停留时间(HRT)条件下，采用聚乙烯醇凝胶载体处理低浓度废水的可行性。温度由35℃降至25℃，再降至15℃，水力停留时间由2.0h降至0.22h。在35℃、25℃和15℃时，CODM−3D−1、−3D−1和−3D−1的COD去除效率分别达到28 kg、16 kg和6 kg。
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 2.0h to 0.22h. The COD removal rate reached 28kg-CODm−3d−1at 35°C, 16kg-CODm−3d−1at 25°C, and 6kg-CODm−3d−1at 15°C. The COD removal rate was reduced by half for each temperature reduction of 10°C.
