Studies on bench scale reactor were undertaken to determine its performance at various organic loading rate (OLR) and hydraulic retention time (HRT). The results indicated BOD and COD removals in the range of 67.2-77.4% and 57.8-69.1% respectively at the OLRs between 0.84 and 2.5 kgCOD/m3 d and HRT of 10 days. Daily gas production was measured by gas flow meter. Daily gas production varied between 0.268 and 0.326 m3/kgCOD added at the different OLRs. Studies were also carried out at lower HRT of 5 days. But BOD/COD removals reduced and correspondingly gas production also reduced. Gas composition remained constant at both the HRT and the Methane content was around 65-68% while the CO2 was around 32-35%. This paper discusses in detail the feasibility of upflow anaerobic fixed film fixed bed (UAFFFB) reactor system in treating the strong spent broth from the antibiotic industry.
开展了实验室规模反应器的研究,以确定其在不同有机负荷率(OLR)和水力停留时间(HRT)下的性能。结果表明,在OLR为0.84至2.5 kgCOD/m³·d且HRT为10天的情况下,BOD和COD去除率分别在67.2 - 77.4%和57.8 - 69.1%的范围内。每日产气量通过气体流量计测量。在不同的OLR下,每日产气量在0.268至0.326 m³/kgCOD添加量之间变化。还在5天的较低HRT下进行了研究。但BOD/COD去除率降低,相应地产气量也减少。在两种HRT下气体组成保持恒定,甲烷含量约为65 - 68%,而二氧化碳约为32 - 35%。本文详细讨论了上流式厌氧固定膜固定床(UAFFFB)反应器系统处理抗生素行业强废液的可行性。
