| 摘 要： | 为了考察水力停留时间(HRT)对炭纤维载体固定床厌氧反应器运行效果的影响,在进水COD分别为20 000~25 000 mg/L和40 000~45 000 mg/L2个浓度范围下,研究了不同HRT对反应器运行效果的影响。结果表明,通过HRT的调整,在达到相同有机负荷(OLR)下,进水COD为20 000~25 000 mg/L的COD去除率和产气量,明显比进水COD为40 000~45 000 mg/L的运行效果好;进水COD为20 000~25 000 mg/L,HRT为14 h,相应的OLR为41.09 kgCOD/(m3.d)时,COD去除率仍然维持在68%以上,沼气容积产气率达到14.55 m3/(m3.d)。炭纤维载体固定床厌氧反应器具有较高的COD去除率、产气效率以及抵抗低pH、高负荷冲击的能力,运行过程中没有发生反应器堵塞的现象。 |

| Abstract: | An anaerobic fixed-bed reactor packed with carbon fiber as carrier was designed and its performance was evaluated at various hydraulic retention times.The objective was to find the optimal concentration of influent chemical oxygen demand(COD) and hydraulic retention time(HRT) for treating sewage.The results demonstrated that the performance of influent COD range between 20 000 and 25 000 mg/L was markedly better than that of influent COD range between 40 000 and 45 000 mg/L,however,the organic loading rate(... |
