摘要
研究了改性厌氧混合折流板(MAHB)生物反应器在1、2、3和4 g COD/ l .d的不同有机负荷下处理造纸废水(RPME)的性能。生物反应器以1天的恒定水力停留时间(HRT)连续运行，不回收废水，不调整/添加化学品。在70天的运行过程中，达到了97%的化学需氧量(COD)和98%的挥发性脂肪酸的最高去除率，沼气产量为12.51 L/天，相当于甲烷(CH4)的产量为0.108L CH4/ g COD, pH系统稳定在6.6 ~ 7.2之间。此外，生物反应器系统的碱度显示出稳定的特征，表明整个系统得到了很好的缓冲，挥发性固体(VS)的降解率高达18%。这些结果表明，MAHB生物反应器在不同的OLR条件下成功地处理了RPME。
Performance of Modified Anaerobic Hybrid Baffled (MAHB) bioreactor treating recycled paper mill effluent: Effects of organic loading rates
The performance of modified anaerobic hybrid baffled (MAHB) bioreactor treating recycled paper mill effluent (RPME) was investigated at various organic loading rates (OLR) of 1, 2, 3 and 4 g COD/ L.day. The bioreactor was operated continuously at constant hydraulic retention time (HRT) of a day without effluent recycled and chemicals adjustment/addition. Throughout 70 days of operation, a maximum removal efficiency up to 97% of chemical oxygen demand (COD) and 98% of volatile fatty acid, biogas production of 12.51 L/day equivalent to methane (CH4) yield of 0.108L CH4/ g COD and a stable pH system between 6.6 to 7.2 were achieved. Additionally, alkalinity of the bioreactor system shows a stable profile that indicates the whole system was well buffered with a quit high degradation of volatile solid (VS) up to 18%. These results indicated that MAHB bioreactor has been successfully treated RPME at various OLR.
