In this study, the effects of organic loading rates (OLRs) on anaerobic fermentation of food waste were comprehensively evaluated using a hollow fiber type anaerobic membrane bioreactor (HF-AnMBR). Compared to other OLRs, biogas production rate was highest at the OLR of 9.72 g-COD/L/d, the organic matter removal efficiency was also significantly higher and VFA was in lower concentration. COD conversion efficiency was as high as 92.9%, 85.3%, 82.6% and 80.4% at OLRs of 2.43, 4.86, 7.29 and 9.72 g-COD/L/d, respectively. The major membrane fouling was caused by organic pore blocking, accounting for 59.6% of the total hydraulic resistance after long-term operation. The performance of HF-AnMBR was compared with a continuously stirred tank reactor (CSTR) and a self-agitated reactor (SAR). The higher operation OLRs, COD conversion efficiency and better effluent quality achieved by the HF-AnMBR are evidences of a significant improvement in reactor performance compared to CSTR and SAR.
