摘要

This study was carried out to assess the impact of organic loading rate (OLR) on the performance of mesophilic anaerobic baffled reactor (ABR) for H₂ production from a co-digestion of municipal food waste and kitchen wastewater. The reactor was operated at different organic loading rates (OLRs) of 29, 36 and 47 g COD_total/L d. The hydraulic retention time (HRT) was kept constant at 1.6 d. The results showed that increasing the OLR from 29 to 36 g COD_total/L d, leads to a significant (p 鈻?0.01) drop in the H₂ production from 6.0 卤 0.5 to 5.4 卤 1.04 L H₂/d, respectively. However, the H₂ production remained at the same level of 5.3 卤 1.04 L H₂/d at increasing the OLR from 36 to 47 g COD_total/L d. The H₂ generation was mainly due to conversion of COD (57%) and carbohydrate (81%). Protein and lipids conversion represents only 23.3%and 4.1%respectively for H₂ production.
