摘要：

A modified anaerobic baffled bioreactor (MABR) was studied under steady-state conditions for treating palm oil mill wastewater. Methane gas production was in the range of 0.32-0.42 1-CH4 (g-COD)(-1) removal, which corresponded to the methane content of 67.3-71.2% within the range of examined hydraulic retention time (HRT) of 3-10 days. The removal ranges of COD and grease/oil were from 87.4 to 95.3% and from 44.1 to 91.3%, respectively. The total volatile fatty acid production was 1450 mg l(-1) at HRT of 3 days and gradually decreased to 608 mg l(-1) at HRT of 10 days. Based on the experimental data, a kinetic model was discussed. Through the model the biokinetic parameters were evaluated, which represented the behavior of reactor very well. (C) 2001 Elsevier Science B.V. All rights reserved.
