摘要：

Attempts were made to optimize bioprocess parameters for maximum production of methane and removal of chemical oxygen demand (COD) and biological oxygen demand (BOD) from black liquor in the process of biomethanation in three-phase fluidized bioreactor. The optimum hydraulic retention time (HRT) is 8 h and optimum initial pH of the feed was observed to be 7.5. The optimum feed temperature is 40 degrees C and optimum feed flow rate is 16 L/min at organic loading rate (OLR) of 45.158 kg COD.m(-3).h(-1) respectively. The maximum methane constitutes 64.82% (v/v) of the total biogas generation. The maximum biogas yield rate is 0.723 m(3)/kg COD.m(-1).h(-1) with methane yield rate of 0.530 m(3)/kg COD.m(-3).h(-1) respectively at optimum biomethanation parameters. The maximum COD and BOD remediation of the black liquor are 79.65% (w/w) and 81.54% (w/w) with maximum OLR of 11.686 kg COD.m(-3).h(-1) respectively.
