| dc.description.abstract | Young landfill leachate digestion was monitored for soluble organic matter removal and sulfide production in anaerobic batch reactors. COD removal kinetics and inborn sulfide inhibition pattern were determined according to extended Monod kinetics for product inhibition. The inhibition pattern suited noncompetitive inhibition model with a critical inhibitor concentration (K(i)) of 850 mg S(2-)/L. Kinetic constants k and K(s) were determined accordingly. Organic matter removal followed a second order reaction kinetics. The maximum dissolved sulfide production obtained was 450 mg S(2-)/L and COD removal proceeded at a range of 81-93% with a minimum level of 67-76% as a result of a drop in pH intensifying H(2)S toxicity. Organic loading rate was applied at values from 0.18 kg COD/m(3).d to 0.5 kg COD/m(3).d where increasing rates enhanced methanogenic activity and sulfide production was stabilized at a level of 100-130 mg S(2-)/L accordingly. Results showed that methanogenic activity ameliorated at higher OLRs indicating that they were also subject to competition for substrate as well as sulfide inhibition despite a high COD/SO(4) ratio. | en_US |
