摘要

In this study, the kinetics of biogas production was studied by performing a series of the laboratory experiment with air stripped poultry litter. Four kilograms of Raw Poultry Litter is mixed with water in the ratio 1:3, respectively, and loaded inside the digesters and the samples are compared with Air stripped Poultry Litter for a retention time of 21days. The modified Gompertz equation suitably construes the cumulative biogas produced as a function of time. From the kinetics of the system, it is inferred that the biogas production potential (A), maximum biogas production rate , and lag phase period () of Raw Poultry litter is 18.77 (l/kg of VS); 1.08 (l/kg of VS/day); 1.5days, respectively, comparing with Air stripped Poultry Litter of 22.05 (l/kg of VS); 1.30 (l/kg of VS/day); 1 day, respectively. These results show that biogas production can be enhanced efficiently by means of ammonia removal pre-treatment process.
