摘要： To enhance the codigestion of degradation and improve biomethane production potential, sugarcane bagasse and filter mud were pretreated by sodium hydroxide NaOH 1N at 100 degrees C for 15, 30, and 45 minutes, respectively. Biomethane generation from 1-liter batch reactor was studied at mesophilic temperature (37 +/- 1)degrees C, solid concentrations of 6%, and five levels of mixing proportion with and without pretreatment. The results demonstrate that codigestion of filter mud with bagasse produces more biomethane than fermentation of filter mud as single substrate; even codigested substrate composition presented a better balance of nutrients (C/N ratio of 24.70) when codigestion ratio between filter mud and bagasse was 25 : 75 in comparison to filter mud as single substrate (C/N ratio 9.68). All the pretreatments tested led to solubilization of the organic matter, with a maximum lignin reduction of 86.27% and cumulative yield of biomethane (195.8mL.gVS(-1), digestion of pretreated bagasse as single substrate) obtained after 45 minutes of cooking by NaOH 1N at 100 degrees C. Under this pretreatment condition, significant increase in cumulative methane yield was observed (126.2mL.gVS(-1)) at codigestion ratio of 25 : 75 between filter mud and bagasse by increase of 81.20% from untreated composition.
