Abstract:Municipal solid waste from Wuzhou was sampled and its composition and biochemical characteristics were analyzed. The effect of three different substrate concentration (TSr=20%, 25%,30%) on batch anaerobic digestion was investigated at mesophilic temperature[(35+2)℃]. The experiment results showed that all three digestions were stable with no inhibition of volatile fatty acids and ammonia. The pH was stable at 7.0~7.8 without control. The cumulative methane productions were 93.06, 105.92 and 117.23 L/kgVS for TSr of 20%, 25% and 30% respectively. Lower total solids concentration could help reduce the anaerobic fermentation period, while higher concentration could increase the methane yield.
