摘要: A semi-continuously mixed mesophilic tubular anaerobic digester was tested for the conversion of fruit and vegetable waste (FVW) into biogas. The effect hydraulic retention time (HRT) feed concentration on extent degradation examined. Varying HRT between 12 20 days had no fermentation stability pH remained 6.8 7.6, but an inhibition methanogenic bacteria observed at below days. overall performance reactor depressed by changing from 8% to 10% TS (dry weight). By applying a 6% in digester, 75% efficiency FVW biogas with methane content 64% achieved.
