The charicaristics of anaerobic fermentation was studied on corn stalk mixed with fruit pulps in different ratio at 38℃. The results showed that biogas production increased with the rising of fruit pulps ratio in certain scope during fermenting in 50 days, but the methane content decreased in biogas. The optimum ferment ratio of fruit pulps to corn stalk was 2:3 (TS ratio 0.11, VS ratio 0.12), the total TS concentration was 10.85%. The methane content in biogas production was 51.22%. |
