玉米秸秆－牛粪不同配比对沼气产量的影响
Effects of Different Proportions of Maize Straw and Cow Manure on Biogas Production
摘要
Abstract
Four treatments including cow manure-maize straw at the ratio of 2∶1 ( A), cow manure ( B) , maize straw ( C) , cow manure-maize straw at the ratio of 1∶2 ( D) were set to study the effects of dif-ferent proportions of cow manure and maize straw on biogas production under anaerobic fermentation with the total solid (TS) concentration as 10% at (30 ±1)℃.The duration of this test was 55 days.The results showed that the total biogas yield of the treatments was in the order of A>D>B>C.The change of daily bio-gas yield and daily cumulative biogas yield had great differences between different treatments.The biogas peak of treatment A was present during 17~26 days, while that of treatment D was present during 22~23 days. The total biogas yield of treatment A and D was 6 997 mL and 6 842 mL respectively, which were higher than that of treatment B and C.In conclusion, the mixture fermentation of cow manure and maize straw could accel-erate biogas producing rate, improve biogas production status, and increase the biogas producing potential.关键词
