玉米秸与鸡粪混合厌氧消化产气性能与协同作用
Performance and synergistic effect of anaerobic co-digestion of corn stover and chicken manure
摘要
Abstract
Performance and synergistic effect of anaerobic co-digestion of corn stover and chicken manure were investigated. Nine ratios of corn stover to chicken manure ( CS/CM) (1:0,1: 1,1:2,1:3,1:4,2: 1,3: 1, 4:l,and 0: 1)) and three loading rates of total solids (TS) (50, 65 and 80 g/L) were used. The results showed that compared to co-digestion of untreated corn stover and chicken manure, 5. 5% ～ 62% more biogas productions were obtained for co-digestion of NaOH pretreated ones. The co-digestion with CS/CM of 1: 2 and loading rate of 50 g TS/L obtained the highest total methane production of 19 488 mL, which was 32. 6% and 11.4% higher than that of the CS/CM ratios of 1:0 and 0: 1 at the same loading rate. The synergistic effect of co-digestion of chicken manure with NaOH pretreated corn stover contributed to methane yield increase of 7. 1% ～ 17. 7% . The synergistic effect of the co-digestion with CS/CM of 1: 2 was 25% ～ 150% higher than other radios. This study would provide the parameters for effective operation and optimal design of anaerobic co-digestion facility of straw and manure.关键词
