中文摘要: |
为考察羊粪与尾菜联合高固体厌氧消化性能,采用批式试验,在初始有机负荷为45 gVS·L-1和中温(37℃)的条件下研究羊粪与尾菜不同挥发性固体(VS)质量配比(1∶0、3∶1、2∶1、1∶1、1∶2、1∶3、0∶1)对厌氧消化性能的影响。结果表明:羊粪与尾菜在3∶1、2∶1、1∶1、1∶2、1∶3的不同配比处理条件下累积VS甲烷产率分别为181.6、158.7、194.2、184.6、197.2 mL·g-1 VS,与羊粪单独发酵处理相比,甲烷产率提高7.3%~33.3%,与尾菜单独发酵处理相比,厌氧消化迟滞期(λ)与达到最大VS累积甲烷产量90%所需的时间(T90)分别缩短3.2~5.8 d与2.8~5.4 d。联合厌氧消化协同效应分析表明,除2∶1处理外,羊粪与尾菜不同配比联合高固体厌氧发酵均存在协同作用。在中温高固体厌氧消化工程应用中,建议羊粪与尾菜VS配比为1∶1,设计水力停留时间为20 d,累积VS甲烷产率为194.2 mL·g-1 VS。 |
英文摘要: |
In order to investigate the effect of the mass ratio of sheep manure to vegetable residues on anaerobic digestion, high-solid anaerobic batch co-digestion of sheep manure and vegetable residues at 1:0, 3:1, 2:1, 1:1, 1:2, 1:3, and 0:1 ratios was carried out at 37℃ with initial organic loading of 45 g VS·L-1. The results showed that the cumulative methane yields based on volatile solids of sheep manure and vegetable residues at 3:1, 2:1, 1:1, 1:2, and 1:3 ratios were 181.6, 158.7, 194.2, 184.6, and 197.2 mL·g-1 VS, respectively, which increased by 7.3%~33.3% compared to that with only sheep manure as the substrate. Compared with only vegetable residues as the substrate, the lag periods of anaerobic digestion (λ)and the time to achieve 90% of the maximum cumulative methane yield (T90)were shortened by 3.2~5.8 d and 2.8~5.4 d, respectively. Synergistic effect analysis of the anaerobic co-digestion showed that synergistic effects existed between anaerobic co-digestion of sheep manure and vegetable residues at the different mass ratios, except for 2:1. For practical project application, a 1:1 substrate mixture of sheep manure to vegetable residues was recommended, as the designed retention time and cumulative methane yield based on volatile solids were 20 d and 194.2 mL·g-1 VS, respectively. |
