摘要
试验研究了不同负荷下不同混合比例的鸡粪与NaOH预处理麦秸的厌氧发酵产气性能和协同作用效果。以鸡粪和2%NaOH预处理后的麦秸作为发酵原料,研究了混合物料在3种负荷和9种混合比例条件下的厌氧发酵产气情况。结果表明:在3种负荷(50,65,80 g/L)中,均是鸡粪和麦秸比例为1∶2时产气效果最佳,其累计产气量分别达到32 000,43 030 mL和50 370 mL;其TS产气率分别达到328.2,356.9,352.8 mL/g,比纯鸡粪相应负荷分别提高了27%,29%,23%。不同比例下,3种负荷中,均是65 g/L时产气效果最好,鸡粪与麦秸的协同作用使累计产气量提高了7%～17.7%。
Biogas production and synergistic effect on anaerobic co-digestion of chicken manure and pretreated wheat straw with 2% NaOH was studied.Three loadings were tested, which were made by mixing chicken manure with pretreated wheat straw at different ratios.Biogas yield of the chicken manure and wheat straw ratios of 1：2 was the optimal in the three loading rates, and their cumulative gas yield achieved 32 000 mL,43 030 mL, and 50 370 mL when corresponding loading was 50,65,80 g/L,and the gas yield achieved 328.2,356.9,352.8 mL/g and increased by 27%, 29%, 23% compared to pure chiken manure.The loading of the best biogas performance was 65 g/L in the chicken manure and wheat straw ratios of 1：2,and cumulative biogas yield increased by 7%-17.7% due to the synergistic effect of chicken manure and pretreated wheat straw.
