摘要
文章为探究猪肉的资源化利用潜力,对新鲜购买的猪肉进行厌氧消化实验,分别以猪皮、猪瘦肉和猪脂肪为实验原料,实验温度为30℃,采用批量式发酵工艺,进行发酵产沼气实验。整个实验分别历时76 d,113 d和83 d,总产气量分别为13660 mL,18850 mL和14780mL,平均甲烷含量分别为64%,66%和63%,产沼气潜力分别为1139 mL·g~(-1)TS,1571 mL·g~(-1)TS和1231 mL·g~(-1)TS或1159 mL·g~(-1)VS,1687 mL·g~(-1)VS和1257 mL·g~(-1)VS。结果表明厌氧工艺可以很好地实现病死猪肉的资源化利用。
In order to investigate the potential of pork resource utilization, anaerobic digestion experiments of fresh pork were carried out under 30℃ adopting batch fermentation with pig skin, lean pork and pig fat as raw material respectively. The fermentation with different meat lasted for 76 d, 113 d and 83 d, respectively, the total gas production were 13660 mL, 18850 mL and 14780 mL, the average methane content were 64%, 66% and 63%, respectively. The biogas production potential were 1139 mL·g~(-1)TS, 1571 mL·g~(-1)TS and 1231 mL·g~(-1)TS, or 1159 mL·g~(-1)VS, 1687 mL·g~(-1)VS and 1257 mL·g~(-1)VS, respectively. The results showed that the anaerobic process could perfectly realize the resource utilization of diseased and dead pork.
