摘要
在以牛粪为原料的厌氧发酵中,通过比较直接用水稀释牛粪和加入发酵20天的沼液然后再用水稀释牛粪的两个发酵组的COD去除率、总产气量等指标,研究结果发现,牛粪直接用水稀释发酵的效果比较好,总产气量比另一发酵组高出52.2%,COD去除率高出23.5%。
Through respectively analysis the pH, VFA, biogas production per day, COD removal rate and total biogas of the dairy manure liquids and swiging effluent in it as seeded materials ,the characterization of anaerobic fermentation of dairy manure is studied. the results showed that the dairy manure liquids fermentation is better , it’s total biogas production is 1.522 times to the other ones and it’s COD removal rate is 1.233 times to the other ones.
