不同腐熟剂接种下肉牛粪污腐熟进程的比较研究

通过肉牛粪污好氧堆肥发酵,对接种不同腐熟剂与空白处理堆肥过程进行物理化性质分析比较,研究不同腐熟剂接种对堆肥过程的影响。结果表明：向堆肥物料中添加腐熟剂可加快堆肥升温速度,提高水分散失率、有机质降解速率,加快粪污腐熟进程,缩短堆肥周期;自主研发腐熟剂和市售腐熟剂堆肥效果相似,项目组自主研发腐熟剂具有加速肉牛粪污腐熟进程的功效。

Comparative Study on Composting Process of Beef Cattle Manure by Using Different Decomposing Inoculants

In order to assess the effects of different decomposing inoculants on the aerobic composting process, the physical properties of composting product of beef cattle manure treated with different decomposing inoculants were compared and analyzed. The results showed that the addition of decomposing inoculants to composting materials accelerated the speed of composting, increased water loss rate and degradation rate of organic matter, speeded up the process of manure decomposing, and shortened the composting cycle. The self-developed decomposing inoculants had the similar effects with the commercially available decomposing inoculants. The developed decomposing inoculants has the effect of accelerating the composting of beef cattle manure.
