利用微生物处理畜禽粪便的研究

Study on Animal Slurry Treatment by Microorganism

随着养殖业的快速发展,畜禽粪便大量堆积对环境的污染问题也日益严重。为了缓解环境和资源问题,将这些丰富的有机质资源化进行重新利用显得越发重要。阐述和总结了微生物资源对畜禽业发展的意义,特别是在畜禽粪便等废弃物处理上与微生物关系紧密。微生物在粪便除臭、有机质降解转化,甚至是通过调整饲料营养比例或改善饲料消化水平来降低禽畜粪便的生产量都起着重要的作用。因此,利用微生物来改善养殖业废弃物带来的污染问题以及资源化利用畜禽粪便具有广阔的应用前景。

With the dramatic development of livestock production,serious pollution issues caused by the disposal of animal slurry have arisen increasingly.It is of great importance to recover these organic matter resources in order to meet the needs of source and solve the environmental problems.And this paper reviews the significance of microorganism for livestock development and particularly the close relationship between microorganism and biodegradation of animal breeding residues.These bacteria play an important role in odor control,degradation and conversion of organic matters,and even the reduction of animal waste discharging amount by adjusting the feed nutrition proportion or improving the digestibility of nutrients.Consequently,it shows good application prospect of microbe practice in the improvement of contaminated environment resulting from livestock farming residues and the utilization of livestock manure resource.
