禽畜粪便资源化利用技术

The Utilization Technologies of Poultry and Animay Feces as Nature Resources

大规模、集约化养殖业的发展,导致禽畜粪便的大量排放,使得其成为影响土壤、水体、大气和生物的污染源,限制了养殖业的发展,严重破坏生态环境及人类健康。目前针对畜禽粪便污染,从三个方面着手进行处理:源头控制技术、饲养过程控制技术和末端治理技术。畜禽粪便有巨大的资源发展潜力,其转化为资源,进行再利用,变废为宝。现在已经发展的比较成熟的畜禽粪便资源化技术有肥料化技术、饲料化技术和能源化技术,分别对其进行介绍。

The development of large-scale and intensive farming industry leads to a large number of livestock manure emissions and becomes the pollution sources of soil,water,atomosphere and biology.It limits the the prosperity of farming industry and severely damages the ecological environment and human health.At present,for the livestock and poultry manure pollution,it deal with from three aspects：the source control technology,control technology in the process of feeding and the end govern technonlogy.Livestock an poultry manure has great potential for resources development and can convert into resources conduct re-use and turn waste into treasure.Nowadays there are some developed and mature technologies as nature resources for poultry and animal feces.
