规模养猪废弃物资源化关键技术研究进展

Research Progress on the Key Technologies of Waste Recycling in Large Scale Pig Farm

规模化养猪的管理模式、经济效益等优于传统的散户养猪,但是养猪废弃物集中排放,使污染程度增加,处理难度增大,易导致严重的环境问题。养猪废弃物含高浓度有机污染物和氮磷,这些也是植物、动物以及微生物生长需要的主要营养物质,通过肥料化、饲料化、能源化等一系列的关键技术手段可将规模养猪废弃物进行资源化,变废为宝。

The management mode,economic benefits of large scale pig breeding are superior to that of the traditional private pig breeding,but the concentrative discharge of waste from large scale pig farms greatly pollutes the environment,which is hard to deal with and leads to worse environmental problems.The waste from pig farms contain high density of organic pollutants and N and P which are main nutrients for plants,animals,and microorganisms'growth.A series of key technologies can turn the waste into fertilizer,fodder,and energy,making waste a wealth.
