摘要
肉羊养殖规模逐年扩大,粪尿及废弃物也成倍增加,如处置不当,易导致严重的污染。粪便经有机厌氧分解,产生有毒恶性及有强烈刺激味道的恶臭气体,包含一氧化碳、粪臭素、氨气等,易污染空气。此外,在养殖过程中,通常添加大量锌、铜、锰等微量元素,这些微量元素在肉羊体内消化利用率较低,多混合在粪便中排放,极易造成水体富营养化。肉羊粪便中还含大量寄生虫、虫卵、病原微生物等,若污染水源,会将这些病原传染给其他健康羊群,危害周围养殖。该文主要论述肉羊养殖场废弃物综合利用技术。
The scale of mutton sheep breeding has been enlarged year by year,and the amount of excrement,urine and waste has also been doubled.Organic anaerobic decomposition of feces,resulting in toxic and strong odor odor,including carbon monoxide,fecal odor,ammonia,etc.,easy to pollute the air.In addition,micronutrient such as zinc,copper and manganese are usually added in large quantities during the breeding process.These micronutrient have low digestibility in the body of mutton sheep and are often mixed in the faeces to cause Algal Bloom.Sheep feces also contain a large number of parasites,eggs,pathogenic microorganisms,if the pollution of water,these pathogens will be transmitted to other healthy sheep,harm the surrounding breeding.This paper mainly discusses the technology of comprehensive utilization of waste from mutton sheep farm.
