畜禽粪便资源化利用研究进展

Research progress on resource utilization of livestock and poultry manure

规模化畜禽养殖业为社会带来巨大经济收益的同时,也带来了严重的环境污染问题。文章综合论述了我国畜禽粪便的污染现状,对近年来畜禽粪便无害化处理技术,包括肥料化技术、饲料化技术和能源化技术作了详细的论述,指出目前畜禽粪便资源化利用主要存在技术不够成熟,缺乏相应的政策支持等问题,并提出优化技术体系及加强环境保护立法的建议,为畜禽粪便资源化利用、减少环境污染提供参考。

Though mass livestock and poultry breeding brought magnificent economic benefits to the society, it made great harm to the environment. By reviewing the current status of environmental pollution caused by livestock and poultry manure in China, harm-free treatment technology for livestock and poultry manure including fertilization technology, feed processing technology and energy technology were elaborated so as to address the existing issues in this regard and provide references for resource utilization and eliminating environmental pollution through modified technical system and environ- ment laws.
