| 摘要: |
| 随着禽畜养殖集约化、规模化程度的不断提高，禽畜粪便带来的环境污染问题日益严重。禽畜粪便富含有机营养物和氮、磷、钾等无机元素，具有巨大的资源回收潜力。但禽畜粪便也含有大量的有机污染物、重金属和抗生素，若管理不善将会对自然生态和人类健康造成严重危害。本文主要针对禽畜粪便污染现状及主要处理手段(包括焚烧产热、气化技术、水热液化、水热炭化、厌氧消化、好氧堆肥和蚯蚓堆肥)进行系统剖析，充分讨论禽畜粪便肥料化、能源化和养分回收的技术瓶颈及发展前景，并简要讨论禽畜粪便处理技术在经济和环境层面的可持续性，拟为我国禽畜粪便的资源化利用及其研究方向提供参考。 |

| Abstract: |
| With the increasing intensification and scale of livestock breeding,the environmental pollution caused by livestock manure is becoming more and more serious.Livestock manure is rich in organic nutrients and inorganic elements such as nitrogen,phosphorus and potassium,and has great potential for resource recovery.However,livestock manure also contains a large amount of organic pollutants,heavy metals and antibiotics.If not well managed,it will cause serious harm to natural ecology and human health.In this article,the current situation of livestock manure pollution and the main treatment methods (including incineration heat production,gasification technology,hydrothermal liquefaction,hydrothermal carbonization,anaerobic digestion,aerobic composting and vermin-composting) were systematically analyzed.The technical bottlenecks and development prospects of fertilization,energy utilization and nutrient recovery of livestock manure were fully discussed,and the sustainability of livestock manure treatment technology at the economic and environmental levels was briefly discussed.It is intended to provide reference for the resource utilization and research direction of livestock manure in China. |
