畜禽粪便中残留抗生素对厌氧消化影响的研究进展

厌氧消化技术处理畜禽粪便,既可以减少环境污染,又能够实现废物无害化、资源化。但畜禽粪便中残留的抗生素对厌氧菌的活性有很大影响,进而影响厌氧消化效果。目前含抗生素类畜禽粪便的厌氧消化处理的可行性受到广泛关注。概述了抗生素在畜禽养殖业中的应用现状和潜在危害,分析了抗生素对厌氧消化产气效果和微生物种群的影响及抗生素的厌氧降解情况,并对今后的研究重点和研发方向提出建议和展望,以期为含抗生素类畜禽粪便厌氧消化处理提供理论支持。

Research Progress on Effect of Antibiotic on Anaerobic Digestion Treatment in Animal Manure

Anaerobic digestion, one of the major methods for animal manure stabilization, can not only reduce environmental polution, but also realize resources recovery and wastes without harm. However, veterinary antibiotics are residue in animal manure, and some antibiotics have effects on the activity of anaerobic bacteria, and performance of anaerobic digestion. Nowadays, the feasibility of anaerobic digestion for animal manure contained antibiotic is arousing wide attention. This paper introduced the application status and potential hazards of antibiotics in livestock and poultry breeding; analyzed the effect of antibiotic on biogas production and microbial population; discussed the transfer and removal of antibiotic during the anaerobic digestion treatment; and put farward suggestion for future research focus and R & D direction, so as to provide theoretical support for anaerobic digestion treatment of antibiotic in animal manure.
