摘要
畜禽养殖业快速发展的同时伴随着抗生素的大量使用,因抗生素不能被机体完全代谢而通过粪尿排出,粪尿中积累的抗生素通过多种途径进入环境,从而引起抗生素残留及耐药性问题,并对人畜健康及生态环境造成潜在威胁,因此有效去除环境中的抗生素至关重要.而去除抗生素不仅要注重降解效果,也要注意二次污染、降解成本等问题.本文介绍了养殖环境中抗生素与抗性基因来源及传播途径,重点阐述了现有的抗生素降解方法、原理和特点,包括物理吸附法、高级氧化技术及生物降解,并对现存抗生素污染问题提出建议,以期为抗生素高效降解提供参考.
Abstract
The rapid development of livestock and poultry farming is accompanied by the massive use of antibiotics which are excreted through feces and urine because they cannot be completely metabolized.The accumulated antibiotics in feces and urine enter the environment in various ways,thus leading to problems as antibiotic residues and drug resistance.It poses potential threats to human and animal health and the ec-ological environment,so it is important to effectively remove antibiotics from the environment.However,the removal of antibiotics should not only focus on the degradation effect,but also on secondary pollution,degradation costs and other issues.This paper introduces the sources and transmission of antibiotics and resistance genes in the breeding environment,and highlights the existing methods,principles and charac-teristics of antibiotic degradation,including physical adsorption,advanced oxidation technology and bio-degradation.It also proposes suggestions on the current antibiotic contamination problems in order to pro-vide reference for efficient antibiotic degradation.
