摘要:

抗生素抗性基因(antibiotic resistance genes,ARGs)污染已经成为一个严重的环境问题。高温堆肥是一项高效、绿色的有机固废无害化处理方式,促进物质循环利用,减少抗生素及其ARGs的排放,但是传统高温堆肥具有发酵周期较长、无害化不彻底、消减ARGs和移动遗传元素效果较差等局限性,超高温堆肥(ultra-high temperature composting, UHTC)是近年来开发的一种有机固体废弃物资源化新技术,其具有发酵温度高、周期短、无害化效果强、资源化效率高和运行成本低等特点。然而,不同UHTC系统在去除有机固体废弃物中的ARGs效果仍存在显著差异,值得深入讨论及总结。因此,本研究对UHTC技术对有机固体废弃物中ARGs的降解效果及机制进行了深入探讨,旨在进一步加强为有机固体废物中ARGs控制提供理论支持。

Abstract:

The pollution of antibiotic resistance genes (ARGs) has become a serious environmental problem. High temperature composting is an efficient and green harmless treatment method for organic solid waste, which promotes the recycling of substances and reduces the emission of antibiotics and ARGs. However, traditional high temperature composting has some limitations such as long fermentation cycle, incomplete harmless treatment, and poor effect on reducing ARGs and mobile genetic elements. Ultra-high temperature composting (UHTC) is a new technology for recycling organic solid waste developed in recent years. It has the characteristics of high fermentation temperature, short cycle, strong harmless effect, high recycling efficiency and low operating cost. However, different UHC composting systems still have significant differences in the removal of ARGs from organic solid waste, which is worthy of further discussion and summary. Therefore, the degradation effect and mechanism of ultra-high temperature composting technology on ARGs in organic solid waste were discussed in this paper, aiming to further strengthen the theoretical support for the control of ARGs in organic solid waste.

Key words: antibiotic resistance gene, organic solid waste, ultra-high temperature compost
