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
