摘要: 厌氧消化是畜禽粪污资源化、无害化及减量化处理的主流技术,重金属、抗生素和抗性基因是畜禽粪污中存在的典型污染物。本综述围绕厌氧消化过程深入剖析重金属钝化、抗生素降解以及抗性基因赋存动态,探究了重金属对抗性基因传播的驱动机理,阐述了生物炭添加对污染物去除的强化效应。研究表明,重金属主要通过形成硫化物沉淀、吸附等方式实现形态钝化;抗生素的降解遵循非生物转化(如羟基自由基氧化)与生物降解(如共代谢、酶催化)两条途径;抗性基因以胞内/胞外DNA的动态转化形式存在,并通过垂直、水平基因转移途径迁移,同时重金属借助协同抗性、交叉抗性和协同调控的共选择机理,驱动抗性基因的传播。生物炭凭借其吸附作用、电子转移以及活性氧介导等机理,显著降低重金属的生物有效性,促进抗生素降解,并有效抑制抗性基因的传播。综合分析认为,未来研究可着重关注新型钝化材料与技术的研发、抗性基因迁移规律的解析以及循环农业模式的推广,进而实现畜禽粪污的高效处理与风险防控。

Abstract: Anaerobic digestion is a widely used technology for the resource recovery, detoxification, and volume reduction of livestock manure. Heavy metals, antibiotics, and antibiotic resistance genes (ARGs) are major pollutants commonly present in this waste. This review provides a comprehensive analysis of heavy metal passivation, antibiotic degradation, and the dynamic fate of ARGs during anaerobic digestion. It further examines the mechanisms through which heavy metals promote the dissemination of ARGs and discusses the role of biochar in enhancing pollutant removal. Current studies indicate that heavy metal passivation is primarily achieved through sulfide precipitation and adsorption. Antibiotic degradation occurs via two main pathways: abiotic transformation (e.g., hydroxyl radical–mediated oxidation) and biodegradation (e.g., co-metabolism and enzymatic catalysis). ARGs persist through the dynamic transformation of intracellular and extracellular DNA and spread via both vertical and horizontal gene transfer. Importantly, heavy metals facilitate ARGs propagation through co-selection mechanisms, including co-resistance, cross-resistance, and co-regulation. Biochar can substantially reduce the bioavailability of heavy metals, enhance antibiotic degradation, and effectively mitigate ARGs dissemination through mechanisms such as adsorption, electron transfer, and reactive oxygen species–mediated processes. Future research should focus on developing novel passivation materials and technologies, elucidating ARGs migration and transmission pathways, and promoting circular agricultural economy models. These efforts are essential for improving livestock manure treatment efficiency and minimizing environmental risks.
