摘要

       活性炭（AC）对甲烷产生的影响和抗生素抗性基因（ARGs）的归宿通过比较厌氧消化性能和ARGs在餐厨垃圾厌氧消化、餐厨垃圾和鸡共消化之间的转化来评估 粪便，以及食物垃圾和废弃活性污泥的共同消化。 结果表明，在厌氧消化器中添加 AC 通过细菌和古细菌的富集使甲烷产量至少提高了一倍。 常规消化过程显示出去除某些类型 ARG 的能力，例如 tetA、tetX、sul1、sul2、cmlA、floR 和 intl1。 在厌氧消化器中补充 AC 增强了食物垃圾单消化中大部分 ARG 的去除。 在鸡粪和废弃活性污泥等共消化物的共消化中，效果往往是最小的，两者都含有一定量的抗生素。

       The effects of activated carbon (AC) on methane production and the fate of antibiotic resistance genes (ARGs) were evaluated through comparing the anaerobic digestion performance and transformation of ARGs among anaerobic mono-digestion of food waste, co-digestion of food waste and chicken manure, and co-digestion of food waste and waste activated sludge. Results showed that adding AC in anaerobic digesters improved methane yield by at least double through the enrichment of bacteria and archaea. Conventional digestion process showed ability in removing certain types of ARGs, such as tetA, tetX, sul1, sul2, cmlA, floR, and intl1. Supplementing AC in anaerobic digester enhanced the removal of most of the ARGs in mono-digestion of food waste. The effects tended to be minimal in co-digestion of co-substrates such as chicken manure and waste activated sludge, both of which contain a certain amount of antibiotics.
