摘要

    当前，厌氧污泥消化（ASD）不仅被用于处理残余污水污泥和能量回收，而且还被认为用于减少抗生素抗性基因（ARG）。 本篇综述着重说明了为什么ASD中存在抗药性细菌（ARB）和ARGs的原因，以及ASD在减少ARB和ARGs中的作用。 在ASD中已检测到ARGs和ARB，有些报告表明在ASD过程中某些ARGs可以被完全去除，而其他研究则报道了ASD之后ARB和ARGs的富集。 本文根据运行参数以及环境化学对ASD的性能进行了综述。 需要进行更多的研究来提高ASD在减少难以处理的ARG方面的性能，并在细胞外（eARG）和细胞内ARG（iARG）之间进行区分，以实现对ARG的更准确定量。

    Currently, anaerobic sludge digestion (ASD) is considered not only for treating residual sewage sludge and energy recovery but also for the reduction of antibiotic resistance genes (ARGs). The current review highlights the reasons why antibiotic resistant bacteria (ARB) and ARGs exist in ASD and how ASD performs in the reduction of ARB and ARGs. ARGs and ARB have been detected in ASD with some reports indicating some of the ARGs can be completely removed during the ASD process, while other studies reported the enrichment of ARB and ARGs after ASD. This paper reviews the performance of ASD based on operational parameters as well as environmental chemistry. More studies are needed to improve the performance of ASD in reducing ARGs that are difficult to handle and also differentiate between extracellular (eARGs) and intracellular ARGs (iARGs) to achieve more accurate quantification of the ARGs.
