The plastic products have large consumption over last decades, resulting in a serious microplastics (MPs) pollution. Specially, the main removal way of MPs from wastewater is to transfer MPs from liquid to solid phase, leading to its enrichment in waste activated sludge (WAS). Anaerobic digestion has been served as the most potential technique to achieve both resource recovery and sludge reduction, herein this review provides current information on occurrence, effect, and fate of MPs in anaerobic digestion of WAS. The effects of MPs on WAS anaerobic digestion are greatly related to forms, particles sizes, contents, compositions and leachates of MPs. Also, the presence of MPs not only can change the effects of other pollutants on anaerobic digestion of WAS, but also can affect the fates of them. Besides, the future perspectives focused on the fate, effect and final removal of MPs during WAS anaerobic digestion process are outlined.
在过去几十年中，塑料制品的消耗量很大，导致了严重的微塑料（MPs）污染。特别是，从废水中去除 MPs 的主要方法是将 MPs 从液相转移到固相，导致其在废活性污泥（WAS）中富集。厌氧消化已成为实现资源回收和污泥减量的最有潜力的技术，本综述提供了目前关于 MPs 在 WAS 厌氧消化中的存在、影响和归宿的信息。MPs 对 WAS 厌氧消化的影响与 MPs 的形态、颗粒大小、含量、组成和浸出物密切相关。此外，MPs 的存在不仅可以改变其他污染物对 WAS 厌氧消化的影响，还可以影响它们的归宿。此外，还概述了未来在 WAS 厌氧消化过程中关注 MPs 的归宿、影响和最终去除的研究方向。
