摘　　要：邻苯二甲酸酯(Phthalic Acid Esters,PAEs)是一类常见的塑化剂,广泛应用于塑料制品的生产制造过程。PAEs会因塑料制品分解释放等多种原因和途径进入污水,逐渐迁移到污水处理厂的剩余污泥中富集。厌氧消化是污水处理厂剩余污泥的主要资源化处置方式,污泥中积累的PAEs会对剩余污泥厌氧消化过程的水解、酸化、乙酸化和产甲烷阶段以及功能微生物菌群产生不同程度的影响。然而,PAEs的种类繁多、浓度差异大且具有一定区域特性,需要详细分析不同种类PAEs对剩余污泥厌氧消化的具体影响和作用的机制。总结了剩余污泥中PAEs的种类、来源情况及检出现状,详细对比分析了不同种类PAEs对剩余污泥厌氧消化过程的影响,以期为研究人员未来在此方面的深入研究和工程技术开发提供理论依据和技术指导。Phthalic Acid Esters(PAEs)are a kind of common plasticizers,which are widely used in the manufacturing process of plastic products.PAEs will enter the sewage due to various reasons and ways such as the decomposition and release of plastic products,and gradually migrate to the excess sludge of the sewage treatment plant for enrichment.Anaerobic digestion is the main resource disposal method of excess sludge in sewage treatment plants.The accumulation of PAEs in sludge will have different effects on the hydrolysis,acidification,acetic acid and methanogenesis stages and functional microbial flora in the anaerobic digestion process of excess sludge.However,there are many kinds of PAEs with large concentration differences and certain regional characteristics.It is necessary to analyze the specific effects and mechanisms of different kinds of PAEs on the anaerobic digestion of excess sludge in detail.And summarized the types,sources and detection status of PAEs in residual sludge,and compares and analyzes the effects of different types of PAEs on the anaerobic digestion process of excess sludge in detail,in order to provide theoretical basis and technical guidance for researchers in the future in-depth research and engineering technology development.
