Anaerobic baffled reactor (ABR) technology has emerged as a promising approach for decentralized wastewater treatment due to its simplicity and effectiveness. This book chapter comprehensively reviews recent advancements in ABR technology, emphasizing its application in decentralized wastewater management. It covers the fundamental principles and design features of ABRs, demonstrating their suitability for such settings. The chapter discusses recent developments in reactor design, operational parameters, material selection, and the optimization of ABR performance, particularly in terms of COD (chemical oxygen demand), Biological Oxygen Demand (BOD), and Total Suspended Solids(TSS) removal efficiency with varying hydraulic retention times (HRTs). Additionally, it explores the integration of ABRs with other wastewater treatment technologies, such as pretreatment and posttreatment processes, to enhance overall treatment efficacy. Studies highlighted in the chapter show that ABRs can achieve up to 98% COD removal, with longer HRTs generally resulting in improved treatment outcomes, especially for domestic wastewater.

摘要

Anaerobic baffled reactor (ABR) technology has emerged as a promising approach for decentralized wastewater treatment due to its simplicity and effectiveness. This book chapter comprehensively reviews recent advancements in ABR technology, emphasizing its application in decentralized wastewater management. It covers the fundamental principles and design features of ABRs, demonstrating their suitability for such settings. The chapter discusses recent developments in reactor design, operational parameters, material selection, and the optimization of ABR performance, particularly in terms of COD (chemical oxygen demand), Biological Oxygen Demand (BOD), and Total Suspended Solids(TSS) removal efficiency with varying hydraulic retention times (HRTs). Additionally, it explores the integration of ABRs with other wastewater treatment technologies, such as pretreatment and posttreatment processes, to enhance overall treatment efficacy. Studies highlighted in the chapter show that ABRs can achieve up to 98% COD removal, with longer HRTs generally resulting in improved treatment outcomes, especially for domestic wastewater.
