Abstract

Abstract

Aerobic granular sludge (AGS) technology is currently one of the promising enhanced technologies for biological wastewater treatment. However, the rapid cultivation of AGS and its long-term operational stability, especially in continuous processes, remain the main challenges faced by the application of this technology. Through literature analysis, this paper analyzes the main causes and potential mechanisms of AGS instability from the physical, chemical, and microbial aspects, and discusses the main strategies for enhancing the stability of granular sludge, namely, selective sludge discharge, particle size optimization, EPS secretion enhancement, bacterial growth rate control, excessive proliferation inhibition of filamentous bacteria, exogenous enhancement and addition of signaling molecule. In view of the complexity of the instability mechanism of AGS and the limitations of a single improvement strategy, the long-term stability of AGS structure needs to be comprehensively managed by a variety of strategies, and future research on AGS goldilocks zone should pay more attention to systematic consideration from the physical, chemical, and microbiological perspectives.
