Research progress in enhancing the performance of granular sludge systems by signaling molecules AHLs
Aiming at the problem of enhancing the performance of granular sludge system,the research progress of enhancing the performance of granular sludge system by signal molecules acyl homoserine lactones(AHLs)was in-troduced.The influence of exogenous AHLs on the aggregation and stability of activated sludge particles,microbial micro-ecology,and the improvement of treatment effect were analyzed.The enhancement effect of quorum sensing(QS)based on AHLs on granular sludge system was discussed.The influence of dissolved oxygen concentration,tem-perature,salinity,and pH value on the effectiveness of exogenous AHLs was summarized.The research directions and achievements in recent years were sorted out,and the future research directions are pointed out.
