Recently,the quorum quenching technology that is based on the quorum sensing in the MBR, which has been an innovative and effective strategy for controlling biofouling in the previously studies. And thus, the recognition and analysis for the signal molecules of quorum sensing have limited the application of quorum quenching in the MBR with respect to membrane biofouling. This paper intends to clarify N-acyl homoserine lactone (AHL) and summarize the analytical methods, such as qualitative and quantitative analysis, in order to understand this technology more better. Firstly, this paper introduced the mechanism of quorum sensing and AHL in activated sludge. Further, the analysis of AHL, including qualitative and quantitative methods were summarized, and finally, future application of AHL’s recognition and analytical technology in MBR were proposed. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
