摘要
膜生物污染一直是膜生物反应器(Membrane bioreactor,MBR)在废水处理工艺中需要解决的一大难题。新近研究表明,基于群体感应的猝灭技术可以作为MBR活性污泥体系中一种有效的膜生物污染防治策略。因而,识别和分析群体感应产生的信号分子是应用群体猝灭技术防治MBR中膜生物污染的关键。本文首先介绍了活性污泥体系中的群体感应机理和N-酰基高丝氨酸内脂(AHLs)类化合物;接着,归纳了近期研究中针对MBR中AHLs定性和定量分析的方法;最后,对MBR中AHLs识别及分析技术的应用前景进行了展望。
Membrane biofouling has still been a major problem in membrane bioreactor(MBR) for wastewater treatment.Recently,the quorum quenching technology based on quorum sensing might been an innovative and effective strategy for controlling membrane biofouling.And thus,the recognition and analysis for the signal molecules would play a key role in the application of quorum quenching in dealing with membrane biofouling,which will provide a better understanding of the mechanism of quorum quenching technology in MBR.This paper clarified the main Nacyl homoserine lactones(AHLs) and summarized analytical methods in terms of qualitative and quantitative perspectives,respectively.The mechanism of quorum sensing and AHLs in activated sludge was introduced in details.Further,the qualitative and quantitative analysis methods of AHLs were summarized,and finally,the applications of recognition and analytical technology with respect to AHLs were proposed in MBR.
