摘要:

膜生物反应器(MBR)广泛用于处理市政污水,但膜污染仍是MBR的应用瓶颈。基于微生物群体感应(QS)理论的群体猝灭(QQ)技术是一种具有较好前景的膜污染控制方法。QQ技术可干扰微生物的QS系统,进而抑制胞外聚合物的分泌和生物膜的形成,从根本上达到控制MBR生物污染的目的。对利用QQ技术控制MBR生物污染的研究进展进行总结,提出该技术面临的挑战,并对今后采用QQ技术减缓膜污染的研究进行展望。

Abstract:

Membrane bioreactor(MBR) has been widely applied for municipal wastewater treatment, but membrane fouling is still the bottleneck problem. Quorum quenching(QQ) technology based on microbial quorum sensing is a promising method for membrane fouling control. QQ technology interferes with the QS system of microorganisms, and then inhibits the secretion of extracellular polymers and the formation of biofilm, which fundamentally control the MBR biofouling. The new progresses of QQ technology for MBR biofouling control were reviewed. The confronting challenges for this technology was proposed, and the future directions were put forward.

Key words: quorum sensing, quorum quenching, biofouling, membrane bioreactor
