Research progress of filamentous sludge bulking control by quorum sensing and quorum quenching
During the process of sewage purification by activated sludge method,overgrowth of filamentous bacteria always causes sludge bulking.Utilizing microbial quorum sensing mechanism is an emerging strategy for filamentous sludge bulking control.The control strategies for filamentous bacteria bulking and the mechanisms of microbial quorum sensing were introduced;the research progress of filamentous bacteria bulking control by quorum sensing and quorum quenching was elaborated with its influencing factors analyzed at the same time.The future research direction of the said technology was pointed out,which provided a new theoretical approach for filamentous sludge bulking control.
