DGGE Analysis Bacterial Community Structure of Advanced Sludge Reduction Process

Abstract

Bacterial community structure of advanced HA-A/A-MCO sludge reduction process is analyzed by DGGE fingerprinting technology. Research results indicates that microbial flora showed the distinction of highly diversity in anaerobic tank, anoxic tank and MCO tank of the HA-A/A-MCO process, and each tank has its own diversified and stable dominant microorganisms, as so the co-activation of such preponderant bacterial community promotes the system to exert favourable and consistent function of phosphorous and nitrogen removal and sludge reduction.
