Microbial Community Evolution in Fe(II)EDTA-NO-based Denitrification System

An enhanced energy recovery in the form of N2O via biological Fe(II)EDTA-NO reduction is comprehensively investigated by conducting short-term and long-term experiments at different Fe(II)EDTA-NO levels. The mechanism of N2O accumulation in Fe(II)EDTA-NO denitrification system is analyzed through the microbial communities evolution.
