文摘

Influent C/N ratio performed significant effect on NOB in CANON process. NOB was suppressed by the organic addition when C/N was lower than 1.0. NOB was enhanced by the organic addition when C/N was higher than 1.0. Nitrobacter biodiversity was always higher than Nitrospira under different C/N ratio. The influent C/N should be controlled around 1.0 for stable CANON process.
