In this study, two lab-scale reactors were set up and operated in this study, include a sequencing batch reactor for batch tests and a continuous predenitrification bioreactor for regular operation. Batch tests fed by Synthetic wastewater (acetate) and operated in intermittent aeration profile, demonstrate that the alternating anoxic/aerobic condition can inhibit NOB and induce nitrite accumulation from vary first time, though the sludge is collected from a complete nitrification-denitrification process. Intermittent aeration profile applied on a continuous predenitrification reactor treating low-strengthen municipal wastewater and realized partial shortcut nitrification-denitrification without changing any other operation parameters, which increased TN re-moval rate from average 60% to 70% without add extra carbon resources.
