HN-AD bacteria and activated sludge Rotational Speeds
a novel pure biofilm rotating biological contactor (RBC) inoculated with heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria (H-RBC) was proposed. The effects of different rotational speeds on pollutant removal efficiency and microbial community were analyzed in comparison to the RBC inoculated with activated sludge (S-RBC).
