原始语种摘要: Wastewater treatment plants (WWTPs) face great challenges in developing countries, such as China, due to increasingly strict integrated wastewater discharge standard, especially for ammonium. Thus, it is very important to understand the limiting factor for ammonium removal in WWTPs. In this study, samples from 8 full-scale municipal WWTPs with different treatment processes in Pearl River Delta (PRD) area were evaluated. Bacterial and archaeal communities were investigated by high-throughput sequencing, activity of aerobic ammonium and nitrite oxidation, denitrification and anammox processes were evaluated. Nitrite, nitrate and TP concentration were strongly correlated with bacterial and archaeal composition in WWTPs based on canonical correspondence analysis (CCA). Aerobic ammonium...
