Popis:	The combination sequence of traditional hybrid constructed wetlands (HCWs) affects the removal of nitrogen in raw sewage, but the effect of the combination sequence on nitrogen removal pathway have seldom been reported, especially the specific conditions allowing anammox to occur. Three-stage HCWs, namely vertical flow (VF), horizontal flow (HF) and surface flow (SF) constructed wetlands, were arranged in six different sequences to investigate nitrogen removal efficiencies and microbial removal pathways using metagenomic and stable isotope analyses. Results showed that the combination sequence significantly affected nitrogen removal pathways in HCWs. We found the best removal of total nitrogen (~50%) and ammonium (NH
