Vertical-flow constructed wetland based on pyrite intensification: Mixotrophic denitrification performance and mechanism

•Mixotrophic denitrification (C/N = 3) was achieved in the pyrite-based VFCW.•The highest TN and TP removal rate were achieved with the pyrite addition (100%).•The mixed addition of pyrite was better for N and P removal.•The autotrophic and heterotrophic bacteria were significantly promoted by pyrit...
