•Zinc ion performed significant inhibition on Anammox process.•AAOB had self-adaption to elevated Zn (II) in 1–10 mg L−1.•The irreversible suppression threshold on AAOB was 20 mg L−1 Zn (II).•Zn (II) addition led to the biodiversity increase of Anammox system.•Relative abundance of AAOB significantl...
