Effects of COD/TN ratio on nitrogen removal efficiency, microbial community for high saline wastewater treatment based on heterotrophic nitrification-aerobic denitrification process

[Display omitted] •The optimal treatment performance was achieved in high saline HN-AD system with COD/TN ratio of 25.•The dominant nitrogen removal functional bacteria and pathways shifted under different COD/TN ratio.•HN-AD bacteria Pseudomonas, Bacillus and Paracoccus played a key role in the sys...
