Here, we compared sodium acetate and glucose in an SAD system at a salinity of 25 g/L. The sodium acetate-enhanced system achieved superior removal rates of 90.55 % for NO₃⁻-N and 85.13 % for total nitrogen (TN), compared with 82.62 % (NO₃⁻-N) and 81.11 % (TN) with glucose. Sodium acetate also resulted in significantly lower nitrite (NO₂⁻-N) accumulation. Furthermore, it promoted higher heterotrophic denitrification contribution and chemical oxygen demand (COD) utilization rates than those observed with glucose.

By integrating DBO for targeted hyperparameter tuning within the XGBoost framework, the model effectively captures nonlinear dependencies, achieving superior predictive accuracy (R² = 0.95, RMSE = 0.11).
