Yellow River Basin Pollution Control: Sodium Acetate Carbon Source in Northern WWTPs

Under the national strategy of ecological protection and high-quality development in the Yellow River Basin, WWTPs along the basin face tighter TN and TP discharge standards.

Low winter temperatures in the north slow nitrification and denitrification, increasing external carbon source demand. Sodium acetate, with fast denitrification rate and usability at low temperature, is widely used in municipal and industrial park WWTPs in the Yellow River Basin, helping improve basin water quality.
