文摘
- •
Mainstream short-cut nitrogen removal was demonstrated in an intermittently aerated single CSTR.
- •
On-line aeration control strategy was based on in-situ ammonia, nitrite and nitrate concentrations.
- •
NOB out-selection was achieved without using external inhibitors at 25 °C.
- •
Aggressive aerobic SRT control by on-line aeration controller was crucial for NOB out-selection.
