A lab-scale SBR was employed to treat domestic wastewater and investigate the achievements and stability of shortcut biological nitrogen removal under real-time control conditions.The results show that stable shortcut nitrification and denitrification can be achieved in 67 days under real-time control conditions.The nitrite accumulation rate(NO~-_2-N/NO~-_x-N) is over 80%.Then,the reactor is operated under fixed-time control and the nitrite accumulation rate decreases gradually.It is… CONTINUE READING
