  • Abstract
    Through comparing the effluent quality under three conditions with different dissolved oxygen concentration in A2/O bioreactor, results showed that the aeration and TN removal rate under condition 3 compared with the condition 1 reduced 52.6% and enhanced roughly 12% respectively. Under the condition 3, the low oxygen condition reduced the sludge nitration performance, but it still could have NH4+-N nitrified, make NH4+-N in effluent below 2 (mg·L-1).
