%X A new tubular reactor based on jet aeration was constructed.Influences of organic loading and DO on treatment efficiency of reactor were investigated.The experimental results showed that when temperature was 15℃,DO was 6.0 mg/L,organic load rate was 1.0 kg COD/(m3·d),nitrogen load rate was 0.30 kg TN/(m3·d) and HRT was 8 h,the tubular reactor exhibited good removal efficiency.The influent COD,NH+4-N,TN were 335 mg/L,105 mg/L and 110 mg/L,respectively while the effluent was 43 mg/L,14 mg/L and 18 mg/L,respectively,with the removal rates of 87%,86% and 83%,respectively.DO had notable influence on the nitrogen removal of tubular reactor.When DO was 6 mg/L,a system of simultaneous nitrification and denitrification could be constructed with the NH+4-N and TN removal rate of 96.6% and 86.7%,respectively.
