Study on Characteristic of Nitrification in Three-phase Inter-circulating Biological Fluidized Reactor
Three-phase inter-circulating biological fluidized reactor was designed and its characteristic of nitrification was studied.The results showed that the removal efficiency of NH4+-N was optimal,above 80 %,when HRT was 4 h,DO was 3 mg/L,temperature was 25 ～ 30 ℃ and CODCr load per unit was 4 kg/(m3·d).
