Denitrifying Phosphorus Removal in Two-sludge Baffled Reactor
The start-up of denitrifying phosphorus removal in two-sludge baffled reactor to treat domestic sewage was studied.When influent organic load was 0.5 kg/(m·3d),C/N was 5,the temperature was 30(±0.5)℃,HRT was 11.08,R was 0.4,r was 0.38 and SRT was 20 d,the removal efficiency of CODCr,TN,TP and NH4+-N was 67%,63 %,50% and 82 % respectively,and effluent concentration was 70 mg/L,18 mg/L,2.8 mg/L and 6.8 mg/L respectively.It shows that the study on denitrifying phosphorus removal in this system is feasible.
