| Abstract: | An experimental study on the domestic wastewater treatment using an inner loop three phase fluidized bed reactor was presented in this paper.The formation of biofilm and effects of hydraulic retention time and volumetric gas rate on efficiency of wastewater treatment were studied.The results showed that the average COD and NH＋4-N removal rate were 83% and 95.1% under the condition of HRT 6h,volumetric gas rate 0.6m3/h and the influent COD and NH＋4-N concetration of 240.2～298.7mg/L and 29.1～68.9mg/L repectively. |
