The bioreactor of immobilized cells was made with a strain of bacterium named D14 with high capability of denitrifying and phosphorus accumulation used as the main bacteria and activated carbon used as the adsorption carrier. After practical wastewater with 38.5mg/L total nitrogen, 5.99mg/L total phosphorus, 315.9mg/L COD_Cr and 112.7 mg/L BOD₅ was treated for sixty minutes using the bioreactor, nitrogen removal rate was 60.80% , phosphorus removal rate was 85.97%, the removal rates of COD_Cr and BOD₅ were 69.58% and 74.59% respectively. The various indexes of discharged water were up to the National Country Wastewater Treatment Factory Wastes Emission Standard II.
