| Abstract: | The combined process of chemical coagulation and two-stage biological aerated filter(BAF) was adopted to treat the municipal wastewater in pilot scale,particularly the removal efficiencies of organic matters,nitrogen and phosphorus at low temperature by the combined process were investigated.The wastewater was collected from Dongcheng Sewage Treatment Plant in Daqing City and the average concentrations of COD,NH3-N,TN and TP were 450 mg/L,45 mg/L,60 mg/L and 6 mg/L,respectively.Experimental results show tha... |
