| Abstract: | The combined process of anaerobic-jet oxygenation and trickling biofilter was used to treat the domestic sewage. The composition of the filler,reflux ratio and load were optimized for the biofilter. The best performance of the combined process was determined when multilayer composite packing was used,and the optimum reflux ratio was 1 ∶2,and organic load parameters was control in the0. 5 m^3/m^3·d,and the optimum hydraulic load was 1 ～3 m^3/m^3·d. For the parameter condition,the combined process of COD and the average removal rate of NH4^＋-N can reach 80. 1% and76. 4%. |
