摘要
采用射流充氧-生物滴滤塔组合工艺技术处理生活污水,对滤塔内填料组成、回流比、负荷参数进行了优化,确定组合工艺最佳运行条件为：复合多层填料、最佳回流比为1∶2,有机负荷参数控制在0.5 m^3/m^3·d以内、最佳水力负荷为1～3 m^3/m^3·d,在此参数运行条件下,组合工艺对COD和NH4^＋-N的平均去除率可达80.1%和76.4%。
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%.
