摘要
对再生水工艺中曝气生物滤池(BAF)的运行特性进行了试验研究,结果表明:BAF对浊度的平均去除率为72%,出水浊度稳定在5NTU以下;COD最佳水力负荷为7 m/h,最佳容积负荷为5.89 kg/(m3.d);NH4+-N最佳水力负荷为5.0 m/h;水力冲击负荷对硝化菌的影响较小,而对异养碳化菌影响较大。
The characteristics of BAF running in reclaimed water process were studied. The results showed that the average turbidity removal rate of BAF was 72% and the turbidity of effluent was below 5 NTU;the best hydraulic load of COD was 7 m/h and the best volume load was 5.89kg/(m^2·d); the best hydraulic load of NI-I4~ -N was 5.0 m/h; hydraulic impact load had less affection on autotrophic bacteria, but larger one on heterotrophic bacteria.
