摘　　要：利用跌水曝气浅层生物接触氧化工艺处理模拟生活污水,结果表明:温度升高、高度增加、流量增大均能使跌水充氧效果提高,其中跌水高度影响最为显著。实验确定最佳跌水高度为0.6m,反应器的合理深度为0.4m;当进水流量为40L/h,进水COD,NH3-N平均值分别为160,15.8mg/L时,两者的去除率分别为64.8%和32.7%。Simulated domestic wastewater was treated by drop-aeration biological contact oxidation process. The resuhs showed that DO was improved by raising temperature, elevating drop height and augmenting effluent flow. Of all, the height was the most important factor. The optimal drop height was 0.6 m and rational depth of the reactor was 0.4 m in the experiment. When the average of influent COD and NH3-N were 160 mg/L, 15.8 mg/L, the corresponding removal rate were 64.8% and 32.7% while influent flow rate was at 40 L/h.
