摘要: 为了考察曝气生物活性炭滤池(BACF)深度处理垃圾渗滤液的效能,研究了填料填充度、曝气位置、气水比、水力停留时间和pH等影响因素对滤池去除有机物、氨氮和总氮的影响。结果表明,最佳的工艺运行条件为:填料填充度为80%,底部曝气,气水比为3:1,水力停留时间为8h,pH为7~8。在最佳工艺条件下运行反应器,COD、氨氮和TN平均去除率分别达到85%、90%和57%,出水可达到实验设定水质要求。BACF具有较强的抗有机负荷能力,进水COD浓度在323至3000mg/L之间时,COD去除率稳定在80%。反应器受氨氮冲击负荷影响较大,氨氮进水浓度低于90 mg/L时,出水可达到要求。

Abstract: In this paper, with the aim at investigating the efficiency of advanced treatment of landfill leachate by biological aerated carbon filter (BACF), the effects of influencing factors such as filler filling degree, aeration position, air-water ratio, hydraulic retention time and pH on removal of organics, ammonia nitrogen and total nitrogen were studied. The results indicated that the optimal parameters of the combined process were as follows:filling degree of the filler was 80%, aeration position was at the bottom, gas-water ratio was 3:1, hydraulic retention time was 8 h, and pH was 7~8. Under the optimum conditions, the average removal rate of COD, ammonia nitrogen and TN was 85%, 90% and 57% respectively, and the effluent met the experimental requirement. BACF had a strong anti-organic load capacity and the removal rate of COD kept steady at 80% when COD concentration of the influent was ranged from 323 to 3000 mg/L. However, shock load of ammonia nitrogen greatly impacted the BACF. When the concentration of ammonia nitrogen of the influent was controlled below 90 mg/L, the effluent met the requirements.
