Study on Wastewater Treatment by Biological Aerated Filter

Abstract:

In order to study the pollutants removal effect, the reactor operating conditions were studied with Biological Aerated Filter　(BAF)　process. The results showed that when HRT was at 8h, the effluent COD and ammonia nitrogen were 37 mg/L and 8.6 mg/L with the aeration flow was 0.3 m3/h, the effluent COD and ammonia nitrogen were 53 mg/L and 12.2 mg/L respectively. And the range of effluent pH is at 6.0-8.8. Furthermore the effluent COD was stable, while the effluent ammonia nitrogen will gradually affect by aeration flow. So the BAF process for residential sewage treatment is feasible.
