摘要:

膜曝气生物膜反应器(MABR)有效地将生物膜法技术和膜分离技术结合在一起,在污水脱氮方面潜力巨大。以MABR处理模拟生活污水和豆制品加工废水,着重考察了MABR的稳定性及脱氮性能。结果表明,在HRT=12 h、曝气压力=10 kPa和C/N=5时,MABR对模拟生活污水处理效果最佳,COD、氨氮、TN的平均去除率分别为92.0%、86.5%、83.3%。而在HRT=8 h和曝气压力=10 kPa时,MABR对豆制品加工废水处理效果最佳,COD、氨氮、TN的容积负荷分别为1 320、125.5、184 g/(m3·d),平均去除率分别可达到84.2%、81.5%、79.7%,优于传统生物膜法脱氮。

Abstract:

Membrane aerated biofilm reactor (MABR) effectively combines biofilm technology and membrane separation technology,which has great potential in wastewater denitrification. This paper focuses on the stability and nitrogen removal performance of MABR,which is used to treat soybean processing wastewater and simulated domestic wastewater. The results showed that when HRT was 12 h,aeration pressure was 10 kPa and C/N ratio was 5,MABR had the best treatment effect on simulated domestic sewage,and the average removal rates of COD,ammonia nitrogen and TN were 92.0%,86.5% and 83.3% respectively. When HRT was 8 h and aeration pressure was 10 kPa,MABR had the best treatment effect on soybean processing wastewater. The volume loads of COD,ammonia nitrogen, TN were 1 320,125.5,184 g/(m3·d) respectively,and the average removal rate had reached 84.2%,81.5%, 79.7% respectively,which was superior to the traditional biofilm method for nitrogen removal.

Key words: membrane aerated biofilm reactor, denitrification, C/N ratio, aeration pressure, soybean processing wastewater
