Keyword:  水力驱动生物转笼生物膜同步脱氮除磷;
Abstract: 为进一步成熟一种新型生物膜工艺--水力驱动生物转笼,以实际生活污水为处理对象,探讨了该工艺间歇式运行工艺参数.实验结果表明:水力驱动生物转笼具有较好的同步脱氮除磷功能,且抗冲击负荷能力强,在进水(0.2 h)→反应(5.1 h)→沉淀(0.5 h)→排水(0.2 h)的运行周期条件下,转笼转速控制0.5 r/min时,反应器容积负荷可达1.03~1.48 kg COD/(m3·d);此时,COD、SS、NH3-N、TN、TP平均去除率分别为89.7%,84.6%,73.2%,72.4%,68.4%,平均出水分别为34.9 mg/L,12.2 mg/L,9.8 mg/L,13.6 mg/L,0.56 mg/L.
