Abstract: 采用50m3螺旋式厌氧反应器(SPAC反应器:反应器主体直径2.4m,高11m)试验了高浓度安乃近制药废水厌氧生物处理的性能.中试结果表明,在进水COD为10000~14000mg·L-1和水力停留时间(HRT)为12h的工况下,容积COD去除速率(VRR)达到(26.54±4.61)kg·m-3·d-1,容积产气速率(VPR)达到(9.55±1.66)m3·m-3·d-1,COD去除率达到94.8%.根据Monod方程拟合结果和负荷冲击试验结果推测,SPAC反应器的最大容积效能可分别达46.08和75.00kg·m-3·d-1.螺旋式厌氧反应器具有很强的抗冲击能力,在基质浓度跃升到原浓度的3倍及进水流量跃升到原流量的1.5倍时,容积效能没有明显波动,COD去除率保持在95%以上;SPAC反应器处理高浓度制药废水的适宜操作条件为进水COD30000mg·L-1,HRT长于12h.
