摘要：采用50 m³螺旋式厌氧反应器(SPAC反应器:反应器主体直径2.4 m,高11 m)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10000~14000 mg·L^-1和水力停留时间(HRT)为12 h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75.00 kg·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COD 30000 mg·L^-1,HRT长于12 h.

Abstract：The performance of pilot-scale spiral automatic circulation (SPAC) anaerobic reactor with a capacity of 50 m³ in treating high concentration analgin pharmaceutical wastewater was investigated. The results showed that the SPAC reactor had high volumetric COD removal rate (VRR) of (26.54±4.61) kg·m^-3·d^-1, volumetric gas production rate (VPR) of (9.55±1.66) m³·m^-3·d^-1 and COD removal efficiency of 94.8% at (30±5) ℃ when the influent COD concentration was about 10000~14000 mg·L^-1 and the hydraulic retention time (HRT) was 12 h. According to the results from Monod equation fitting and load shock test, the highest volumetric efficiency of SPAC reactor were extrapolated to be 46.08 and 75.00 kg·m^-3·d^-1, respectively. The SPAC reactor displayed good performances in shock loading tests by increasing influent COD concentration or inflow rate. When the influent COD concentration increased by 200% or the inflow rate increased by 50%, the COD removal rates remained stable, and the COD removal efficiency stayed above 95%. The SPAC reactor was suitable for the treatment of analgin pharmaceutical wastewater with COD concentration of 30000 mg·L^-1 and HRT longer than 12 h.
