| 摘 要： | 设计了两段厌氧处理系统来处理糖果废水，该系统由升流式厌氧污泥床（UASB）和降流式厌氧生物滤池（DFAF）组成. UASB和DFAF反应器分别在35℃和室温(22～25℃)下运行，系统水力停留时间是2.4d. 在有机负荷12.5kgCOD/m3·d时系统COD去除率为98％，并且在高有机负荷情况下UASB仍能获得较好的处理效果. 通过回流可以调节UASB反应器进水COD质量浓度保持在30g/L以下. 系统DFAF反应器出水COD质量浓度维持在400mg/L以下，并能有效缓冲UASB反应器出水的波动.

| Abstract: | A two-step anaerobic reactor treatment system was tested for its ability to remove organic carbon from confectionery industry wastewater. The system consists of an up-flow anaerobic sludge blanket （UASB） operated at 35℃, which is followed by a down-flow anaerobic filter （DFAF） operated at ambient temperature (22～25℃). The system has a total hydraulic retention time of 2.4 days. An overall COD treatment efficiency of 98% was observed at the system organic loading rate of 12.5kgCOD/m3·d, which worked extremely well at high organic loadings. Effluent recycle enables the UASB to operate with influent COD concentrations up to 30g/L. DFAF maintains effluent COD concentrations below 400mg/L, and effectively buffers fluctuations in the effluent of the UASB. |
