采用升流式厌氧污泥床（UASB）-序批式反应器（SBR）组合工艺研究对小麦酒精废水的处理效果。研究结果表明：在中温（37±2）℃条件下，采用UASB反应器处理小麦酒精废水，容积负荷可达到13.0 kg/（m3·d），COD去除率稳定在85%左右，厌氧出水COD保持在1650 mg/L以下，出水挥发性脂肪酸（VFA）稳定在3.5 mmol/L以下，反应器的沼气产量维持在17 L/d左右，反应器运行稳定；采用SBR反应器处理小麦酒精废水厌氧出水，容积负荷为1.6 kg/（m3·d）， COD去除率基本保持在80%以上。经过两级生物处理，出水COD在300 mg/L以下，达到接入市政污水管网的标准。

The combined process , UASB-SBR , has been used for studying its treatment effect on wheat alcohol wastewater. The research results show that when UASB is used for treating wheat alcohol wastewater ,at the medium temperature (37 ±2) ℃,the volume loading can reach 13.0 kg/(m3·d),COD removing rate maintains steadily at about 85%,anaerobic effluent COD concentration maintains at less than 1 650 mg/L. The VFA of the effluent maintains steadily at below 3.5 mmol/L,and the biogas yield of the reactor maintains at about 17 L/d,the reactor runs steadily. When SBR is used for treating wheat alcohol wastewater ,the volume loading of the SBR reactor reaches 1.6 kg/(m3·d),COD removing rate maintains basically at 80%. After the two-stage treatment,the effluent COD is below 300 mg/L,reaching the standard for connecting with the municipal sewage pipelines.
