摘　　要：采用已形成颗粒污泥的厌氧序批式反应器（ASBR）处理啤酒废水，通过正交试验考察了进水COD浓度、运行周期、进水COD浓度／碱度（以CaCO3计）值和搅拌频率这4个参数对去除COD的影响。结果表明，当以对COD的去除率为评价指标时，正交试验得到上述因素对去除COD的影响程度排序为进水COD浓度〉进水COD浓度／碱度值〉运行周期〉搅拌频率；ASBR反应器处理啤酒废水的最佳条件如下：进水COD为2859mg／L、运行周期为8h、进水COD浓度／碱度值为3～4、搅拌频率为1min／45min。ASBR反应器对COD的去除率均在95％以上，出水COD浓度能够达到《污水综合排放标准》（GB8978--1996）的一级标准和《啤酒工业污染物排放标准》（GB19821—2005）。Anaerobic sequencing batch reactor （ASBR） with granular sludge was used for treatment of brewery wastewater. The influence of influent COD concentration, operation period, influent COD/alkalinity （ calculated as CaCO3 ） value and agitation frequency on COD removal efficiency were investigated by orthogonal test. The results show that the influence order is influent COD concentration 〉 influent COD/alkalinity value 〉 operation period 〉 agitation frequency when the evaluating indicator is COD removal efficiency. The optimal parameters of ASBR for brewery wastewater treatment are recommend as： the influent COD concentration is 2 859 mg/L, the operation period is 8 h, the influent COD/ alkalinity value is 3 to 4, and the agitation frequency is 1 min/45 rain. The COD removal rate is above 95% , and the effluent COD concentration call reach the first level criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 - 1996） and the Discharge Standard of Pollutants for Beer Industry （ GB 19821 - 2005）.
