摘　　要：UASB-CASS组合工艺处理啤酒废水试验表明,最佳工艺条件为:啤酒废水在调节沉淀池内停留时间为8h;UASB容积负荷为7.2kgCODcr/(m3·d),反应时间为15h;CASS氧化池内污泥负荷为0.55kgCODcr/(m3·d)。处理后的出水水质稳定,各项指标均可达到国家《污水综合排放标准》(GB8978-96)一级排放标准。本工艺具有技术简单、抗冲击负荷能力强、节省能源、运行稳定可靠、污泥排放量少、便于操作管理等优点,适用于水质变化较大的工业废水处理。The optimal technical conditions of the application of UASB-CASS technology in the treatment of beer wastewater were as follows ：8 h stay time of beer wastewater in precipitate-regulating pits, the volume load of UASB as 7.2 kg CODcr/（m^3·d）, 15 h action time, sludge load of CASS in oxidation pits as 0.55 kg CODcr/（m^3·d）. The water after treatment had stable quality with each index in accord with National Sewage Drain Standard （GB8987-96）. The technology had the following advantages ： simple operation, strong shock resistant capability, saving energy, reliable and stable operation, low sludge drainage, convenient management etc. Such technology was especially preferred in the treatment of industrial wastewater with great changes in water quality. （Tran. by YUE Yang）
