Brewery wastewater was treated in a pilot-scale anaerobic sequencing batch reactor (ASBR) in which a floating cover(@) was employed. Long time experiments showed that the reactor worked stably and effectively for COD removal and gas production. When the organic loading rate was controlled between 1.5 kg COD/m3 d and 5.0 kg COD/m(3)d, and hydraulic retention time one day, COD removal efficiency could reach more than 90%. Sludge granulation was achieved in the reactor in approximately 60 days, which is much less than the granulation time ever reported. In addition, high specific methanogenic activity (SMA) for formate was observed. The study suggests that the ASBR technology is a potential alternative for brewery wastewater treatment.
采用中试规模的厌氧序批式反应器（ASBR）处理啤酒厂废水，该反应器采用浮动盖（@）。长期实验表明，该反应器在去除化学需氧量（COD）和产气方面运行稳定且有效。当有机负荷率控制在1.5 kg COD/m³·d至5.0 kg COD/m³·d之间，水力停留时间为一天时，COD去除效率可达90%以上。该反应器在大约60天内实现了污泥颗粒化，这比以往报道的颗粒化时间短得多。此外，还观察到对甲酸盐具有较高的比产甲烷活性（SMA）。该研究表明，ASBR技术是处理啤酒厂废水的一种潜在替代方法。
