摘　　要：采用聚糖菌活性污泥系统处理酿酒工业废水，考察了不同pH和厌氧／好氧时间比对COD、TP、TN处理效果的影响。结果表明：当pH在6.0～7.1时，pH越低，越有利于提高聚糖菌对乙酸盐的吸收速率，出水COD最低仅为15．31mg／L，COD去除率最高可达97％。当厌氧／好氧时间比在1-2时，系统COD去除率能维持在95％以上，但该比值越大越不利于氮和磷的去除。当厌氧／好氧时间比小于1时，不利于COD的去除。Glycogen-accumulating organisms activated sludge systems have been used for treating brewing waste- water. The influences of different pH and anaerobic/aerobic time ratio on the treatment effects of COD ,TP, and TN are investigated. The results show that when pH is 6.0-7.1, the lower pH is, the more advantageous to the increase of acetate absorption rate by using glycogen accumulating organisms, and the minimum concentration of effluent COD is only 15.31 mg/L, the maximum COD removing rate can be as high as 97%. When anaerobic/aerobic time ratio is within the range of 1-2, system COD removing rate can be maintained at more than 95%. But the higher the ratio is, the less advantageous to the removal of N and P. When anaerobic/aerobic time ratio is less than 1,it is not advantazeous to the removal of COD.
