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15.31 mg/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 advantageous to the removal of COD.
