ASBR中强化活性污泥与普通活性污泥降解啤酒废水的对照研究

Contrastive study between reinfored activated sludge and conventional activated sludge in the process of treating brewery wastewater in ASBR

在厌氧序批式反应器 ( ASBR)中采用优势菌群对活性污泥进行强化 ,驯化出强化活性污泥。与普通活性污泥处理啤酒废水对照显示 ,强化活性污泥较普通厌氧污泥驯化成熟时间短 ,处理效果更稳定、更有效 ,CODCr去除率最高达 95 %。培育出的强化活性污泥颗粒粒径为 1.5～ 2 .5 cm,较普通活性污泥颗粒粒径更大 。

Treatment capacity and ability of ASBR (Anaerobic Sequencing Batch Reactor) for brewery wastewater were reinforced by adding superior flora into activated sludge. Result showed that the degradation rate was up to 95%, and the diameter of reinforced activated sludge is 1.5～2.5 cm. It was found that the reinforced activated granular sludge was more uniformed and bigger than the conventional activated sludge, and the addition of superior flora can significantly shorten the inoculation of the activated sludge and improve the treatment efficiency.
