增加内循环的生物反应器对啤酒废水处理效率的研究

Improvement of brewery wastewater treatment by adding internal cycle in airlift bioreactor

用生物流化床反应器和气提式接触氧化生物反应器处理啤酒废水时 ,分别从废水COD的降解速率和去除率考察了有、无内循环时 ,对啤酒废水降解效率的影响 .结果表明 ,增加内循环装置 ,可以强化气 -液传质 ,明显地提高啤酒废水处理的效率 .

When brewery wastewater was treated in fluidized bed bioreactor and biofilm airlift bioreactor, both of the bioreactor equipped with or without internal cycling tube were invesigated respectively on the COD removal rate and COD reduction speed. The experimental results indicated that the wastewater treatment was effectively improved by adding internal cycle both in fluidized bed bioreactor and biofilm airlift bioreactor.
