摘　　要：针对印染废水经过射流曝气活性污泥法处理后的絮体十分轻飘,沉降困难,沉淀效果难以令人满意的特点,将加压溶气气浮技术应用于印染废水的处理。通过工程现场实际运行发现:应用加压溶气气浮技术处理印染废水悬浮物的去除效果好。The floc after the jet aeration activated sludge treatment in the printing and dyeing wastewater is very buoyant and difficult to settlement,and the dissolved air flotation is considered in the treatment of printing and dyeing wastewater.Through the operation in the project site,the good result of the removal of suspended solids has been obtained in the dissolved air flotation treatment.
