摘　　要：焦化废水是一种典型的难降解有机废水。采用混凝-气浮法对焦化废水的处理进行了研究。探讨了絮凝剂种类,pH值,气浮时间,气浮压力等因素对废水处理效果的影响。结果表明,其废水的浊度、色度和COD的去除率可分别达到98.8%、57.1%和57.3%。Coking wastewater is a kind of typical refractory organic compound. In this paper, the experiment studies feasibility that coagulant - air flotation acts as treatment. Several elements such as the kind of flocculants, pH value, the time and pressure of air flotation process have been discussed. The experimental restdts shows that the purification efficiency of turbidity , ehroma and COD are 98.8% ,57.1% and 57.3% respectively.
