摘　　要：利用Al3+ 、Fe3+ 的共聚特性和硅酸的盐效应 ,选择适当的工艺操作条件 ,对印染废水进行实验处理。实验中PSAFC作为凝聚剂 ,次氯酸钠 (NaClO)作为脱色剂 ,实验表明 :增大炭渣的用量和延长吸附时间都有利于印染废水的COD去除率的提高。By making use of copolymerization character of Al 3+ ,Fe 3+ and salt effect of silicic acid, appropriate process conditions are selected to dispose of dyeing waste water. In this experiment, after preparatory adsorption of carbon residue, PSAFC is used as flocculant, NaCLO as decolorant. The research shows that the use level augmentation of carbon residue and prolonging the adsorption will increase the leach rate of COD.
