摘　　要：以阳离子红X-GRL溶液模拟染料废水,以阴离子表面活性剂十二烷基苯磺酸钠(SDBS)为捕获剂,对气浮法处理染料废水的工艺进行了研究。研究了pH、气体流量、表面活性剂用量、装液量对染料废水脱色率的影响。用正交实验法确定了最佳工艺条件:pH为9.0、气体流量为300 mL/min、装液量为450 mL、表面活性剂浓度为1.4 mmol/L,此条件下,阳离子红X-GRL脱色率为95.7%,富集比为13.5。The technology of dealing with dying wastewater by air flotation was studied by using cation red X - GRL as simulative wastewater. The pH value, influence of gas flow rate, concentration of surfactant, volume of the solution on removal rate was investigated by using sodium dodecyl benzene sulfonate （SDBS） as anion surfactant. The orthogonal results showed that under the conditions of pH 9.0, gas flow rate 300mL/min, volume of the solution 450 mL, concentration of SDBS 1.4 mmol/L, the removal rate and enrichment ratio of cation red X-GRL are 95.7% and 13.5, respectively.
