摘　　要：研究了酸性玫瑰红废水的臭氧氧化特性和动力学规律。结果表明,臭氧对酸性玫瑰红废水的脱色具有十分理想的效果。当臭氧投加量为2.72 mg.L-1.min-1,pH为7,酸性玫瑰红质量浓度为100 mg.L-1时,酸性玫瑰红在40min内的脱色率到达97%以上,COD去除率为53.3%;在反应0～10 min,10～20 min,20～30 min时,臭氧氧化酸性玫瑰红的反应分3段符合1级反应过程,反应速率常数逐渐增大。进一步研究表明,臭氧氧化反应速率还随着染料质量浓度和pH的上升不断下降。The characteristics and kinetics of ozonation water containing acid rose dye were studied.The experimental results showed that ozone had obvious abilities in degradation of acid rose wastewater.The removal rate of absorbance and COD reached 97%and 53.3% with 2.72 mg·L-1·min-1 ozone dosage and 40 min contact time when the acid rose concentration was 100 mg·L-1.The ozonation reaction conforms to first-order reaction kinetics in the time interval of 0～10 min,10～20 min and 20～30 min.And the reaction rate constant increased continuously.In addition the reaction rate of ozonation decreased with the increase of acid rose concentration and pH value.
