采用臭氧氧化法降解含水溶性木素衍生物丁香酚的模拟废水，考察了初始 pH值、丁香酚初始浓度、臭氧质量浓度和温度对臭氧氧化降解丁香酚过程中 COD_Cr 去除效果的影响，并对降解过程中 COD_Cr 去除反应的动力学进行研究． 结果表明:臭氧对丁香酚具有良好的氧化降解效果，在 pH = 11、丁香酚初始浓度为 1 mmol/L、臭氧质量浓度为24． 83mg/L、温度为25℃的条件下，臭氧降解丁香酚过程中的 COD_Cr 去除率可达67． 77%;臭氧氧化降解丁香酚过程中 COD_Cr 的去除反应符合两段拟一级反应动力学特征;采用幂指数方程分析反应动力学，可分别得到 0 ～10min 和 10 ～60min 反应时间内 COD_Cr 去除反应的动力学方程．

Ozone was employed to degrade the water-soluble lignin-derived compound eugenol in a simulated wastewater system,and the effects of pH value,initial eugenol concentration,ozone mass concentration and reac- tion temperature on the COD_Cr removal as well as the corresponding kinetics were investigated.Experimental results show that (1) the ozonation process is effective in degrading eugenol; (2) the COD_Cr removal is up to 67. 77% after the ozonation with an initial eugenol concentration of 1 mmol/L and with an ozone mass concentration of 24. 83mg/L at 25℃ and pH 11; (3) the COD_Cr removal of eugenol accords well with the two-stage pseudo-first- order kinetics; and (4) the exponential function is effective in analyzing the ozonation kinetics and obtaining the kinetic models describing the COD_Cr removal within 0 ～10min and 10 ～60min，respectively.
