摘要采用化学活化法将造纸污泥制备成活性炭，运用SEM、BET、EDS、FT-IR等常规表征技术分析其理化性质，再将制备的污泥活性炭作为催化剂，应用于催化臭氧氧化降解橙黄Ⅱ模拟染料废水，并考察不同因素对橙黄Ⅱ降解效果的影响，探究污泥活性炭催化臭氧氧化橙黄Ⅱ的反应机理.结果表明：（1）造纸污泥活性炭的理想制备条件为：原污泥与氯化锌质量比为1：2，活化时间为12 h，炭化温度为600℃，炭化时间为60 min.（2）在污泥活性炭催化臭氧体系中，污泥活性炭投加量和臭氧流量的增加有利于橙黄Ⅱ去除率的提高，但随着溶液初始pH值的增大，橙黄Ⅱ去除率降低.

Abstract：The activated sludge activated carbon (SAC) prepared by chemical activation method was characterized by several methods including SEM, BET, EDS, FT-IR. The prepared SAC performed as catalyst in ozonation degradation of orange Ⅱ, and the removal efficiency of orange Ⅱ under different reaction conditions was investigated. In addition, the reaction mechanism of degrading orange Ⅱ through catalytic ozonation with SAC was studied. The results indicated that the optimal preparation conditions are as follows:the mass ratio between sludge and activation reagent is 1:2, activation time is 12 h, buring temperature is 600℃, burning time is 60 min. Moreover, the increase of SAC dosage and ozone inlet fluxes was beneficial to the removal efficiency of orange Ⅱ. However, orange Ⅱ removal rate decreased when the initial pH value of the solution increased.

Key words： dye wastewater catalytic ozonation paper mill sludge activated carbon orange
