Abstract: The effect of the operating parameters on the ozonation of phenol aqueous solution in the presence of activated carbon fiber （ACF） was studied. The results showed that ACF could improve the ozonation significantly；the phenol removal at 10 min was 96.8% for 1g ACF，but only 68% for 1g GAC. The efficiencies of the process under acidic conditions were almost the same and higher than those under basic conditions；the increase of basic pH led to the decrease of phenol removal at the initial stage of the ozonation. The efficiency of ACF ozonation was improved by 17% at 10min when the ozonized-air flow rate increased from 0.04m3/h to 0.16m3/h. The increase of initial concentration from 100mg/L to 500mg/L only caused the decrease of phenol removal by less than 10%，but the total phenol removal increased significantly. The repeated use of ACF showed that ozonation could provide in situ ACF regeneration，which was considered highly beneficial in the industrial treatment process.

摘要： 研究了活性碳纤维（ACF）催化臭氧化降解苯酚过程中各种参数的影响。结果表明，ACF能够显著提高臭氧化效率，当ACF为1 g，反应10 min时苯酚的去除率为96.8%，而同样条件下活性炭仅为68%；臭氧化效率在酸性下几乎相同并高于碱性下，而且在碱性下随pH值升高而降低；臭氧化空气流量从0.04 m3/h增加到0.16 m3/h，反应10 min时的效率提高为17%；苯酚初始浓度升高到500 mg/L仅使臭氧化效率下降不到10%。重复实验表明臭氧化过程中ACF的催化性能可以得到原位再生。
