摘　　要：以Fe/AC为催化剂、O2为氧化剂的非均相催化氧化体系处理偶氮染料活性红2BF,考察了反应温度、氧分压、废水pH、催化剂投加量等因素对降解效果的影响。结果表明,染料初始质量浓度为400 mg/L时,在温度150℃、氧分压0.5 MPa、pH=3、反应时间60 min、催化剂投加量为4 g/L的最佳条件下,活性红2BF色度几乎完全去除,TOC去除率达94.21%。Azo dye Reactive Red 2BF can be degraded by a heterogeneous CWAO system consisted of Fe/AC and O2. The influenced factors on degradation of dye wastewater such as temperature, oxygen partial pressure, and pH value were studied. The result showed the optimal condition as follows： the initial concentration of wastewater 400 mg/L, temperature 150 ℃, oxygen partial pressure 0.5 MPa, pH 3, reaction time 60 min, and the catalyst dosage 4 g/L. The red color of Reactive Red 2BF was almost completely removed, and the TOC removal rate was 94.21%.
