摘　　要：在100 m L连续釜式反应器中,研究了过氧化氢湿式氧化法(WPO)处理酸性红B染料模拟废水的影响因素、可生化性变化和动力学特征。结果表明,WPO法适于处理浓度较高的偶氮染料废水,废水进水p H宜保持在中性;能明显改善偶氮染料废水的BOD5/CODCr值,提高废水可生化性;通用动力学模型能较好地预测酸性红B染料废水的湿式氧化宏观过程。The influence factors, biodegradability changes and dynamic characteristics of Acid Red B simulated dye wastewater by wet peroxide oxidation（WPO） treatment was explored in a 100 m L continuous pressure reactor. The results showed that WPO was suitable for treating high concentrations of azo dye wastewater and the wastewater influent p H was appropriate to keep in neutral. WPO could obviously improve the BOD5/CODCrvalues of azo dye wastewater and wastewater biodegradability. General dynamics model could better predict the wet oxidation macro process of Acid Red B of dye wastewater.
