| 摘 要： | 三烯丙基异氰脲酸酯（TAIC）生产废水具有有机物浓度高、难降解的特点，常规的处理方法对其处理效果普遍较差。本研究采用O3/ACF协同催化氧化技术，以三烯丙基异氰脲酸酯（TAIC）生产废水为研究对象，分析了O3/ACF催化降解TAIC废水的作用机理，并考察了ACF（活性炭纤维）用量、O3浓度、pH、TAIC初始浓度及ACF使用次数对处理效果的影响。实验结果表明：通过投加叔丁醇和双氧水的对比分析，验证了反应过程中·OH自由基的存在；在ACF投加量为1.2 g·L-1，TAIC初始浓度200 mg·L-1，pH 7.0，臭氧浓度2 g·h-1，反应40 min后，TAIC的去除率为93.54%。

| Abstract: | Triallyl-isocyanurate (TAIC) production wastewater features highly concentrated organic matter that is difficult to degrade, especially when treated by traditional methods. This study analyzed the mechanism of degrading TAIC in wastewater by O3/ACF synergistic catalysis and investigated the impact of several influential factors, such as ACF dosage, ozone concentration, pH, initial concentration of TAIC, and ACF usage. The results verified the presence of·OH in the process by a comparative analysis that uses tert-butanol and H2O2. The highest removal rate of TAIC was 93.54%, which occurred under the following conditions:ACF dosage of 1.2 g·L-1, initial TAIC concentration of 200 mg·L-1, pH of 7.0, ozone concentration of 2 g·h-1, and reaction time of 40 minutes. |
