摘　　要：采用改进的一阶动力学模型研究纺织品印染废水湿式空气氧化问题,结果表明模型拟合结果与实验数据吻合,即使在高温和延长反应时间的条件下,纺织品经过印染后产生的废水中仍然存在一定比例的有机污染物,有机污染物的含量与温度无关,可以通过使用催化剂来提高比例。The improved first-order kinetic model was used to study the wet air oxidation of textile print⁃ing and dyeing wastewater.The fitting results of the model were in good agreement with the experimental da⁃ta.The results showed that even under the conditions of high temperature and prolonged reaction time,there were a certain proportion of organic pollutants in the wastewater produced by textile printing and dyeing.The proportion of organic pollutants was independent of temperature and could be improved by using catalyst.
