| 摘 要： | 对使用超声波降解偶氮染料活性艳红X-3B废水进行了动力学研究。在理论分析反应过程的基础上,建立动力学方程,并根据实验进行动力学方程参数估算。结果表明:在反应开始的前20 min内,双频-Fenton,US(40 kHz)-Fenton,US[26.5 kHz(200 W)]-Fenton,US[26.5 kHz(50 W)]-Fenton,Fenton反应中污染物的降解过程均符合一级反应动力学,k1分别为0.172 9,0.149 4,0.131 1,0.101 5,0.094 1;反应30 min后降解过程符合0级反应动力学,k0分别为0.077 7,0.282 8,0.045 8,0.087 1,0.261 2。

| Abstract: | The degradation of bright-red X-3B as azo dyes in simulated wastewater by ultrasonic was studied.Based on the theoretical analysis of reaction process the dynamics engineering was established.The parameters of dynamics engineering were estimated according to the test.The result showed that in the first 20 minutes reaction,dual-frequency ultrasound-Fenton,ultrasound(40 kHz)-Fenton,ultrasound(26.5 kHz 200 W)-Fenton,ultrasound(26.5 kHz 50 W)-Fenton,Fenton all followed pseudo-first order kinetic,the values of k1 were 0.172 9,0.149 4,0.131 1,0.101 5,0.094 1 respectively;After 30 minutes,the reaction all fitted the pseudo-zero order kinetic model well,and the k0 values were 0.077 7,0.282 8,0.045 8,0.087 1 and 0.261 2 respectively. |
