摘　　要：采用超声/微电解联合体系处理丙烯腈聚合废水,考察了反应时间、铁水质量比、初始pH值、超声功率对废水COD降解效果的影响。结果表明,在初始p H值为4,反应时间为30 min,铁水质量比为1∶10,超声功率为200 W的最佳试验条件下,COD去除率达到51.5%。反应动力学研究表明,超声对微电解技术有良好的的协同作用,协同因子E=2.33。Using ultrasonic/microelectrolysis combined system to treat acrylonitrile polymeric wastewater,the effects of reaction time,mass ratio of iron to water,initial pH value of the wastewater,and ultrasonic power on COD degradation were investigated.The results indicated that,under the optimal process condition:the pH value was 4,the reaction time was 30 min,the mass ratio of iron to water was 1∶10,the ultrasonic power was 200 W,the removal rate of COD reached 51.5%.The reaction kinetics study indicated that,ultrasound had a good synergistic effect on microelectrolysis technology with the synergistic factor E=2.33.
