摘要
以苯酚模拟废水作为研究对象,采用超声电化学耦合技术对含酚废水进行处理,考察超声波频率、电流、pH值及粉煤灰负载TiO_2-Fe^(3+)粒子加入量等因素对含酚废水中苯酚去除效果的影响,实验结果表明,在超声波频率为45 kHz、电流为1.2 A、pH=5、粉煤灰负载TiO_2-Fe^(3+)粒子加入量为3g的条件下,含酚废水中苯酚的去除率达到最佳.
In this work,taking wastewater as the research object,we used the treatment of phenol containing wastewaterby ultrasonic electrochemical coupling.The influence factors in the process of experiments including ultrasonicfrequency,current,pH value and fly ash load Fe3+-TiO2particle amount conditions were explored.The resultsshowed that the best phenol removal was obtained when the frequency of45kHz,current of1.2A,initial pH of5,addition of3g under the conditions of fly ash load Fe3+-TiO2,the phenol got the better treatment effect.
