摘　　要：采用三角形波电源、正弦波电源、全波整流电源进行动态实验,研究采用不同电源波形和波形频率电源的电凝聚对处理生活污水的影响,以及对有机污染物的去除特性.结果表明,三角形波电源的波形频率为50次.s-1时和正弦波电源波形频率为16.5次.s-1时的处理效果较好.采用上述三种电源波形的电凝聚主要去除的是悬浮态有机污染物.Dynamic experiments of domestic sewage treated by electrocoagulation process with triangle-wave power, sine wave power and full-wave rectifier power, which had the different power waveform and waveform frequency, were studied. And the removal characteristics of organic pollutants were studied. The results showed that treatment effects were better when the waveform frequency of triangle-wave power was 50 times per second and when the waveform frequency of sine wave power was 16. 5 times per second. The suspended organic pollutants were mainly removed by electrocoagulations with the above power waveform.
