摘要: 摘要:试验采用超声波作用去除垃圾渗滤液中COD和氨氮。通过正交设计,探讨了活性炭用量、pH值、超声波功率、辐照时间、曝气时间5个因素对COD和氨氮去除率的影响。结果表明在活性炭用量1.0g,pH为9,超声波强度为360W,辐照时间为6min,曝气时间为6min时处理COD和氨氮综合去除效果最好,COD去除率为63.7%,氨氮去除率为80.24%。

Abstract: The experiment used ultrasound to remove COD and NH3-N in landfill leachate. By orthogonal design,the effect activated Carbon, pH,ultrasonic power,irradiation time and aeration time exert on the removal rate of COD and NH3-N is worked out. The results show that:effect of the pretreatment experiment is best when activated Carbon is 1.0g,pH is 9,ultrasonic power is 360w,irradiation time is 6min and aeration time is 6min,of which the removal rate of COD is 63.7% and of NH3-N is 80.24%.
