摘要
以生化+气浮处理后的烟草薄片废水为研究对象,对废水进行芬顿实验,考察了反应时间、pH、硫酸亚铁及双氧水投加量对COD去除率的影响。研究表明,在双氧水投加量为0.91ml/L,硫酸亚铁投加量为0.5g/L,反应时间1.5h时,芬顿的处理效果较经济。此时COD去除率为73.3%,出水COD为80mg/L。
In this paper,the effect of reaction time,pH,ferrous sulfate,and hydrogen peroxide dosage on the removal rate of COD by Fenton test were studied. The results showed that the effect of Fenton was comparative economy when the dosage of hydrogen peroxide was 0. 91 m L/L,the dosage of ferrous sulfate was 0. 5 g/L,and the reaction time was 1. 5 h. The removal rate of COD was 73. 3%,and the effluent COD was 80 mg/L.
