摘要
本实验用Fenton试剂对造纸废水进行深度处理研究,考察pH值、H2O2和Fe2+的用量、反应时间对废水降解过程的影响,并比较各因素的影响程度。结果表明,当pH为3.5,H2O2和Fe2+的用量分别为30mmol·L-1、4mmol·L-1,反应时间为90min时,处理效果最佳。此时,H2O2的用量为理论消耗量的1.26倍,为Fe2+用量的7.5倍。
In this experiment, Fenton reagent was used for treating papermaking effluent. The effects of the dosage of H2O2 and Fe2＋, pH, reaction time on the removal rate were investigated. In addition to this, we also compared the influence of various factors. The results showed that when the pH was 3.5, dosage of H2O2 was 30mmol·L-1, dosage of Fe2＋ was 4 mmol·L-1 and reaction time was 90 min, the treatment effect was the best. In this way, the actual dosage of H2O2 was 1.26 times of the theoretical consumption of H2O2 and 7.5 times of the dosage of Fe2＋ .
