| 摘 要： | 采用Fenton法预处理难降解干法腈纶废水,选取H2O2用量、Fe2+用量、初始pH和反应温度4个因素为变量,COD去除率为响应值进行中心组合设计。利用响应面法对实验结果进行分析,建立了以COD去除率为响应值的二次多项式模型并进行了显著性检验,分析了各因素单独及交互作用对COD去除率的影响,确定了最佳反应条件,并考察了最佳条件下处理前后废水可生化性和毒性变化。结果表明,所选取的4个因素影响COD去除率的主次顺序依次为:H2O2用量、Fe2+用量、初始pH和反应温度;在H2O2浓度为90.0 mmol/L、Fe2+浓度为23.9 mmol/L、初始pH值为3.4、温度为38.5℃的最佳条件下,COD去除率为53.8%,与模型预测值51.9%吻合度较高,偏差仅为3.66%;最佳条件下处理后废水可生化性显著提高,生物毒性明显降低,适宜于后续的生化处理。 |
