| 摘 要： | 通过单因素影响实验和正交实验，以COD去除率和可生化性能两个指标作为筛选依据，全面研究了Fenton试剂作为预处理工艺，在常温下对实际印染废水的处理规律和最佳操作条件。首先研究了COD去除率随H2O2投加量和投加方式、FeSO4·7H2O投加量、初始pH值、反应时间等的变化规律，最后正交实验结果确定了最佳操作条件为：30％H202投加量5mL／L，FeSO4·7H2O投加量800mg／L，pH值为3．45，此时H2O2：Fe^2＋摩尔比为15．5。COD去除率为33．4％，BOD／COD值从0．139增加到0．321，可生化性能的提高为后续生物处理阶段提供了良好条件。

| Abstract: | Fenton reagent was used to treat actual dying wastewater under room temperature. First the effect of the dosage of FeSO4·7H2Oand 30% H2O2, pH and reaction time on removal efficiency of COD were investigated. And then the optimum condition was determined via orthogonal experiment： the optimum p H was 3.45, and the optimum dosage of FeSO4·7H2O and 30% H2O2 were 800 mg/L and 5mL/L, respectively. Meanwhile, the molar ratio was 15.5, and COD removal rate was 33.4% , and BOD/COD rate was 0. 321, it means the wastewater was biodegradable. |
