摘　　要：Fenton是酸性条件下Fe2+催化H2O2生成强氧化性的.OH,但调节pH的过程中耗费大量的酸和碱,运行费用昂贵,故Photo-Fenton反应受到重视。维生素制药废水生化后含有大量难降解污染物,以低浓度、难生物降解的实际废水为对象进行深度处理实验,研究改性粉煤灰、H2O2及FeSO4.7H2O的投加量,反应时间等因素的影响和优化。Traditional Fenton is that Fe2＋ion catalyzes H2O2 to generate strong oxidizing · OH under acid condition. But in the process of adjusting pH value, too much acid and alkali are used, making the operation cost too high. So it is necessary to value Photo-Fenton reaction. Through biological treatment, vitamin pharmaceutical wastewater contains a lot of pollutants difficult to degrage biologically. Based on this kind of low concentration, non-biodegradable industrial wastewater, an experimental study on advanced treatment was conducted. The study included the influence and optimization of the dosage and reaction time etc of the modified fly ash, H2O2 and FeSO4· 7H2O.
