混凝-Fenton法在制药废水生化处理后出水深度处理中的研究

摘要

采用混凝-Fenton试剂法对制药废水生化处理后的出水进行深度处理,通过正交试验研究了FeSO4·7H2O试剂、H2O2用量和反应时间等因素对COD去除率的影响,在最佳处理条件下,脱色效果较好,为制药废水生化处理后出水的深度处理提供了一种可行的方法.%Coagulation-Fenton process was chosen for the advanced treatment of pharmaceutical wastewater. Orthogonal experiment was used to study the influence of the amount of FeSO4 · 7 H2O and H2O2 and the reaction time on the COD removal rate. By analyzing the data of orthogonal experiment, the best treatment conditions is determined, ard the removal rate of chromaticity is relatively high. A feasible method for advanced treatment of pharmaceutical wastewater is provided by this study.
