| 摘 要： | 采用Fenton处理造纸废水,研究了Fenton反应中各影响因素对废水COD去除率、BOD_5/COD值的影响,确定了最佳条件,即反应时间120min,初始pH 3,H_2O_2/Fe~(2+)摩尔浓度比=3,在该条件下,废水COD去除率近85%,B/C达到0 70,可生化性得到了很大改善

| Abstract: | The papermaking wastewater was treated by Fenton's reagent.The various effects of the reagent on the removal efficiency of COD and BOD_5/COD ratio were investigated.The optimal conditions were determined.Initial pH=3,molar concentration ratio of H_2O_2/Fe~(2+)=3 and reaction time=120 min.Under the above conditions,the removal efficiency of COD was about 85%and the B/C ratio was 0.70.The biodegradability of papermaking wastewater was greatly improved. |
