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。The papermaking wastewater was treated by Fenton＇s reagent. The various effects of the reagent on the removal efficiency of COD and BOD5/COD ratio were investigated. The optimal conditions were determined. Initial pH=3, molar concentration ratio of H202/Fe2＋=3 and reaction time=120 rain. 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.
