超声-纳米Fe_3O_4-Fenton法处理氯苯废水实验研究

Study on the Treatment of Wastewater with Chlorobenzene by Ultrasound-nano-Fe_3O_4-Fenton

在Fenton基础上加入纳米Fe3O4,在气动超声的条件下处理氯苯废水,并考察了H2O2,纳米Fe3O4,Fe2+,初始pH和反应时间对COD去除率的影响。结果表明,原水pH=3,m(H2O2)∶m(COD)=0.8,n(H2O2)∶n(Fe2+)=10∶1,纳米Fe3O4的投加量为0.05 g时,气动超声时间60 min后,COD的去除率可达到94.5%。

Based on Fenton ,wastewater containing chorobenzene is treated under air ultrasound by nano -Fe3 O4 -Fenton and also the effects of H2 O2 ,nano-Fe3 O4 ,Fe2＋ ,initial pH and reaction time on COD removal rate are investigated .The result shows when the raw water pH is 3 .0 ,m（H2O2）∶m（COD） is 0 .8 ,n（H2O2）∶n（Fe2＋ ） is 10∶1 and dosage of nano-Fe3 O4 is 0 .05 g ,the removal rate of COD can reach 94 .5% after 60 mins of gas ultrasound reaction time .
