재Fenton기출상가입납미Fe3 O4,재기동초성적조건하처리록분폐수,병고찰료H2 O2,납미Fe3 O4, Fe2+,초시pH화반응시간대COD거제솔적영향。결과표명,원수pH=3,m(H2O2)∶m(COD)=0.8,n(H2O2)∶n(Fe2+)=10∶1,납미Fe3O4적투가량위0.05 g시,기동초성시간60 min후,COD적거제솔가체도94.5%。
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 .
