채용Fenton시제대갑철폐수진행양화처리,고찰료H2O2농도、Fe2+농도、pH치、반응시간등인소대처리효과적영향。재H202투가량위4.5ml/L,n(H202):n(Fe2+)=4,pH치위3,반응30rain후,정치5min적조건하,폐수중갑철거제솔화COD거제솔분별체도89%、82%。결과표명,Fenton시제대갑철폐수가이취도흔호적처리효과。
Fenton reagent is used for treating H202 and Fe2 ~ , pH value, reaction time and the dosages of H202 is around 4.5 ml/L,n( min and ended the reaction after stewing 5 wastewater are respectively 89% ,82%. The aldehyde wastewater. formaldehyde wastewater, the effects of the concentration of other factors on the treatment effect are investigated. When n2 02 ) : n ( Fe2 + ) = 4, pH value is 3, the stirring time is 30 rain, formaldehyde removal rate and COD removal rate in result showe that fenton reagent had good effect for the form-aldehyde wastewater.
