| Abstract: | Through experiments on fracturing wastewater treatment of low permeability oilfields,this paper studies the technology of viscosity reduction pretreatment-Fe/C microelectrolysis-flocculation which effectively reduces COD in wastewater.Furthermore it focuses on the influencing factors such as H2O2,pH,Fe/C weight ratio,Fe/C dosage,Ca(OH)2 dosage and reaction time.The results show that the optimal conditions for this experiment are : the dosage of H2O2 is 0.5%,pH 1.0,the Fe/C weight ratio is 1∶1,the dosage of Fe/C 4-5g/L,the dosage of Ca(OH)23g/L and reaction time 120min. |
