| Abstract: | Aerobic microelectrolysis was used to pretreat mustard wastewater.Main factors affecting the removal of COD and phosphate were discussed,including reaction time,pH and iron carbon ratio.Reaction conditions were optimized through orthogonal regression experiment,which was designed by response surface methodology.Through Design-Expert data processing software,a quadratic curved surface model was obtained.The optimum reaction time,pH and iron carbon ratio were 3.86 h,3.67,1.06 respectively,removal rate of COD ... |
