| Abstract: | The pretreatment of esterification wastewater from saccharin production by iron reduction neutralization coagulation precipitation process was studied in this paper.The undiluted original wastewater was pretreated under the conditions of 7 8 hours of reduction time and 120 mg/L of iron consumption at aeration.The removal rates of COD and BOD 5 could reach over 30% and 40% respectively and the colority was reduced by 50%. |
