Abstract

The effects of individual membrane processing ( MP) and MP combined with coagulationflocculation ( CF) on the properties of secondary fiber wastewater had been investigated in this study． Based on taguchi method and analysis of variance ( ANOVA) ，four independent variables including PAC dosage，CPAM dosage，pH and temperature were selected as influence factors． The factors were optimized as PAC dosage 1000mg/L，CPAM dosage 20mg/L，pH 9 and temperature 25 ℃． At the optimal conditions，COD was declined to 441 mg/L，TSS was 4NTU，SV was 46，colority was 23 Units PtCo． Compared with individual MP， the combination of CF and MP has a higher flux at 70% and a stronger removal of COD at 60. 2% after 10 mins’MP， indicating that the combination of CF-MP improves the overall performance for the secondary fiber wastewater treatment．
