Abstract
The treatment efficiency of the secondary biochemical effluent in pharmaceutical wastewater was studied using the iron scraps enhanced Fenton process.Effects of iron scraps dosage and chemical reagent on the enhanced Fenton were investigated.The COD degradation and effluent pH value of conventional vs.enhanced Fenton were discussed.The results showed that Fe2 + was supplied in ample amounts by iron scraps in enhanced Fenton.Also,organic substances of wastewater were degraded efficiently without the addition of FeSO4 · 7H2O.Second,an initial pH of 3.8,100 g · L-1 dosage of iron scraps,0.6 mL · L-1 dosage of 30% H2O2,and reaction of 2 h with aeration achieved a COD removal rate of 66.5%,which was 20% higher than that of conventional Fenton.Furthermore,the effluent pH of conventional Fenton was about to 3.0,while the effluent pH of enhanced Fenton was above 6.0.Therefore,the iron scraps enhanced Fenton could reduce the dosage of chemical reagent and operation cost.关键词
