可用于去除高盐废水中有机污染物的混凝-Fenton氧化联合工艺
Organic pollutant removal from high-salinity wastewater by coagulation-Fenton integrated process
摘要
Abstract
The removal of organics from high salinity epoxy resin manufacturing wastewater by coagulation and Fenton processes was investigated and compared.The effects of initial pH value, Fenton's reagent or coagulant dosage and reaction time on organics removal were investigated during the oxidation and coagulation processes.Results showed that the optimum conditions for Fenton oxidation were obtained at pH =3 and the mole ratio of Fenton's reagent was n(Fe2+)/n(H2O2) =1 ∶ 20, Fe2+ dosage of 25 mmol · L-1, and H2O2 dosage of 500mmol · L-1.The maximum removal efficiency for TOC by Fenton oxidation was 62.50％ after 120 min reaction.The removal efficiency of TOC by coagulation process was 23.78％ with 300 mg· L-1dosage of FeSO4.The removal efficiencies of TOC in different Fenton and coagulation integrated processes, namely Fenton-coagulation(without addition of coagulant) process, Fenton-coagulation process, coagulation-Fenton oxidation and coagulation-two staged Fenton oxidation process, were 68.32％ ,71.51％ ,80.69％ and 89.27％ , respectively.关键词
