新型双阳极电助芬顿体系降解抗生素机理研究
Mechanism study on antibiotic degradation by novel dual-anodes electro-assisted Fenton system
摘要
Abstract
A novel dual-anode electro-assisted Fenton system consisting of iron sheet,platinum sheet and carbon felt cathode was constructed.Among them,the iron sheet-carbon felt was operated at lower voltage,and the dissolved Fe2+and the added H2O2 occurred homogeneous Fenton reaction to generate·OH for rapid degradation of sulfamethoxazole(SMX),while the generated Fe3+migrated to the surface of the carbon felt to be reduced to Fe2+to participate in the reaction.In the system,the Pt-carbon felt was operated at higher voltage to maintain the efficient recycling of Fe2+→Fe3+→Fe2+,while the iron sheet adopted the intermittent operation mode to prevent the excessive dissolution of Fe2+and realize the reduction of the amount of iron sludge.The dual-anode electro-assisted Fenton system could successfully treat antibiotic wastewater from actual pharmaceutical industry under low iron accumulation,with a chemical oxygen demand(COD)removal rate of 68.3%and a significant increase in wastewater biochemistry.关键词
