Abstract

Microwave has been used to enhance the removal of refractory organic contaminants from wastewater, but there are few studies about its use in landfill leachate. Mechanism and superiority of microwave irradiation are not completely clear in Fenton process. Here, removals of COD, UV254, chroma and fluorescence excitation-emission matrix spectroscopy (EEMs) in leachate by microwave enhanced Fenton process were investigated. The results indicated that microwave-enhanced Fenton process had much better degradation efficiency and was less affected by initial pH than single Fenton process due to promoting the generation rate of hydroxyl radicals and reactivity between hydroxyl radicals and organic pollutants by microwave irradiation.
