Abstract

Abstract: Central composite design (CCD), the most popular design of response surface methodology
(RSM),was employed to investigate the effect of total organic carbon(TOC) ratio of high
molecular weight organic matter (HMW) to low molecular weight organic matter (LMW), the LMW
strength and molar ratio of hydrogen peroxide to ferrous ion on landfill leachate treatment
by Fenton process. Based on the experimental data, a response surface quadratic model in
terms of actual factors was obtained through analysis of variance (ANOVA). The model showed
that TOC removal increased with the increase of HMW to LMW ratio and the decrease of LMW
strength. There existed an optimal hydrogen peroxide to ferrous ion molar ratio for TOC
removal.

Key words: Fenton reagent, landfill leachate, oxidation
