Leachate Treatment by Heterogeneous Fenton on an Activated Carbon Substrate with Fe(II) Impregnated

Abstract

Organic components contained in leachates resulting from decomposition of waste are difficult to degrade. They also contain inorganic components, as nitrogen compounds, phosphates, and chlorides, also Ca, Mg, K, and heavy metals. Leachate volume and its composition vary depending on biogeochemistry of type site of deposited residues, and age of sanitary landfill. In this study, it conducted a Heterogeneous Fenton, advanced oxidation process using lignitic activated carbon as solid matrix, with and without Fe 2+ impregna-

Treatment Processes of Leachate from a Landfill by Advanced Oxidation Fenton and Ozone-UV

“…The oxidation by the Fenton reagent has been shown to be effective in the treatment of leachates [6] [8] [9] [10] and [11], in which the pollutant load is treated with a combination of Fe 2+ and H 2 O 2 . This oxidation consists of a homogeneous catalytic system in which an iron salt, which can be FeSO 4 or FeCl 2 , generates HO• radicals by the interaction of hydrogen peroxide (H 2 O 2 ) with Fe 2+ .…”

Study of Biological Methods in Landfill Leachate Treatment

“…The main problem of solid waste landfills is the production of leachate and biogas due to decomposition of organic waste compounds [3]. However, mismanage- ment of solid wastes, and deficient development (non-engineered) of landfills result in soil and groundwater contamination due to leachates generated there [4]. Leachate is mainly the result of precipitation of water into the layers of buried waste and biochemical reactions of waste [5].…”
