Removal of organic pollutants from stabilized landfill leachate by fenton coagulation and fenton like process process modeling and optimization

Abstract

Leachate is a complex liquid that originates from the municipal solid newlinewaste disposal facility through infiltration of rain water and degradation of newlineorganic substances. It contains various contaminants such as suspended solids, newlineorganic substance, heavy metals, and inorganic salts. It migrates from the newlinedisposal site through surface runoff and deep percolation and pollutes the land, newlinesurface and subsurface water resources, affecting human beings and other living newlineorganisms, either directly or indirectly. The process of leachate generation and newlinemigration begins from the disposed solid waste and extends for a very long newlineperiod even after closure of disposal site. Hence it is vital that the leachate needs newlineto be collected and treated before it is disposed off. Fenton s oxidation is a newlinesimple and low cost method used to destruct the organic substances using newlinehydroxyle radicals that are generated through the reaction of catalyst ferrous ion newlineand oxidant hydrogen peroxide under acidic pH condition. newline
