Method for treating sanitary landfill leachate by oxidizing process anu00d3dica.

摘要

This invenu00c7u00c3o is related to the development of an innovative method for the treatment of sanitary landfill leachate. This innovative method consists of subjecting the effluent to a process of eletru00d3lise using as material of elu00c9trodo the boron doped diamond (snad), lead oxide (PB02) and stainless steel (SS) in the combinations anode cu00c1todo: distributed database distributed database, distributed database PbO2 SS or SS.An electric current is applied to the elu00c9trodos direct whose intensity can vary between 100 and 4000 for each m2 area of anu00d4do, can also be added a source of chlorides, with concentrations up to 4 g L.The compounds are oxidized by an oxidizing agent eletrogerados pollutants from species present in the effluent, allowing its complete destruction, for conversion into biodegradu00c1veis compounds, or by complete mineralisation to carbon dioxide, water and inorganic salts. This method allows you to remove by dumping catu00d3dica the heavy metals present in the effluent.
