| description | The mining is essential inside the energetic development of a country, but also it is one of the activities that affect the environment and the quality of life of the peoplewho live in the mining zones. The technology of bioremediation is based on the use of microorganisms which degrade and tranform pollutant subtances in terrestrial and aquatic ecosystems. The aim of this work was the design of an integrated physicochemical and biologicalsystem for diminishing the concentration of iron of the effluent miners by using technologies of biosorption microbial, which is formed by bioreactor and a fungus biomass for studying the efficiency of the decontamination of mine acid drainages (MAD) with heavy metals, specially the derivatives of the oxidation of the pyrite (iron). In this work were used four genus Aspergillus gfungus species and four genus Rhizopus fungus species, all these were alive and inert; besides two kind of bioreactors of fixed bed and fluidized bed and different times of residence of the water in the systemof the biofiltration were used. The elimination of iron (was of the 95.2%) was more effective in the systems of biofiltration where was employed a bioreactor f fixed bed with inert fungus biomass, with time of residence between twenty and forty minutes. In relation with the decrease of the water acidity, the PH value increased when the concentration of iron diminished. |

Los drenajes ácidos de minería (DAM), emanados de las explotaciones de carbón y minería metálica entre otros, son una de las principales fuentes de contaminación de aguas superficiales y subterráneas en el mundo. La biorremediación de los ecosistemas acuáticos contaminados se está documentando permanentemente como una alternativa eficaz, aplicada especialmente a los metales pesados que contiene. En el presente trabajo se estudió un sistema “Bioquímico” para disminuir la concentración de metales mediante biosorción microbiana. Se utilizaron biorreactores de lecho fijo y fluidizado con biomasa fúngica, se seleccionaron cuatro cepas del género Aspergillus y cuatro del género Rhizopus vivas y muertas. Los tiempos de residencia del DAM en el sistema, la temperatura y la concentración de metales pesados disueltos, especialmente los derivados de la oxidación de la pirita (hierro), fueron las variables de mayor control. Se encontró que la eliminación de hierro (95.2%) fue más eficaz en los sistemas de depuración donde se trabajó con un biorreactor de lecho fijo y biomasa fúngica inerte con tiempo de residencia entre veinte y cuarenta minutos. En lo relacionado con la acidez, los valores de pH mostraron tendencia a incrementar en la medida que disminuyó la concentración de hierro.
