The environmental problem that generates the Mine Acid Drainage (MAD) in general in our country when these are spilled without any treatment in the riverbeds as well as the acid drainages of abandoned mines (environmental passives) that for years did not have bigger importance are the ones that motivated the present research for the resolution of an environmental and social problem. The Sulfate Reducing Bacteria (SRB) is responsible for the production of hydrogen sulfide (H2S) in anaerobiosis starting from sulfates and a donor of electrons. The sulfide produced can be used to precipitate cationic bivalents metals, allowing the bioremediation of polluted effluents. The present thesis is sought to demonstrate the environmental technical efficiency of the use of sulfate reducing bacteria isolated from places bordering the discharge points in The Villa Wetlands for the treatment of the acid drainage of the Production Unit of Cerro de Pasco belonging to the mining company Volcan. It was used as the main source of the sulfate mine drainage and as donor of electrons and source of carbon and of energy for the growth of the SRB, the manures of corral birds, sheep and cattle. The experimental trials were carried out as much for the chemical treatment as for the biogenic treatment for the first ones in batch reactors and continuous reactors and for the biogenic treatment in bioreactors anaerobes as much in systems batch as in systems in two stages for the generation of SRB and then in the contactor the reaction of precipitation of the heavy metals took place.
