Mining, lead, biological agents, bioremediationAbstract
In the mining industry, wastewater effluents are mainly contaminated with heavy metals such as mercury, lead, chromium and zinc. These effluents require pretreatment before discharge into water bodies to comply with environmental regulations. This project focuses on a literature review on wastewater bioremediation using biological agents (bacteria, algae, fungi, plants), which stand out for their ability to adsorb and degrade heavy metals. The objective is to identify the most effective biological agent in the adsorption of metals present in mining wastewater. Subsequently, experimental practices will be carried out using pure water contaminated with metal concentrations according to the literature. This mixture will be treated in a stabilization pond with the selected agent, evaluating its adsorption capacity and reaction times to optimize the pretreatment of mining waters, complying with Colombian regulations for discharge into surface water bodies.
