Biofiltración de metales pesados en aguas del rio amarillo por medio de humedales construidos con base en residuos agroindustriales

Abstract

When considering water quality and conservation, subsurface flow wetlands are an economically viable option, with effective results in the removal of pollutants from water bodies that are affected by mining waste. Artificial wetlands are very versatile because they implement ecosystem recovery techniques that are linked to water bodies. These biofilters are able to retain a variety of heavy metals. The main objective of this paper is the evaluation of subsurface flow wetlands constructed at laboratory scale and their potential application in the treatment of bodies of water contaminated by heavy metals. The design and construction of the wetlands was carried out in the El Pache sector, where the sample was taken. The wetlands have the following dimensions: 0.40 cm long, 0.20 cm wide and 0.18 cm high.
