Uso de macrófitas aquáticas no tratamento de efluente industrial

Abstract

Contributing to the sustainable development within the proposal to use low cost natural treatment systems, in order to promote a biological and clean alternative, to know the physicochemical parameters that can influence the development of floating aquatic macrophytes. Since some species of aquatic macrophytes remove chemical elements, the objective of the present work was based on the potential of two floating aquatic macrophyte species Pistia stratiotes and Lemna Gibba to remove chemical elements from textile industrial effluent, as well as to verify the development of these species under the effluent they underwent. The research work was installed at the Federal Institute of Piauí-Campus Teresina Central. Three repetitions were performed for each species and three more for the control element, totaling nine repetitions. In the plant, the adaptation evaluations of the plants in relation to the effluent and their quantity were carried out in a determined period of detention. In the effluent, a physical chemical characterization was performed comparing the two macrophyte species as well as the control repetition.
