Remoção de poluentes em wetlands de escoamento vertical com typha domingensis e carvão ativado

Abstract

This study evaluates the efficiency of vertical flow constructed wetlands in removing pollutants from secondary domestic effluent. For this purpose, prototypes were developed with varying proportions of commercial activated carbon incorporated into the filtration layer composed of coarse sand and gravel, and planted with Typha domingensis. The study analyzes physicochemical and microbiological parameters, with emphasis on the removal of organic matter, nutrients, and metals, also considering the contribution of plant biomass and the adsorption capacity of the substrates. The objective is to optimize system performance while ensuring compliance with established legal standards. The results obtained demonstrate significant improvements in wastewater treatment efficiency and reinforce the potential of Constructed Wetlands as a sustainable alternative for water resource management and environmental preservation.
