【 摘 要 】

The aim of this work was to study the constructed wetland system for the treatment of water from the Corumbataí river simulated on a laboratory scale. The parameters analyzed at different points of the system were ammonia, biochemical demand for oxygen (BDO), chemical demand for oxygen (CDO), chlorides, apparent color, conductivity, dissolved oxygen, magnesium (Mg), sodium (Na), potassium (K), silicon (Si), total phosphorous, total coliforms and Escherichia coli, total dissolved solids (TDS), turbidity, and macrophyte biomass. The results demonstrated that this alternative water treatment system was effective in removing the microorganisms (total coliforms and E. coli), among other parameters analyzed, for varying periods of the treatment, promoting notable improvement in the quality of the water treated from the Corumbataí River.
