Resumo: This study aimed to evaluate the influence of nutrient loading and species cultivated in removing K, Na, Cu and Zn from swine wastewater treated in constructed wetlands (SACs). The experiment consisted of eight SACs, built on a pilot scale. SAC3, SAC5, SAC7 and SAC9 were planted with Tifton-85 bermudagrass (Cynodon spp.) and SAC2, SAC4, SAC6 and SAC8 were planted with cattail (Typha latifolia). The difference in load was made by applying different inflows to the SACs, corresponding to loading rates of potassium (TCK), sodium (TCNA), copper (TCCu) and zinc (TCZn) of 21.6, 15.2, 0.017 and 0.140 (SAC2 and SAC3), 43.4, 30.6, 0.035 and 0.281 (SAC4 and SAC5), 61.1, 43.0, 0.05 and 0.395 (SAC6 and SAC7), and 74.4; 52.4, 0.060 and 0.481 kg ha-1 d-1 (SAC8 and SAC9). The variables were statistically evaluated in a 2 x 4 factorial (2 species and 4 rates of nutrient loading) in a randomized block design. It has been found that neither the applied load nor the type of species cultivated influenced the removal of Na, Cu and Zn from the SACs, except for K, for which the load applied influenced the removal of this constituent.
