摘要: Constructed wetlands are one of the best technologies for wastewater treatment in small towns, businesses or farms and/or livestock breeding. In this work, a depuration ecological system implemented hybrid constructed wetland to remove nutrients and organic matter from urban agglomerations is studied. It comprises two processing stages: primary carried out hydrolytic up-flow sludge bed digesters working parallel secondary made up vertical flow wetlands, which alternatively used, followed by horizontal wetland. An internal recirculation connects output input with aim promoting nitrification-denitrification process. High removal efficiencies were observed when treating highly polluted an animal farm. Therefore, system, designed enhance nitrogen reduction, may be considered efficient alternative treat diffuse contamination agricultural industries polluting surface waters nitrates, cause serious environmental problems, such as eutrophication.
