Tratamiento de Aguas Residuales de la Quebrada Colpamayo Mediante Humedales Artificiales con Schoenoplectus Californicus y Phragmites Australis

The objective of this research was to determine the efficiency of artificial wetlands with phragmites australis and schoenoplectus californicus, in the treatment of wastewater from the Colpamayo stream. The study was carried out in three phases: field, laboratory, and office. In the field phase, three artificial wetland systems were built, with the following characteristics: 0.86 m “l”, 0.43 m “w”, 0.44 m “h”, using layers of gravel, coarse sand, fine sand, and peat as material. support of the species “Phragmites australis and schoenoplectus californicus”. Finally, the wastewater from the Colpamayo stream was subjected to treatment for 72 hours, taking samples every 24 hours. The results obtained were in a retention time of 72 hours, with removals of 90% copper, 90% lead, 89% Zinc, and reductions of 90% helminths eggs, 85% thermotolerant coliforms, 84% DBO5, 82% DQO, 84% Escherichia coli, 77% Oils and fats, 98% detergents. Concluding that wetland three constituted by a combination of two plant species of phragmites australis and schoenoplectus californicus is more efficient for wastewater treatment.
