MADERA-PARRA, Carlos A. Landfill leachate treatment by technological coupling of High Rate Anaerobic Pond-BLAAT^® and Subsurface horizontal flow constructed wetlands. Ing. compet. [online]. 2020, vol.22, n.2, 9740.  Epub Nov 30, 2020. ISSN 0123-3033.  https://doi.org/10.25100/iyc.v22i2.9740.

Landfill leachate is a residual liquid with a great eco-toxicological potential that is generated as a product of the mixture of rainwater that is infiltrated in the buried solid waste, of assisted water by biochemical processes inside the landfill and of water content from the waste itself. Eco-technologies (constructed wetlands, algae ponds) have been used for landfill leachate treatment due to ecological and environmental advantages with quite promising results. In this sense, the present research carried out in 2015 in Presidente Landfill, San Pedro municipality, Valle del Cauca, Colombia, was oriented to evaluate at pilot scale the coupling technology Biorreactor High Rate Anaerobic Pond-BLAAT ® + constructed wetlands planted with polyculture of tropical species Colocasia, esculenta-Ce, Heliconia psittacorum-He y Gynerium sagittatum-Gs, for the treatment of landfill leachate under American tropical conditions. This work makes available a series of field data on the quality of raw leachate and effluent from each treatment technology, showing the performance of the coupling, which may contribute to the establishment of conditions and scenarios for the treatment of this in populations that have cultural and environmental conditions similar the area of this study.
