Title in Portuguese
Tratamento de lixiviado de aterro sanitário por um sistema composto por filtros anaeróbios seguidos de banhados construídos: estudo de caso - Central de Resíduos do Recreio, em Minas do Leão/RS
Keywords in Portuguese

Tratamento de lixiviado
Abstract in Portuguese
A presente pesquisa abordou o estudo em escala real do tratamento de lixiviado de aterro sanitário em um sistema composto por dois filtros anaeróbios seguidos de dois banhados construídos. O trabalho foi desenvolvido na estação de tratamento de lixiviado do aterro sanitário pertencente à Central de Resíduos do Recreio, localizada em Minas do Leão/RS. Pretendeu-se verificar a eficiência do sistema na remoção de matéria orgânica e de nitrogênio amoniacal. A fase 1 da pesquisa, que avaliou o desempenho dos filtros anaeróbios quando operados em série, indicou que a quase totalidade da remoção de matéria orgânica facilmente biodegradável ocorreu no primeiro filtro, evidenciando que, para o tratamento do lixiviado em questão, não é interessante a utilização de dois filtros anaeróbios de fluxo ascendente semelhantes em série. A fase 2 avaliou o desempenho dos filtros anaeróbios operados em paralelo e dos banhados construídos. Foi possível concluir-se que: filtros anaeróbios de fluxo ascendente são excelente alternativa para o tratamento de lixiviado de aterro sanitário, pois podem viabilizar remoções de matéria orgânica superiores a 50%; banhados construídos representam uma ecotecnologia interessante para o complemento do tratamento de lixiviado, pois podem viabilizar elevadas remoções de N-amoniacal.

Sanitary landfill leachate treatment for a system composed by upflow anaerobic filters followed by constructed wetlands: case study - Recreio Central Waste, in Minas do Leão/RS

Sanitary landfill leachate treatment
Abstract in English
This study discussed the sanitary landfill leachate treatment in a full scale system composed by two upflow anaerobic filters followed by two constructed wetlands. The research was developed at the landfill leachate treatment station owned by Recreio Central Waste, located in Minas do Leão/RS. The objective of the study was to verify the efficiency of the system in the removal of organic matter and ammonia nitrogen. The phase 1 of the study, which evaluated the performance of anaerobic filters when operated in series, indicated that almost all of the removal of organic matter readily biodegradable occurred in the first filter, showing that, for the treatment of leachate concerned, it is not interesting the use of two similar upflow anaerobic filters in series. The phase 2 assessed the performance of the anaerobic filters, operated in parallel, and the constructed wetlands. It could be concluded that: upflow anaerobic filters are excellent alternative for the sanitary landfill leachate treatment, as they may facilitate removal of organic matter greater than 50%; constructed wetlands represent an interesting eco-technology to complement the leachate treatment, which can enable high removals of N-ammonia.
