Resumo: | Bioretention column are widely used to evaluate the performance of these structures in the removal of pollutants, and to investigate different conceptions of filter media to improve their efficiency. However, there is no standard nor a scientific recommendation on adequate diameters of bioretention columns (DBC), or even which are the uncertainties related to the transfer of results between the different scales of the study. In this study, the effect of the diameter of experimental bioretention columns with two types of filter media on the retention and removal of pollutants from stormwater runoff was evaluated. Bioretention columns with diameters of 400 mm, 300mm and 200mm were submitted to a synthetic stormwater dosage regime and experimentally evaluated to water retention and pollutants removal (TSS, nitrite, nitrate and phosphate). Two types of media filter were used, a conventional (gravel, sand and local soil) and a modified filter media (gravel, sand, local soil and sugarcane bagasse). The results showed that the runoff retention was not affected by the DBC, but yes by the time interval between stormwater dosages. Bioretention with conventional media were slightly more efficient in the runoff retention (34.8%) compared to those with modified media (33.8%). Both types of filter media increased the values of pH and electrical conductivity of the stormwater. Color and turbidity parameters decreased in the media with sugarcane bagasse (33.6% and 50%, respectively), and increased in the conventional media (56% and 9.1%, respectively). The removal of TSS (98%), nitrite (98%) and phosphate (94%) showed no variability among different medias and diameters. Nitrate removal was influenced by the filter media and, mainly, among the DCB. Nitrate exports (-116%) were observed in the bioretention columns with conventional filter media with 400 mm of diameter, as well as the columns with sugarcane bagasse (-94.7%). Bioretention with sugarcane bagasse removed less nitrate in the columns with 300 mm (6%) and 200 mm (32.2%) compared with the columns with conventional filter media (89% and 93%, respectively). The addition of sugarcane bagasse in the filter media contributed to the leaching of nitrate and to the rapid saturation of the filter media, affecting their efficiency in removing pollutants and retention of stormwater. About the pollutants evaluated, the scale effect of the bioretention columns was verified on the performance of nitrate removal, and in bioretention with modified filter media with sugarcane bagasse. |

No entanto, não há uma padronização, e nem mesmo uma recomendação científica sobre diâmetros de colunas de biorretenções (DCB) adequados, ou mesmo quais as incertezas relacionadas à transferência de resultados entre as diferentes escalas do estudo. Nesse estudo, foi avaliado o efeito do diâmetro de colunas experimentais de biorretenção, com dois tipos de mídia filtrante, na retenção e na remoção de poluentes do escoamento pluvial. Colunas de biorretenção com diâmetros de 400 mm, 300 mm e 200 mm foram submetidas a um regime de dosagem de escoamento pluvial sintético, e avaliadas experimentalmente com relação à retenção do escoamento pluvial e remoção de poluentes (SST, nitrito, nitrato e fosfato). Foram utilizados dois tipos de mídia filtrante, uma convencional (brita, areia e solo local) e uma mídia filtrante modificada (brita, areia, solo local e bagaço de cana-de-açúcar). Os resultados demostram que a retenção de escoamento não foi afetada pelo DCB, mas sim pelo intervalo de tempo entre dosagens de escoamento pluvial. As biorretenções com mídias convencionais foram ligeiramente mais eficientes na retenção do escoamento (34,8%) em relação àquelas com mídia modificada (33,8%). As biorretenções elevaram os valores de pH e condutividade elétrica do escoamento pluvial nos dois tipos de mídia filtrante. Os parâmetros cor e turbidez tiveram decréscimo nas mídias com bagaço de cana-de-açúcar (33,6% e 50%, respectivamente), e acréscimos na mídia convencional (56% e 9,1%, respectivamente). A remoção de SST (98%), nitrito (98%) e fosfato (94%) não apresentou variabilidade entre as biorretenções com diferentes diâmetros e mídias filtrantes. A remoção de nitrato variou entre os tipos de mídia filtrante e, principalmente, entre os DCB. Foi observada exportação de nitrato (-116%) nas colunas de biorretenção com mídia filtrante convencional e com diâmetro de 400 mm, bem como nas colunas com bagaço de cana-de-açúcar (-94.7%). As biorretenções com bagaço de cana-de-açúcar removeram menos nitrato nas colunas de 300 mm (6%) e 200 mm 32,2%) em comparação com as colunas com mídia filtrante convencional (89% e 93%, respectivamente). A adição do bagaço de cana-de-açúcar na mídia filtrante contribuiu para a lixiviação do nitrato e para a rápida saturação da mídia filtrante, afetando a sua eficiência na remoção de poluentes e na retenção do escoamento pluvial. Com relação aos poluentes avaliados, verificou-se o efeito escala das colunas das biorretenções no desempenho da remoção do nitrato, tanto nas biorretenções com mídia filtrante convencional, como nas biorretenções com mídia modificada com bagaço de cana-de-açúcar.Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de TecnologiaTassi, Rutineiahttp://lattes.cnpq.br/7584743367186364Wolff, Delmira BeatrizGeorgin, JordanaMartins, José Rodolfo ScaratiGiacomoni, Márcio HofheinzPivetta, Glaucia Ghesti2022-08-26T13:13:49Z2022-08-26T13:13:49Z2022-06-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/26001porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2022-08-26T13:13:49Zoai:repositorio.ufsm.br:1/26001Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-08-26T13:13:49Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
