Resumo: Nowadays, several mechanisms are used to treat wastewater, including wetland systems. This low-cost, emerging technology system shows significant results in the treatment of industrial dairy effluents on an experimental scale. The experimental systems (prototype) were built by plastic bombs, with the first stage of vertical subsurface flow and the second of horizontal subsurface flow. The effluent was stored in a reservoir and distributed by gravity, followed by root zones filled with the filter material (layers of gravel and coarse sand). The species used were Pistia stratiotes, Eichhornia crassipes and Vetiveria zizanioides, however the first species did not adapt to the system. The system showed satisfactory results regarding the COD removal efficiency of 62.13% ± 14.70, total solids 87.18% ± 2.26, turbidity 96.43% ± 3.37, total phosphorus 97.53% ± 2.15 and total nitrogen 32.08% ± 3.98. However, BOD removal was less, reaching efficiencies between 9 and 10% ± 5. The parameters of pH and sedimentable solids, on the other hand, reached the release standards established in the current legislation.

El sistema de humedales construidos son sistemas filtrantes compuestos por macrófitos acuáticos adheridos a un macizo, a través del cual discurren los efluentes. Este sistema de tecnología emergente y de bajo costo presenta resultados significativos en el tratamiento de efluentes industriales de productos lácteos a escala experimental. Los sistemas experimentales (prototipos) se construyeron utilizando bidones de plástico, siendo la primera etapa un flujo subsuperficial vertical y la segunda un flujo subsuperficial horizontal. El efluente se almacenó en un reservorio y se distribuyó por gravedad, seguido de zonas de raíces rellenas con material filtrante (capas de grava y arena gruesa). Las especies utilizadas fueron Pistia stratiotes, Eichhornia crassipes y Vetiveria zizanioides, pero la primera especie no se adaptó al sistema. El sistema mostró resultados satisfactorios en relación a la eficiencia de remoción de DQO de 62,13% ±14,70, sólidos totales 87,18% ±2,26, turbidez 96,43% ±3,37, fósforo total 97,53% ±2,15 y nitrógeno total 32,08% ±3,98. Sin embargo, la remoción de DBO fue menor, alcanzando eficiencias entre 9 y 10% ±5. Los parámetros de pH y sólidos sedimentables alcanzaron los estándares de liberación establecidos en la legislación vigente.Atualmente, utilizam-se diversos mecanismos para tratamento de águas residuárias, dentre estes o sistema de wetlands. Wetlands são sistemas filtrantes compostos de macrófitas aquáticas aderidas a um maciço, por onde o efluente escoa. Esse sistema de tecnologia emergente e baixo custo apresenta resultados significativos no tratamento de efluentes industriais de laticínios em escala experimental. Os sistemas experimentais (protótipos) foram construídos por bombonas plásticas, sendo o primeiro estágio de fluxo subsuperficial vertical e o segundo de fluxo subsuperficial horizontal. O efluente foi armazenado num reservatório e distribuído por gravidade, seguido por zonas de raízes preenchidas com o material filtrante (camadas de brita e areia grossa). As espécies utilizadas foram Pistia stratiotes, Eichhornia crassipes e Vetiveria zizanioides, porém a primeira espécie não se adaptou ao sistema, que apresentou resultados satisfatórios em relação à eficiência de remoção de DQO de 62,13% ±14,70, sólidos totais 87,18% ±2,26, turbidez 96,43% ±3,37, fósforo total 97,53% ±2,15 e nitrogênio total 32,08% ±3,98. Porém, a remoção de DBO foi inferior, atingindo eficiências entre 9 e 10% ±5. Já os parâmetros pH e sólidos sedimentáveis atingiram os padrões de lançamento estabelecidos na legislação vigente.Research, Society and Development2022-06-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3052010.33448/rsd-v11i8.30520Research, Society and Development; Vol. 11 No. 8; e12811830520Research, Society and Development; Vol. 11 Núm. 8; e12811830520Research, Society and Development; v. 11 n. 8; e128118305202525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/30520/26337Copyright (c) 2022 Gislene da Conceição Marcelino; Anderson de Assis Moraishttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMarcelino, Gislene da Conceição Morais, Anderson de Assis 2022-07-01T13:34:06Zoai:ojs.pkp.sfu.ca:article/30520Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:14.659389Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
