Resumo: | A system consisted of two parallel vertical flow constructed wetlands treating effluent of an activated sludge plant were studied in order to evaluate the potential for nitrification, removal of turbidity, and removal of total suspended solids. The prototype was installed in a location for large events. The two beds were vegetated with the macrophyte Typha sp. The beds dimensions were 2.50 m long, 1.10 m wide and 1.20 m height making up a surface area of 2.75m2. The filter medium was composed of the following layers: top – 0.07m of gravel, intermediate – 0.60m of medium sand, and bottom – 0.13m of gravel. The system effluent was also evaluated in order to verify its adequacy to use for agricultural irrigation. The following variables were quantified: COD, TSS, turbidity, ammonia-N, nitrate and pH. The system was evaluated over 160 days demonstrating a potential treatability and robust buffer capacity for high loads, especially for short events, around 2-3 continuous days, serving a population up to 3,000 people. The system accomplished 40% nitrification, despite the low pH range (6.25 to 3.69), producing an effluent with an average concentration of 29.5 mgL-1 N-NO3. Values obtained for TSS (93.85% efficiency, concentrations: 37.4 mg L-1 influent, and 2.3 mg L-1 effluent), Turbidity (97% efficiency, concentrations: 31.1 NTU influent, and 1.0 NTU effluent), COD (efficiency 74%, concentration: 114.7 mg L-1 influent and 29.9 mgL-1 effluent) characterized an excellent quality of the final effluent for reuse in agriculture. |

O meio filtrante foi constituído das seguintes camadas: topo - 0,07 m de brita 01, intermediária - 0,60 m de areia média, fundo - 0,13 m de brita 01. O sistema experimental foi implantado na área de eventos, Estância Árvore da Vida localizada no município de Sumaré/SP e foi suprido pelo efluente da Estação de Tratamento de Esgotos (ETE) do local que utiliza o sistema de lodos ativados. Avaliou-se o potencial de nitrificação, redução de turbidez e sólidos suspensos totais (SST) com vistas à produção de água adequada ao reuso, quantificando-se as seguintes variáveis: Demanda Química de Oxigênio (DQO), SST, Turbidez, N-amoniacal, Nitrato e pH. O sistema foi avaliado ao longo de 160 dias demonstrando um potencial de tratabilidade robusto e capacidade tampão para altas cargas, fenômeno perceptivo, especialmente, durante eventos não muito longos, em torno de 2 a 3 dias ininterruptos com população contribuinte de até 3.000 pessoas. O sistema efetivou 40% de nitrificação, apesar da baixa faixa de pH (6,3 a 3,7), produzindo um efluente com concentração média de N-NO3 de 29,5 mgL-1. Valores obtidos para SST (eficiência 93,85%, concentrações: afluente 37,4 mg L-1 e efluente 2,3 mgL-1), Turbidez (eficiência 97%, concentrações: afluente 31,1 NTU e efluente 1 NTU) e DQO (eficiência 74%, concentrações: afluente 114,7 mgL-1 e efluente 29,9 mgL-1) caracterizaram o efluente final com possibilidade de emprego para reuso na agricultura dependendo da cultura e solo a se utilizar.Universidade Federal de Viçosa - UFV2016-03-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/48610.13083/reveng.v23i6.535Engineering in Agriculture; Vol. 23 No. 6 (2015); 517-528Revista Engenharia na Agricultura - REVENG; v. 23 n. 6 (2015); 517-5282175-68131414-398410.13083/reveng.v23i6reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/486/341Ferreira dos Santos, Regina MariaRoston, Denis Miguelinfo:eu-repo/semantics/openAccess2023-01-19T13:22:54Zoai:ojs.periodicos.ufv.br:article/486Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:22:54Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
