Resumo: | Three anaerobic filters with upflow were operationally evaluated for the treatment of wastewater from the coffee cherries processing (ARC). The reactors were made with PVC tube with total volume for 139.5 L. They were operated under environmental temperature varying from 13.8 to 24.4 ºC. The ARC had the pH corrected with whitewash to values up to 7 and the concentration of nutrients to relationship DBO/N/P equal 100/5/1. The volumetric organic load rate and hydraulic retention time varied from 1.49 to 12.99 kg m-3 d-1 and 32.3 to 56.9 h, respectively. The filters were monitored, by collecting both the affluent and effluent samples of the filters, and quantifying the variables: COD, BOD, phenolic compounds, pH, alkalinity and volatile acids. At the end of the evaluated conditions it observed that the great oscillation in the hydraulic and organic load did with that the anaerobic filters used in this work operated in an unstable condition, presenting unbalance between the producers and consumers of volatile acids, with production no satisfactory of alkalinity bicarbonate. However, the affluent and effluent pH values were inside of the range of appropriate values so that it has the anaerobic degradation of the organic material. The filters didn’t support the organic shock load rate, what reduced the efficiency of removal of organic matter drastically and phenolic compounds. Based on the results of performance and conditions operational, it is conclude that the maximum organic load rate to be applied in anaerobic filters for treatment of ARC, it should not exceed 2 kg m-3 d-1 of DQO. |

Os filtros, confeccionados com tubos PVC, preenchidos com brita nº 2 e com volume total de 139,5 L, foram operados sob temperatura ambiente, que variou de 13,8 a 24,4 ºC. A ARC teve o pH corrigido com cal até valores próximos a 7. A concentração de nutrientes foi corrigida mantendo-se relação DBO/N/P igual a 100/5/1. A carga orgânica volumétrica e o tempo de residência hidráulica variaram de 1,49 a 12,99 kg m-3 d-1 e de 32,3 a 56,9 h, respectivamente. O monitoramento foi realizado com a coleta de amostras afluentes e efluentes dos filtros, quantificando-se as variáveis DQO, DBO, compostos fenólicos, pH, alcalinidade e ácidos voláteis. Como resultado, observou-se que a grande oscilação na carga hidráulica e orgânica fez com que os filtros anaeróbios, utilizados neste trabalho, operassem de forma instável, apresentando desequilíbrio entre os micro-organismos produtores e consumidores de ácidos voláteis, com produção não satisfatória de alcalinidade na forma de bicarbonato. No entanto, os valores de pH afluente e efluente mantiveram-se dentro da faixa de valores adequados para que ocorresse a degradação anaeróbia do material orgânico. Os filtros não suportaram o choque de carga orgânica, o que reduziu drasticamente a eficiência de remoção de matéria orgânica e de compostos fenólicos. Com base na análise de desempenho e nas condições operacionais empregadas, a carga orgânica máxima a ser aplicada em filtros anaeróbios para tratamento de ARC, não deve exceder 2 kg m-3 d-1 de DQO.Universidade Federal de Viçosa - UFV2011-01-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/25010.13083/reveng.v19i1.277Engineering in Agriculture; Vol. 19 No. 1 (2011); 62-71Revista Engenharia na Agricultura - REVENG; v. 19 n. 1 (2011); 62-712175-68131414-398410.13083/reveng.v19i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/250/193Fia, RonaldoMatos, Antonio Teixeira deSchuery, Filipe CruzTeodoro, Pedro Emílio PereiraLuiz, Fátima Aparecida Resendeinfo:eu-repo/semantics/openAccess2023-01-19T12:50:21Zoai:ojs.periodicos.ufv.br:article/250Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:50:21Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
