Resumo: | This paper analyzes the removal of colour and phenol found in pulp and paper industry wastewater using advanced technologies: (i) coagulation-flocculation-sedimentation, (ii) granular activated carbon fltration, (iii) combination of coagulation-flocculation-sedimentation and granular activated carbon fltration. Jar tests and bench-scale column tests were performed. The main results obtained were: removals of 89% and 60% for colour and phenol, respectively, using coagulation-flocculation-sedimentation; for activated carbon fltration, overall colour and phenol removal of 45% and 47%, respectively; and maximum removals obtained were 99% for colour and above 93% for phenol, when the complete cycle (coagulation-flocculationsedimentation combined with fltration) was tested. Along with this last treatment, it was possible to obtain a high quality fnal efuent and to comply with the environmental regulations in several aspects. |

Trata-se de um efluente parcialmente biodegradável, entretanto, parte considerável dos componentes presentes nesses efluentes são dificilmente removidos em processos biológicos convencionais de tratamento de águas residuárias. Assim, estudar formas de melhoria da qualidade final desses efluentes, a partir de tecnologias mais avançadas de tratamento, vai de encontro à inovação tão almejada por esse setor altamente competitivo e globalizado, que é o mercado da celulose e papel. O presente artigo teve como enfoque a remoção de cor e fenol a partir do emprego da coagulação/floculação/sedimentação empregando tanino vegetal como agente coagulante, em detrimento ao uso de coagulantes sintéticos convencionais e filtração em carvão ativado granular (CAG). Os principais resultados obtidos foram remoções de: 89% da cor e 60% do fenol no tratamento por coagulação, floculação e sedimentação; 45% da cor e 47% do fenol no tratamento por filtração em carvão ativado e 99% da cor e acima de 93% de fenol ao tratar o efluente por ciclo completo (coagulação, floculação, sedimentação seguido de filtração). Com esse último tratamento foi possível obter efluente final com elevada qualidade e atender à legislação ambiental sob diversos aspectos.Universidade Federal de Santa Maria2019-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3250310.5902/1980509832503Ciência Florestal; Vol. 29 No. 2 (2019); 571-582Ciência Florestal; v. 29 n. 2 (2019); 571-5821980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32503/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessBender, Ana FláviaSouza, Jeanette Beber deVidal, Carlos Magno de Sousa2019-09-05T20:18:10Zoai:ojs.pkp.sfu.ca:article/32503Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-09-05T20:18:10Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
