Resumo: The laundries sludge has varied chemical composition, and it is considered inadequate for disposing of in sanitary landfill. So, this work presents the physical-chemical characterization of this textile sludge for the study of cement-based solidification /stabilization (S/S) with the addition of Portland cement - CPII F32 or CP II Z. COD total, fixed and volatile solids, density, pH, and the presence of metals were analyzed. Cylindrical samples of paste with 10%, 20% and 30% addition of sludge were submitted to compressive strength tests according to NBR-7215 ABNT norm, and leaching tests according to NBR 10005 ABNT norm. The results demonstrated that in the cement/sludge paste, the values of mechanical resistance of 28 days can be superior to 10 MPa. The beginning of curing period was retarded when the proportion of sludge addition to the cement increases, but maintaining its same order of greatness. Also, the leaching found in the samples of paste without incorporating sludge is about the same order of greatness of that found in samples containing sludge. This allows concluding that the paste permits a safe incorporation of the metals detected in the textile sludge. The presence of metals Fe, Mg, Al, Si, Ca, Cr, Co, Cu, Mn and Zn was detected in the sludge

O lodo tem composição química variada sendo classificado como perigoso, não podendo ser depositado num aterro sanitário. Neste trabalho apresenta-se a caracterização físico-química do lodo têxtil de uma lavanderia industrial, para o estudo de sua disposição final. Nesta caracterização analisaram-se: DQO, sólidos totais, fixos e voláteis no lodo, densidade, pH, e a presença de metais, sendo detectado a presença dos metais Fe, Mg, Al, Si, Ca, Cr, Co, Cu, Mn e Zn. Corpos de prova de lodo/cimento, nas dosagens de 10%, 20% e 30% de lodo em relação ao cimento, foram submetidos à análise de resistência a compressão, tempo de pega e testes de lixiviação por batelada.Os resultados demonstraram que na pasta de lodo/cimento, os valores de resistência mecânica aos 28 dias, atingem valores maiores que 10 MPa. A adição de lodo ao cimento influenciou o tempo de pega retardando o início, mas mantendo o tempo decorrido entre o início e o final da pega. Também, a lixiviação ocorrida nas amostras de pasta sem a incorporação de lodo é da mesma ordem de grandeza que nas amostras que contém lodo. Isto nos permite concluir que a pasta permite uma segura incorporação dos metais contidos no lodo têxtilUniversidade Estadual De Maringá2008-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/155210.4025/actascitechnol.v26i1.1552Acta Scientiarum.
