RODRIGUEZ-PIMENTEL, Reyna I; RODRIGUEZ-PEREZ, Suyén; MONROY-HERMOSILLO, Oscar  e  RAMIREZ-VIVES, Florina. Methane production as from the mixture of the urban solid waste lixiviate and municipal wastewater. Rev Cub Quim [online]. 2015, vol.27, n.3, pp.243-251. ISSN 2224-5421.

The generation of solid wastes and wastewater in Mexico , as other countries, has increased considerably of late years, so its treatment is very important to reduce the pollution. In this work are presented the results on the anaerobic digestion of lixiviate generated with the hydrolysis and acidogenesis of the organic fraction of municipal solid waste recollected in the Universidad Autónoma Metropolitana-Unidad Iztapalapa coffee shop. Theses lixiviated were diluted with municipal wastewater to different organic loads (2,3-20 gCOD/L.d) and after treated anaerobically in UASB reactor. Biogas's average production in the last load of the UASB reactor was up to 12 L/L.d with an efficiency to remove COD on top of 90 % and a production of methane of 0,38 LCH4. gSSV-1.

Palavras-chave : urban solid wastes; municipal wastewater; lixiviate; anaerobic digestion; UASB; biogas.
