Balanço de massa de reatores anaeróbios de fluxo ascendente com manta de lodo (UASB) em série, tratando águas residuárias de suinocultura.

Abstract

The anaerobic digestion is a process of treatment of organic residues that presents more favorable energy rocking when compared with the aerobic processes. In this work estimation of mass balance to leaving of the values of the determination of chemical demand of oxygen (DQO) , sludge solid volatile and production of CH4 in reactors UASB in scale pilot installed in series. It was verified that the total DQO removed converted into CH4 varied of 10,8 67.8% and the DQOCH4 relation for dissolved DQO removed of 0,72 the 2,57, indicating high participation of the physical removal of solids of the tributary of 37 95%. The volumetric organic loading rate (TCOV) influenced in the performance of the system.
