Digestão anaeróbia de resíduos vegetais com baixa concentração de sólidos em reator compartimentado.

Abstract

Waste Anaerobic Digestion Plant with Low Concentration of Solids Reactor Compartmented. In Brazil, the solid wastes of plant and animal origin , account quantitatively for 55 % of municipal solid waste. Anaerobic digestion is an important alternative for the treatment of waste with high concentrations of putrescible organic materials , considering incorporating low operating costs and produce clean energy source . The experimental apparatus of this work consisted of an anaerobic baffled reactor and unit shredding solid waste and ancillary equipment . The waste mass was composed of ten different types of wastes collected in central supply , transported to the laboratory and subjected to grinding and screening . The efficiency of biostabilization the mass of COD was 54.1 % , providing methane production rate of 0.13 LCH4 . g -1COD . Considering the significant mass of carbonaceous material on the substrate, the production rate of methane was relatively low , compared to the time monitoring fifty days. Keywords: combined anaerobic treatment , solid waste, energy potential .
