摘要: Population growth has contributed to increasing poultry production, entailing a high waste loading, mainly litter. One of the alternatives treat such residues is anaerobic digestion, in which digester startup and generated-digestate quality are related material be digested operation conditions, wherein inoculum use one factors. This study therefore aimed investigate how digestates, as inocula, influence litter (PL) well reduction solids chemical oxygen demand (COD). For this, two inocula (bovine swine digestates) were tested digestion process. The added at loads 0.67, 1.00 1.67 gVS.L -1 day . A split-plot design was developed data underwent analysis variance with means compared by Tukey's test 5% significance. Concerning bovine it concluded that both indicated However, better because had removal total (TS), volatile (VS) COD.
