Horizontal biodigestor behavior at poultry litter treatment; Comportamento de um biodigestor horizontal no tratamento de cama de frango de corte

Abstract

This paper evaluated the biogas production and organic matter removal at poultry litter treatment in anaerobic horizontal reactor. The poultry litter was diluted with deionized water at a ratio of 5.6% of volatile solids (SV). It was used an organic load of 1.87 g SV L{sub biodigestor} {sup -1} day{sup -1} with hydraulic retention time of 30 days and 30 days for repetition. The evaluations were made daily, with TS, VS and biogas production analyses. The bioreactor stability was verified weekly, using the relation volatile acidity (VA)/total alkalinity (TA). It was utilized the Minitab 15 software, doing the statistical descriptive analysis of the data relative to biogas production, % of TS and VS removed. It was evidenced the variable 'biogas liters' has shown the largest variation coefficient, with a 1.28 L production at the 25 deg day. The average value for biogas production was 0.56 L day{sup -1} and the average values for TS and VS were 52,39 e 63,66 %, respectively. According to the Anderson Darling test, all the variables presented normality at the 5% significance. The process has shown stability through the VA/TA relation and it was concluded that it may be used at the poultry litter treatment.  More>>
