摘要: This paper presents the study of variations process parameters during transient conditions when substrates with different biodegradability were fed to a pilot-scale anaerobic digester. The two used in experiments mechanically selected organic fraction municipal solid wastes and blend separately collected wastes. Two studied: mesophilic-thermophilic passage increase loading rate thermophilic conditions. It was shown that enhanced fractions biodegradable determined greater perturbation system needed longer time reach new stable condition. volatile fatty acids concentration their indirect measure, alkalinity upon pH 4, more useful parameter understand behaviour because its sensitivity variations.
