摘要: Solid waste biodegradability is a key parameter to control and optimize high solid anaerobic digestion (HSAD) of biowaste (BW) residual municipal (RMSW). It enables assess the biomethane potential biostability achieved by process. The objective this study was correlate biochemical methane (BMP) with selected analytical parameters commonly used predict bioreactivity organic samples, such as global analyses (VS, TOC, CODTot N-TKN), (humic substance index, Van Soest fractionation method, total lipid content, protein content), leaching behaviour (VFA, CODSol, N-TKN N-NH3), respirometric activity (i.e. BOD on samples suspended in liquid medium, for study). data set obtained analysing listed above two RMSW BW, collected from three full-scale HSAD plants, their respective digestates produced plants altogether 4 wastes digestates). principal component analysis showed that VS, COD, TOC were partly redundant could be significantly reduced. Predicting single fractions not found relevant. On opposite, fraction RES HSI most correlated BMP BOD. These variables constitute good indicators description (and biostability) it.
