Anaerobic digestion of wastes containing pyrolignitic acids / V. Andreoni, P. Bonfanti, D. Daffonchio, C. Sorlini, M. Villa. - In: BIOLOGICAL WASTES. - ISSN 0269-7483. - 34:3(1990), pp. 203-214. [10.1016/0269-7483(90)90022-K]
Abstract:
Small quantities of residues from wood pyrolysis (pyrolignitic acids) added to swine slurry were digested in two laboratory anaerobic, fixed-bed, upflow digesters, filled with wood-chips or PVC as support media.
The two digesters showed about the same efficiency when treating swine slurry containing pyrolignitic acids up to 6·5% (v/v). With a 10% (v/v) concentration, COD removal efficiency, specific biogas production, pH of the effluent, utilized as process-efficiency parameters, decreased remarkably for both plants. However, the digester with wood-chips showed a stronger resistance to the presence of pyrolignitic acids.
