Abstrakty
The aim of the study was to evaluate the effect of using biopreparations on efficiency of the co-fermentation process. Commercial bacterial biopreparations DBC Plus Type L, DBC Plus Type R5 and yeast biopreparations were used in the study. The process of cofermentation of sewage sludge with grease trap waste from a production plant that manufactured methyl esters of fatty acids was analysed in the laboratory environment under mesophilic conditions. The sludge in the reactor was replaced once a day, with hydraulic retention time of 10 days. Grease trap waste accounted for 35%wt. of the fermentation mixture. The stabilization process was monitored everyday based on the measurements of biogas volume. Addition of yeast biopreparation to methane fermentation of sewage sludge with grease trap waste caused an increase in mean daily biogas production from 6.9 dm3 (control mixture) to 9.21dm3 (mixture M3). No differences in biogas production were found for other cases (mixtures M1, M2). A similar relationship was observed for methane content in biogas.
Celem badań było określenie wpływu stosowania biopreparatów na efektywność procesu kofermentacji. W badaniach zastosowano biopreparaty komercyjne DBC Plus Typu L, DBC Plus Typu R5 (bakteryjne) oraz drożdże. Proces kofermentacji osadów ściekowych z odpadami tłuszczowymi pochodzącymi z wytwórni estrów metylowych kwasów tłuszczowych, przeprowadzono w skali laboratoryjnej w warunkach mezofilowych. Osady w reaktorze wymieniane były raz dziennie, przy hydraulicznym czasie zatrzymania 10 dni. Odpady tłuszczowe stanowiły 35% wagowych mieszaniny fermentacyjnej. Kontroli prawidłowości przebiegu procesu stabilizacji dokonywano codziennie na podstawie pomiaru ilości produkowanego biogazu. Dodatek biopreparatu z drożdży do fermentacji metanowej osadów ściekowych z odpadami tłuszczowymi spowodował wzrost średnio dobowej produkcji biogazu z 6,9 dm3(dla kontroli) do 9.21dm3 (mieszanina M3). W pozostałych przypadkach (mieszaniny M1, M2) nie stwierdzono istotnych różnic w produkcji biogazy. Podobną zależność zaobserwowano dla zawartości metanu w biogazie.
