| Popis: | The paper describes the anaerobic digestion of biomass of microalgae and bacteria from the treatment of wastewater from municipal sources and malt house. During the three series of experiments the influence of primary sludge addition, type of biomass and the substrate to inoculum ratio on anaerobic digestion and biogas production was investigated. The results showed that the composition of the substrate plays an important role. Digesters with added primary sludge reached stationary phase faster than without added sludge digesters but the specific biogas production was not higher. Regarding the suitable substrate to inoculum ratio the most suitable ratio is 2:1 (inoculum:biomass). Biomass from municipal wastewater treatment produced up to 186 L kg−1 OM at 2:1 ratio of inoculum to biomass. Substrate from malt house wastewater treatment produced less biogas, 126 L kg−1 OM at 2:1 ratio of inoculum to biomass. Methane content in the gas at the end of the experiment varied between 60 and 75 %. |
