| Abstract: | The article discusses possibilities of municipal wastewater treatment in various types of anaerobic reactors (UASB, UAF, AnSBR). The temperature during corresponding laboratory experiments varied between 9–23?°C. Real wastewater from WWTP Bratislava-Petr?alka and synthetic substrate were used in the experiments. The HRT values for reactors were found to be 10–46?h. Treatment of municipal wastewater with the AnSBR and UAF system has shown more positive results in laboratory scale studies then the UASB system. The mean removal efficiency of COD depended on the type of anaerobic reactor, temperature, used HRT and was found between 37–48% (UASB), 56–88% (AnSBR) and 46–90% (UAF). |
