Abstract
This study proposed a new sewage treatment system that combined a two-step UASB reactor (for removal of organics and denitrification) and an aerobic biofilm reactor. The laboratory-scale, combined system had been operated for 210 days by feeding a low-strength synthetic wastewater simulating domestic sewage. The combined system exhibited a very satisfactory performance in organics and nitrogen removal (achieving the removal rate of 91% and 61% respectively) at a HRT of only 4.7 h under the temperature range between 10 and 20°C with a circulation ratio of 2. Vial activity tests of retained sludge in the UASB reactor were conducted after the 210 days' operation.
