Due to the low C/N ratio of domestic wastewater characteristic, addition of carbon source for the effective nitrogen removal is necessary. Methanol is widely used, but rather expensive and very dangerous in handling. Therefore, it has been required that the economic alternative carbon source must be developed.
The applicability of thermal hydrolysis reaction liquid products, which is produced during the anoxic - aerobic process, was examined in membrane bio reactor for the nutrient removal. Under the various operating conditions, nitrogen removal efficiencies using synthetic wastewater. These results, the optimal retention time was 7.0 hr, 8.0 hr for anoxic - aerobic reactor. From nitrate utilization rate test, denitrification rate was 0.02 g NO3--N / g VSS. With the addition of thermal hydrolysis reaction liquid products increased, average removal efficiencies of T-N could be increased up to 50% respectively.
