In Sequence Batch Reactor (SBR), the removal efficiencies if nutrient materials such as nitrogen and phosphate depend highly on quantity and quality of organic carbon source. Food waste thai contains abundant organic materials has been produced in ship. The applicability if anaerobically fermented if food waste (AFFW) as an external carbon source was examined in the lab-scale SBR process operated at $25^{\circ}C$. With the addition if AFFW increased, average removal efficiencies if $COD_cr$, T-N, T-P changed to $98.5\%,\;95\%,\;93\%$, respectively. Denitrification rate is 0.30g $NO_3-N/g\;VSS{\cdot}day$. In summary, it was suggested tint AFFW sould be used as an economical and effective carbon source for the biological nitrogen and phosphate removal.
