The objective of this study was to investigate the effect of pretreatment method and temperature on denitrification with some external carbon source. The experimental conditions were the temperatures of 7℃, 10℃, 15℃, 20℃, and the MLSS concentration of approximately 3000 mg/L. The experiments were conducted by denitrification test for pretreated distillery wastewater, food waste, and swine wastewater of extracted supernatant(P-1), hydrolysis(P-2), acid fermentation (P-3) and acid fermentation after extract(P-4), respectively. Based on the results of the experiments, the following conclusions are drawn. The nitrate removal rate coefficients(kDN) and the specific denitrification rates(SDNR) by classified pretreatment method of carbon source were 25.9~29.5, 25.6~26.0, 18.2~ 20.8 mg NO3--N/L·hr and 9.8~11.1, 9.1~9.8, 6.9~8.5 mg NO3--N/g MLVSS·hr. Also, the temperature coefficients(θ) of methanol, pretreated distillery wastewater, food waste and swine wastewater(P-4) at the temperature(7∼20℃) were 1.061, 1.050, 1.060, 1.067, respectively. Therefore, those values were much affected for carbon source more than pretreatment method. Whereas, the swine wastewater was shown the lowest on the denitrification rate.
