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.
