초록
본 연구에서는 황-이용 독립영양 탈질을 위한 경제적이면서도 효율적인 알칼리원의 선정을 위하여 숯, 연탄재, 패각 및 석회석을 대상으로 희분식 실험 및 연속실험을 실시하여
The purpose of this study was to select an effective and economical alkali source for sulfur-utilizing autotrophic denitrification. Tests on acid neutralization and denitrification at various alkali/sulfur mixing ratios were performed for charcoal, briquette ashes, sea shell, and limestone. The results of the experiments showed that sea shell was the most effective alkali source because it could provide more surface area than limestone, and the optimal alkali/sulfur mixing ratio was 1/1(V/V). In a sulfur/sea shell packed bed reactor, the denitrification efficiency was above 90% up to a loading rate of 116 g
