열-알칼리 전처리를 통한 음식물류 폐수 부상 스컴의 가용화 = Disintegration of Flotation Scum in Food Wastewater Using Thermo-Alkaline Pretreatment

다국어 초록 (Multilingual Abstract)

This study was performed to optimize the integrated thermal-alkali pre-treatment of flotation scumfor the enhanced biodegradability. The optimum conditions of the integrated thermal-alkali pre-treatment wereobtained using response surface methodology. The disintegration degree of carbohydrate (69.2%) and protein (57.3)were estimated under the optimum conditions. Although the optimum conditions were different, the disintegrationdegrees were similarly. A fermentative hydrogen batch test was conducted to evaluate the hydrogen productionfrom scum with and/or without. The maximum hydrogen production from scum with pre-treatment was of 0.64mol H2/mol hexoseadded, which about 1.4 times higher than without pre-treatment.
