제지슬러지의 혐기메탄발효 = Originals : Methane Fermentation of the Paper Mill Sludge under Anaerobic Condition

다국어 초록 (Multilingual Abstract)

The activated paper mill sludge was treated with WF and some additives (sodium sulfide, nickel nitrate, ethyl acetate) for methane fermentation at 35 C. Optimum C/N ratio was 60 out of three conditions (20, 30 and 60). The period of 40% of methane content, possibly ignition, was 2 days shorter than with non-treatment during 10 days. Nevertheless, the total amount of methane production showed the 1/8 level of control for the same period. The yield and content of methane were increased by the addition of sodium sulfide and ethyl acetate. Sulfur was an essential factor in methane fermentation of paper mill sludge.
