초록

Foodwaste will be able to treat is 13,000 ton/day. $18{\times}10^{13}$ won/yr are wasted with the foodwaste treatment. As a result, the initial working condition. These are given as follows : On the 1st. week, the foodwaste of the 130 ton/week(digest sludge : input foodwaste = 20 : 1) is being put into a DRANCO system by the space of 2 day. On the 2nd week, the food waste of the 130 ton/week(5 day) is being put into a DRANCO system by the space of 2 day. On the 3rd week, the foodwaste of the 130 ton/week is being put into a DRANCO system by the space of 3day. On the 4th week, the foodwaste of the 350 ton/week is being put into a DRANCO system. After that time, increase the quantity than last week is 10%. Under steady-state working condition, the methane content of the biogas is more then 55%. The $NH_3-N$ content of the digest sludge is under 3,500ppm. The VFA content of the digest sludge is under 1,500ppm. The pH is more then 8. The TS content of the digest sludge is $18{\sim}22%$. The VS content of the digest sludge is under 65%.
